Product Introduction

Used in chemical, mechanical, electronic, electric power, medical equipment, aviation, aerospace, communication, petroleum and other industrial fields of metal stainless steel disk, generally 0.5cm to 20mm diameter, thickness of 0.1cm to 2.0mm coil or mosquito coil elbow; Widely used in chemical, machinery, electronics, electric power, textile, rubber, food, medical equipment, aviation, aerospace, communications, petroleum and other industrial fields.

Product Advantages

Stainless steel coil is a type of coil, but is made of stainless steel material processing, can be used in different industries. At present, it has been widely used in chemical industry, machinery, electronics, electric power, textile, rubber, food, medical equipment, aviation, aerospace, communication, petroleum and other industrial fields. So what are its advantages?

1. Stainless steel coil heat transfer using 0.5-0.8mm thin-wall pipe, improve the overall heat transfer performance. With the same heat transfer area, the overall heat transfer deserves 2.121-8.408% higher than that of copper coil.

2. Because the stainless steel coil is made of SUS304, SUS316 and other high quality stainless alloy steel, so that it has higher hardness, the steel degree of the pipe is also significantly improved, therefore, it has strong impact resistance and vibration resistance.

3. Because the inner wall of the stainless steel coil is smooth, the bottom layer thickness of the boundary laminar flow is thinner, which not only strengthens the heat transfer, but also improves the anti-scaling performance.

4. In order to eliminate the welding stress, the steel pipe material used in the stainless steel coil is heat treated at 1050 degrees in the protective gas.

5. Stainless steel coil are used for leakage inspection, pressure test to 10MPA, 5 minutes without pressure drop.

Product Application

Stainless Steel Coil For Various Uses:

Industrial stainless steel coil: heat exchanger, boiler, petroleum, chemical, chemical fertilizer, chemical fiber, pharmaceutical, nuclear power, etc.

Stainless steel coil for fluid: beverage, beer, milk, water supply system, medical equipment, etc.

Stainless steel coil for mechanical structure: printing and dyeing, printing, textile machinery, medical equipment, kitchen equipment, automobile and ship parts, construction and decoration, etc.

Stainless steel bright coil: the stainless steel belt is welded and then the wall is reduced. The wall is reduced from thick to thin. This process can make the wall thickness uniform and smooth, and the wall is reduced and stretched to form the effect of no weld. According to the naked eye is seamless pipe, but its process decision is welded pipe. The PROCESS OF reducing the wall is accompanied by bright annealing, so that the inner and outer wall will not form oxide layer, and the inner and outer bright and beautiful, which is really needed for medical products. The next process needs sizing, that is, large pulling small process, to determine the outside diameter, the outside diameter tolerance can generally reach plus or minus 0.01mm.
