Performance features:
1. High pressure bearing and good mechanical performance: keeping the advantages of steel pipe, with high mechanical strength, and strong bearing capacity for external impacts such as impact bending.
2. Strong chemical corrosion resistance: having the advantages of plastic pipes, the plastic coating has strong chemical corrosion resistance. The products can be coated with flanges, and all kinds of Pipe Fittings receive the anti-corrosion treatment on internal and external coatings to ensure the anti-corrosion effect of the whole pipeline.
3. Strong adhesion of coating: through pretreatment by special process, the grade reaches Sa2.5 before plastic coating. The quality of the coating is ensured by scientific and reasonable technology and advanced production equipment.
4. Low fluid resistance due to no scaling: the inner surface coating is precision and non-scaling, thus the friction coefficient and the roughness coefficient are smaller comparing with ordinary steel pipes. The roughness coefficient is equal to that of the plastic pipes, i.e. 0.01.
5. Various connection methods, convenient for installation: the products can be connected by various methods, including flange, clamp, bi-metal connection, and butt welding, which is convenient for installation.
6. The internal and external coatings can be coated with different coating materials and colors according to customer requirements: the main coating methods include internal and external PE powder coatings, internal and external epoxy resin powder coatings, as well as internal PE powder coating and external epoxy resin powder coating. The color can be replaced according to customer needs.
Specification: the specification of coated steel composite pipe for water supply needs to meet the requirements in the table below.
