Calculating Pipes Weight

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

Ask and Answer: Tie Rod Assembly Configurations

How are tie rods, turnbuckles, and clevises configured?

Tie rods, clevises, and turnbuckles are an important part of many architectural designs. Canopy supports, structural steel bracing, and walkway hangers are a few of the applications that use these assemblies. The unique configuration allows for field adjustments in both length and tension.
Adjustment
Adjustments are possible by threading opposing ends of the rod right hand (RH) and left hand (LH). Another alternative is to provide two clevises threaded RH and use a turnbuckle in the middle that has RH and LH threads. The assembly length and tension is adjusted by rotating the turnbuckle. Both options allow the assembly to be installed and easily adjusted in place.
Grip
The grip on a clevis refers the distance between the legs. This is the area that will be placed over the plate and held by a pin. Generally, the grip size is calculated by the material thickness plus ¼”. Keep in mind the minimum grip is ¾” for #2 through #5 clevises and 1” for #6 and #7.

Pin
Clevis pins are available headed or smooth and are generally secured with a cotter pin connection. In some applications an ASTM A325 structural bolt can also be used to connect the clevis to the structure. Refer to the Diameter of Pin in Inches chart on the clevis page for the appropriate pin dimensions. This chart is designed so that the pin will surpass the matching rod strength.
Galvanizing
Hot-dip galvanized clevises and turnbuckles are available. It is crucial for correct fit that the clevises and turnbuckles are tapped oversize to account for the additional thickness from zinc on the tie rods. To ensure the proper fit Portland Bolt assembles all parts prior to shipping.

ASME/ANSI B36.10/19: pipe sizes, diameters, wall thickness, working pressures

The steel pipe data chart below (download .pdf) can be used to find pipe sizes, diameters, wall thickness, working pressures and more The chart is based on ASME/ANSI B 36.10 Welded and Seamless Wrought Steel Pipe and ASME/ANSI B36.19 Stainless Steel Pipe.

Regardless of schedule number, pipes of a particular size all have the same outside diameter (not withstanding manufacturing tolerances). As the schedule number increases, the wall thickness increases, and the actual bore is reduced. For example:

• A 4 inches (100 mm) Schedule 40 pipe has an outside diameter of 4.500 inches (114.30 mm), a wall thickness of 0.237 inches (6.02 mm), giving a bore of 4.026 inches (102.26 mm)
• A 4 inches (100 mm) Schedule 80 pipe has an outside diameter of 4.500 inches ( 114.30 mm), a wall thickness of 0.337 inches (8.56 mm), giving a bore of 3.826 inches (97.18 mm)

STD, XS and XXS

To distinguish different weights of pipe, three long standing traditional designations are used:

• standard wall - STD
• extra strong wall - XS
• double extra strong wall - XXS

The last two designations are sometimes referred to as extra heavy wall (XH), and double extra heavy wall (XXH).
