This specification covers electric-fusion-welded steel pipe suitable for corrosive service.

1.1This specification covers electric-fusion-welded steel pipe suitable for corrosive service.

Note 1:The dimensionless designator NPS (nominal pipe size) has been substituted in this specification for traditional terms such as nominal diameter, size, and nominal size.

1.2This specification covers grades of ferritic/austenitic steel as indicated in Table 1. The selection of the proper alloy and requirements for heat treatment shall be at the discretion of the purchaser, dependent on the service conditions to be encountered.

(A)Except as indicated, common name, not a trademark, widely used, not associated with any one producer.
(B)An AWS standard filler metal is not yet available for inclusion in this table.
(C)A grade designation originally assigned by the American Iron and Steel Institute (AISI).

1.3Five classes of pipe are covered as follows:

1.3.1Class 1—Pipe shall be double welded by processes using filler metal in all passes and shall be radiographed completely.

1.3.2Class 2—Pipe shall be double welded by processes using filler metal in all passes. No radiograph is required.

1.3.3Class 3—Pipe shall be single welded by processes using filler metal in all passes and shall be radiographed completely.

1.3.4Class 4—Same as Class 3, except that the weld pass exposed to the inside pipe surface is permitted to be made without the addition of filler metal (see 6.2.2.1 and 6.2.2.2).

1.3.5Class 5—Pipe shall be double welded by processes using filler metal in all passes and shall be spot radiographed.

1.4Supplementary requirements covering provisions ranging from additional testing to formalized procedures for manufacturing practice are provided. Supplementary Requirements S1 through S4 are included as options to be specified in the purchase order when desired.

1.5The 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 the specification is specified in the order.
