As a rule of thumb, the spacing of pipe supports for steel pipes in liquid service, expressed in feet, may be taken as the nominal pipe size, expressed in inches, plus ten. For example, the spacing of pipe supports on a 6 line will be approximately 6 + 10 = 16 feet. This spacing changes at high temperatures and for materials other than steel. For example, for copper tubing, support spacing varies from 8-ft for 1 tubing to 12-ft for 4.
Polypropylene pipe manufacturers recommend hangers. every 4â6â depending on the pipe diameter. â  Since glass pipe has a low coefficient of expansion, no expansion loops or. joints are needed. Its coefficient of expansion â 0.2â/100 ft/100Â°F â is. lower than any other drainline material. Polypropylene pipe needs. expansion joints and/or loops. â  The UL classified firewall penetration system is simple, easy to install. and effective.
