    Scope
    This specification covers steel pipe 16 inches in outside diameter or larger that is electric fusion welded (EFW) with filler metal added, fabricated from pressure vessel quality plate and suitable for high-pressure service at moderate temperatures. Several grades designate the type of plate used; classes designate the type of heat treatment performed during the manufacture of the pipe, whether the weld is radiographically examined, and if the pipe has been pressure tested.
    Chemical composition
    Product analysis of plate: The pipe manufacturer shall make an analysis of each mill heat of plate material. The product analysis shall meet the requirements of the plate specification to which the material was ordered.
    Product analysis of weld: The pipe manufacturer shall make an analysis of the finished deposited weld material from each 500 feet or fraction thereof. Analysis shall conform to the welding procedure for deposited weld metal.
    Heat treatment
    Classes 10, 11, 12 and 13 are not heat treated. All other classes must be heat treated according to the parameters shown below:
