Weight of 36-inch steel pipe

Pipe weight (kg/m) = (O.D. – W.T. ) * W.T. *0.0246615

For example:

O.D. =36 inch steel pipe outside diameter = 914.4 mm

W.T. = Sch XS = 12.7 mm

Weight (kg/m)= (914.4 mm – 12.7 mm) * 12.7 mm *0.0246615 =282.413 kg/m

Pipe End of 36-inch Steel Pipe

1. Pipe end protector.

1) The Thickness of Pipe End Protector

We will choose the proper thickness of pipe end protector. If the end protector is too thin, it will easy to drop and could not protect the pipe end properly when loading pipes.

2) Iron Pipe End Protector

LSAW pipe size is very large. When we loading pipes, we usually use folk-lift. So we usually use metal end protector.

Of course, there also have plastic kind of pipe end protector. All this is according to customers’ requirements.

2. Pipe End Beveled

1) Pipe End Bevel Angle Tolerance: 30°±5°

2) Pipe End Root Face: 1.6 mm ± 0.8 mm
