Q235 Seamless Steel pipe
Products
Seamless steel pipe is a kind of steel pipe made of whole round steel perforated with no welds on its surface. According to the production method, seamless steel pipe can be categorized into hot-rolled seamless steel pipe, cold-rolled seamless steel pipe, cold-drawn seamless steel pipe, extruded seamless steel pipe and top pipe. According to the cross-sectional shape, seamless steel pipe can be divided into two categories: round and shaped, of which the shaped pipe includes square, oval, triangular, hexagonal, melon, star and finned pipe and many other complex shapes. The maximum diameter of seamless steel pipe can reach 900 millimeters, and the minimum diameter is 4 millimeters. According to different applications, seamless steel pipe can be categorized into thick-walled seamless steel pipe and thin-walled seamless steel pipe, which are widely used in petroleum, natural gas, chemical industry, electric power, automobile, aerospace and other fields.
Seamless steel pipe is characterized by excellent mechanical properties and resistance to high pressure and corrosion, and its smooth surface and precise dimensions can be used for transporting fluids and used as structural parts. The production process of seamless steel pipe includes the steps of piercing, rolling and drawing, which requires high-precision equipment and high-quality raw materials. In the process of use, it is very important to carry out quality inspection and control of seamless steel pipe to ensure its safety and reliability. As technology continues to advance and demand increases, the production process and quality of seamless steel pipe will continue to improve to meet the needs of various industries.
