Some standards for Spiral steel pipe

August 03, 2018

Some standards are suitable for spiral Steel Pipe, they are divided into below:

SY/T5037-2008 (parts, also known as common fluid transmission pipeline with spiral seam submerged arc welded steel pipe),
GB/T9711.1-2008 (GB, also known as the oil and gas industry transport steel pipe Technical conditions for delivery Part I: Grade A

Steel Pipes (required strictly GB/T9711.2 Grade B steel pipes)),
API-5L (American Oil Institute, also called pipeline steel pipes; which are divided into two grades of PSL1 and PSL2), SY/T5040-

2008 (Spiral welded steel pipe for piles).
SY/T5037-2008 is the Ministry of Petroleum set up standards are generally called the standard
GB/T9711.1-2008 National spiral pipe, oil and gas industry transmission steel pipe, Grade A general low pressure fluid conveying

spiral seam high frequency welded steel pipe (SY5039-2000) is a hot rolled steel strip coiled tube, regular temperature spiral

molding High-frequency lap welding is used to weld high-frequency spiral welded steel pipe for general low-pressure fluid delivery.

Spiral welded steel pipe for piles (SY5040-2000) is made of hot-rolled steel strips as tube blanks, and is usually thermo-screwed.

It is made by double-sided submerged arc welding or high-frequency welding. It is used for civil construction structures, piers and bridges.
