FX89 extended 127 welding pipe unit

The production line is a special equipment for the production of straight seam welded pipe in metallurgy, construction, transportation, vehicle and other industries.

With strip steel as raw materials, through cold forming and high-frequency welding methods, the production of the required specifications of round pipe, square pipe and shaped pipe.

The equipment adopts advanced pass technology, stable operation, convenient operation and maintenance, and reaches the advanced level of the same industry in structure and precision.

Production line process flow
Raw material (strip coil) – feeding – shear butt welding (manual welding) – storage – feeding molding – high frequency welding – external burring – cooling water jacket – sizing and straightening – cold cutting – blanking (palletizing manual dressing) – inspection – storage.

Molding and sizing main engine

It is the main equipment in the welding pipe production line.

It can continuously roll the long steel strip of a certain specification into a tube and weld it into a tube. It can produce both round pipe and special-shaped pipe.

This unit adopts the principle of roll forming, high-frequency welding pipe can continuously produce certain specifications of steel pipe, heating method adopts induction welding, that is, feed a certain specification of steel strip into the machine, through the forming roller to coil steel strip into tube billet, and then use the skin effect and proximity effect of high-frequency current to make the current highly concentrated on the tube side welding surface, so that the tube side is heated to the welding temperature quickly.

And in the extrusion roll to complete the welding, after cooling, sizing and rough straightening and become the required specifications of the steel pipe, the unit forming using the bottom line horizontal method, roll using double radius pass, the unit is composed of forming section, welding section, sizing section.
