Welded Steel Pipe

Product Introduction

Welded pipe is an electric welded round pipe that is an alternative to steel pipes.It is a structural grade tube that is suitable for a wide variety of applications where dimensional accuracy and precision tolerances is not a primary concern.A raised weld seam is present inside the pipe.

Spiral welded steel pipe is a kind of practical steel pipe, now it has been widely used in small and medium-sized construction site construction facilities, not only that, spiral steel pipe is often used in mining, power, construction and various pipeline systems, one of the important industries.

On the basis of the original is trying to research this more excellent quality of new spiral steel pipe, the purpose is to spiral steel pipe for everybody to create greater profits for pressure fluid transmission with spiral seam submerged arc welding steel pipe. Spiral welded pipe industry investment risk and prospect consulting analysis report released by China industry research network shows that spiral welded pipe is widely used in the fields of tap water engineering, petrochemical industry, hydropower station, power industry, agricultural irrigation and rural construction.Spiral steel pipe is widely used in agriculture, chemical industry, construction, water conservancy, petrochemical industry.
