114.3x6.00 stainless steel ASME Standard Steel Pipe 5 D Bend
The bend is bent by a complete set of bending die, which is divided into two processes: cold simmering and hot pushing. No matter what kind of machinery, equipment and pipelines, most of them use bends, which are mainly used for oil, gas and infusion.
Cold bend is a bending process at normal temperature without heating or changing the material structure, which is called cold bend.
Production process of hot bend: after blanking the straight pipe, put a sensing ring on the part of the steel pipe to be bent through the bend pusher, clamp the pipe head with a mechanical rotating arm, and apply medium frequency current to the sensing ring to heat the steel pipe. When the temperature of the steel pipe rises to the plastic state, push it with mechanical thrust at the rear end of the steel pipe for bending, and the bent steel pipe is quickly cooled with coolant, so that it can be heated Bend the bend continuously while pushing, bending and cooling.
Hot bend is mainly used in building arc steel structure, tunnel support, roof bending beam, subway engineering, aluminum doors and windows, ceiling, cylindrical inner framework, balcony handrail, shower door, production line track, fitness equipment and other industries.
