containing up to & including 10% chromium. Pipe should be suitable for bending, flanging and similar forming operations and for fusion welding. Key Tests ­ Hydrostatic test, Non ­ destructive examination, transverse & longitudinal tension test, flattening test, hardness & bend test.

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. 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. Class 5 shall be double welded by processes employing filler metal and shall be spot radiographed. The finished pipes shall be subjected to transverse tension test, transverse guided-bend weld test, and hydrostatic test. Several grades & classes of pipes are provided. 8. ASTM A672 / A672M - 09 Grade refers to the type of plate used.
