What you need to know about spiral pipe

​Common standards for spiral pipes are generally divided into SY/T5037-2000(ministry standard, also known as spiral welded steel pipe for common fluid transmission pipelines), GB/T9711.1-1997(National standard, also known as the technical delivery conditions of steel pipe for petroleum and Natural gas Industry), API-5L(American Petroleum Institute, also known as pipeline steel pipe;It is divided into TWO grades: PSL1 and PSL2) and SY/T5040-92(spiral welded pipe for pile).

Process of Producing Spiral Steel Pipe

How to produce all kinds of spiral steel pipes from a piece of steel? Today I will introduce to you all the steps in the production of spiral steel pipes.

Advantages and uses of Petroleum Cracking Pipes

Petroleum cracking pipe is a kind of long strip steel with hollow section and no joint around it. Petroleum cracking pipe is a kind of economic section steel.

Forming process and development of thick-wall spiral steel pipe

Thick-wall spiral steel pipe refers to a spiral steel pipe whose wall thickness is slightly thicker than that of an ordinary spiral steel pipe. Compared with the ordinary wall thickness spiral steel pipe, the advantages are: high compressive strength, high impact strength, high safety performance, and longer service life. The implementation standards are 5037, 9711 and api.

The uses of aluminum alloy row pipe

Aluminum alloy pipes and seamless steel pipes are the same, can be applied to ammonia working fluid, can also be applied to Freon working fluid. The surface of aluminum alloy row pipe is provided with a 11渭thick anti-corrosion layer, which is more suitable for low temperature and humid environment than seamless steel pipe row pipe.
