Round pipes «Buy Pipe»

Round pipe is a common type of rolled metal, which has a regular geometric shape in the form of a circle in cross section. It is used for the installation of building structures, fences and various wired communications. Manufactured from low alloy and carbon steel grades. It has a large number of species and varieties. The main technical characteristics and assortment are regulated by such norms EN 10219 S235, S275, S355; EN 10305 S235, S275, S355; ASTM. To increase the strength, they undergo additional, thermochemical processing. It is also possible to apply an additional protective layer.

Round pipe: features

Round pipe has long appeared on the metal rolling market. The product is made of high quality carbon, low alloy steel. Tubular structures are strong, reliable, durable in operation, used in various areas of human life. Due to the excellent technical and operational characteristics, the round steel pipe enjoys high and well-deserved popularity.

Manufacturing process

A high-tech round pipe is produced in stages. That is, the production of this rolled metal product consists of several operational stages. Initially, the steel tape is twisted. When using this operation, the GOST round pipe takes on a standard look. High-voltage radio frequency welding is used to connect the seam.

Seam edges get hot.
Folds into a secure seam.
Pressed under high pressure.
