Characteristics and application of small diameter spiral welded pipe

　　Although small caliber spiral welded pipe is small, its function is a lot. So what the features and uses of small diameter spiral welded pipe are?

　　Features of small-diameter spiral welded pipe:

　　The production process of spiral welded pipe is simple, but it has high production efficiency. It can use material to form a larger pipe diameter pipe, it can also use the same width of preform body to product pipes with different diameter. However, compared with the same LSAW steel pipe, the length of weld seam is increased by 30% to 100%, and its production rate is low. Therefore, the smaller diameter of the steel pipe mostly use straight welding, large diameter welded pipes mostly use spiral welded pipe.

　　Uses of small-diameter spiral welded pipe:

　　Spiral welded pipe is mainly used in tap water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, and it is one of the 20 key products for the development of China. It is used for liquid delivery: water supply, drainage. It is used for gas transmission: gas, steam, liquefied petroleum gas. It is used for the structure: piling pipe, bridge girder, the pipe for wharf, road, building structure and so on.
