ABSTRACT

This report covers the results of an effort involving a threemonths period to retrieve information on the compat.bilityof wire cloth filters with rocket propellants. The same typesof wire cloth used in filters is also used in ;urface forceorientation devices in missile systems underc!,inq low gravityenvironment.

During this stud 96 filters were found that are consideredgood candidates for useful information. Each of these filter:swere found as part of an installation or as a separate unit.Most of the filters were still installed in live systems withpropellants and p~rforming their designated function. S.iO:of the filter ele ents have been borrowed, visually inspectedand photographed. Data sheets on all 96 units ha':e been pre-pared and are included in this report. Time histcries for thespecLments range from 7-1/2 years to 3 months.

INTRODUCT ION

Advances in the art of applying surface tunsion technologyto the management of liquid gas interfaces in Space Propul-sion Systems and Tactical Weapons and other related activitieshas raised questions as to the long term effects of highenergy propellants on fine micronic wire cloth from whichsuriace tension devices are made.

A materials storabiLity program is underway at the EdwardsAir Force Base Rocket Propulsion Laboratory and in years tocome, valid empirical storability data will be acquired.

In the interim, a means of gathering compatability data onwire cloth, is to research records of wire cloth filters thathave been made for use with these propellants, to trace theirwhereabouts and examine those that have been in extended usefor effects of propellants on the wire cloth.

This report summarizes the results of an effort covering athree month period to collect data that would provideevidence of the storability of stainless steel wire clothin high energy propellants. In retrieving data for thiscontract, four major test facilities were visited: TRWTest Site, San Juan Capistrano; Wyle Laboratorics, Nor-oFacility; Rocketdyne, Santa Susana Facility; and Marquardt

4 Corporation, Magic Mountain Test Site.

Five filter manufacturers are r, presented by twenly-thre,case histories established which represent ninet -six f Iters;

t Capitol Westward Filter Company, Pararount, Cal if.; Mir ro-porous Filter Company, Anaheim, Calif.; Flowr ,tics CorpanySacramento, Calif.; and Western Filtei Comp,, .y, Gard na, Calif.Although the contract called for a review t Wester, Filterrecords to determine candidate filters, - was rei-.ized thatit would be more effective to go into .t: field w ere there wasa good chance of finding some candida, es and det rrnine vitaldeisgn data. In followinq this proc dure, sevo al filterswere uncovered that were not manufactured by ýNostern Filter.However, since they were excellent examples 3r data, they havebeen documented and the resultant data is c closed in thisreport. Unfortunately, design data is not always tncludeddue to the prorubitive length daf time allnowed by the contract.

CASE HISTORIES AND DESCRIPTIONS

This section contains information and data retrieved duringaccomplishment of the study. Included are data sheets, photoreduced drawings of the filter assembly and filter element.and where possible, photographs of the general and specificareas where the filter units are located. Because of limitedaccess to the various test sites, photographs could not betaken of all units observed. In most cases, supervisory per-sonnel reviewed their files for photos taken of *-he area whichcontained a view of the filter.

In instances where filters were considered good arandidatesbut were not Western Filter units, it was not possible to getcopies of the drawings of the units. Consequently, in thetime allotted for this program, an attempt was mvade to gatheras much information as available. In some instdnces, photosof the units were available.

Photographs showing the surroundings indicate tA.e environmentalconditions, such as vibration from close proximity of enginetests, sunlight exposure causing hot day cyclint. conditionsas well as outdoor cold day conditions. Also. .,n indicationis given showing the ease or difficulty entailei in remo-inga sample element for further evaluation.

DESCRIPTION- CUR HISTORY #1

Filter Assembly P/N 1-1-10005 is a Y-Type configuration.The entire assembly is manufactured from stainless steel andHeli-arc welded in construction. This unit has 4-inch, 150lb., ASA inlet and outlet flanges. A feature of this configu-ration is that the filter element can be removed without havingto remove the filter case from the line. By removing theend cap and spider assembly, the element will slip out forcleaning or replacement. The pleated element is 304 stainlesssteel, Heli-arc welded and has in excess of 400 squ&re inchesof screen.

There are four filter units in this case history. Th,! unitshave been in use at Wyle Laboratories, Norco Facility, forneven years. They have been functioning exposed to direztsunlight and weather. Flow rates have been to 250 GPM isingboth UDMH and N2 04 alternately. The elements have been cleanedmany times.

Figures 2 through 10 relate information to the four candidateunits in this case history. We have visually inspected the fil-ter element shown and screen shows no dettimental effect fromlong term service.

The element in Figure 8 had the outer shroud removed. Theshroud was similar to the inner shroud shown. A polka dotpattern of discoloration is in evidence on the screen. Thismatches the outer support holes and is believed to be a de-posit caused by the higher concentration of fluid flow throughthis area.

