Product Description Product DescriptionASTM A358 / ASME SA358 Stainless Steel EFW PipesASTM A358 / ASME SA358 Stainless Steel EFW PipesStandard Specification for Electric-Fusion-Welded Austenitic Chromium-Nickel Stainless Steel Pipe for High-Temperature Service and General ApplicationsASTM A358 Stainless Steel EFW Pipes specification covers electric-fusion-welded austenitic chromium-nickel stainless steel pipe suitable for corrosive or high-temperature service, or both, or for general applications.The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as "nominal diameter," "size," and "nominal size."This specification covers the grades of alloy and stainless steel listed in Table 1. The selection of the proper grade and requirements for heat treatment shall be at the discretion of the purchaser, dependent on the service conditions to be encountered.Five classes of pipe are covered as follows:ASTM A358 Class 1 - Pipe shall be double welded by processes employing filler metal in all passes and shall be completely radiographed.ASTM A358 Class 2 - Pipe shall be double welded by processes employing filler metal in all passes. No radiography is required.ASTM A358 Class 3 - Pipe shall be single welded by processes employing filler metal in all passes and shall be completely radiographed.ASTM A358 Class 4 - Same as Class 3 except that the weld pass exposed to the inside pipe surface may be made without the addition of filler metal (see 6.2.2.1 and 6.2.2.2).ASTM A358 Class 5 - Pipe shall be double welded by processes employing filler metal in all passes and shall be spot radiographed.Supplementary requirements covering provisions ranging from additional testing to formalized procedures for manufacturing practice are provided. Supplementary Requirements S1 through S6 are included as options to be specified when desired.The values stated in either inch-pound units or SI 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 nonconformance with the specification. The inch-pound units shall apply unless the "M" designation of this specification is specified in the order.304H stainless steel (UNS S30409) Grade 304 is the standard "18/8" stainless" it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans. for these applications it is common to use special "304DDQ" (Deep Drawing Quality) variants. Grade 304 is readily brake or roll formed into a variety of components for applications in the industrial, architectural, and transportation fields. Grade 304 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.Grade 304L, the low carbon version of 304, does not require post-weld annealing and so is extensively used in heavy gauge components (over about 6mm). Grade 304H with its higher carbon content finds application at elevated temperatures. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperaturesProduct ParametersProduct NameWeld Stainless Steel Pipes /TubesCompany Inform1.Name:WENZHOU GUOHAO STEEL., LTD 2.Type: Manufacturer MaterialAustentic / Duplex SteelDuplex : UNS S31803,UNS S32750, UNS S32760Austenitic :TP304, TP304L, TP304H, TP309S, TP310S, TP316L, TP316Ti, TP317L, TP321, TP321H, TP347H , 904L, 254SMOStandardASTM A312/A358/A778/A790 etcWelding Line TypeEFW / ERWSpecificationOuter diameter168mm-1828mmWall thickness3mm-30mmLengthSingle random length/ Double random length or as customer's actual requestSurfaceAnnealing&Pickling, Polishing180#-600#), Bright Annealing, Sand Blasting,Shot BlastingPackaging and Container LoadingFor Packaging and Container Loading, large-diameter pipe ports supported by wooden frames, the pipe end used cap or tape protection.
