Different companies are manufacturing steel pipes in different shapes. Big companies are using these pipes for a variety of reasons. There are some who assume that the seamless steel pipe is continuously barrel-shaped and straight.
Plastic composite pipe for hot-dip galvanized steel substrate, the molten powder coating technology in the inner wall (wall when needed also) made of plastic coating, excellent performance.
Welded steel pipe, also known as, is a steel plate or strip after curl forming welded steel. Welded steel pipe production process is simple, high production efficiency, different specifications, less capital equipment, but the general strength of less than seamless steel tubes.
Is a hollow section, no seams around the long bar of steel. Steel hollow section, a large number of pipes used for transporting fluids, such as transportation of oil, gas, gas, water and some solid materials, pipes and so on.
