1 ADELAIDE BRISBANE PERTH API6A MATERIAL SERVICE CATEGORIES & RATING LEVELS OVERVIEW STANDARDS Austrlin Pipeline Vlve (APV) stndrds comply with technicl specifiction API-6A. The description for APV equipment consists of generl description, working, temperture rting mteril clss rting, product specifiction level (PSL) nd performnce requirement (PR). These rtings re defined in the following API-6A tles. To comply with API-6A (ISO 10423), APV offers: Pressure rtings in psi: 2000, 3000, 5000, 10,000 & 1. Temperture rtings: L, P, R, S, T, U, V, X & Y. Mteril clss:, BB, CC,,, FF & HH. Product specifiction level: 1, 2, 3 & 4 (PSL 1, 2, 3, 4). Performnce requirement: 1 & 2.

PSL (PRODUCT SPECIFICATION LEVEL) MATERIAL REQUIREMENTS PSL Mteril Control is found in API Specifiction 6A, Specifiction for Wellhed nd Christms Tree Equipment Section 400 PSL (PRODUCT SPECIFICATION LEVEL) QUALITY CONTROL PSL Mteril Control is found in API Specifiction 6A, Specifiction for Wellhed nd Christms Tree Equipment Section 400 PSL (PERFORMANCE REQUIREMENTS) LEVELS There re two Performnce Requirement Levels, PR1 nd PR2. The ltter represents more rigorous performnce requirements. See API Specifiction 6A, Section 300 nd Section 900. Section 905 covers vlves ( Flowline Vlves, Actuted Vlves).

4 TRIM CODE T-21 T-22 T-23 T-24 S-24 T-26 T-27 T-36 T-37 S-37 API SPEC, 6A RETAINED FLUID RATING BB CC FF STANDARD TRIM TRIM TYPE For essentilly non corrosive liquids or gses. Typicl re crude nd reined oils, nturl or refined gses nd processed hydrocrons. Typicl uses re wellheds, mnifolds flowlines, nd other similr instlltions requiring through conduit vlve. The temperture limittions re 0º 250ºF (-17.7ºC 121ºC). STAINLE TRIM For sustntilly the sme service s T-21 ut where the corrosion resistnce of 13% Chrome Stinless Steel internl prts re desirle. Also usle for mildly corrosive fluids nd gses where limited corrosion of the internl ody surfces cn e lerted. The temperture limittions re 0º 250ºF (-17ºC 121ºC). Recommended when prtil of CO2 is greter thn 7.3. FULL STAINLE STL TRIM For ny liquid or gseous product for which the resistnce of the 13% Chrome Stinless is dequte. Also used where the resistnce of Stinless Steel is desirle from the stndpoint of product purity. The temperture limittions re 0º 250ºF (-17.7ºC 121ºC). Recommended when prtil of CO2 is greter thn 30. SOUR GAS & OIL API6A TRIM TYPES Primrily for sour gs nd oil where resistnce Hydrogen Sulfide emrittlement is required. Also suitle for other chemicls, products or hydrocrons when H2S is present. My e used when CO2 is present in smller mount then H2S. The temperture limittions re 0º 250ºF (-17.7ºC 121ºC). STAINLE SOUR GAS AND OIL TRIM Primrily for sour gs nd oil when the CO2 exceeds the H2S content. It is intended provide resistnce the metl loss type of corrosion usully ssocited with CO2, plus resistnce Hydrogen Sulphide emrittlement. The temperture limittions re 0º 250ºF (-17.7ºC 121ºC). WATERFLOW (UNINHIBITED) Primrily for use in untreted or uninhiited rckish sline wter typiclly ssocited with oilfield wterflood projects nd/or disposl wells in which the internl plstic coting of the ody surfces provides resistnce slt wter corrosion. The internl prts re lso resistnt Sulfide emrittlement nd corrosion. The temperture limittion re 0º 250ºF (-17.7ºC 121ºC). LOW TEMPERATURE STANDARD TRIM GENERAL OILFIELD For essentilly non-corrosive liquids or gses. Typicl exmples re crude nd refined oils, nturl or refined gses nd processed hydrocrons. Typicl uses re wellheds, mnifolds, flowlines nd other similr instlltions requiring through conduit vlve. The temperture limittions re -50º 180ºF. (-45ºC 82ºC). LOW TEMPERATURE SOUR GAS AND OIL Primrily for sour gs nd oil where resistnce Hydrogen Sulphide emrittlement is required. Also suitle for other chemicls, products or hydrocrons where H2S is present. My e used when CO2 is present in smller mounts thn H2S. The temperture liittions re -50ºC 180º F (-45ºC 82ºC). SPECIAL TRIMS AND TEMPERATURE RANGES AVAILABLE UPON REQUEST.
