ASTM A213 Standard Scope
1.1 This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes, designated Grades T91, TP304, etc. These steels are listed in Tables 1 and 2.
1.2 Grades containing the letter, H, in their designation, have requirements different from those of similar grades not containing the letter, H. These different requirements provide higher creep-rupture strength than normally achievable in similar grades without these different requirements.
1.3 The tubing sizes and thicknesses usually furnished to this specification are 1/8 in. [3.2 mm] in inside diameter to 5 in. [127 mm] in outside diameter and 0.015 to 0.500 in. [0.4 to 12.7 mm], inclusive, in minimum wall thickness or, if specified in the order, average wall thickness. Tubing having other diameters may be furnished, provided such tubes comply with all other requirements of this specification.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.
TABLE 1 Chemical Composition Limits, %A, for Low Alloy SteelA Maximum, unless range or minimum is indicated. Where ellipses (…) appear in this table, there is no requirement, and analysis for the element need not be determined or reported.
B It is permissible to order T2 and T12 with a sulfur content of 0.045 max. See 16.3.
C Alternatively, in lieu of this ratio minimum, the material shall have a minimum hardness of 275 HV in the hardened condition, defined as after austenitizing and cooling to room temperature but prior to tempering. Hardness testing shall be performed at mid-thickness of the product. Hardness test frequency shall be two samples of product per heat treatment lot and the hardness testing results shall be reported on the material test report.

<p>Sunny Steel Enterprise Ltd., with strong support of our customers from around the world, we are a professional supplier in steel pipe and pipe fitting.
We provide our customer with mainly as below:
The Steel pipe include:
carbon steel seamless tube,stainless seamless tube, alloy seamless tube,seamless pipe, ERW pipe, SSAW pipe, UOE pipe and ceramic lined pipe.
The fittings include bend pipe, flange, cap, tees and cross, elbow, concentric reducer, valve etc.Quality ControlWhilst providing a quality, trusted service, we also place a high premium on quality craftsmanship. Our steel products are long-lasting, and always meet our clients exact specifications.The purpose of this section is to display the general parameters and guidelines for the quality control of products manufactured on a day to day basis at the manufacturing facilities of Sunny Steel.It is the intent of Sunny Steel to furnish products of the highest quality, using the best materials and workmanship available. All personnel involved in the quality control process, whether they are the location manager, or their designee, will conduct themselves in a professional manner, with the best interests of Sunny Steel Enterprise, and the customer in mind.Testing:Our range of steel pipe testing equipment is among the most expansive in the seamless tube manufacturing industry. This equipment is essential for testing both the chemical and physical properties of each seamless pipe and the material used to make it. It also allows us to detect hidden steel tube defects, ensuring the pipe quality. Listed below is our primary range of testing equipment currently in operation.1. Eddy current flaw detector2. Ultrasonic flaw detector3. Optical spectrum analyzer4. Universal testing machine5. Tensile strength tester, impact tester, hydrostatic test equipment, length measuring and weighing instruments.Packing:Our packing can meet any needs of the customers.How to packing the seamless pipe:There are probably hundreds of different methods for packing a pipe, and most of them have merit, but there are two principles that are vital for any method to work prevent rusting and Sea transportation security.The Packing Works for Steel FlangesSteel flanges must be packed with seaworthy packing method then delivery to customers, usually the packing way include wooden box, wooden pallet, iron & steel cage, iron & steel pallet etc.The Rust Prevention for Steel FlangesThe normal rust prevention treatment for steel flanges include yellow (Golden) paint Coating, black paint coating or black phosphating treatment, varnish paint coating, varnish antirust oil coating, electro galvanizing coating (Cold), hot dip galvanizing coating etc.The Packing Works for Steel FlangesSteel flanges must be packed with seaworthy packing method then delivery to customers, usually the packing way include wooden box, wooden pallet, iron & steel cage, iron & steel pallet etc. Because of the normal wooden boxes or wooden pallets have to do fumigation treatment, we usually use plywood pallet or plywood case or box to pack steel flanges without fumigation treatment. Whatever plywood or iron & steel packing way, they must be seaworthy, strong, waterproof and easy for loading and unloading.Shipping mark stick to outside of package.How better packaging the abrasion resistant pipeThere are probably hundreds of different methods for packing a abrasion resistant pipe and Elbows, and most of them have merit, but there are two principles that are vital for any method to work prevent rusting and Sea transportation security.Standard:Our highly-skilled manpower is dedicated to producing the finest quality steel pipe, pipe fittings, meeting a wide variety of material specifications. Their knowledge and experience of metal properties, welding procedures and quality control have set the pace and standard expected by our customers world-wide.PIPES & TUBES:Dimensions from carbon steel pipes are defined in the ASME B36.10 standard, dimensions for stainless steel pipe are defined in the ASME B36.19 standard. The material qualities for these pipes are defined in the ASTM standards.ASTM A106 = This specification covers carbon steel pipe for high-temperature service.ASTM A335 = This specification covers seamless ferritic alloy-steel pipe for high-temperature service. Grade: P5, P9, P11, P12, P22, P91, P92ASTM A333 = This specification covers wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures. Grade:Gr1, Gr3, Gr6ASTM A312 = Standard specification for seamless, straight-seam welded, and cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service.ASTM A213= Seamless Ferritic and Austentic Alloy Steel Boiler, Superheater and Heat-Exchanger Tubes, Grade:T5, T9, T11, T12, T22, T91ASTM A519= Seamless Carbon and Alloy Steel for Mechanical Tubing Grade:4130, 4130X, 4140FLANGES:Dimensions from carbon steel and stainless steel flanges are defined in the ASME B16.5 standard. The material qualities for these flanges are defined in the ASTM standards.ASTM A105 = This specification covers standards for forged carbon steel piping components, that is, flanges, fittings, Valves, and similar parts, for use in pressure systems at ambient and higher-temperature service conditions.ASTM A182 = This specification covers forged or rolled alloy and stainless steel pipe flanges, forged fittings, and Valves and parts for high-temperature service.ASTM A350 = This specification covers several grades of carbon and low alloy steel forged or ring-rolled flanges, forged fittings and Valves for low-temperature service.FITTINGSDimensions, from wrought carbon and alloy steel fittings are defined in several ASME standards. The material qualities for these fittings are defined in the ASTM standards.ASTM A234 = This specification covers wrought carbon steel and alloy steel fittings of seamless and welded construction.ASTM A420 = Standard specification for piping fittings of wrought carbon steel and alloy steel for low-temperature service.ASTM A403 = Standard specification for wrought austenitic stainless steel piping fittings.
