With the continuous emergence of new pipelines in recent years, the plastic pipe has been used to transport gas. Plastic pipes are special gas pipelines that can transport various gas such as natural gas and biogas, which are multi -functional pipelines.

The scope of application of plastic steel pipes is wide. The steel pipes treated with chemicals in the internal and external layers are the scope of coating steel pipes. Plastic chemicals commonly used in the outer layer of steel pipes include polyethylene, epoxy resin and other coatings. The service life of plastic steel pipes is longer than the previous tubes, which can be used for 50 years. However, the steel pipe changes the characteristics of the original tube after coating, so you must pay attention when laying.

Features of plastic steel pipes: have the characteristics of anti -corrosion and rust. The inner wall of the anticorrosive spiral steel pipe of the epoxy resin coating is very smooth and the friction resistance is small. Can be used for natural gas pipelines or drinking water pipes. Moreover, the outer wall of the pipeline can be brushed with bright paintings, which is also more beautiful.

Compared with traditional crispy and rusty pipes, the service life of plastic steel pipes can reach more than 50 years, and the total cost is quite low. Compared with copper pipes and galvanized pipes, it is more cost -effective. So now it's not just a water supply pipe at home. In addition, it is also the municipal pipeline of the city. For example, as a natural gas and oil pipeline, coating steel pipes have the hardness of the previous steel pipe, and it is lighter, the resistance is small, and the flow rate in the pipeline is faster.

Product characteristics: Mine -shaped plastic pipes (hereinafter referred to as film -covered plastic steel pipes) are steel -plastic composite pipes with anti -static and flame retardant properties. They are made through process treatment and specially coated with special polyethylene materials on the inner and outer surface of ordinary steel pipes. Essence

(1) This product uses polyethylene coatings. Its anti -static and flame retardant ingredients are evenly distributed on the surface and inner layers of the pipeline. It meets the requirements of MT181 and is suitable for specific places where mines are flammable and explosive.

(2) Extremely strong adhesion: After coating the steel pipes, after coating, adhesion, and maintenance, the inner and ourselves surface adhesion Greater than or equal to 30n/10mm, and the menstrual hammer is impacted and no damage after tearing.

(3) Corrosion resistance, not easy to scalce, and small fluid resistance: pipelines are strong and alkaline, suitable for mining high sulfur water quality, calcium and magnesium ion water. Due to its high surface cleanliness, low fluid resistance, and no dirt, it can reduce secondary pollution.

(4) High -voltage bearing capacity: Polyethylene powder has good plastic coating toughness, high steel pipe mechanical strength, strong anti -impact, bending and other external effects.
