3PP anti-corrosion steel pipe manufacturer

Hebei Tianze Pipe Industry Co., Ltd. specializes in the production of anti-corrosion steel pipes and anti-corrosion steel pipe coating industry standards. The anti-corrosion pipes processed generally adopt the German D "Steel Pipe Polypropylene Coating" standard. The coating is mainly used as an anti-corrosion layer for pipelines transporting higher temperature media and as an anti-corrosion layer for pipelines in desert areas where the surface temperature is higher and the sunshine time is longer. Therefore, it is obtained on buried water, gas and oil pipelines in areas where the surface temperature is higher and the sunshine time is longer. have become more and more widely used. The two-layer anti-corrosion structure of anti-corrosion pipes. The first layer of adhesive (D) and the second layer of polyethylene are two materials integrated into one. The thickness of each layer is the same as the three layers.

Advantages
Anti-corrosion pipelines have extremely high sealing properties and can greatly save energy, reduce costs and protect the environment during long-term operation.
Strong corrosion resistance, simple construction and fast service life of up to 10 years.
Also has good corrosion resistance and impact resistance under low temperature conditions and low water absorption (less than .%).
At the same time, it has high epoxy strength, low water absorption and good softness of hot melt adhesive, and has high anti-corrosion reliability.
The disadvantage is that the cost is high compared with the cost of other repairing materials.
The three-layer structure polyethylene anti-corrosion layer combines the excellent properties of two anti-corrosion layers, sintered epoxy powder coating and extruded polyethylene. It combines the interface properties and chemical resistance properties of sintered epoxy powder coating with extrusion The mechanical protective properties of the polyethylene anti-corrosion layer combine to significantly improve their respective properties. Therefore, it is very superior as an outer protective layer for buried pipelines. According to relevant information, three layers can extend the service life of buried pipelines to 20 years. It is currently considered the most advanced pipeline external anti-corrosion technology internationally. In my country, three-layer systems have been the first to be applied in oil and gas systems. my country's built Shaanxi-Beijing natural gas pipeline and the Kushan-Shanxi oil pipeline, a recent national key project of nearly a kilometer of west-to-east gas transmission, all use three layers of external anti-corrosion coatings. In the outer ring line of the high-pressure pipeline from Shaanxi to Tianjin, the kilometer-long high-pressure natural gas pipeline to Shaanxi-Beijing line and the underground gas storage pipeline also use three layers. It has become the development direction of the outer anti-corrosion layer of pipelines in the future.

Reasonable price and timely quotation.
There are many factors that affect the performance of the anti-corrosion layer of steel pipes, such as the layout of each process, equipment selection, surface quality, heating method, coating temperature, cooling method, transmission accuracy, material characteristics and detection, etc. Poor control will lead to excessively low coating adhesion. Strict implementation of standardized and scientific operating methods for defects such as thin cracks or bubbles is crucial to controlling defects and ensuring the yield of anti-corrosion pipes.
