Spiral Pipe is industrial pipe, also known as spiral steel pipe or spiral welded pipe, is a low-carbon structural steel or low alloy structural steel strip in accordance with the angle of a certain helix coil into the tube billet, and then welded pipe joints made.
Let me introduce you to the characteristics and use of spiral tube.
The characteristics of the spiral tube are as follows: Welded pipe production process is simple, high production efficiency, low cost, rapid development. The strength of spiral welded pipe is generally higher than that of straight seam welded pipe, it can produce welded pipe with larger pipe diameter with narrower billet, and can produce welded pipe with different pipe diameter with same width. However, the weld length increases 30~100% and the production speed is lower compared with the straight seam tube of the same length.
As a result, the smaller-caliber welded pipe mostly uses the straight seam welding, the large diameter welded pipe mostly uses the spiral welding.
The main uses of spiral pipe:
Spiral pipe is mainly used in water engineering, petrochemical industry, Chemical industry, power industry, agricultural irrigation, urban construction, is one of the 20 key products developed in China.
For liquid transportation: water supply, drainage, sewage treatment works, transportation of mud, sea water.
For gas delivery: gas, steam, liquefied petroleum gas.
Used for construction: piling Pipe, bridge, Wharf, road, building structure pipe, marine piling pipe, etc. The spiral tube is more prone to corrosion, so it is often used to remove rust to ensure the normal use of the spiral tube.
