See ASTM A-72. * American Society for Testing Materials Schedule. Thenumbers 30, 40, etc., refer to the ASTM Schedule; the letter (s) refers to the former designation Standard Weight', the letter (x) refers to the former designation Extra Strong; the letters XX refer to the former designation Double Extra Strong. * Weight per foot is based on plain end pipe. Threaded and coupled (T and C) pipe is slightly heavier. 4 Working pressure for welded joints--see formula in Table 3. (a) Working pressure based on an allowable fiber stress of 6225 pei (for 250 F). (b) Working pressure based on an allowable fiber stress of 8400 pei (for 250 F). (c) Working pressure based, on an allowable fiber stress of 12000 psi (for 250 F). Note: Standard-weight pipe is generally furnished with threaded ends in random lengths of 16 to 22 ft., although when ordered with plain ends, 5 percent may be in lengths,of 12 to 16 ft. Fivepercent of the total number of lengths ordered may be jointers which are two pieces coupled together. Extra-strong pipe is generally furnished with plain ends in random lengths of 12 to 22 ft;, although 5 percent may be in lengths of 6 to 12 ft. in. to 6 in., and in standard lengths of 5 or 6 ft, with external and internal diameters closely approximating those of extra strong wrought pipe. Castferrous pipe may be obtained coupled, beveled for welding, or with ends plain or grooved for the several types of couplings. It is easily cut and threaded as well as welded. The fact that it is readily welded enables tile manufacturers to supply the pipe in any lengths practicable for hand ling. AUoy Metal Pipe. Both iron and steel pipe are available in the alloy class. In the case of iron pipe when copper and molybdenum are added, the ma terial is known as alloy wrought-iron. By common custom steel is considered to be an alloy when the maximum range of alloying elements exceed certain limits such as 1.65 percent man ganese, 0.60 silicon, or 0.60 copper. Also, a steel is an alloy if any of the billowing elements are specified in minimal quantities or within limits: Al, tk C, Cb, Mo, Ni, Ti, W, V, Zr, or any other element added to obtain a certain alloying effect. Small quantities of. certain elements are present in alloy steels and are considered as incidental and may be present 10 the following maximum amounts: copper--0.35 percent, nickel--0.25 percent, chromium--0.20 percent, and molybdenum--0.06 percent.. Commercially, steel is considered stainless when chromium exceeds 3.99 Percent regardless of the inclusion of other alloying elements. With tvb- w. however, an alloy becomes stainless when it contains a minimum of *0.5 percent chromium , hlloy and stainless steels are used for high temperature piping and r highly corrosive fluids and gases. Copper Pipe and, Fittings. Owing to inherent resistance to corrosion,
