Allowable pipe span is the maximum distance between supports or hangers that a pipe can span without excessive deflection or stress. It's an important parameter in piping design and engineering to ensure the structural integrity and safety of a piping system.

Pipe Support Span is defined as the optimum distance between two consecutive pipe supports to avoid excessive stress, sagging, bending, vibration, or failure of the piping or pipeline system in extreme cases.

Allowable spans are based on a maximum bending stress of 41.37 Mpa (6000 PSI) or a maximum deflection of 12.7 MM (0.5in). Hydrostatic testing: Spans are adequate without the addition of auxiliary supports for insulated lines and lines on shoes.

Proper pipe support span is as important as the selection of support. The distance between two consecutive support is defined as the support span. Supports are costly. Overdoing can impact your budget, and underdoing impacts plant safety. While deciding on proper pipe support spacing, the following shall be considered.

Jun 22, 2024 · The Allowable Pipe Span Calculator is an indispensable tool for engineers and technicians in the construction and maintenance of pipeline systems. This calculator helps determine the maximum distance between pipe supports, ensuring structural integrity and safety while minimizing costs and material use.

Calculate spacing between pipes on a pipe rack based on Dimensional Standard ASME B16.5 and B16.47. Pipe Outside Diameters as per ANSI ASME B36.10. Flange OD upto 24 inch as per ANSI ASME B16.5.

ASME has suggested the standards for support span, but the bending stress considered in its calculation is very low (15.9 Mpa). There are other references also who have listed the maximum support span. In this paper equations for calculating the maximum span using maximum bending stress are given.

Support span for PVC, Fiberglass and Steel pipes filled with cold water: Support centers for ABS, PE and PVC pipes - schedule 40 and 80: Pipe, tube and fittings sizes and dimensions. Inside and outside diameters, weights and more. Pressure ratings of ABS 1208, ABS 1210, ABS 1316 and ABS 2112. Dimensions of thermoplastic pressure pipes.

Pipe spacing refers to the specific distance maintained between adjacent pipes in a piping system. Proper spacing ensures that pipes do not interfere with each other during thermal expansion, maintenance, or operational movements. It also helps in avoiding mechanical damage and provides sufficient room for inspection and repairs.

Individual piping materials have independent considerations for span and placement of supports. Pipe size relates to the maximum allowable span between pipe supports. Span is a function of the weight that the supports must carry. As pipe size increases, the weight of the pipe also increases.
