Product Description
Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip steel after crimping and welding. Large-diameter or thicker welded pipes are generally made of steel billets directly, while small welded pipes and thin-walled welded pipes are generally made of steel strips directly welded. The production process of welded steel pipe is simple, the production efficiency is high, and there are many varieties and specifications.

Manufacturing Processes
Application
Low carbon steels are often used in automobile body components, structural shapes (I-beams, channel and angle iron), pipes, construction and bridge components, and food cans.
As a result of their high strength, resistance to wear and toughness, medium-carbon steels are often used for railway tracks, train wheels, crankshafts, and gears and machinery parts requiring this combination of properties.
Due to their high wear-resistance and hardness, high-carbon steels are used in cutting tools, springs high strength wire and dies.