To satisfy this theory, one-half of the unit was cleaned inan electro polishing bath. The polka dot pattern diminishedin this area as a result of the cleaning. Tne upper half ofthe element remains as found, for a basis rf comparison.See Figure 9. A close-up view of the element showing the ar*aas found and the area cleaned is shown ir Figure 10. In ob-serving the cleaned area, there appeared to be no deleteriouseffects on the wire cloth from prolonged exposure to the propel-lants.

Filter element P/N 412G was manufactured by Microporous FilterCompany, Anaheim, California. The filter is 100% stainlesssteel, heli-arc welded from 304 stainless steel, 2 micronicDutch Twilled wire cloth.

The filter has been in service for four years in the follow-ing propellants: 50/50 Hydrazine, NTO, IRFNA, UDMH. Thereis evidence that a filter in contact with a multitude of pro-pellants is exposed to more difficult environmental require-ments than u7ren in contact'with only one propellant. Thefilter has been used in the Ground Support Equipment for theGemini program.

The time span of this study did not allow retrieval of thedesign details. However, the element is pleated stainlesssteel screen and similar to Western Filter Company filterP/N 9-1-500 specifications for which are included in thisreport.

The fabrication of Western Filter Company filter assemblyP/N 321060 was to demonstrate the superior compatibility ofnickel as a filter media for use with Fluorine. Because of thedesire to reduce the number of unknowns the unit was made ofall nickel and a nickel seal was used. The compatibility ofthe nickel element was demonstrated, as is evidenced by thedata provided by the Douglas Company. However, some assemblyand disassembly difficulty was encountered due to the gallingof similar materials.

Although the unit was designed to perform a function of a fil-ter, the Douglas Company desired to conduct a bubble pointtest with a surface tension device in liquid Fluorine. A co-operative effort was established for Western Filter to provideDouglas a nickel surface tension device for the bubble pointtest and Douglas would conduct a compatibility test on the filterassembly. The filter element was used as the surface tensiondevice for the bubble point test (see Figure 46) and then testedas a filter (see Figure 45)

DESCRIPTION OF COMPATIBILITY TEST SET-UP P/N 20319

The test apparatus used is illustrated in Figure 46, consistsof a Kovar-Pyrex adapter made from a Kovar-lyrex glass metalseal, 1.25" OD.

The end of the 4" tube was bent 90° and reduced to 1/4" ODglass tube ( incheb long.

The adapter was , onnected with an AN fitting to the downstreamsid..• of the Western Filterassembly by flaring the Kovar tubeend. T,-h upstr.3am side of the filter is connected to a 1/2" lineGaseous nelium is introduced on the upstream side and measuredby a Heise precision pressure gauge. The downstream pressuregage was a compou-1 vacuum pressure type.

The -ilter test -issembly was fluorine cleaned by vagor degreasedin F.r-eon and baked dry (vacuum) for 24 hours at 105 C.

The test unit is assembled and then cooled in a Dewar to -320°F(see Figure 2).1F is condensed from scrubbed GF2 into the test unit. A slow

GHe sweep on the downstream side of the test unit is turnedon and passes out through a disposal line.

The upstream side of the test unit is pressurized with GHe.The GHe pressure is reduced until gas bubbling stops and thepressure is again recorded. The differences between thesetwo pressures is reported as the gas breakthrough pressure(see Table 1).

The level of LF2 during GHe pressurization was above the 6"sight level.

After the test, the LF was disposed, the filter was removedand examined for signihicant D ,-rosion attack. None was ob-served.

Based on the similarity between micronic filter elementsand surface force orientation devices and the 96 filterelements surveyed and inspected by Western Filter Company,the following may be concluded:qI1. Micronic stainless steel devices are compatible with

"storable oxidizers and fuels when in contact with thesepropellants for long periods of time.

2. Long term storaqe of stainless steel screen devices inN2 04 , CLF5 , CLF3 , and amine fuels does not cause degra-

dation in the surface tension chaiactcristics of thedevices.

3. Fine mesh screen devices must be thoroughly cleanedbefore being used with corrnsi-e ptrioellants in orderto insure no deterioration of t:c device. The deterior-ration of the filter element reported in Case History#17 was due to improper cleaniA-, which resulted indeterioration of the device when ised in IRFNA.

RECOIMENDAT IONS

A It is recommended that the Rocket PropulsionLaboratory advise all Air Force Contractors andGovernment Agencies utilizinq high energy propel-lant, or who have utilized such fluids in thepast, to inventory installation of Filters inuse, or on the active status, and to hold suchhardware and records for future evaluation.

B It is recommended that a Liaison team be estab-lished to visit those activities to review suchfilters or installation which would representvaluable candidate case histories.

C It is recommended that the case histiries be docu-mented and the candidate anits acquired.

D It is recommended that an organizatiorn with capa-bility to provide Testing Spectrographic Analy-sis and Documentation be given case historiesand units acquired for analysis

E It is recommended that results of recommendationsA through D be disseminated in reports to thetechnical commun ity.
