(3) Working pressure based on an allowable fiber stress of MOO pei (for 250 F). (3) Working pressure based on an allowable fiber stress of 12000 psi (for 3S0 F). Note: Standard-weight pipe b generally furnished with threaded ends in random lengths of 15 to 33 ft., although when ordered with plain ends, 5 percent may be in Irff**"* of 12 to 13 ft. Five percent of the total number of lengths ordered may be jointers which ar* two pieces coupled together. Extra-etrong pipe b generally furwut--4 with pll" ends in random lengths of IS to 22 ft, although 5 percent may be in lengths of 8 to IS ft listed in Table 3 is the formula for allowable working pressures as given in the American Standard Code for Pres sure Piping.1 In this formula is a factor c, which is intended as an allowance for corrosion, mechanical injury, manufac turing tolerances, etc. At times this factor seems too con servative; for example, with Ys-isi., Schedule 40, steel pipe, the allowable working pressure is 314 pm. Yet this pipe is tested at 700 psi. The reasoning in establishing the factor c which influences the working pressure, is that after nominal use the pipe may not be as sturdy as it was at the time of manufacture. Note that the joint factor, c, is not included for plain end non-ferrous pipe as listed in Table 2. In addition to IPS copper pipe, several varieties of copper tuhiDg are in use with either flared or compression couplings or soldered joints. Dimensions of copper water tube intended for plumbing, underground water service, fuel-oil lines, gas lines, etc., have been standardised by the U. S- Government and the American Society for Testing Materials. Copper tube is classified in accordance with the wall thick ness as follows: Type K--Heavy Wall. Type L--Medium Wall.. Type M--light Wall. Type DWV--Light Wall--for drainage, waste, and vent service. In general, Type K is used for underground services and for general plumbing service where corrosion conditions are severe. Type L is used for general plumbing and-heating service where conditions may be considered normal. Type M is used for sanitary drainage and other non-pressure ap- _ plications, for heating, and sometimes for other services less severe than those for which Types K or L are recommended. Type DWV is of lighter weight than Type M, and is used for sanitary drainage and other non-pressure applications. Type DWV tube should not be used underground. Type L is suitable for underground drainage applications. Unless adequately protected, no copper tube should be embedded in a cinder fill. Where flexibility is essential as in hidden, re placement work, or where as few joints as possible are de sired as in fuel-oil lines, the soft temper is commonly used. In new or exposed work copper tube of a hard temper is generally used. All three types are extensively used with soldered fittings. Standard dimensions, weights, and diameter and wall- thickness tolerances for these classes of copper tube are ob tainable from Table 2. Copper pipe is *lsn available with dimensions of steel pipe. In refrigeration lines, used in connection with air-condi tioning equipment, copper tube is used extensively. For re frigeration use where tube absolutely free from scale and dirt is required, bright annealed copper tube that has been cleaned, dehydrated, and sealed is used. This tube is avail able in a variety of sizes and wall thicknesses. THREADING PRACTICE In all threaded pipe for heating and ventilating installa tions the American Standard taper pipe thread, ASA B2.11945 is used. This thread is cut with a taper of 1 in 16 measured on the diameter of the pipe so as to secure a tight joint. The number of threads per inch varies with the pipe size. Threads for fittings are the same, except that it is regular practice to furnish straight tapped couplings for Schedule 40 pipe 2 in. and smaller. For steam pressures in excess of 25 psi, it is recommended that taper-tapped couplings be used to obtain a tight joint. These may be secured by ordering line pipe* which is used for oil piping, the .couplings of which are provided with taper-tapped threads and may be used with regular mill-threaded standard weight pipe. Thread lengths should be in accordance with ASA B2.I. Right-hand threads are used unless otherwise ordered. To facilitate drainage, some elbows have the thread tapped at an angle to provide a pitch of the connecting pipe of y* in. to the foot. These elbows are known to the trade as
