ERW Straight Seam Welded Pipe Unit
A straight seam welded pipe unit is a device that takes steel coils, after they have been longitudinally cut and separated into strips of a certain width, and after they have been uncoiled and straightened, into a forming machine. The forming machine uses rollers to bend the steel strips into cylindrical pipe blanks. Then, using the skin effect and proximity effect of high-frequency current, the edges of the steel strip are melted in a very short time. After being squeezed by the extrusion rollers, the surface oxide layer and impurities are squeezed out, and the base material is fused together to form a circular pipe.
Large-diameter round-to-square high-frequency straight seam production line
A straight seam welded pipe unit takes steel coils that have been slit to a certain width, and after uncoiling and leveling, feeds them into a forming machine. Rollers bend the steel into a cylindrical tube blank. High-frequency current, using the skin and proximity effects, melts the edges of the steel strip in a very short time. A pressure roller then squeezes out surface oxides and impurities, fusing the base material to form a seamless tube.

Rollers bend the steel into a cylindrical tube blank. High-frequency current, using the skin and proximity effects, melts the edges of the steel strip in a very short time. A pressure roller then squeezes out surface oxides and impurities, fusing the base material to form a square tube.
Small-diameter high-frequency straight seam production line
A straight seam welded pipe unit takes steel coils that have been slit to a certain width, and after uncoiling and leveling, feeds them into a forming machine. Rollers bend the steel into a cylindrical tube blank. High-frequency current, using the skin and proximity effects, melts the edges of the steel strip in a very short time. A pressure roller then squeezes out surface oxides and impurities, fusing the base material to form a seamless tube.
To meet the needs of continuous pipe welding production, a live coil storage device must be installed before the head and tail shearing and butt welding station of the strip. This ensures that while the strip is being loaded, uncoiled, and prepared for head and tail shearing and butt welding, the live coil continuously feeds the pre-stored strip to guarantee continuous production of the unit.

Submerged arc welding equipment for straight seams
The production process of bending steel plates into straight seam pipes through processes such as roll bending/roll forming/press brake bending; the production of thick-walled steel pipes is completed through submerged arc welding.
