Bringing Energy Down to EarthSay energy. Think environment.And vice versa.Any company that is energy conscious is also environ-mentally conscious. Less energy consumed meansless waste, fewer emissions and a healthierenvironment.

In short, bringing energy and environment togetherlowers the cost industry must pay for both. By helpingcompanies manage energy, Armstrong products andservices are also helping to protect the environment.

Armstrong has been sharing know-how since weinvented the energy-efficient inverted bucket steamtrap in 1911. In the years since, customers’ savingshave proven again and again that knowledge notshared is energy wasted.

2. Specify size of pipe connection.When flanges are required,specify type of flange in detail.

3. Specify maximum workingpressure that will beencountered.

4. Specify orifice size.

5. Specify any options required.

This section only highlights thecomplete trap selection informationavailable in the Armstrong SteamConservation Guidelines for Con-densate Drainage, Handbook N-101.Armstrong’s Software Program 1(Steam Trap Sizing and Selection)is designed to be used in conjunc-tion with Handbook N-101 and thiscatalog. If you do not have Hand-book N-101 or your free copy ofSoftware Program 1, contact yourArmstrong Representative.

Actual installation and operation ofsteam trapping equipment shouldbe performed only by experiencedpersonnel. Selection or installationshould always be accompanied bycompetent technical assistance oradvice. This catalog or its accompa-nying handbook should never beused as a substitute for suchtechnical advice or assistance.We encourage you to contactArmstrong or its local representativefor further details.

Basic ConsiderationsUnit trapping is the use of a sepa-rate steam trap on each condensingunit including, whenever possible,each separate chest or coil of asingle machine.

You’ll select most traps with theaid of past experience. Either yours,the know-how of your ArmstrongRepresentative/Distributor or whatothers have learned in trappingsimilar equipment.

Do-it-yourself sizing is simple withthe aid of Armstrong SoftwareProgram 1. Even if you don’t haveaccess to this computer program,trap sizing is easy when you knowor can figure:

1. Condensate loads in lbs/hr.2. The safety factor to use.3. Pressure differential.4. Maximum allowable pressure.

Safety Factor or Experience FactorSteam mains. Select traps todischarge condensate produced byradiation losses.

Traps installed between the boilerand the end of the steam main: 2:1.

Traps installed at the end of themain or ahead of reducing andshutoff valves that are closed partof the time: 3:1.

Steam tracer lines. On mosttracer line applications, the flow tothe steam trap is surprisingly low.Therefore, the smallest trap isnormally adequate.

Process equipment. Differentapplication requirements involvingconstant or variable steam pressuredetermine which type of trap shouldbe used. The safety factor is depen-dent upon the type of equipmentbeing drained and the pressure.

I. Constant Steam PressureA 2:1 or a 3:1 safety factor atoperating pressure differentials.

II. Modulating Steam PressureA. F&T traps and inverted bucket

traps with thermic buckets.

1.0-15 psig steam—2:1 at.5 psi pressure differential.(On F&T traps SHEMAratings can also be used.)

2.16-30 psig steam—2:1 at2 psi pressure differential.

3.Above 30 psig steam—3:1at 1/2 of maximum pressuredifferential across the trap.

B. Inverted bucket traps withoutthermic buckets. Above 30 psigsteam pressure only—3:1 at .5of maximum pressure differentialacross the trap.

5

4. Bimetallic and wafer traps—good.5. Not recommended for low pressure operations.6. Cast iron traps not recommended.7. In welded stainless steel construction—medium.

1. Condensate drainage is continuous, dischargeis intermittent.

2. Can be continuous on low load.3. Excellent when “secondary steam” is utilized.

8. Can fail closed due to dirt.9. Can fail either open or closed depending

upon the design of the bellows.

The Inverted Bucket Steam Trap

Venting of Air and CO 2The Armstrong inverted bucketprovides continuous automatic airand CO2 venting with no coolinglag or threat of air binding.

Operation Against Back PressureThe Armstrong inverted bucket hasexcellent performance against backpressure. It has no adverse effecton inverted bucket operation otherthan to reduce its capacity by thelow differential. The bucket simplyrequires less force to pull the valveopen and cycle the trap.

