Comparison of advantages and disadvantages of spiral steel pipe and straight seam steel pipe
The weld seam of the spiral steel pipe is longer than that of the straight seam steel pipe. If the pipe length is L, the weld seam length is L/cos(θ). However, most of the defects of steel pipes are concentrated in the weld seam and the heat-affected zone. The long weld seam m...Read more -
What is the suitable temperature for welding straight seam steel pipe
Welding, also known as welding, is a manufacturing process and technology that can join metal or other thermoplastic composite materials such as plastics by applying heat, high temperature, or pressure. There are three welding methods: 1. Welding. The workpiece is heated to fo...Read more -
Is there any difference between HFW steel pipe and ERW steel pipe
The difference between ERW steel pipe (straight seam electric resistance welded steel pipe) and HFW steel pipe (high frequency welded steel pipe) is mainly the principle. As the name implies, resistance welding is a method in which pressure is applied through electrodes after ...Read more -
