Do you know the welding pipe manufacturing process?

The development of steel pipe production technology began with the rise of the bicycle manufacturing industry. The early 19th-century development of oil, the construction of ships, boilers, and aircraft during the two World Wars, the post-World War II construction of thermal power boilers, the development of the chemical industry, and the drilling and transportation of oil and natural gas all powerfully propelled the development of the steel pipe industry in terms of variety, output, and quality.

Steel pipes are classified into two types according to their production methods: seamless steel pipes and welded steel pipes. This article will mainly introduce welded steel pipes.

Welded steel pipes, also known as seamless steel pipes, are produced by bending billets (steel plates and strips) into the required cross-sectional shape and size using various forming methods, and then welding the seams together using different welding methods.

Straight seam high-frequency welded pipes (ERW) are produced by forming hot-rolled coils using a forming machine, then using the skin effect and proximity effect of high-frequency current to heat and melt the edges of the billet, and finally pressure welding them under the action of extrusion rollers.
