Application
 
Water supply pipe system for domestic water,drinking water and projects,other relevant fields.
 
Advantages
 
1. High mechanical strength. The inner solid ring steel-plastic composite pipe has the same excellent mechanical strength as the hot-dip galvanized steel pipe. It has strong resistance to impact, bending and pressure, and the operating pressure range is less than or equal to 1.6Mpa.
2. Anti-corrosion and long service life. The conveying fluid is effectively isolated from the metal, only in contact with the plastic layer, and has a good anti-corrosion effect, which greatly prolongs the service life of the pipeline, and can be used for 70 years under normal conditions.
3. The fluid resistance is small. The inner wall of the steel-plastic composite pipe with inner solid ring is smooth, the friction coefficient is small, the flow rate is fast, no scale is accumulated, and the fluid resistance is small.
4. Good hygiene performance. The lined plastic pipe is made of food-grade plastic, brand-virgin PEX, which will not pollute the conveyed medium, the inner wall is smooth, free of scale and rust, ensuring that the water quality and sanitation indicators meet the domestic water transmission and distribution standards, and the quality reaches international quality level.
5. Plastic and steel pipe are well compounded. Strong adhesion, not easy to fall off, good sealing performance, no pinholes or cracks to ensure no leakage.
6. The plastic layer has good performance. Low thermal conductivity, environmental protection and energy saving, good low temperature brittleness, and small expansion coefficient.
7. Simple installation. The traditional installation process, and the use of matching pipe fittings with strong sealing energy absorption, the connection is reliable, simple and fast. The pipeline is easy to maintain and the maintenance cost is low.
8. The main equipment is self-developed and has the characteristics and professional technology that ordinary enterprises cannot imitate. The production efficiency and production capacity are 3-5 times that of general enterprises. The lead time required by customers can be ensured.

Installation and connection Method

 
1. Groove connection
a. Select a Standard-Compliant Grooved Fitting;

b. The working pressure of the grooved pipe joint should match the working pressure of the pipeline;

c. Select the rubber sealing ring of the composite drinking water standard, and the hot water pipe adopts the temperature-resistant rubber sealing ring.

2. Threaded connection

a. Choose the Threaded Fitting that meets the requirements;

b. The plastic-lined pipe shall not be directly connected with the valve, and a special transition pipe joint with internal and external threads of brass lined with plastic shall be used;

c. The plastic-lined pipe shall not be directly connected with the water supply spigot, and a special brass inner thread pipe joint shall be used;

d. Special transition joints should be used when connecting plastic-lined pipes with copper pipes and plastic pipes;

3.Flange connection

a. When the working pressure of the pipeline system is greater than 1.0Mpa and less than 2.5Mpa, flange connection can be used;

b. The pressure level of the flange matches the working pressure of the pipeline;

c. Rubber gaskets are used for flange gaskets. When large-diameter gaskets need to be spliced, they should use oblique lap joints, and no flat joints.
