The advantages of fire-fighting steel-plastic composite pipes are: excellent corrosion resistance, low resistance coefficient of fire-fighting steel-plastic composite pipes-the inner and outer layers of polyethylene of the steel-plastic composite sheath are a non-polar material with stable chemical properties. Can withstand the corrosion of various acids, alkalis and salt solutions; good shielding performance-good shielding effect on electromagnetic waves, anti-interference; excellent mechanical strength, high compressive strength, stable performance; good impact resistance and high safety; Self-display tracking-magnetic metal detectors can be used for tracking, no additional tracking or protection marks are needed, which can avoid excavation damage and provide convenience for repair and maintenance; easy installation, long service life, composite pipes, steel-plastic composite pipes What are the advantages up to 50 years.

PSP steel-plastic composite pipe application scope: construction engineering is suitable for public buildings and residential water supply pipelines; municipal engineering is suitable for urban water supply pipeline systems and gas transmission systems; industrial fields can be widely used in petroleum, chemical, pharmaceutical, food, mining and other fields.

Everyone carefully observes and analyzes the steel-plastic pipe market, and it can be seen that it is booming. Many problems should be paid attention to in the use of internal and external steel-plastic pipes. All plastic-coated pipes have been well inspected and tested when they leave the factory, so as to ensure the use of customers and ensure that customers can buy our products again. . There is a lot of room for the development of plastic-coated pipes in our country, and now is a great time to accelerate the development and expand the market share. The development of internal and external plastic-coated steel pipes benefited from the excellent chemical stability of its epoxy cured products. It is resistant to alkali, acid, salt and other media. The corrosion function is superior to thermosetting resins such as unsaturated polyester resins and phenolic resins. The cured epoxy resin has a three-dimensional network structure. It has no special requirements for transportation.
