Carbon steel pipe is mainly divided into: seamless steel pipe for structure, seamless steel pipe for conveying fluid, seamless steel pipe for medium and low pressure boiler, seamless steel pipe for high pressure boiler, seamless steel pipe for oil cracking
Carbon steel pipe is made of carbon steel pipe, carbon content is about 0.05% ~ 1.35%, is the most common kind of steel pipe, such as :10# steel, 20# steel, Q195, Q235,...
According to the usage standard mainly used :GB/T8162 structure with seamless steel pipe GB/T8163 fluid transmission with seamless steel pipe GB3087 in low pressure boiler with seamless steel pipe GB5310
High pressure boiler with seamless steel pipe GB9948 oil crack with seamless steel pipe

Square tube products are tubular materials with square sections, which have the characteristics of high strength, light weight and corrosion resistance, and are widely used in construction, engineering, machinery and other fields. The production process includes material selection, cutting, forming, welding and surface treatment.
