Pipe, Fittings, Welding 627 copper and red brass pipe have always been used in heating, ventilating, and water supply installations, but the cost with standard dimensions for threaded connections has been high: The introduction of fittings which permit erection by soldering or sweating, allows the use of tube with thinner walls than would be possible with threaded connections, thereby reducing the cost of installations. COMMERCIAL PIPE DIMENSIONS Commercial pipe dimensions are covered in the following specifications of the American Society for Testing Materials: (1) steel--ASTM A-120 and A-53, (2) wrought-iron--ASTM A-72, and (3) copper tube--ASTM A-88. Tables 1 and 2 are based on these specifications. In addition to the specifications for these three materials, there are Table 3.

Copies of the following specifications may be obtained from the American Society for Testing Materials: (1) steel, wrought-iron and cast-iron--Series A, (2) copper and red bra--Series B, and (3) clay and concrete--Series C.

Yet tins pipe is tested at 700 psi. The reason ing 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
