API 5L LSAW steel pipe supply range
- LSAW steel pipe: 406.4 mm to 1422.0 mm
- Range of Thickness: 6.0 mm to 30.0 mm
- Ends Type: Beveled ends, Plain ends
- Range of length: 20FT, 40FT or customized
- Protection Caps in plastic or iron available
- Surface appearances: Natural, Varnished, Black painting, 3PE, FBE, etc
Weight of 20-inch steel pipe
- Pipe weight (kg/m) = (O.D. – W.T. ) * W.T. *0.0246615
- For example:
- O.D. = 20 inch steel pipe outside diameter = 508.0 mm
- W.T. = Sch 40 = 15.09mm
- Weight (kg/m) = (508.0 mm – 15.09 mm) * 15.09 mm *0.0246615 = 183.432 kg/m

Pipe end of 20-inch steel pipe
1. Pipe end protector.
1) 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: 1.6mm±0.8mm
