Bright Annealing Heat Exchanger Sst Coiled Tubing Machine Heat Treating Oven

HVAC Tube Forming Machine Duct Production Line Bright Annealing Pipe Welding Machine Coil Metal Tube Making Machine

Double Head Electric Strip Uncoiler

Structural form: Double-shaft expansion and contraction uncoiler. The mandrel is composed of 4 wedge-shaped blocks. The inner diameter of the coil is tightened through the screw expansion and contraction mandrel. The unwinding speed is controlled by a manual brake. One roll is produced online and one roll is prepared to adapt to continuous production.

√ Higher loading capacity
√ Stainless steel edging to prevent iron ions from contaminating the steel strip
√ Cleaner workshop environment

Self-designed horizontal strip accumulator

√ Max stocking length could reach 200-300M

Forming & welding section
Function: The strip is deformed in stages by alternately arranged horizontal roller stands and rollers in the vertical roll stand to obtain the required stainless steel pipe products of different specifications.

√ The frame adopts integral type to strengthen rigidity and reduce accumulated error.
√ Roller material accepta customization.

Protective atmosphere welding box

Function: Welding the formed strip in a closed protective box.
Structure: horizontal roller device, extrusion device, welding system.

√ Variuos welding type customization aceepted

online bright annealing heat treatment

The stainless steel tube enters the online bright solid solution system after first sizing, and the stainless steel tube in induction heating furnace is given a certain tension (about 1%) through the speed control system. The heat treatment system matches the line speed and the yield is high. The equipment is easy to operate, simple, high degree of automation, and high efficiency of heating power supply. Power supply damage will not occur when the production line fails.
The sealing system of the cooling channel is safe, stable and reliable. Annealing outlet temperature is below 100 °C. The system uses a closed loop softened water cooling system.

Final Sizing

Efficiency

  1. Using electromagnetic control system to correct the arc trajectory, improving working speed at least 25% higher and guaranteeing the welding seam quality. The highest speed could reach up to 12 m/min for the TIG welding with excellent welding seam.

  2. It not only speeds up the efficiency, but also save the consumption and factory's room, with continuous, single tube and on-line heat processing. The minimun processed O.D could be 10-12.7mm. 

Automation
   
  Labor costs saving. One person could monitor 2 production lines in the meanwhile. Our self developed PLC control system could cordinate every section automatically. With HMI touching screen, you could use it easily.

Anti-corrossion

   High quality rollers are made of material SKD11, with vacumm gas quenching. Hardness reaches up to 64-66, with CNC high precision processing.

Accuracy

   Precise CNC processing could ensure the smooth surface with less scratch happenning when forming. Accurate size could controle the tolerance at the range of ±0.5-1.0 mm.

   Visible design of micro adjusting device of roller's lifting, making roller replacement higher operability.Usage