Freedom From Dirt ProblemsArmstrong designed its invertedbucket to be virtually free of dirtproblems. The valve and seat areat the top of the trap, far away fromthe larger particles of dirt which fallto the bottom. Here the up-and-downaction of the bucket pulverizes them.Since the valve of an inverted bucketis either fully closed or open, dirtparticles pass freely. And the swiftflow of condensate from under thebucket’s edge creates a uniqueself-scrubbing action that sweepsdirt out of the trap.

Energy Efficient BecauseIt’s So ReliableThe inverted bucket is the mostreliable steam trap operating prin-ciple known. The heart of its simpledesign is a unique leverage systemthat multiplies the force provided bythe bucket to open the valve againstpressure. Since the bucket is openat the bottom, it resists damage fromwater hammer, and wearing pointsare heavily reinforced for long life.

The inverted bucket has only twomoving parts—the valve leverassembly and the bucket. Thatmeans no fixed points, no compli-cated linkages. Nothing to stick,bind or clog.

Conserves Energy Evenin the Presence of WearArmstrong inverted bucket steam trapsopen and close based on the differ-ence in density between condensateand steam—the inverted bucketprinciple. They open and closegently, minimizing wear. Thissimple fact means that invertedbuckets are subject to less wearthan some other types of traps.

In fact, as an Armstrong invertedbucket trap wears, its tight sealactually improves. The ball valveand seat of the Armstrong trapprovide essentially line contact—resulting in a tight seal because theentire closing force is concentratedon one narrow seating ring.

An Armstrong inverted bucket trapcontinues to operate efficiently withuse. Gradual wear slightly in-creases the diameter of the ballvalve. But the more it wears, thetighter the seal. The ball valve seatsitself deeper as wear increases,preserving a tight seal.

Corrosion-Resistant PartsThe stainless steel valve and seatof the Armstrong inverted bucketsteam trap are individually groundand lapped together in matchedsets. All other working parts arewear- and corrosion-resistantstainless steel.

Inverted Bucket Traps

Virtually no steam lossSteam does not reach the

water-sealed discharge valve.

Resistance to damagefrom water hammer

Open bucket or float will not collapseas a result of water hammer.

Purging actionSnap opening of the valve

creates a momentarypressure drop and turbu-lence in the unit drained.

This breaks up films ofcondensate and air and

speeds their flow to the trap.

Dependable operationSimple, direct operation with

nothing to stick, bind or clog.Only two moving parts—thevalve lever and the bucket.

Freedom from dirt problemsCondensate flow under the bottom

edge of the bucket keeps sedimentand sludge in suspension until it is

discharged with the condensate.Valve orifice opens wide and closes

tightly. No buildup of dirt nor closeclearances to be affected by scale.

Continuous airand CO2 ventingVent in top of bucket providescontinuous automatic air andCO2 venting with no cooling lagor threat of air binding. Steampassing through vent is lessthan that required to compen-sate for radiation losses fromthe trap so it’s not wasted.

Excellent operationagainst back pressureSince trap operation is governedby the difference in density ofsteam and water, back pressure inthe return line has no effect on theability of the trap to open for con-densate and close against steam.

List of Materials NOTES:1. Maximum operating pressure to be marked onnameplate will be determined by actual orifice used.2. Maximum allowable pressures shown in boldfacewill be marked on nameplate, unless otherwiserequested. Traps with flanges may have differentpressure-temperature ratings.

Operation on superheat. A normallyoperating bucket trap is filled withsaturated steam and condensate.Superheated steam can enter onlyas fast as the steam inside cancondense. As a result, the temperatureof the trap is at (or slightly below)

saturated steam temperature,regardless of the degree of super-heat.

Trap selection. The pressure-containing parts of the steam trapshould safely withstand the maximum

pressure and temperature conditionsof the system. For example, a trap isrequired for a 1,000 psig main at950°F. The normal operating tem-perature of the trap will be about546°F. A Model 5133G trap shouldbe selected (see Table 10-2) even

though several smaller traps arecapable of handling the workingpressure.

