ASTM A691/A691M-09

Standard Specification for Carbon and Alloy Steel Pipe, Electric-Fusion-Welded for High-Pressure Service at High Temperatures

ABSTRACT
This specification covers carbon and alloy steel pipe, electric-fusion-welded with filler metal added, fabricated from pressure-vessel-quality plate of several analyses and strength levels and suitable for high-pressure service at high temperatures. Heat treatment may or may not be required to attain the desired mechanical properties. The pipes are classified according to steel grades and are designated in classes according to the type of heat treatment performed in the pipe manufacture, whether the weld is radiographically examined, and whether the pipe has been pressure tested. The steel welds shall be made either manually or automatically by an electric process involving the deposition of filler metal. The welded joints shall have positive reinforcement at the center of each side of the weld. The contour of this reinforcement shall be smooth, and the deposited metal shall be fused smoothly and uniformly into the plate surface. The joints shall undergo tension, bend and pressure tests. Unacceptable surface imperfections shall be removed by grinding or machining. The depression after grinding or machining shall be blended uniformly into the surrounding surface. Repair of weld and base metal defects shall be done by welding.
SCOPE
1.1 This specification covers carbon and alloy steel pipe, electric-fusion-welded with filler metal added, fabricated from pressure-vessel-quality plate of several analyses and strength levels and suitable for high-pressure service at high temperatures. Heat treatment may or may not be required to attain the desired mechanical properties or to comply with applicable code requirements. Supplementary requirements are provided for use when additional testing or examination is desired.  
1.2 The specification nominally covers pipe 16 in. [400 mm] in outside diameter and larger with wall thicknesses up to 3 in. [75 mm] inclusive. Pipe having other dimensions may be furnished provided it complies with all other requirements of this specification.  
1.3 Several grades and classes of pipe are provided.  
1.3.1 Grade designates the type of plate used as listed in Table 1.  
1.3.2 Class designates the type of heat treatment performed in the manufacture of the pipe, whether the weld is radiographically examined, and whether the pipe has been pressure tested as listed in 1.3.3.

This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
