Dimensions for pipe

Dimensions and materials conform to MSS-SP-114, Class 150 or Class 1000, Threaded or Socket-Welding. Pipe Threads conform to ASME B1.20.1. Cast 150 LB Pipe Fittings are manufactured from material conforming to ASTM-A-351 (CF8/304, CF8M/316, or CN7M/A-20). ASP Cast 150 LB Fittings are suitable for use at pressure temperature ratings for MSS-SP-114 Class 150 Fittings (300 psi CWP / 150 psi SWP). ASP Forged/Barstock 150 LB Fittings are manufactured from forged or wrought barstock materials conforming to the chemistry of ASTM-A-182 (F304 or F316) or ASTM-B-473 (A-20) in a proper state of heat treatment to provide desired mechanical properties and corrosion resistance. ASP Forged/Barstock 150 LB Fittings are suitable for use at pressure temperature ratings for MSS-SP-114 Class 1000 Fittings (1000 psi CWP). All ASP 150 LB Stainless Steel Pipe Fittings are identified with the ASP Trademark, Nominal Pipe Size, and Material Grade.

A weight calculating formula for steel pipes

If the outside diameter and the wall thickness of a steel pipe is known, the weight per foot can be expressed as:

m = 10.68 (d_o - t_w) t_w         (1)
where
m = weight per foot (lbs/ft)
d_o = outside diameter (inches)
t_w = wall thickness (inches)

Example - Weight of 4" Schedule 40 Steel Pipe

The outside diameter (d_o) of 4" Schedule 40 Steel Pipe is 4.500 inches. The wall thickness is 0.237 inches. The weight per foot can be calculated using (1) as:

m = 10.68 ((4.500 in) - (0.237 in)) (0.237 in)
= 10.79 lbs/ft
