ASTM A358 Standard for Electric-Fusion-Welded Austenitic Chromium-Nickel Stainless Steel Pipe for High-Temperature Service and General Applications. Covers electric-fusion-welded austenitic chromium-nickel stainless steel pipe suitable for corrosive or high temperature service, or both, or for general applications.
The pipes shall be sorted into five different classes. Class 1 pipes shall be double welded by processes employing filler metal in all passes and shall be completely radiographed. Pipes of Class 2 shall be double welded by processes employing filler metal in all passes with no radiography. Both Class 3 and Class 4 pipes shall be single welded except that the weld pass of the latter exposed to the inside pipe surface may be without the addition of filler metal.
Pipes of Class 5 shall be double welded by processes employing filler metal and shall be spot radiographed. Weld defects shall be repaired by removal to sound metal and rewelding. Subsequent heat treatment shall be as required on the original welds. The finished pipes shall be subjected to transverse tension test, transverse guided-bend weld test, and hydrostatic test.
This 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:
Class 1—Pipe shall be double welded by processes employing filler metal in all passes and shall be completely radiographed.
Class 2—Pipe shall be double welded by processes employing filler metal in all passes. No radiography is required.
Class 3—Pipe shall be single welded by processes employing filler metal in all passes and shall be completely radiographed.
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 .
Class 5—Pipe shall be double welded by processes employing filler metal in all passes and shall be spot radiographed.
ASTM A358 pipe comes under different standards such as ASTM, DIN, JIS, GB, AISI and other international standards. The ASTM A358 Class 1 EFW Pipes are made with electric fusion welding. The materials for the astm a358 tp304 has 18% chromium, 8% nickel and manganese, silicon, sulfur and phosphorus in the composition. The much higher resistant a358 316l contains molybdenum in the composition. The molybdenum content makes the material resistant to chloride ion corrosion. The a358 304 is the most used because of the strength and cost efficiency. The astm a358 stainless steel pipe comes in sizes ranging from 8 inches to 72 inches. The thickness of the pipes ranges from 3mm to 60mm. The astm a358 uns s31254 ranges in length up to 6 meters. ASTM A358 TP304L Stainless Steel EFW Pipes can come in different finishes such as pickled finished, BA finish, No 4 finish and electropolished. The astm a358 tp304 cl1 and class 2 have slight mechanical differences. The astm a358 tp304l class 1 is more commonly used material but the class 2 has higher mechanical properties and is used for unique applications.
ASTM A358 Grade TP316L Class 1 Stainless Steel EFW Pipe ERW Pipe is used in food and beverage industry, construction industry, nuclear applications, boilers, petroleum and petrochemical applications. The astm a358 tp316l cl1 can also come in different pressure classes that are categorized into schedules 10 through 160. Both the 304 and 316 materials come with their lower carbon versions. The lower carbon content allows for better welding capacities.
