1.0 GENERAL 1.1 DRAWING INDEXES Drawing indexes for the full range of Type 1648 seals can be found on PDM by performing a GENERAL search and typing T-1648* into the name field. HISTORICAL BACKGROUND: SEAL ORIGIN - TYPE 48 SERIES The T1648 seal evolved from the T48 seal family (T48LP/ MP/ HP) that was specifically designed for light hydrocarbon services. The T48 series design is originally a development of the type 8B1 seal. With the introduction of American Petroleum Institute (API) Seals Standard 682/ ISO 21049, the T48 seal line was designated as JC standard for general hydrocarbon processing applications including Non-hydrocarbons (water, limited acids, caustic and other crystallizing liquids), Non-Flashing Hydrocarbons, and Flashing Hydrocarbons. The T48 seals have been the preferred choice for safe, reliable, single and dual unpressurised and pressurised seal arrangements in petroleum services for many years. These reliable, engineered mechanical seals have been developed specifically to attain Maximum Achievable Control Technology (MACT) compliance in hydrocarbons and other Volatile Organic Compounds (VOC). These seals will control process emissions to less than 500 ppm. For detailed information on T48 Series Seals, see the latest issue of TPM 006 entitled ’John Crane Type 48 Series Seals’, which can be found on the EAA Engineering Intranet. 1.2 SEAL DESCRIPTION, DESIGN FEATURES & BENEFITS

SEAL DESCRIPTION The T48 seals are optimised for three pressure categories by the use of any one of three standard Primary Ring designs. The three standard seal design versions are the T48 LP, (Low Pressure) seal, the T48 MP (Moderate Pressure) seal and the T48 HP (High Pressure) seal.

T1648 Seal three standard Primary Ring designs Combinations of these seals allow for single type 1648, dual unpressurised (tandem) type 2648, and dual pressurised (double) type 3648 seal arrangements. The T48 seals can also be utilised in conjunction with a variety of containment seals. TYPE 1648 SINGLE SEAL CARTRIDGE The T1648 is an API 682/ ISO 21049 Type A, Arrangement 1, Single seal cartridge using one of three standard seal units; T48LP, T48MP, or T48HP. This Type A single seal is the primary default selection on which John Crane API 682/ ISO 21049 offering is based. T1648 seal is a multi-spring, Pusher o-ring, hydraulically balanced cartridge seal designed for lower, moderate and high-pressure applications. This single cartridge seal is designed to provide low emissions and low leakage for most refinery applications. It is applied in Non-Hydrocarbon, Non-Flashing Hydrocarbon, and Flashing Hydrocarbon services. It is also available in a stationary seal version.

DESIGN BENEFITS

• Low emission

Designed to satisfy U.S.A federal, state, and local regulatory requirements, the T1648 single seal provides effective sealing with emission control (less than 500 ppm (part per million) - EPA Method 21) for Volatile Organic Compound (VOC) services. The leakage containment device supplied as a default is a solid Carbon Floating Bushing; it is also available with a Fixed or Segmented Carbon Bushing.

• Application specific, flexible design

T1648 Seals are application specific with the proper selection of Primary Ring and Mating Ring materials. For higher duty applications, the T48HP uses special hydro-padded face geometry. Tighter tolerances, smoother sliding surfaces and no Anti-extrusion ring reduce secondary seal drag.

• Computer optimised seal face design

Computer modeling minimises distortion. Each seal has the built-in capability to offset the combined effects of pressure distortion, thermal distortion, and heat generation on leakage and wear.

• Optimised materials

For optimal performance, the seal face materials are specified Antimony filled Carbon Graphite versus reaction bonded Silicon Carbide, as standard.

• Maximum cooling

Distributed Flush is supplied as standard.

* API 682 TEST QUALIFICATIONS All arrangements of John Crane’s API 682 / ISO 21049 Type A seals have been qualification tested on propane in accordance with API 682/ ISO 21049 protocol for flashing hydrocarbon services. Additionally the Type 1648 has been qualification tested on water, qualifying it for non-hydrocarbon services. As required, the test includes a minimum of a 100-hour steady state, 4-hour static, and cyclic portion. During the cyclic portion, the process liquid is flashed to vapour a minimum of 5 times. Further, a 50 mm (2 inch) and 100 mm (4 inch) seal of each arrangement is tested. Emissions during the flashing hydrocarbon test are measured in accordance with Environmental Protection Agency (EPA) Method 21. John Crane’s testing facilities include the ability to test propane, cold oil, hot oil, water, and caustic.

