The seamless steel pipe has a hollow cross-section and is widely used as a pipeline for conveying fluids, such as pipelines for conveying oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe has the same bending and torsion strength and lighter weight. It is a kind of economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction and other steel pipe manufacturing ring parts, which can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing hours. It has been widely manufactured with steel pipes.

The production process of straight welded pipe is simple

The production process of straight welded pipe is simple, the production efficiency is high, the cost is low, and the development is fast. The strength of spiral welded pipe is generally higher than that of straight welded pipe, and welded pipe with larger diameter can be produced with narrower billet, and welded pipe with different diameter can also be produced with billet of the same width. However, compared with the straight seam pipe of the same length, the weld length is increased by 30 to 100%, and the production speed is lower. Therefore, the smaller diameter welded pipe is mostly straight seam welding, and the large diameter welded pipe is mostly spiral welding.

What is spiral welded steel pipe

Spiral welded steel pipe refers to the steel pipe with joint surface after bending steel strip or steel plate into round, square and other shapes. According to different welding methods, it can be divided into arc welding pipe, high frequency or low frequency resistance welding pipe, gas welding pipe, furnace welding pipe, Bondi pipe and so on. According to the shape of the weld can be divided into straight seam welded pipe and spiral welded pipe. Electric welded steel pipes are used in oil drilling and machinery manufacturing. The furnace welded pipe can be used as water and gas pipe, and the big mouth straight seam welded pipe can be used for high-pressure oil and gas transportation. Spiral welded pipe is used for oil and gas conveying, pipe pile, bridge pier, etc. Welded steel pipe has lower cost and higher production efficiency than seamless steel pipe.
