Nickel Alloy Pipe Specification – ASTM B673

Overview:

B673 incorperates UNS N08925, UNS 8354, and UNS N08926 welded pipes with specific dimensions for general corrosion applications. Pipes will be produced from flat rolled materials and be automatically welded without the use of filler metal. There are two classes: Class 1 and Class 2. 

This specification covers UNS N08925, UNS N08354, and UNS N08926 welded pipe for general corrosion applications.

his specification covers pipe sizes in schedules shown in Table 1.

TABLE 1 Dimensions of Welded Pipe

Note 1—The following table is a partial reprint of Table 1 of ANSI B36.19.

Note 2—The decimal thicknesses listed for the respective pipe sizes represent their nominal wall dimensions.

Note 3—1 in. = 25.4 mm.