For superheat service:1. Don’t oversize the orifice; a

restricted orifice may be advisable.2. Specify a burnished valve and

seat and also an extended inlettube and check valve.

3. Provide a drip leg ofadequate diameter andlength.

4. Provide a generous length(2-3 ft) of inlet piping, withthe trap below the main.

5. Don’t insulate the trap orthe inlet piping.

Inverted Bucket Capacity Chart

This catalog should be utilized as aguide for the installation and opera-tion of steam trapping equipment byexperienced personnel. Selection orinstallation should always be accom-panied by competent technicalassistance or advice. Armstrong andits local representatives are availablefor consultation and technical assis-tance. We encourage you to contactyour Armstrong representative forcomplete details.

To select an inverted bucket steamtrap using the Armstrong capacitychart, you must know the conden-sate load, safety factor and pressuredifferential. Remember, the objectiveis always to select a trap that can1) operate at the maximum differen-tial pressure and 2) handle the capacityat the minimum differential pressure.Consider the following typical problems.

EXAMPLE 1. Constant Pressure andCondensing RateGiven:Maximum pressure differential 70 psiOperating differential 60 psiCondensate load 300 lbs/hrtimes 3:1 safety factor or 900 lbs/hr

How to Use the Inverted Bucket Trap Capacity ChartEXAMPLE 2. Constant Pressure andCondensing Rate but with Possible HighBack PressureAssume for example:Maximum pressure differential 90 psiOperating differential minimum 40 psiOperating differential normally 60 psiCondensate load 300 lbs/hrtimes 3:1 safety factor or 900 lbs/hr

Note in Fig.13-1 that the 5/32" orifice will handlethe 900 lbs/hr load at a differential pressureof 60 psi. When the operating differentialdrops to the minimum level (40 psi),however, the capacity is only 800 lbs/hr.

To solve the problem, refer to the sawtoothchart. Enter at the minimum differentialpressure (40 psi) and move up until youintersect a line that is above 900 lbs/hrcapacity, which is the first thin blue lineabove the heavy blue “sawtooth” for the211, 811 and 881 traps. Note that this is thecontinuation of the capacity line for the 5/32"orifice for the 212, 812 and 882 traps. Nowfollow the line to the right until the verticaldrop at 125 psi differential. This is within ourrequirement of 90 psi. Therefore a 5/32" orificecan handle the 900 lbs/hr condensate loadwhen fitted into a 212, 812 or 882 trap andthat it will not lock shut at the 90 psi maxi-mum differential. This is the trap to use sinceit will handle the load at both the minimumand maximum operating differentials, eventhough it has a maximum operating pressuredifferential of 125 psi.

Enter chart at 60 psi line and go up to 900 lbs/hrcapacity. This is directly on the 5/32" orifice lineas shown in Fig.13-1. The capacity of this 5/32"

orifice at pressures less than 30 psi is indicatedby the thin blue line. Follow the line to theright to the vertical drop at 70 psi. This meansthis orifice will operate to a maximum of 70 psidifferential—the other requirement for thisapplication. Follow the heavy line back to theleft and note that it’s attached to the arrowindicating that the 211, 811 or 881 traps withthe 5/32" orifice will yield this capacity. This isthe trap to use.

will have a continuous dischargecapacity of a little less than 12,000lbs/hr at 40 psi.

Close study of this chart revealsthat steam trap capacity is governedby more than just the orifice diameter.A 2" No. 216 trap with 1/2" dischargeorifice, working at 15 psi pressure,has a continuous discharge capacityof some 7,200 lbs/hr, but a 3/4" No.213, also with 1/2" orifice and alsoworking at 15 psi pressure, has acontinuous discharge capacity ofonly 3,900 lbs/hr. In the case of theNo. 213, friction in the 3/4" pipe isgreatly restricting capacity, whereasthere is little capacity loss due topipe friction when a 1/2" orifice isused in a 2" pipe at 15 psi.

steam would be much too high. Orificetests also are too high because theyignore pipe friction. Theoreticalcalculations of trap capacities havenever been conservative. You candepend on Armstrong capacityratings because they show actualcapacities of hot condensate.

