40mm 3.5mm Steel Reinforced Plastic Pipe For Water Supply Pipeline System

Product Specification

Grade:Hot Water

Product:With The Inner Stainless steel Ring Plastic-Steel Composite Panel for Hot Water

Decriptions

Steel and plastic pipe pipe outlet are equipped with a unique brand "inner ring" single product, the inner ring material is 304 stainless steel, won the national patent product (patent no.: ZL 2016 3 0491414.9); complete specifications, has the current large and small caliber DN15-DN400 production capacity that cannot be delivered in the same industry. The inner fixed ring can completely solve the problems of hose cracking and peeling caused by long-term water pressure impact at the pipe mouth; 4. Production efficiency and production capacity are 3 to 5 times that of general enterprises, and the proportion of technical workers used only accounts for 1 / 2-1 / 4.

With the inner stainless steel ring plastic-steel composite panel is combination with PEX pipe and Hot dip galvanized steel pipe and the inner stainless steel ring. It is used by constant pressure and high temperature composite technology,ensure the inner plastic pipe in good shape and bonding the steel pipe well,without glue cracking and shrinking issues happening. The hot DIP galvanized steel pipe is adopt the international leading high-frequency new welding technology,and galvanized with high quality 0 pure Zinc plating. The plastic pipe is used by high quality and 100% virgin PE,which meets the standards of food hygiene and drinking water.The hot melt adhesive resins are good quality,high purity with excellent bonding strength,ensure the bonding strength between the steel pipe and plastic pipe. The plastic-steel composite pipe head is fixed the inner 304 stainless steel ring,which is national patent products. The inner stainless steel ring perfect resolves the separated problems between the plastic pipe and steel pipe,for which the expansion and contraction happens, or the flow water impacting the pipe head for long time. The revolutionary technology can protect the water quality well,meanwhile elongates the pipe service life greatly and makes price competition. The big size pipes form DN-200 to DN400 are used by same technology as small size pipes, which is hard to achieve by most of other companies.

Physical Properties

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.
