What is the process of seamless elbow?

Seamless elbow is a common pipe connector used to change the flow direction and Angle of the pipe. It is widely used in petroleum, chemical industry, electric power, metallurgy, pharmaceutical, paper making, food, aerospace and other fields. The processing process of seamless elbow will be described in detail below.

1. Material preparation: First of all, we need to prepare seamless steel pipes and elbow blanks. Seamless steel pipe should meet the relevant standard requirements, elbow blank can be selected according to the requirements of the appropriate material.

2. Design and analysis: Design and analysis of elbows according to actual needs and layout of pipeline system. Including the Angle of elbow, radius, wall thickness and other parameters to determine.

3. Heating and bending: the seamless steel pipe is heated to the appropriate temperature, generally using flame heating or resistance heating. The heated steel pipe is bent by force on the bending machine. According to the radius and Angle of the elbow, the ideal bending shape can be obtained by adjusting the parameters of the bending machine.

4. Cooling and annealing:
