Description du moulin à tubes CG-219 de soudure par résistance électrique

La ligne de production de tubes soudés longitudinaux à haute fréquence de la ligne de production de tubes soudés par résistance électrique 219 est conçue pour produire des tubes soudés de 89 mm à 219 mm de diamètre extérieur et de 4,0 mm à 8,0 mm d’épaisseur de paroi, ainsi que des tubes carrés et rectangulaires correspondants.

Avantages du moulin à tubes de la soudure par résistance électrique 219

Contrôle électrique et réglage automatique, haute précision, vitesse de changement de rouleau élevée
Avec la technologie de formage carré direct, un ensemble de rouleaux peut produire toutes les tailles de tuyaux
Processus de formage économisant le rouleau jusqu’à 60%


Double Cone Decoiler is used to support the coil and provide raw materials for the production line. The reel is cantilever type, pneumatic expansion and contraction; in order to maintain the tension of the strip and prevent loose coiling, the reel adopts pneumatic brake.

Shearing Welding Machine2

Shearing and Automatic Welding Machine is connect the strips after cutting the preceding coil tail end and the succeeding coil top end and being welded together by CO2 gas shielding welding to keep the Pipe Welding Line running continuously. Type: Automatic welding by TIG welder

Tube Mill Accumulator

The vertical accumulator is used to store steel strips to ensure continuous operation of the host when welding two coils. Occupy small space.

The horizontal accumulator is used to store steel strips to ensure continuous operation of the host when welding two coils.
Advantage: The feeding is more stable, without bending, while reducing the resistance of the feeding, it will not cause damage to the galvanized layer surface, and the noise is relatively lower.

Forming and Sizing Unit

The steel strip of a certain width is bent into corresponding specifications of round pipe, rectangular pipe or open profile through roll forming. This unit consists of five parts: forming machine, welding machine, cooling part, sizing machine, and straightening machine.

High frequency welding equipment

High frequency welding equipment designed for both single and dual coil induction application and HF contact welding processes, these welders offer optimal flexibility for your production. Power range: from 150 to 500kW, Low industrial water consumption

Cold Flying Saw

Commonly known as chopping saw, computer flying saw, also called friction saw. High-speed cutting is accompanied by high temperature and sparks, and the cutting end surface is purple.