Heavy blue “sawtooth” curvesshow capacities for traps usingmaximum possible diameter orificesfor the pressures shown.

Thin line curves extending downto the left of the heavy curves showthe capacities of Armstrong trapsat pressures below their maximumratings. For example: A No. 216trap, with 1/2" orifice good for a max-imum working pressure of 125 psi,

How the CapacityChart Was MadeThe Armstrong capacity chart showscontinuous discharge capacities ofArmstrong traps under actual oper-ating conditions as determined byliterally hundreds of tests. In thesetests condensate at the steam temp-erature corresponding to the testpressure was used. The chokingeffect of flash steam through theorifice, as well as the back pressurecreated by flash steam, wereautomatically taken into account.Actual installation hookups wereused so that pipe friction in bothinlet and discharge lines also werereflected in the results.

A quick and easy “in-line” replace-ment for other types of side inlet/side outlet traps, the Series 1810brings together all the benefits ofenergy-efficient inverted bucketoperation. Side inlet/side outletconvenience plus lightweight con-struction mean an inverted buckettrap that will operate efficiently on

applications such as tracer lines,drips, heating, processing andsimilar applications. Choice of NPTor BSPT screwed connections, orsocketweld.

With the 1810 Series, you get all-stainless steel construction with itsthree-year guarantee. Plus all the

benefits of inverted bucket operation:■ A long, trouble-free service life■ Excellent purging action■ Continuous air venting■ And the ease and flexibility of

in-line installation

*NOTE: Because the orifice is located at the top,inverted bucket steam traps handle dirt and scalebetter than other types of traps. However, in app-lications where extremely dirty conditions exist,care should be exercised in the use of all types ofrestricted-orifice, reduced-capacity traps.

Series 1010 & U-1010 Stainless Steel TrapsFor pressures to 450 psig...capacities to 4,400 lbs/hr

The Series 1010 stainless steelinverted bucket steam trap normallylasts three to four times longer thanconventional traps used in identicalservices. Heat-treated stainlesssteel valves and seats are of thesame design, material and work-manship as those used in traps forpressures up to 900 psi and tem-peratures to 900°F. More compactthan cast iron or stainless steelequivalents, Series 1010 traps areideal for trapping applications suchas tracer lines, steam mains andheating/process applications.

All sizes are available with socketweldend connections or with standardNPT or British Standard pipe threads.

Condensate Operating Mechanism

Armstrong designed the automaticdifferential condensate controllers(DC) for applications where conden-sate must be lifted from a drainpoint or gravity drainage applica-tions where increased velocity willaid drainage. Lifting from the drainpoint (syphon drainage) causes areduction in pressure which flashesa portion of the condensate intosteam. Unable to differentiate

between flash steam and livesteam, ordinary steam traps closeand impede drainage.

Increased velocity with gravity drain-age will aid in drawing the condensateand air to the DC. This increasedvelocity is caused by an internalby-pass, controlled by a manualmetering valve, so the condensatecontroller will automatically vent

the by-pass or secondary steam.This is then directed to the conden-sate return line or collected for usein other heat exchangers.

Capacity considerations varygreatly with the application, but formost installations, a single DC willprovide sufficient capacity.

The Float & Thermostatic Steam Trap

Built As Tough As the JobsThey DoArmstrong float and thermostatictraps are unique in their super heavyduty construction. Armstrong useshigh quality ASTM A 48 Class 30cast iron—normally found in pressurevessels rated to 250 psi. Internalmechanisms are made from stainlesssteel and are heavily reinforced.No brass cotter pins here. Valvesand seats are stainless steel, hardened,ground and lapped to withstand theerosive forces of flashing condensate.