3.0 SEAL PERFORMANCE & LIMITS 3.1 DYNAMIC PERFORMANCE The T1648 LP/ MP/ HP seals are rated for both light hydrocarbon and lubricating fluids. The pressure limits were developed based on an evaluation of important criteria, some of which are listed below:

• O-Ring extrusion • Antimony Carbon* vs. Reaction Bonded SiC face materials • Three year (extrapolated) seal life • For light hydrocarbons the seal chamber pressure is a minimum of 3.5 bar (50 psi) above the fluid vapour pressure at pumping temperature

* A Tungsten Carbide (optional material) Primary Ring is unsuitable for use on high Vapour Pressure (VP) services. An Engineering review is required to check that all potential of un-lubricated function of the seal face is eliminated. 3.2 DYNAMIC SEALING PRESSURE RATING For the standard T1648 Cartridge with T48 HP seal head incorporating the ‘Hydropad’ Primary Ring design, the Dynamic Sealing Pressure Rating (DSPR) is up to a maximum of 69 bar g (1000 psig). Refer to EAA Engineering for applications above the pressure limit specified.

EXAMPLES FOR DETERMINING PRESSURE RATING LIMITS EXAMPLE 1 Seal type: Type 48LP, Size: 75mm (3" diameter) Product: Lube Oil Speed: 3600 rpm Temperature: 82°C (180°F) Step 1 Determine the Pressure Limit for the given seal size, at the given operational speed, and for the process fluid: From the T48 LP Pressure Limits table, the pressure limit is 38.6 bar g Step 2 Determine the Pressure Multiplier Factors for this service condition: From the table of Multiplier Factors (above) apply the appropriate values, as follows

• For temperatures over 80°C, Pressure Multiplier Factor = 0.9. • For Lube Oil (Lubricating fluids), Pressure Multiplier Factor = 1.0.

Step3 Calculate the ‘adjusted’ maximum operating pressure: The maximum operating pressure = 38.6 bar g x 0.9 x 1.0 = 34.7 bar g EXAMPLE 2 Seal type: Type 48LP, Size: 75mm (3" diameter) Product: Water Speed: 3600 rpm Temperature: 82°C (180°F) Step 1 Determine the Pressure Limit for the given seal size, at the given operational speed, and for the process fluid: From the T48 LP Pressure Limits table, the pressure limit is 38.6 bar g Step 2 Determine the Pressure Multiplier Factors for this service condition: From the table of Multiplier Factors (above) apply the appropriate values, as follows

• For temperatures over 80°C, Pressure Multiplier Factor = 0.9. • For Water (Aqueous Solutions), Pressure Multiplier Factor = 0.75

Step3 Calculate the ‘adjusted’ maximum operating pressure: The maximum operating pressure = 38.6 bar g x 0.9 x 0.75 = 26 bar g

Note A Tungsten Carbide Primary Ring is unsuitable for use on high Vapour Pressure (VP) services. An Engineering review is required to check that all potential of un-lubricated function of the seal face is eliminated. 3.4 STATIC SEALING PRESSURE RATING The maximum Static Sealing Pressure Rating (SSPR) of the T1648 seal is the pressure limit of the axial retention of the setscrews in the drive collar, or the SSPR in the seal head, whichever is the lower. To calculate the axial retention limit of the setscrews, refer to the latest issue of EDS 0045 for guidance on performing sleeve retention calculations, and EDS 0102 for the setscrews material axial holding power data. Both documents are available on the EAA Engineering Intranet. To determine the maximum Static Sealing Pressure Rating (SSPR), consider both values of

• The Hydrostatic Sealing Pressure ÷1.5 • The Maximum Dynamic Sealing Pressure

The maximum Static Sealing Pressure Rating (SSPR) of the seal head is the greater of the two values. 3.5 REVERSE PRESSURE/ VACUUM OPERATION The single T1648 seal is unsuitable for operating on full vacuum. For partial vacuum operation please consult EAA Engineering. 3.6 TEMPERATURE The temperature limits are: - 40 °C to 290 °C (- 40 °F to 550 °F) dependent on materials used. 3.7 SPEED The Type 1648 seal is designed to operate at speeds not to exceed 25 m/s (5000 fpm) and 3600 rpm when supplied as a rotating unit. For higher speed applications a stationary mounted unit should be used. Please consult EAA Engineering. 3.8 VISCOSITY The viscosity limits are generally as specified in the following table:

Please note when the fluid viscosity is greater than 3500 cSt, use a dual seal or refer to EAA Engineering. 3.9 LEAKAGE The leakage data is not readily available for this seal. If required, ‘JC Seals’ is the preferred method to calculate the leakage rates under the seals operating conditions. For guidance on how to use the computer program, please refer to Technical Bulletin TB - 062 - entitled ‘Using the Engineering Program ‘JC Seals’ to determine seal Heat Generated and Seal Leakage. Also refer to TB- 057 entitled ‘JC-Seals Update, Version 3.15’. Both the above-mentioned guidance documents can be found on the EAA Engineering Intranet at the following location: EAA / Engineering / Mechanical Seals / Software & Calculations Please note the leakage Rate for the T48HP seal is significantly higher than those of the T48LP &T48MP seals.

