Tianjin Juming Steel Pipe Co., Ltd. specializes in the production of plastic coated water supply pipes. The product uses high-quality Q235B welded steel pipes or seamless steel pipes as the base material. Through processes such as sandblasting rust removal, preheating, electrostatic spraying, and high-temperature curing, the inner and outer walls are coated with food-grade epoxy resin (EP) or modified polyethylene (PE) powder coatings to form a high-performance composite pipe.
Plastic Coated Water Supply Pipe | High Strength & Corrosion Resistance
High strength of steel · Corrosion resistance & hygiene · Smooth flow · For municipal, industrial & overseas projects

Product Advantages
Hygienic and non-toxic
Food-grade coating with no heavy metal release. No scaling and no bacterial growth, suitable for potable water systems.
Strong corrosion resistance
Resistant to acids, alkalis, salt spray, and soil corrosion. Suitable for underground and coastal environments with a service life of up to 50 years.
Efficient water flow
Smooth inner wall reduces friction resistance, resulting in lower energy consumption and higher flow capacity.
High strength and durability
Steel base provides strong mechanical strength, excellent pressure and impact resistance, and is not easily deformed during construction.
Easy installation
Supports multiple connection methods including threaded, grooved, flanged, and welded connections.
Application Scenarios
Municipal engineering: Urban water supply trunk pipelines, residential water networks, underground water transmission
Building engineering: Hot and cold water supply for high-rise buildings, commercial buildings, hospitals, and schools
Overseas special projects: Island desalination, desert water transfer, ports, shipbuilding, mining drainage systems
Real Project Case
Southeast Asia Municipal Water Supply Project
Project overview: In 2025, we supplied Plastic Coated Water Supply Pipes for a municipal water supply renovation project in a Southeast Asian city. The system covered urban districts and surrounding towns with a total supply of over 800 tons of DN800 internal and external epoxy coated steel pipes.
Project requirements: The system needed to withstand long-term coastal high-salt environments, maintain stable pressure performance, ensure water safety, prevent secondary contamination, and reduce leakage rates.
Results: Since installation and operation, the pipeline has shown no leakage or corrosion. Third-party inspection confirmed no internal scaling and intact coating condition. The network leakage rate dropped from 22% to below 5%. The system fully met local drinking water standards, passed final acceptance, and gained high recognition from the project owner, leading to long-term supply cooperation.
