new machine ready for sale

1. This equipment is specially used for producingΦ19-Φ76mm,δ0.7-3.0mm high-frequency straight seam welded pipe and corresponding square pipe and special-shaped pipe. The composition of equipment is from uncoiler to computer fixed length-cutting saw. Rolling speed can be adjusted correspondingly within suitable range of pipe diameter and wall thickness.

Applicable material: The material of steel strip is general carbon steelQ195，Q235，16Mn and etc hot rolled and cold  rolled ，pre-galvanized-strip steel.

Square pipe production mode: round changed into square.

production mode: continuous

Operation direction of the machine: left feeding or right feeding (determined by the technological arrangement of the user workshop)

Rolling bottom line: Around +760mm (can be customized according to the requirements from customer)

Welding method: high frequency induction welding, 250KW

20—80m/min  Rolling speed: 20-80m/min

Total power consumption of the production line:654KW Voltage：380V/50HZ

producing process

 Raw material (steel strip) → uncoiling → shearing and end welding(TIG welding) → material accumulating → non-power leveling → mill-forming → high-frequency welding → removing burrs outside of weld seam → cooling → sizing → roughly straightening → fixed length cutting → finishing tube

scope of supply: double side hydraulic uncoiler, shear welder, accumlator, forming and sizing machine, cold cutting saw,conveyor table,Solid state HF welding machine 300KW
