Pipe support span chart is a tabular chart giving a rough idea of supporting distance.
Span pipe support spacing table standards.
The values does not apply where loads are concentrated with flanges valves specialties etc.
Spans or support spacing are based on maximum pipe deflections of 6 35 mm up to 6 and 12 7 mm for pipe sizes 8 and above.
Regardless of 1 cubic ft.
Provided the sag between supports remains acceptable.
3 pipe support span chart from mss sp 69 is reproduced as a sample.
Spans are based on 12 1 2 mill tolerance and 065 correction tolerance.

Add standard and customized parametric components like flange beams lumbers piping stairs and more.
Of water weighs 62 41 lbs.
It is based on a maximum bending stress of 2300 psi and maximum sag at mid span of 0 10.

Hanger support spacing rod sizes horizontal pipes recommended maximum support span between hangers and rod sizes for straight horizontal pipes.
If supports are spaced greater than 25 0 consultation with a structural engineer should be performed for additional analysis.
These charts are normally mentioned in piping stress analysis project specifications.
In practice longer spans are usually feasible with a deadweight bending stress in the order of 5000 psi to 10 000 psi.
Recommended maximum space between hangers for straight horizontal pipes and tubes are indicated in the table below.
Pipe support span chart.
Based on mss table 3 4 based on astm a53 86 many codes require pipe hangers to be spaced every 10 ft.
Spans are also provided for pipe deflection of 25 mm for all pipe sizes.
1 gallon u s weighs 8 335 lbs.
References values of maximum span for ss pipe 300 nps filled with water meters no.
Spans are based on using carbon steel pipe a53 gr b filled with water.
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.
Spans are based on insulated and uninsulated lines below 650 f.
Spacing and capacities are based on water filled pipe.

This is a classic spacing table for steel pipe.

A common rule of thumb is to support loads of this type with hangers on both sides of the load.
