Coated composite pipes are a new type of environmentally friendly, green piping system. Thanks to their unique properties, they have been the industry’s favorite in the piping sector for over a decade. First, from the perspective of manufacturers, whether it’s plastic pipes, galvanized steel pipes, or any other type of pipe, if there’s no prospect of higher profits, these products tend to be overlooked, forgotten, and eventually abandoned by the manufacturing industry. It is precisely for this reason that only coated composite pipes offer room for agile development. Second, from the customer’s point of view, whether in terms of product characteristics or application functionality, coated composite pipes—compared to plastic pipes and galvanized steel pipes—are more likely to appeal to customers who place great value on both economic and practical benefits.
Plastic-coated composite pipe It is a new type of environmentally friendly, green pipeline. Thanks to its unique performance characteristics, it has been the darling of the pipeline industry for over a decade. First, from the perspective of manufacturers, whether it’s plastic pipes, galvanized steel pipes, or any other type of pipe, if they no longer offer substantial profits, they tend to be overlooked, forgotten, and eventually abandoned by the manufacturing industry. It is precisely for this reason that only coated composite steel pipes have room for agile development. Second, from the customer’s point of view, whether in terms of product characteristics or application functionality, coated composite pipes—compared to plastic pipes and galvanized steel pipes—are more likely to appeal to customers who place great value on both economic and practical benefits.
What are the advantages of coated composite pipes?
1. It can withstand high and low temperatures.
2. Strong anti-interference capability: The composite steel pipe cable jacket can effectively block external signal interference.
3. Pressure-resistant, with a maximum pressure of 6 MPa.
4. The insulation performance is excellent. As an electric wire maintenance worker, there will be no risk of electric leakage.
5. The pipe wall is lubricated, making it suitable for the distribution of wires and cables during construction.
Application scope of coated composite pipes:
1. Various circulating water systems (including domestic and industrial circulating water) feature excellent performance and a corrosion-resistant lifespan of up to 50 years.
2. Firewater supply system
3. Building water supply and drainage systems (especially cold and hot water systems in places such as hotels, guesthouses, and high-end residential areas).
4. Conveying chemical fluid media (resistant to acid, alkali, and salt corrosion).
5. Conduit and crossing pipes for wires and cables.
6. Mines, mine ventilation ducts, and water supply and drainage pipelines.
The coating method for plastic-coated composite pipes is as follows: modified polyethylene (PE)—hot-dip molding, and epoxy resin (EP)—internal and external coatings. This plastic coating offers excellent corrosion resistance, low absorption rate, high mechanical strength, and a low coefficient of friction, enabling the pipe to operate reliably over long periods. Moreover, the coating itself exhibits excellent electrical insulation properties and does not induce electrochemical corrosion. For applications requiring burial in soil, the coated composite steel pipe can effectively prevent stress damage caused by plant root systems and the surrounding soil environment. Another advantage of installation is its rapid connection process and simple maintenance.
Market Analysis of Coated Composite Pipes:
The overcapacity in coated composite pipes has accelerated the marketization of the steel industry, primarily because at that time, the domestic steel market was characterized by a supply shortage, leaving little room for choice in the coated composite steel pipe market. As China’s steel industry has matured, the balance between supply and demand has gradually shifted. If the prices of composite steel pipes remain firm, distributors will suffer substantial losses, and sales channels will face significant setbacks; consequently, it becomes increasingly difficult to paint these composite pipes. Generally speaking, after an initial sharp drop in market prices, the market is likely to experience volatile rebounds in the near term, and prices are expected to rebound somewhat in the near future.
