Specification for class II arc welding of carbon steel pipework for carrying fluids

PUBLISH DATE 1991

BSI BS 2971:1991

This British Standard specifies requirements for both shop and site class II arc welding of joints in carbon steel pipework intended to carry fluids. It covers manual, automatic or semi-automatic arc welding or combinations of these processes, but it also allows joints to be made with an oxy-acetylene root run without a backing ring by agreement between the contracting parties.

NOTE 1 For details of oxy-acetylene welding see BS 2640.

This standard is only applicable where there is adequate access available for welding and, when required, non-destructive testing.

NOTE 2 In cases of poor access, a mechanical connection could be used.

In addition to the definitive requirements, this standard also requires the items detailed in clause 2 to be documented. For compliance with this standard, both the definitive requirements and the documented items have to be satisfied.

NOTE 3 The titles of the publications referred to in this standard are listed on the inside back cover.

Welding using manual, automatic or semi-automatic processes. Welding consumables, preparation for welding, butt joints, branches, attachments, flanges, testing and inspection, acceptance requirements for optional non-destructive testing, procedure and welder approval tests.
