Large-diameter seamless steel pipes can be divided into straight seam arc welded steel pipes and straight seam submerged arc welded steel pipes according to traditional processes. The production process of straight seam welded pipes is simple, low-cost, fast-developing, and high-production efficiency. Seamless steel pipes are square, round, and rectangular steel pipes with hollow cross-sections and no joints around them.
First, the production steps of large-diameter seamless steel pipes are explained
1. Large-diameter seamless steel pipes are made of a whole piece of metal and have no seams on the surface. Steel pipes are called seamless steel pipes. Seamless steel pipes have hollow cross-sections and are suitable for conveying fluids such as oil, water, and some solid materials.
2. Large-diameter seamless steel pipes are widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames, steel scaffolding, etc. Straight seam steel pipes refer to steel pipes with welds parallel to the longitudinal direction of the steel pipe. When the seamless pipe and the straight seam steel pipe have the same diameter and wall thickness, the pressure and robustness of the seamless pipe are much greater than that of the straight seam steel pipe.
3. Large-diameter seamless steel pipes and welded steel pipes are steel pipes made by pressing steel plates or steel strips.
Second, large-diameter seamless steel pipe methods.
1. Large-diameter seamless steel pipes are much more resistant to corrosion, pressure, and high temperatures than welded steel pipes. When the diameter and wall thickness of seamless pipes and straight seam steel pipes are the same, the pressure and robustness of seamless pipes are much greater than those of straight seam steel pipes.
2. Large-diameter seamless steel pipes have hollow cross-sections and are suitable for conveying fluids such as oil, water, and some solid materials. The production process of straight seam welded pipes is simple, low-cost, fast-growing, and high-efficiency.
3. Large-diameter seamless steel pipes are much more resistant to corrosion, pressure, and high temperatures than welded steel pipes. Welded steel pipes are steel pipes made by pressing steel plates or steel strips.
