Q235B thick-walled spiral steel pipe is a high-strength, corrosion-resistant, high-temperature, and high-pressure steel pipe that is widely used in petroleum, natural gas, chemical industry, electric power, aviation, aerospace, rail transportation, and other fields. This steel pipe has excellent mechanical properties and corrosion resistance and is widely used in various fields.
Q235B thick-walled spiral steel pipe is made of low-carbon steel. Its main components are iron, carbon, silicon, manganese, etc., and certain alloying elements are added, such as vanadium, niobium, titanium, etc., to improve the strength and corrosion resistance of the steel pipe. performance. The surface of the steel pipe has been sandblasted and pickled to make it smooth and free of oxides and impurities, thus ensuring its corrosion resistance during use.
The production of Q235B thick-walled spiral steel pipe adopts spiral steel pipe production, that is, the steel plate is first rolled into a tube shape, and then rolled through a spiral curling machine for welding and shaping. It has the advantages of high production efficiency, low cost, and short production cycle, and can greatly improve the production efficiency and quality of steel pipes.
Q235B thick-walled spiral steel pipe has excellent mechanical properties and corrosion resistance. Its tensile strength is 375-500MPa, yield strength is 235MPa, and elongation is more than 25%. At the same time, the steel pipe has good corrosion resistance, can withstand the erosion of various media such as acids, alkalis, and salts, and has a long service life.
Q235B thick-walled spiral steel pipe has a wide range of applications.
In the fields of petroleum, natural gas, chemical industry, etc., the steel pipe is widely used to transport oil, gas, chemicals, water, and other media. It can also be used in construction projects such as buildings, bridges, tunnels, airports, and docks. In the fields of aviation, aerospace, rail transportation, and other fields, the steel pipe also has broad application prospects.
In short, the Q235B thick-walled spiral steel pipe is a unique steel pipe product with excellent mechanical properties and corrosion resistance and is widely used in various fields. In future development, with the advancement and improvement of science and technology, the performance of the steel pipe will be further improved, and its application scope will be wider.
