Plastic coated steel pipe

The plastic coated steel pipe is mainly the planned plastic lining, which can improve its corrosion resistance, and the coating has strong adhesion to the steel pipe. The important point is that the coating will not have any impact on the fluid medium. Other, all steel pipes have no compliance point in planning, but have strong deformation capacity. This makes the product have strong pressure resistance when used. Separately, the outer circle of the male end of the steel pipe has a sealing cone connected with the sealing ring, an annular boss positioned with the elastic steel ring, a flange plan for placing the connecting hand pressure ring, and the inner cavity of the female end has an annular groove for placing the sealing ring and an annular positioning groove for placing the elastic steel ring. The outer circle has a groove plan for placing the connecting hand pressure ring, which can enable the plastic coated steel pipe to be connected and constructed in flammable and explosive environments. Therefore, this kind of plastic coated steel pipe is used everywhere in our days. Plastic coated steel pipe is made of plastic and steel, but its compressive strength has not been weakened, and it has been strengthened to a certain extent. Now, the use of plastic coated steel pipe with high pressure resistance up to 6Mpa is very common in our construction industry, mainly because this kind of steel pipe has certain characteristics. First of all, it is mainly produced by steel pipes and tubes as the basic body, and it is manufactured by specialized personnel through technical research and development. In the practical connection, the lining plastic material must be connected with the flange end face, and ensure that the internal fluid is completely blocked from the steel pipe, so as to achieve safety and reliability. Flange connection can be applied to various pressure pipeline equipment.

Plastic coated steel pipe, also known as plastic coated pipe, steel plastic composite pipe and plastic coated composite steel pipe, is a steel plastic composite steel pipe with the steel pipe as the base, which is welded with a plastic anti-corrosion layer on the inner surface of the steel pipe (bottom pipe) or welded with a plastic anti-corrosion layer on the inner and outer surfaces through spraying, rolling, dipping and suction processes.

Plastic coated steel pipe has excellent corrosion resistance and relatively small friction resistance. Epoxy resin coated steel pipes are suitable for the transmission of water supply and drainage, seawater, warm water, oil, gas and other media, while PVC coated steel pipes are suitable for the transmission of drainage, seawater, oil, gas and other media.