Why go to all this trouble on trapsnormally recommended for low-pressure, modulating service? Theanswer is in the word modulating.Modulating pressures mean widelyvarying loads, thermal cycling andhigh air and non-condensable gasloads. In other words, tough service.Inferior, lightweight construction is

The More Your Steam PressureVaries, the More You NeedArmstrong F&T TrapsWhen steam pressure may vary frommaximum steam supply pressure tovacuum, Armstrong F&Ts are yourmost energy-efficient choice. Ourline of F&Ts brings Armstrong per-formance, dependability and longlife to trapping services requiringcontinuous drainage with high airventing capacity. Thanks to separateorifices for condensate and air, theyprovide continuous condensatedrainage and air venting—evenunder conditions of zero pressure.

All the benefits detailed on the nextpage have been designed intoArmstrong F&Ts through long experi-ence in the manufacture of pressurefloat-type drain traps. They assureyou of optimum operating efficiencyfor long periods with minimum trouble.

a mistake waiting to happen. Trapfailures on modulating pressuremay lead to water hammer, corro-sion and even heat exchangerdamage.

Armstrong’s published capacities arebased on actual measurements oftraps handling hot, flashing conden-sate. Competitive F&Ts may utilizetheoretical calculated capacities.Armstrong uses its own steam lab togive you actual capacity—especiallyimportant on high-capacity traps suchas those in our ultra-capacity line.Not only does Armstrong offer superheavy duty construction for long lifeand reliability, but we also supply thedata to back up performance. Here’s asimple, easy-to-remember summary:The more your pressure varies, themore you need Armstrong F&Ts.

Corrosion resistanceEntire float mechanism ismade of stainless steel.The float is Heliarcwelded to avoid theintroduction of dissimilarmetals which could leadto galvanic corrosion andfloat failure.

No water seal at inletInlet high on body and con-densate discharge valve inthe bottom of the bodyprevent formation of a waterseal that could block flowof air to vent under verylow pressureconditions.

High-capacityventing of air and C02

Built-in thermostatic air ventdischarges large volumes

of air and C02 through itsseparate orifice—even

under very low pressureconditions.

Continuous drainageNo pressure fluctuationsdue to intermittentcondensate drainage.Condensate is dis-charged at very closeto steam temperature.No priming needed.

Operation against backpressure Trap operation isgoverned solely by thecondensate level in the trap.Back pressure in the returnline will not render the trapinoperative as long as thereis any pressure differential toforce condensate throughthe discharge valve.

Long life anddependable serviceValve is stainless steel inall sizes. Seat is heattreated in 11/2" pipe sizeand larger. Rugged floatmechanism is built toresist wear, and thestainless steel floatprovides exceptionallyhigh collapsing pressureand resistance tohydraulic shock.

*Capacities based on differential pressure with no back pressure.**Capacities will vary with the degree of subcooling. When greater capacities are required,the trap will automatically adjust to the load, up to the maximum (cold water) capacity shown,by increasing the amount of subcooling.

Thermostatic Wafer Traps

NOTE: Since the normal operation of all sup-pressed temperature-discharge (subcooling)steam traps is to back up condensate, theyshould not be used on drip legs for saturatedsteam service, heating or process equipment.Exercise care in the maintenance of anythermostatic wafer trap with a small dischargearea susceptible to clogging.

Capacities given are continuous discharge capacities in pounds of hotcondensate per hour at pressure differential indicated with condensatetemperatures approximately 25°F below steam temperatures.NOTE: CD traps can operate with a minimum of 2 psi inlet pressureand a maximum of 80% back pressure. However, for best results,inlet pressure should not drop below 10 psi and back pressureshould not exceed 50% of inlet pressure.

List of Materials

Armstrong Series CD-40 and CD-60controlled disc traps both contain areplaceable capsule, making it possibleto renew a worn trap by simply replac-ing the capsule. A heating chamberin the shell assures consistentoperation. This steam jacket provides

a relatively constant temperature inthe control chamber regardless ofambient conditions. Cycling rate iscontrolled and does not increasewhen the trap is exposed to coldwinds, rain or snow.

Series CD-60 traps contain integralstrainers with ratios of open area toinside area of pipe that equal orexceed those of most separate “Y”type strainers.
