A large number of pipes are used to escort fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is light, so they are also commonly used to manufacture mechanical parts and engineering structures. It is also used for consumption of various conventional weapons. Square tubes are commonly used in various building structures and engineering structures, such as building steel for building beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, warehouse shelves, etc. Square tubes play a very important role in the construction industry.

There are more and more manufacturers of seamless square and rectangular tubes. The demand and market sales are accumulated day by day, which means that the manufacture of seamless square and rectangular tubes is stopped by virtue of many advantages and characteristics of seamless square and rectangular tubes. Seamless square and rectangular tubes can be said to be icing on the cake in terms of processing technology and manufacturing process. The wear resistance and ductility of the process are relatively good. The products manufactured are smooth in appearance and superior in performance! The seamless square and rectangular tube has good strength, toughness, plasticity, welding and other process properties, and has good ductility. Its alloy layer is firmly attached to the steel base. Therefore, the seamless square and rectangular tube can stop cold punching, rolling, wire drawing bending and other forming without damaging the coating. It is suitable for ordinary processing such as drilling, cutting, welding, cold bending and other processes. The seamless rectangular tube after hot galvanizing has a bright and beautiful appearance. Seamless square and rectangular tube can be divided into seamless tube and welded tube. Seamless square and rectangular tube is extruded from seamless round tube. Generally, it can be selected and used according to detailed requirements. Due to its excellent performance, seamless rectangular tubes are widely used in such aspects as glass curtain walls, power towers, communication networks, water and gas escorts, wire casings, houses, bridges, metal structures, etc.

Wall thickness grading of rectangular pipes - extra thick rectangular pipes, thick rectangular pipes, thin rectangular pipes. The thick wall rectangular pipe is a galvanized welded square pipe used for low pressure fluid escort, which is only used for ordinary low pressure fluid, mainly used for water, gas, oil, hot water or steam escort; Galvanized welded thick wall rectangular pipe for low pressure escort is mainly used to escort ordinary low pressure fluids such as water, gas, oil, hot water or steam. The surface of the square pipe adopts hot galvanizing or cold galvanizing anti-corrosion process. The rectangular thick wall mining infusion welding square tube is mainly used for mining air pressure welding, row welding, shaft drop welding, etc.
