1. Excellent corrosion resistance
- The inner and outer coating effectively isolates the contact between the steel pipe and the external environment, prevents the erosion of chemical substances, and prolongs the service life of the pipeline.

- Suitable for all kinds of harsh corrosive environments, such as chemical, marine and other fields.

2. High strength and durability
- The steel tube matrix provides strong support and is able to withstand high compressive and tensile forces.

- Sturdy and durable, not easy to deform, to ensure long-term stable operation.

3. The inner wall is smooth and the fluid resistance is small
- Reduce energy loss in the conveying process and improve conveying efficiency.

- Reduced maintenance costs and reduced risk of pipe clogging.

4. Hygienic and environmentally friendly
- The coating material meets hygienic standards, is non-toxic, odorless, and does not breed bacteria.

- Ensure the cleanliness and safety of the conveying medium, suitable for drinking water and other fields with high hygiene requirements.

5. Aesthetically pleasing appearance
- The surface coating has uniform color and luster, which is beautiful and generous, and enhances the overall image of the project.

 

1. Urban water supply and drainage
- Provide safe and stable water supply to city dwellers while ensuring the smooth operation of drainage systems.

2. Fire protection system
- In the event of a fire, reliable fire pipes can quickly deliver fire extinguishing water to ensure the safety of life and property.

3. Petrochemical industry
- Withstand the corrosion of chemical media to ensure the safety and efficiency of material transportation.

4. Construction works

Plastic-coated steel pipe is a new type of composite pipe that is evenly coated with a layer of plastic anti-corrosion layer on the inner and outer surfaces of steel pipes.
It combines the high strength of steel pipes with the corrosion resistance, wear resistance and other characteristics of plastics for various projects
It provides a reliable pipeline transportation guarantee.

Trench connection:
Grooved connections are commonly used in plastic-coated pipes, with flexible connections and simple operation. Before the base tube is coated, the base tube is grooved according to the customer's order requirements, and then the base tube is coated with plastic. The groove pressing standard needs to comply with the CECS151: 2003 China Engineering Construction Standardization Association Standard "Technical Code for Grooved Connection Pipeline Engineering".

 

Mine-use plastic-coated steel pipe: It is a steel-plastic composite pipe with antistatic and flame retardant properties made by coating a special polyethylene material on the inner and outer surface of the steel pipe by applying a special polyethylene material to the welded steel pipe or seamless steel pipe as the base pipe.
Plastic-coated steel pipe is a product that is coated internally and externally with PE (modified polyethylene) hot-dip plastic or EP (epoxy resin), and has excellent corrosion resistance. At the same time, the coating itself has good electrical insulation and does not produce electrical corrosion. Low water absorption, high mechanical strength, low friction coefficient, can achieve the purpose of long-term use. It can also effectively prevent the destruction of plant roots and soil environmental stress. Easy to connect and easy to maintain.
Mine plastic-coated composite pipe is a general pipe in coal mines, which can be used for water supply and drainage, positive pressure ventilation, negative pressure ventilation, spraying and gas pumping in underground coal mines, and shall not be used for other purposes, and the use pressure shall not exceed the nominal pressure.

 

Plastic-coated steel pipe for gas: With the successive introduction of new pipelines, the pipeline used for transporting gas adopts plastic-coated pipe, and the internal and external plastic-coated pipe is a special gas pipeline, which can transport any gas, including: natural gas, gas, biogas, gas, etc., which is a multi-functional pipeline.

 

Socket Connections:
Socket connection, also known as flaring connection. It is to change the sealing connection structure of the pipeline connector to fundamentally solve the problem of water seepage in the pipeline connection, and the flaring connection ensures the sealing connection between the pipe connector and the plastic-coated steel pipe. The construction operation is simple and convenient, and it is mainly used for threading pipelines.

 

Flange connection:
The flange connection has good strength and sealing, simple structure, low cost, and can be disassembled repeatedly. Before the base pipe is plasticized, it is necessary to weld the flange to the base pipe, and then the flange pipe is plasticized.

Thread connection:
In wire processing, it is necessary to strictly ensure that the screw length, tooth shape, tooth height, and other parameters meet the relevant standard process requirements. Before using the wire connection, the appropriate filler should be added to the outer thread of the connection or in the pipe fitting to seal and protect.
Wire first, then coat!
