Five per cent 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 per cent may be in lengths of 6 to 12 ft. In addition to IPS copper pipe, several varieties of copper tubing are in use with either flared or compression couplings or soldered joints. Dimen- Table 2. Standard Weights and Dimensions of Welded and Seamless Steel Pipe3 aSizes larger than those shown in the table are measured by their outside diameter, such as 14 in. out* side diameter, etc. These larger sizes will be furnished with plain ends, unless otherwise specified. The weights will correspond to the manufacturers' published standards although it is possible to calculate the theoretical weights for any given size and wall thickness on the-basis of 1 cu in. of steel weighing 0.2S33 lb. bThe American Standard for Wrought-Iron and Wrought-Steel Pipe AS.A. B36.10-1939 has assigned no. schedule number to Double Extra-Strong pipe. A 10 in. Standard Weight pipe is also available with 0.279 in. wall thickness, but this wall is not covered by a Schedule Number. dOwing to a departure from the Standard-Weight and Extra-Strong wall thicknesses for the 12 in. nominal size. Schedules 40 and 00, Table 2 of the A.S.A. B36.10-1939, Standard for Wrought-Iron and WroughtSteel Pipe, the regular Standard and Extra-Strong wall thicknesses (0.375 in. and 0.500 in.) have been substituted. sions of copper water tubing intended for plumbing, underground water service, fuel-oil lines, gas lines, etc., have been standardized by the U. S. Government and the American Society for Testing Materials. There are three standard wall-thickness schedules of copper water tubing classified in accordance with their principal uses as follows: Type K--Designed for underground services and general plumbing service Type L--Designed for general plumbing purposes. Type M--Designed for use with soldered fittings only In general, Type K is used where corrosion conditions are severe, and Types L and M where such conditions may be considered normal- as, for 326' CHAPTER 17. PIPE, FITTINGS, WELDINC instance, in heating work. Types K and L are available in both hard and soft tempers; Type M is available only in hard temper. Where flexibility is essential as in hidden replacement work or where as few joints as possible '* 11 ------- /*Ammnnlu iicaH NiPW fir Table 3.

All three classes are extensively used with soldered fittings. Standard dimensions, weights, and diameter and wall-thickness tolerances for these classes of copper tubing are given in Table 3. Copper pipe is also available with dimensions of steel pipe. Refrigeration lines'used in connection with air conditioning equipment also employ copper tubing extensively. For refrigeration use where tubing absolutely free from scale and dirt is required, bright annealed. copper tubing that has been, deoxidized is used. This tubing is available in a. variety of sizes and wall thicknesses. 327
