Welded steel pipe, also known as welded pipe, is made of steel plate or strip after crimping forming welded steel pipe. Welded steel pipe production process is simple, high production efficiency, variety of specifications, less investment in equipment, but the general strength is lower than seamless steel pipe.

Seamless steel pipe is a round, square and rectangular steel with a hollow section and no joints around it. Seamless steel pipes are made of steel ingots or solid tube blanks through perforation to make capillaries, which are then hot-rolled, cold-rolled or cold-drawn.

Alloy steel pipes are mainly used for high-pressure and high-temperature pipelines and equipment such as power plants, nuclear power, high-pressure boilers, high-temperature superheaters and reheaters. They are made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel. by hot or cold rolling.
