Production process of welded steel pipe
The development of steel pipe production technology began with the rise of bicycle manufacturing, the development of petroleum in the early 19th century, the manufacture of ships, boilers, and aircraft during the two world wars, the manufacture of thermal power boilers after the Second World War, the development of the chemical industry, and The drilling and transportation of oil and natural gas have strongly promoted the development of the steel pipe industry in terms of variety, output and quality.

The difference between seamed stainless steel pipe and seamless stainless steel pipe
Stainless steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used to produce various conventional weapons, barrels, shells, etc.

Various classifications of stainless steel flat bar
Stainless steel flat bar is a kind of section steel. Stainless steel flat bar is generally divided into hot-rolled flat steel and cold-drawn flat steel. The general delivery state of hot-rolled 304 stainless steel flat steel surface is pickling, and the general delivery state of cold-drawn stainless steel flat bar is wire drawing and polishing.