3.10 POWER CONSUMPTION / HEAT GENERATION The power consumption / heat generation data for this seal type is not readily available. ‘JC Seals’ is the preferred method to calculate the power consumption/ heat generation. Please see reference to ‘JC Seals’ in sub-section 3.8 on Leakage. 3.11 FLUSH REQUIREMENTS ‘JC Seals’ is the preferred method to calculate the seal flush requirements. Please see sub-section 3.8 for more information on ‘JC Seals’ software. Also refer to Technical Bulletin TB- 057 entitled ‘JC-Seals Update, Version 3.15’ for information on flush plans and flush flow rates. Alternatively, the flush flow rate can be calculated manually from the following equation. For flashing hydrocarbon services the fluid temperature rise should be limited to a 2.5 °C (5 °F) rise and for non-flashing services the temperature rise should normally be limited to an 8 °C (15 °F). SI (Metric) Units: Q = 60 H / (SG . Cp . T) Where; Q = Flow rate (l/min) H = Heat Load (kW) SG = Specific Gravity ( ) Cp = Specific Heat (kJ / kg °C) ∆ T = Temperature Rise = T flush out – T flush in (°C) Imperial Units: Q = H / (500 . SG . Cp . T) Where; Q = Flow rate (g/min) H = Heat Load (Btu / Hr) SG = Specific Gravity ( )

Cp = Specific Heat (Btu / lb °F) ∆T = Temperature Rise = T flush out – T flush in (°F) 3.12 BREAKOUT TORQUE This data is not readily available. ‘JC Seals’ is the preferred method to calculate a value for the Breakout Torque required to overcome the seal friction at start up. 3.13 DRY RUNNING The Type 1648 seal is not designed for dry running. 3.14 SOLIDS & POLYMERISING HANDLING The Type 1648 seal is not specifically designed to handle solids. However, the following is a general recommendation for applications involving solids:

• Up to 0.3 % by weight or 3000 ppmw (parts per million by weight) maximum for a 3 year life with Carbon vs Silicon

• Up to 3 % by weight or 30000 ppmw maximum with hard faces

• Above 3 % by weight or 30000 ppmw, use hard against hard combined with either Plan 32

or plan 23. This assumes the abrasive has a hardness greater than 5 Mohs. The above should be qualified by recommending dual seals or plan 32 for particle sizes less than 25 Microns. Please note that data on polymerising duties is currently unavailable. 3.15 HAZARDOUS DUTIES & HAZARDS ANALYSIS T-1648 seals are approved for use in ATEX Cat. 2 & 3 applications (see ATEX Declaration of Conformity single seals on EAA Engineering Intranet)

3.16 AXIAL FLEXIBILITY AND MISALIGNMENT CAPABILITIES AXIAL MOVEMENT LIMITS The maximum allowable axial movement that the seal can safely handle is ±1.6 mm (± 0.062”). Please note this is not a setting tolerance. This is not normally a problem with overhung API pumps as there is limited axial movement due to bearing play and the fact that this seal is a true cartridge seal, not a hook sleeve mounted cartridge. It is of concern on between bearing pumps when the seal is run at higher temperatures as the non-thrust end can see considerable transient thermal expansion from start-up to running temperatures. The actual transient growth should be checked out to ensure that the seal does not exceed the above limits. This may require a special design or biasing the seal setting to allow for the temporary change in seal working height in certain applications.

ANGULAR & RADIAL MOVEMENT Excessive Run-out will have a detrimental effect on seal performance in the form of component wear or excessive leakage. For maximum reliability the setup of the pump should be within the limits published in API Standards 610 & 682/ ISO 21049, as follows:

• Concentricity of shaft to seal chamber: 125 µm (0.005”) Total Indicator Reading (TIR), sometimes also referred to as Full Indicator Movement (FIM).

• Squareness of seal chamber face to shaft not to exceed 15 µm per 3 cm of seal chamber bore (0.0005” per inch of seal chamber bore)

• Centering of the seal is to be by a register fit. The register fit surface shall be concentric

to the shaft and have a Total Indicator Reading (TIR) of not more than 125 µm (0.005").

• Run-out of sleeve outer diameter to inner diameter shall be less than 25 µm (0.001”) TIR 3.17 SEAL SUPPORT SYSTEM INFORMATION

• The T1648 Single Seal Cartridge is available with Axial Pumping Scroll when utilising API Flush Plan 23 (Type 1648-2/1648-3)
