1 excellent characteristics

Light weight, safe and convenient, good sealing performance and low construction cost
because plastic steel The winding tube has a high stiffness to weight ratio, so it is lighter than any kind Ring stiffness The same pure Plastic pipe
Ring stiffness for safety
Because of the steel plastic two kinds of materials Elastic modulus Therefore, compared with the pure plastic pipe, the steel belt reinforcement can easily make the pipe (especially the large diameter pipe) have enough safety ring stiffness and relatively high stiffness to weight ratio compared with the pure plastic pipe.
Strong resistance to abnormal sudden load
Due to the high stiffness and axial flexibility of the pipe ring, the pipe can pass through when the uneven settlement of soil occurs, the groundwater rises, the local load on the ground is too large, and the sudden load and disaster such as earthquake occur elastic deformation To solve this problem
To avoid leakage or damage of pipe joints due to excessive stress and deformation.
Non toxic
black High density polyethylene (PE) pipeline has passed the inspection of relevant health department and is allowed to use.
The inner surface is smooth
polyethylene (PE) the smooth inner surface of the pipe will reduce the energy loss caused by friction to ¥ *, and it is not easy to deposit in the pipeline. Flow resistance ratio Cement pipe The inner wall of PE pipe with low content of 20-30% is smooth, the friction coefficient is small, and the sediment is not easy to accumulate in the pipeline, so the friction resistance is almost unchanged in the long-term use.
Corrosion resistance, wear resistance, long life
The corrosion resistance of polyethylene (PE) pipeline enables the pipeline to be used to transport corrosive liquids such as acid and alkali, and can be installed in corrosive environment such as swamp and humidity. The chemical corrosion resistance of PE pipeline is shown in the standard ESO / TR 10358.
High density polyethylene The service life of (PE) pipe is more than 4 times that of steel pipe. The installation of polyethylene (PE) pipes can be heated by melting and welding, so as to improve the strength of joints and avoid leakage.
The service life of high density polyethylene (PE) pipe can be as long as 50 years.
Flexibility, no leakage and impact resistance
The good flexibility of polyethylene (PE) pipeline makes it easy to place along the trench terrain, avoid obstacles in the process of laying, and adapt to the soil settlement in swamp area and soft soil area.
No leakage( Electric fusion welding Butt welding )The connection, sealing performance and environmental protection performance of these two sealing connection methods can be operated by hand with simple tools and without machinery, which is very simple and fast, and achieves no leakage
Polyethylene (PE) pipe has high impact resistance, so it will not be broken or damaged during installation and transportation.
UV resistance
The raw materials of polyethylene (PE) pipe have ultraviolet resistance carbon black Therefore, it can be placed outdoors or used outdoors for a long time without worrying about the change of pipeline performance.

two
The inner wall is smooth, Flow resistance than Cement pipe 20-30% lower
The inner wall of PE pipe is smooth, friction coefficient It is small, and the sediment is not easy to accumulate in the pipeline, and the friction resistance is almost unchanged after long-term use
three
Flexible or leak free( Electric fusion welding Butt welding )Good connection, good sealing performance and environmental protection performance
The two sealing connection methods can be operated by hand with simple tools and without machinery, which is very simple and fast, and achieves no leakage
four
Corrosion resistant, service life over 50 years
The service life of high density polyethylene (PE) pipe can be as long as 50 years
five
Light weight, less joints, no need for large equipment, easy installation and laying
It is light in weight and does not need large lifting equipment during installation. Good axial flexibility, low requirements for smoothness and firmness of groove bottom during laying, and strong ability to withstand abnormal stress caused by improper installation
six
Strong resistance to abnormal sudden load
Pipe can pass through elastic deformation To resolve the resulting stress and avoid leakage or damage of pipe joints due to excessive stress and deformation
seven
The comprehensive cost is competitive
Combining the advantages of steel and plastic materials, the pipe has the comprehensive properties of.

4 connection

Clamp type elastic connection

The connection requires that at least two welded plastic sealing blocks shall be provided in the inner sealing area of the spiral groove at the connection part of the pipe end Stiffener The same height. The connection structure is composed of three layers, the inner layer of * * is a thin-walled rubber sleeve, and the tight sleeve plays a sealing role at the pipe end; The middle layer is a certain thickness of foam rubber plate with good elasticity, which plays a filling role. Through its deformation, the hoop pressure of the outer stainless steel looper can be evenly transferred to the inner sealing rubber plate, so as to eliminate the influence of pipe end surface unevenness, rib height unevenness and ellipse on sealing performance; The outer layer is an open stainless steel looper. The tightening force of the looper to the inner rubber sleeve can be adjusted by the fastening bolt on the looper to ensure the sealing. Meanwhile, the stainless steel is adopted Looper It can be used to connect the pipe Ring stiffness The compensation effect of**** Stainless steel card The hoop and pipe have the same service life, and the secondary anti-corrosion processing is carried out
The connection of stainless steel hoop is a connection method which uses mechanical fastening method to connect two adjacent pipe ends into one. The connection structure is composed of three layers, the * * inner layer is thin-walled rubber sleeve, and the tight sleeve plays a sealing role at the pipe end; The middle layer is a certain thickness of elastic foam rubber plate, which plays a filling role, and the outer layer is stainless steel hoop. Through the tightening force of the fastening bolt on the stainless steel hoop, the inner rubber sleeve is pressed to achieve sealing effect and foaming Rubber plate The main function of the stainless steel hoop is to transfer the pressure of the stainless steel hoop evenly to the inner sealing rubber plate, so as to eliminate the influence of the pipe end surface unevenness, rib height unevenness and Ovality on the sealing performance. This connection method is suitable for pipe diameter DN ≤ 1200mm Plastic steel winding pipe
