ASTM A358 is a specification for electric-fusion-welded austenitic stainless steel pipe that performs well in high temperature industrial applications.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.
TONG CHUANG GROUP deal with stainless steel welded pipe and tube already more than 10 years， every year sell more than 5000 tons of stainless steel pipe and tube. Our client already cover more than 45 countries. Our Stainless Steel and tube was width used in Mining， Energy， Petrochemical，Chemical Industry， Food plant， Paper plant， Gas and Fluid Industry etc.
This specification covers Five classes of pipe 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.
