Q195 Stainless steel square pipe Features
Most square tubes are mostly steel tubes, which are unpacked, leveled, crimped and welded to form round tubes, which are rolled into square tubes and then cut into the required length. It is generally 50 square tubes per package in spot with large specifications in the majority of 10*10*0.8-1.5~~500*500*10-25, square tubes are divided into structural square tubes, decorative square tubes, construction square tubes, mechanical square tubes and so on. Square pipe is a name for square pipe, that is, steel pipe with equal length on both sides. It is made of strip steel after processing and rolling. Square tube: generally, strip steel is unpacked, leveled, crimped, welded to form a round tube, and then rolled by the round tube into a square tube and then cut into the required length.

Processing Technology Of Q195 Stainless steel square pipe
Square tube is a kind of hollow square cross section light thin wall steel tube, also known as steel refrigeration bend section. It is made of Q235 hot rolled or cold rolled strip steel or coil plate as base material by cold bending forming and then by high frequency welding made of square section shape and size of steel. In addition to the thickening of the wall, the corner size and edge flatness of hot rolled extra-thick wall square tube reach or even exceed the level of resistance welding cold forming square tube. Good comprehensive mechanical properties, weldability, cold, hot working and corrosion resistance, with good low temperature toughness.
