Introduction to Steel Pipe
Steel pipes are tubular products made of steel, which are widely used in various industries due to their excellent mechanical properties, durability, and versatility. They can be classified into different types according to their manufacturing methods, such as seamless steel pipes and welded steel pipes. Seamless steel pipes are produced by piercing a solid billet to form a hollow tube, which have high strength and good pressure - resistance, often used in high - pressure applications like oil and gas transportation, power generation, and mechanical engineering. Welded steel pipes, on the other hand, are made by welding steel plates or strips together. They are more cost - effective and are commonly used in construction, water supply and drainage systems, and general structural applications.
