The ERW hollow section production line is a series of machines designed to produce round, square and rectangular steel hollow sections with HF welding from steel coils.
1. General introduction:
The ERW hollow section production line is a series of machines designed to produce round, square and rectangular steel hollow sections with HF welding from steel coils.
The product is widely used in water, oil and gas transportation and structural construction. The equipment employs PLC control system and digital controlled DC motor to ensure premium production. The equipment utilizes ERW forming system, which leads to stable production, smooth pipe surface finish, and easy tooling change.
This machine was made in 2013 year and stopped working in 2023.
