PAGE 72 SPECIAL TRIMS AND TEMPERATURE RANGES AVAILABLE UPON REQUEST. TRIM CODE API SPEC, 6A RETAINED FLUID RATING TRIM TYPE T-21 AA STANDARD TRIM For essentially non corrosive liquids or gases. Typical are crude and reined oils, natural or refined gases and processed hydrocarbons. Typical uses are wellheads, manifolds, flowlines, and other similar installations requiring a through conduit valve. The temperature limitations are 0° to 250°F (-17.7°C to 121°C). T-22 BB STAINLESS TRIM For Substantially the same service as T-21 but where the corrosion resistance of 13% Chrome Stainless Steel internal parts are desirable. Also usable for mildly corrosive fluids and gases where limited corrosion of the internal body surfaces can be tolerated. The temperature limitations are 0° to 250°F (-17.7°C to 121°C). Recommended when partial pressure of CO2 is greater than 7.3. (Refer page 65) T-23 CC FULL STAINLESS STEEL TRIM For any liquid or gaseous product for which the resistance of the 13% Chrome Stainless is adequate. Also used where the resistance of Stainless Steel is desirable from the standpoint of product purity. The temperature limitations are 0° to 250°F (-17.7°C to 121°C). Recommended when partial pressure of CO2 is greater than 30. (Refer page 65). T-24 S-24 DD EE SOUR GAS & OIL Primarily for sour gas and oil where resistance to Hydrogen Sulfide embrittlement is required. Also suitable for other chemicals,products or hydrocarbons when H2S is present. May be used when CO2 is present in smaller amount then H2S. The temperature limitations are 0° to 250°F (-17.7°C to 121°C). T-26 FF STAINLESS SOUR GAS AND OIL TRIM Primarily for sour gas and oil when the CO2 exceeds the H2S content. It is intended to provide resistance to the metal loss type of corrosion usually associated with CO2, plus resistance to Hydrogen Sulfide embrittlement. The temperature limitations are 0° to 250°F (-17.7°C to 121°C). T-27 WATERFLOOD (UNINHIBITED) Primarily for use in untreated or uninhibited brackish saline water typically associated with oilfield waterflood projects and/or disposal wells in which the internal plastic coating of the body surfaces provides resistance to salt water corrosion.The internal parts are also resistant to Sulfide embrittlement and corrosion. The temperature limitation are 0° to 250°F (-17.7°C to 121°C). T-36 AA LOW TEMPERATURE - STANDARD TRIM - GENERAL OILFIELD For essentially non-corrosive liquids or gases. Typical examples are crude and refined oils,natural or refined gases and processed hydrocarbons. Typical uses are wellheads,manifolds,flowlines and other similar installations requiring a through conduit valve. The temperature limitations are -50° to 180° F. (-45°C to 82°C). T-37 S-37 DD EE LOW TEMPERATURE - SOUR GAS AND OIL Primarily for sour gas and oil where resistance to Hydrogen Sulfide embrittlement is required. Also suitable for other chemicals,products or hydrocarbons when H2S is present. May be used when CO2 is present in smaller amounts than H2S. The temperature limitations are -50° to 180° F (-45°C to 82°C) API6A TRIM TYPES 11 VALVE & CHOKE SPECIFICATIONS
