Introduction of Production Lines
1. Introduction of Galvanizing Line.
- a. Use of a track strap feeding method to keep tube surface smooth and scratch free.
- b. Process is fully controlled by process control machine which is run under closed balanced tension; tube running is stable.
- c. AC frequency conversion speed control, stable running in wide speed range of 10-50 m/min.
- d. Advanced Germany technology is introduced, and it is the only facility to continuously produce color zinc coating, zinc-iron alloy coating and olive green passivation tubing.
- e. A wide range of coating thickness and thickness can be customized according to client¡¯s need.
- f. Advanced product collecting device is equipped. Coil or straight products are available per client¡¯s requirement and can be finished once; accordingly second process damage will be avoided.
2. Introduction of Cut-to-Length Line.
- a. Track strap feeding method is used to keep tube surface smooth and scratch free.
- b. Cut-to-length dimension setting and non-scrap cutting to keep smoothness of internal or external surface.
- c. Frequency conversion speed control to keep dimension precision.
- d. Precise eddy current flaw detector is used to keep pipe quality.
- e. Automatic labeling system to manage and record tubing automatically.
- f. Automatic selection system to separate standard and defective products effectively.
- g. Process and programmable controlled machine is used to do tube feeding, detection, labeling, cutting, selecting and collecting.
- h. Process control machine to save and file all quality control record.
3. Introduction of Hot Dipped Zinc Coating Line.
- a. A wide range of coating thickness (10¦Ìm¡ª28¦Ìm).
- b. Process is fully controlled by a process control machine which is run by closed loop and balanced tension; tube running is stable.
- c. AC frequency conversion speed control, big running speed range, stable running at 10-100 m/min.
- d. Extended zinc bath; tube is dipped into an alloy liquid; lengths up to 5m are available.
- e. Zinc bath temperature is continuously controlled by three steps electrical heating and PID control system. The temperature control difference is ¡À2¡æ.
- f. Pressure, flow and cooling time are adjustable by controllable wind blade system according to client¡¯s requirement.
- g. Automatic press-down system to maintain reliable and simple equipment operation.
- h. Closed loop pre-heating is set up before galvanizing; preheating temperature is unchangeable regardless of speed changes.
- i. No abrasion soft drag to make tube surface smooth and scratch free.
- j. Auxiliary compass gauge to keep tube roundness after hot coating.
- k. Hot coated passivation treatment to get better corrosion resistance.
- l. Non floriated zinc galvanized tubing, small floriated zinc galvanized tubing, and zinc-aluminum alloy tubing and aluminum-zinc alloy tubing are all producible.
4. Introduction of Plastic Coating Line.
- a. Efficient passivation treatment before coating so that the coating layer has strong adhesive ability.
- b. Process is fully controlled by a process control machine which is run under closed loop and balanced tension; tube running is stable.
- c. AC frequency conversion speed control system and wide speed range; stable running at 5-40 m/min.
- d. 18 meter extended solidification furnace to get enough solidified coating.
- e. Three-step far infrared electricity heating and PID control system to continuously control the solidification temperature and keep the temperature difference at ¡À2¡æ.
- f. Pressure, flow and cooling time is adjusted by controllable wind blade system according to client¡¯s requirement.
- g. Closed loop pre-heating before galvanizing; preheating temperature keeps stable regardless of changes in speed.
- h. No abrasion soft drag to make tube surface smooth and scratch free.
- i. Auxiliary compass device to keep the tube roundness after plastic coating.
- j. Olive green passivation tubing, PVF coated tubing and PVDF coated tubing are available.
