Table 1 comparative values of span sr.
Span pipe support spacing table standards.
This is a classic spacing table for steel pipe.
Support span table from asme b 31 1 v.
Spans are based on using carbon steel pipe a53 gr b filled with water.
Spans are based on insulated and uninsulated lines below 650 f.
It is based on a maximum bending stress of 2300 psi and maximum sag at mid span of 0 10.
1 ft foot 0 3048 m.
Hanger support spacing rod sizes horizontal pipes recommended maximum support span between hangers and rod sizes for straight horizontal pipes.
Recommended maximum space between hangers for straight horizontal pipes and tubes are indicated in the table below.

Regardless of 1 cubic ft.
The values does not apply where loads are concentrated with flanges valves specialties etc.
Of water weighs 62 41 lbs.
In practice longer spans are usually feasible with a deadweight bending stress in the order of 5000 psi to 10 000 psi.

Based on mss table 3 4 based on astm a53 86 many codes require pipe hangers to be spaced every 10 ft.
Spacing and capacities are based on water filled pipe.
Spans are based on 12 1 2 mill tolerance and 065 correction tolerance.
1 gallon u s weighs 8 335 lbs.
Provided the sag between supports remains acceptable.
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 also provided for pipe deflection of 25 mm for all pipe sizes.
These charts are normally mentioned in piping stress analysis project specifications.
If supports are spaced greater than 25 0 consultation with a structural engineer should be performed for additional analysis.
Pipe support span chart is a tabular chart giving a rough idea of supporting distance.
