The pipe ensures hygiene and safety, eliminating secondary contamination and posing no adverse effects on human health. The hygiene indicators strictly adhere to the national standard. It is also impact-resistant and can bend to 10° (with a curvature radius being eight times its outer diameter); when pressed to 3/4 of its external diameter, the steel pipe and the inner plastic lining remain intact without separation.
Using specialized hot-melt adhesive, the bond strength after compositing significantly surpasses the industry standard requirements.When connecting the pipe material with fittings, besides sealing the threads with sealant or polytetrafluoroethylene raw tape, the pipe end surface and the rubber pad inside the plastic-lined fittings are sealed again, ensuring complete isolation between metal and water.
The pipe is produced using the most advanced domestic steel-plastic composite production line, ensuring the composite’s quality and stability.The working pressure of the pipe is ≤1.6MPa, the long-term use temperature should not be higher than 70°C, and the short-term use temperature should not be higher than 95°C. Pipe length is usually 6 meters.

PE-lined Steel-Plastic Composite Pipes Advantages
Composed of polyethylene or epoxy resin powder, the plastic layer is non-toxic and tasteless. It doesn’t contaminate the water, fully meeting the national standards for domestic water conduit pipes and doesn’t contaminate the water passing through it. It perfectly meets the standards for domestic water conduit pipes.
The plastic-coated compound steel pipe features a highly adhesive inner plastic layer with excellent compactness and corrosion resistance. This substantially extends the lifespan of the pipe. While the galvanized coating generally offers effective corrosion resistance, the plastic-coated compound steel pipe performs even better in harsh environments, such as those with acidic conditions.
The plastic-coated compound steel pipe possesses a mechanical strength on par with that of a hot-dip galvanized steel pipe. This makes it capable of withstanding external factors like impact, bending, and pressure.It can be used in various applications including domestic water supply, industrial fluid transportation, and specialized environments with corrosive media.
Thanks to its smooth inner wall and low friction, the plastic-coated compound steel pipe for water supply is resistant to scale build-up and has minimal fluid resistance, ensuring unimpeded water flow.These pipes have a lower environmental impact compared to traditional steel pipes as they require less energy to produce and can be recycled.
Product Application Scope and Uses
The plastic-coated compound steel pipe has a wide range of applications, notably in civil and industrial water supply, fire protection systems, sewage transport, telecommunications networks, optical fiber cables, and coal gas transport. Furthermore, it’s highly suitable for use in food processing, pharmaceutical, and machinery industries. Above all, it’s an excellent product choice for urban water supply systems. Application Fields such as below:
- Residential water supply projects: Municipal water supply pipeline systems, and water supply systems for residential and commercial buildings.
- Industrial piping systems: Used for industrial water supply pipeline systems, gas pipelines, air conditioning systems, automatic fire extinguishing systems.
- Chemical pipeline systems: Used for transporting various chemical mediums, corrosive mediums, etc.
- Others: Other uses include food processing, pharmaceuticals, pure water treatment, medical applications, deionized water, etc.
Innovating Piping Solutions: The Rise of Steel-Plastic Composite Pipes
Steel-plastic hybrid pipes represent a recent innovation in China’s piping industry. These pipes, originating from a steel core, are lined internally with various types of plastics. Marrying the strengths of both steel and plastic, these composite pipes boast the robustness and sturdiness of steel, while also enjoying the benefits of plastics, such as resistance to chemical corrosion, contamination-free nature, sleek internal surfaces, minimal scaling, and reduced fluid resistance. As the construction sector flourishes, so does the demand for steel-plastic hybrid pipes. Their prominence in the domestic market is on the rise, positioning them as a go-to choice for modern water supply solutions.
Innovating Piping Solutions: The Rise of Steel-Plastic Coated Composite Pipes
Plastic-coated steel composite pipes utilize galvanized steel pipes or phosphatized steel pipes as their base. Through advanced processes, the inner (or outer) walls are sprayed, adsorbed, and melted with PE/EP powder coatings, followed by high-temperature curing. This results in a composite pipe material that is non-toxic, tasteless, smooth, clean, scale-resistant, with a low water flow friction coefficient. Additionally, it possesses the hardness and toughness inherent to steel pipes.
Product Overview and Business Terms
Plastic-coated steel-plastic composite pipe uses galvanized steel pipe or phosphating steel pipe as the matrix, and is a composite pipe material that is sprayed, adsorbed, melted PE/EP powder on the inner (outer) wall with advanced technology and cured at high temperature without coating. It is a non-toxic, odorless, smooth, clean, non-scaling, low friction coefficient of water flow, and has the hardness and toughness of steel composite pipe.
