Product Introduction

Stainless steel industrial pipe, super long coil, U-shaped pipe, pressure pipe, heat exchange tube, fluid pipe, spiral coil product features: high temperature steam resistance, impact corrosion resistance, ammonia corrosion resistance; Anti scaling, not easy to stain, anti oxidation corrosion; Long service life, reduce maintenance time, save money; Pipe assembly technology is good, can directly change the pipe, safe and reliable; Pipe wall uniformity, wall thickness is only 50-70% of copper pipe, the overall thermal conductivity is better than copper pipe; It is an ideal heat exchange product for old unit transformation and new equipment manufacturing. It can be widely used in petrochemical industry, electric power, nuclear industry, medicine, food and other industries.

Product Advantages

1. Hi-Tech Manufacturing Equipment:
Our core manufacturing technical is Japanese core reduction wall drawing and bright annealing technology.

2. Strong R&D Strength:
We have 5 engineers in our R&D centre, one of them are doctors from University of Science and Technology of China, the rest of them’s major are mechanical Design.

3. Strict Quality Control:
3.1 After the incoming materials, we use our advanced spectrum tester to test all the steel strips to check if they are qualified, and then they can be put into production.
3.2Has good mechanical properties,corrosion resistance,no leakage, pressure resistance.
3.3The company has passed National CCS ship inspection certification, ISO9001 quality certification, CE.
3.4 Finished Products Testing.
1) The replacement time of our molds is 3 months. If the molds are not severely worn, they will still be replaced with new ones;
2) The pipeline is a full inspection, not a random inspection (the test items are hardness test, tensile test compliance, hydraulic test, etc.).

4. OEM & ODM Acceptable:
Customized sizes and shapes are available. Welcome to share your drawings with us, let’s work together to make life more creative.

Product Application

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.
