what is the standard spacing distance of pipe support base
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.
