Product Parameters
ERW (Electrical Resistance Welding) pipes are manufactured by cold forming of steel coil into a round cylindrical shape and are used in various engineering purposes. They are round pipes welded from steel plates with longitudinal welds. Pressure welding is carried out under the action of squeeze rollers. The production process of welded steel pipes is simple, the production efficiency is high, the varieties and specifications are many, and the equipment is few, but the general strength is lower than that of seamless steel pipes. ERW pipes are commonly used to transport oil, natural gas and other vapor-liquid objects, and can meet various requirements of high and low pressure.

Seamless Steel PipeSeamless steel pipe is a kind of long steel with hollow section and no seams around it. It is a kind of economic section steel,seamless steel pipe according to the different cross sectional area shape can be divided into round pipe and special-shaped pipe. Using seamless steel pipe to manufacture ring parts can improve the material utilization rate, simplify the manufacturing process, and save the material and processing time. Widely used in manufacturing structural parts and mechanical parts etc.View Products
Boiler PipeBoiler pipe refers to the pipes used in boilers and related equipment. It is usually made of seamless steel pipes and has high pressure and temperature resistance. The main function of the boiler pipe is to transport high-temperature and high-pressure media to ensure the stable and efficient operation of the boiler system.View Products- Square PipeSquare steel pipe is also known as square and rectangular cold bending hollow steel,referred to as square pipe and rectangular pipe. It is a kind of joint name of square pipe and rectangular pipe,that is,the steel pipe with equal and unequal side length,it is made of strip steel processed by technology.
Generally,strip steel after unpacked,flattened,crimped,welded round pipe,then rolled into square pipe, and then cut into the required length.View Products
