American Society of Heating and Ventilating Engineers Guide, 1930 to anchor and so to give freedom for expansion of the piping that no strain therefrom shall be allowed to distort the radiators. When expansion strains from the pipes are permitted to reach these light metal heaters they usually emit sounds of distress which are exceedingly troublesome. Standards Several. tables of-standard . dimensions of piping and fittings are appended. 125 Lb. Cast Iron Flanged Fittings Chapter 18--Pipe and Fittings Table 1 is for standard wrought pipe and Table 2 is for extra strong wrought pipe. . ' ;` Standard roughing-in dimensions for angle type valves are given in Table 3. The dimensions of elbows, tees and crosses for 125 lb. cast iron screwed fittings are given in Table 4, whereas the dimensions of tees and crosses for 125 lb. cast iron flange fittings are given in Table 5. Table 7 gives the dimensions of welding neck flanges for standard pipe. 125 Lb. Cast Iron Flanged Fittings TEE SIDE OUTLET CROSS Table 5.

The angle designation of an elbow is its deflection from straight line flow and is the angle between the flange faces. - dSide outlet elbows shall have all openings on interacting center-lines. 307
