Product Description Product DescriptionThe ASTM A335 standard is a hallmark in the realm of alloy steel pipes, specifically engineered to excel in high-temperature and high-pressure environments. This prestigious standard, crafted meticulously by the American Society for Testing and Materials (ASTM), encompasses a range of rigorous testing methodologies. These include room temperature tensile testing, high-temperature tensile testing, high-temperature compression testing, and high-temperature bending testing, providing comprehensive insights into the material's performance and reliability under extreme conditions.Application AreaRenowned for its robustness, the ASTM A335 standard is integral to the design and manufacturing of pipeline equipment within high-temperature and high-pressure sectors, including petroleum, chemical, and power industries. By adhering to this standard's stringent testing protocols, manufacturers can guarantee that the alloy steel pipes possess the requisite strength and safety features necessary for reliable operation in high-temperature environments, thus ensuring durability and performance.Specific Products and Their UsesUnder the prestigious ASTM A335 standard, specific products such as P11 alloy seamless tubes stand out for their exceptional utility. These superior products are designed for critical applications, including heating surfaces, economizers, headers, superheaters, reheaters, and petrochemical industry pipes, particularly within high-pressure boilers. Their widespread adoption across industries such as petroleum, chemical, power, and aerospace underscores their indispensable role in supporting high-pressure boiler equipment. ASTM A213 steel pipes are mainly used for equipment such as boilers, superheaters, and heat exchangers, and are suitable for high-temperature and high-pressure working environments Specific Use: Boiler and Superheater: ASTM A213 steel pipes are suitable for boilers and superheaters, especially those components that need to withstand high temperature and high pressure environments. These steel pipes are commonly used for heating surface tubes, economizers, superheaters, and reheaters in high-pressure boilers (with working pressures generally above 9.8 MPa and working temperatures between 450 oC and 650 oC) Heat exchanger: ASTM A213 steel pipes are also used in heat exchangers, especially in environments that require high temperature and corrosion resistance. These steel pipes have good high temperature resistance and corrosion resistance, and can adapt to harsh working environments in heat exchangers The chemical composition and mechanical properties of ASTM A213 steel pipes make them excellent in high temperature and high pressure environments. Common grades such as T11, T12, T22, etc. have chemical compositions including elements such as carbon, silicon, manganese, as well as alloying elements such as chromium and molybdenum. These elements endow steel pipes with excellent high temperature resistance and corrosion resistance. For example, chromium element improves the oxidation resistance and corrosion resistance of steel pipes, while molybdenum element enhances their thermal strength Product application Detailed Photos Product ParametersASTM A335/A213 Chemical RequirementsGradeUNS Composition, % DesignationCMnPSSiCrMoP11/T11K115970.05-0.150.30-0.60 0.025 0.025 0.50-1.00 1.00-1.50 0.44-0.65 P12/T12K115620.05-0.150.30-0.61 0.025 0.025 0.50 max 0.80-1.25 0.44-0.65 P15K115780.05-0.150.30-0.60 0.025 0.025 1.15-1.65 --0.44-0.65 P21/T21K315450.05-0.150.30-0.60 0.025 0.025 0.50 max 2.65-3.35 0.80-1.06 P22/T22K215900.05-0.150.30-0.60 0.025 0.025 0.50 max 1.90-2.60 0.87-1.13 P23/T23K416500.04-0.100.10-0.60 0.030 max 0.010 max 0.50 max 1.90-2.60 0.05-0.30 P36/T36K210010.10-0.170.80-1.20 0.030 max 0.025 max 0.25-0.50 0.30 max 0.25-0.50 P91/T91K915600.08-0.120.30-0.60 0.020 0.010 0.20-0.50 8.00-9.50 0.85-1.05 P92/T92K924600.07-0.130.30-0.60 0.020 0.010 0.50 max 8.50-9.50 0.30-0.60 P122/T122K929300.07-0.140.70 max 0.020 0.010 0.50 max 10.00-11.50 0.25-0.60 P911/T911K910610.09-0.130.30-0.60 0.020 max 0.010 max 0.10-0.50 8.5-9.5 0.90-1.10 ASTM A335/A213 Tensile RequirementsGrade P1,P2P12P23P91P92,P911,P36 Class1P122P36 Class 2All OthersTensile strength,min:ksi[Mpa]55[380]60[415]74[510]85[585]90[620]90[620]95.5[660]60[415]Yield strength,min:ksi[Mpa]30[205]32[220]58[400]60[415]64[440]58[400]66.5[460]30[205]Hardness RequirementsGradeHardness. maxP91,P92,P122,P36250 HB/265 HV [25 HRC]Calculated Minimum Elongation ValuesWall ThicknessElongation in 2 in. or 50 mm, min, %All grades except P23, P36, P91, P92, P122, and P911P23, P91, P92, P122, and P911P36in.mmLongitudinaTransverseLongitudinaLongitudina5?16 (0.312)8302020159?32 (0.281)7.2281919141?4 (0.250)6.4271818137?32 (0.219)5.626--17123?16 (0.188)4.824--16115?32 (0.156)422--15101?8 (0.125)3.221--1493?32 (0.094)2.420--1381?16 (0.062)1.618--127Permissible Variations in Outside DiameterNPS [DN] DesignatorOverin.mmin.mm1?8 to1 1?2 [6 to 40], incl.1?64 (0.015)0.401?64 (0.015)0.40Over 1 1?2 to 4 [40 to 100], incl.1?32 (0.031)0.791?32 (0.031)0.79Over 4 to 8 [100 to 200], incl.1?16 (0.062)1.591?32 (0.031)0.79Over 8 to 12 [200 to 300], incl.3?32 (0.093)2.381?32 (0.031)0.79Permitted Variations in Wall ThicknessNPS [DN] DesignatorTolerance, % from SpecifiedOverUnder1?8 to 21?2 [6 to 65] incl., all t/D ratios20.012.5Above 21?2 [65], t/D ≤5 %22.512.5Above 21?2 [65], t/D > 5 %15.012.5Test Method Information for Certification and MarkingHydrostaticNondestructiveMarkingYESNOTest PressureNOYESNDENONONHYESYESTest Pressure/NDE Packaging & Shipping Company Profile Customer Visit FAQQ: Are you trading company or manufacturer?A: We are professional manufacturer for steel pipes,and our company also is a very professional and technical foreign trade company for steel products.
