MTC EN 10204 3.1 ,inspection and PMI pictures can be provided before shipment.People always confused about how to describe steel pipe dimensions (sizes) in correct ways, or how to clarify to seller what exactly pipe size we are going to purchase. How to order our ASTM A335 P11 Seamless Pipe/ASTM A335 P11 Pipes for oil refinery ? The type of test to be used shall be at the option of the manufacturer, unless otherwise specified in the purchase order. Hydrostatic or Nondestructive Electric Test-Each tube shall be subjected to the nondestructive electric test or the hydrostatic test.Flaring Test-One flaring test shall be made on specimens from each end of one finished tube, not the one used for the flattening test, from each lot.Flattening Test-One flattening test shall be made on specimens from each end of one finished tube, not the one used for the flaring test, from each lot.Subcritical Annealing or Tempering Temperature, Min or range ☏ įull or isothermal anneal normalize and temperĪSME SA335 P11 Pipes Tensile Requirements and Hardness: Mechanical properties ASME SA335 P11 Pipes Heat Treatment Requirements GradeĪustenitizing/ Solutioning Temperature, min or range ☏ *C – Carbon, Mn – Manganese, P – Phosphorous, S – Sulfur, Si – Silicon, Cr-Chromium, Mo – Molybdenum. 1.ASTM A335 P11 Pipes Chemical Composition Requirement P11 Pipe Chemical Components (%) Inspection and Test: Chemical Composition Inspection, Mechanical Properties Test(Tensile Strength,Yield Strength, Elongation, Flaring, Flattening, Bending, Hardness, Impact Test), Surface and Dimension Test,No-destructive Test, Hydrostatic Test. The different mechanical test requirements for pipes, namely, transverse or longitudinal tension test, flattening test, and hardness or bend test are presented. The range of pipe sizes that may be examined by each method shall be subjected to the limitations in the scope of the respective practices. Also, each pipe shall be examined by a non-destructive examination method in accordance to the required practices. Each length of pipe shall be subjected to the hydrostatic test. The steel material shall conform to chemical composition, tensile property, and hardness requirements. Grade P2 and P12 steel pipes shall be made by coarse-grain melting practice. The pipe shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Seamless Alloy Pipe Wall Thickness – Schedule 40 through XXH Length: Single Random Length, Double Random Length, 20 ft, 40 ft Ends Types: Plain, Beveled A335 Gr P11 seamless Pipe can be used as the starting material to produce A234 WP11 Pipe fittings,and match with A182 F11 flanges,and A182 F11 forged fittings.Ī335 P11 pipes are used in power generation and in downstream oil ,as well as refinery applicationĪ 335/A335M Standard Specification for Seamless Ferritic Alloy-Steel Pipe for High-Temperature Service The most commonly used P grades in the power generation industry and petro-chemical plants are P11, P22 & P91.ĪSTM A335 This specification covers seamless ferritic alloy-steel pipe for high-temperature service. P11 provides enhanced toughness, strength, hardness, and wear resistance often required in Power Plants, Space Craft, Nuclear Reactors, and Turbines.ĪSTM A335 P11 seamless pipe Specification.ġ/4” Nominal to 24”O.D. P11 as a listed material and provided the basic allowable stresses in tension at various temperatures.Ī335 P11 Pipe for High-Temperature and High-Pressure Service. The ASME B31.3 Code has designated ASTM A335 Gr. P11 seamless pipes, with nominal chemical composition of “1.25Cr-0.5Mo” or “1.25Cr-0.5Mo-Si”, can be used for ASME B31.3 process piping.
