Pipe Support Systems

Pipe support spacing depends on pipe diameter, material, and contents. ASME B31.1 provides maximum spans: 4-inch steel pipe supports every 10 feet, while 8-inch requires 13-foot spacing. Thermal expansion demands adjustable roller supports at calculated intervals. Vertical risers need guides every 15-20 feet plus anchors at direction changes. Incorrect spacing causes sagging, stress fractures, and premature joint failure.
