High Precision Welded Steel Tube Airway Cold Rolled Coil Bundy Welded Tubes

TORICH Automotive Refrigerator Airway Cold Rolled Coil Bundy Welded Tubes

Introduction:

Application: It is mainly used in oil pressure gauge pipeline, fuel pipeline, brake pipeline and similar devices in automobile industry, refrigeration industry and heater manufacturing industry. It can also be widely used to replace copper pipe and reduce the use cost.

Advantage: Due to its unique double-layer structure and special manufacturing process, it has some characteristics that can not be compared with other pipes:
1. High precision cold-rolled high-quality low-carbon steel strip and exquisite precision rolling technology ensure the precision of outer diameter and wall thickness and good concentricity of pipe;
2. 360 ° along the pipe wall, weld the joint surface to ensure that the Bundy pipe will not leak;
3. At the same time, the pipe has the characteristics of high blasting strength and high anti vibration fatigue limit;
4. In the manufacturing process of Bondi tube, the lubricating oil with low carbon content is used to make its inner surface extremely clean, and the residue on the inner surface is less than 0.05g/m2.
5. Because the Bondi tube is made of high-quality low-carbon steel, it is easy to bend and form, easy to weld and easy to process tube ends of various shapes.

QUALITY CONTROL:
1. Incoming Raw Material Inspection
2. Raw Material Segregation to avoid steel grade mix-up
3. Heating and Hammering End for Cold Drawing
4. Cold Drawing and Cold Rolling, on line inspection
5. Heat Treatment, +A, +SRA, +LC, +N, Q+T
6. Straightening-Cutting to specified length-Finished Measuring Inspection
7. Machanical Testing in own labs with Tensile Strength, Yield Strength, Elongation, Hardness, Impact, Mictrostruture etc
8. Packing and Stocking
