Chinese Professional Hot Dipped Galvanized Square Pipes - Powder coated plastic steel tube – Zheyi Detail:

Powder coated plastic steel tube, Also known as coated plastic pipe, steel-plastic composite pipe, coated plastic composite steel pipe, steel pipe as the matrix, through spraying, rolling, dipping, suction process in steel pipe (bottom pipe) inner surface of a layer of plastic anticorrosive layer or in the inner and outer surface of the plastic anticorrosive layer of steel-plastic composite steel pipe. Coated steel tube has excellent corrosion resistance and relatively small friction resistance. Epoxy resin coated plastic steel pipe is suitable for water supply and drainage, sea water, warm water, oil, gas and other media transportation, PVC coated plastic steel pipe is suitable for drainage, sea water, oil, gas and other media transportation.

Powder Coated Plastic Steel Tube, Product Features

Powder coated plastic steel tube, Is the use of PE(modified polyethylene) hot-dip plastic or EP(epoxy resin) for internal and external coating products, with excellent corrosion resistance. At the same time, the coating itself also has good electrical insulation and will not produce electrical erosion. Low water absorption, high mechanical strength, small friction coefficient, can achieve the purpose of long-term use. It can also effectively prevent the destruction of plant roots and soil environmental stress. Convenient connection and easy maintenance.

Powder Coated Plastic Steel Tube, Product Advantages

1. Adapt to buried and humid environment, and can withstand high temperature and very low temperature.

2. Strong anti-interference ability. If coated plastic steel tube is used as cable sleeve, it can effectively shield external signal interference.

3. Good pressure strength, maximum pressure up to 6Mpa.

4. Good insulation performance, as a wire protection tube will never happen leakage phenomenon.

5. No burr, smooth pipe wall, suitable for the construction of wire or cable

Powder Coated Plastic Steel Tube, Application Field

1. Various forms of circulating water system (civil circulating water, industrial circulating water), excellent performance, anti-corrosion life up to 50 years.

2. Fire water supply system.

3. Water supply and drainage of each building (especially for cold and hot water systems of guesthouses, hotels and high-end residential areas).

4. All kinds of chemical fluid transport (acid, alkali, salt corrosion).

5. Buried pipe and crossing pipe of wire and cable.

6. Ventilation pipes, supply pipes and drainage pipes of mines and mines
