Characteristics

Because of the reasonable design and the advanced production technology, the Metal reinforced polyethylene(PE)spirally corrugated pipe possesses many advantages, such as high ring stiffness, resistance to corrosion and abrasion, light weight, convenient construction and installation etc..

It is a new kind of pollution-free plastic pipe which recommended by the Ministry of Construction. The features follows:

1 For the high elastic modulus of corrugated steel strip, the pipe possesses high ring stiffness.

Metal reinforced polyethylene(PE)spirally corrugated pipe makes use of the special corrugated steel as supporting structure. Because of steel’s high elastic modulus and pipe cross-section’s high moment of inertia, there are 4 ring stiffness classes for the pipe: SN8, SN10, SN12.5, and SN16. Its high ring stiffness breaks the limit that the highest ring stiffness of plastic pipe can only reach the SN8. It makes plastic pipe can satisfy various engineering requirements.

2 The HDPE materials is very stable is chemical reaction, the pipe can resist corrosion and abrasion, and has a long service life.

The steel is completely covered by HDPE, so only the HDPE is exposed to the liquid and the soil. HDPE is a kind of crystal Non-polar material, it is very stable and has no electric-corrosion. Pipe resists corrosion and abrasion, has a long service life.

3 Smooth inter wall, the transportation capability of the pipe is high

The inner wall surface of Metal reinforced polyethylene(PE)spirally corrugated pipe is smoother than concrete pipe. So the transportation capability of the pipe is obviously higher than that of concrete pipe under the same condition.

4 Hollow structure, light weight, convenient construction and installation

With the corrugated steel strip as supporting structure, it needs fewer raw materials than other plastic pipes. Metal reinforced polyethylene(PE)spirally corrugated pipe is light. It can be connected by many kinds of method, for example, electric melting belt; the transport and installation are convenient and simple.

5  HDPE and adhesive resin are combined with the steel strip closely in molten state.

As bond between HDPE and steel, there is a layer of adhesive resin which the steel strip’s surface coats with. To control the optimum temperature, pressure and time can ensure that HDPE and steel compound closely. It prevents the steel strip being rusty.

6 Flexible pipe, joint steady, resist to unequal settlement

Metal reinforced polyethylene(PE)spirally corrugated pipe possesses the characteristic of both rigidity and flexibility, when under pressure, the pipe and backfill soil can resist to external load and reasonable uneven settlements of soil.

Combined with the advantages of the electric-melting belt welding method and the patented technology of welding, it can ensure the welding quality be safety.

Q:What is the difference between steel plastic composite pipe and lining plastic pipe? How much is the price difference?
Steel plastic composite pipe, plastic and plastic lining, now the market is above the common plastic coated epoxy resin, he is epoxy powder by electrostatic adsorption in the wall above and then through high temperature welding. Plastic lining is relatively simple, but the lining pipe is divided into cold water type and hot water type. The price difference between the two products is relatively large, if you need to use this, it should see what you are using in the system, and some can not just look at the price, there will be big things! I am Jiangsu Sanhui Lianfa pipe industry, are interested can exchange! Hope to be of help to you
Q:PSP steel plastic composite pipe transition, according to the head can directly melt with PPR
The PP-R/PE welding machine (1200W, 260 degrees C) is selected, and the surface of the hot melt die, the transition joint and the pipe surface are cleaned, and the temperature is up to 260 degrees C (green indicator light);
Q:What's the difference between steel wire mesh plastic composite pipe and steel skeleton composite pipe?
Comparison of composite structures for tube manufacturing:The steel mesh skeleton plastic composite pipe, with high strength steel wire should be (above 1950Mpa) as the substrate, take two times the combined form, with a 54.7 degree oblique wire wound on the pipe, the pipe under internal pressure to the axial and circumferential uniform dispersion force, a higher safety factor used in determining the wire the diameter and density.The welding of steel skeleton plastic composite pipe, ordinary carbon steel wire for steel wire substrate, although thicker, but the tensile strength is 400Mpa, complex process, product quality fluctuation.
Q:What kind of industry are metal composite pipes used in?
Civilian field:Cold and hot water pipe, straight drinking water pipe, heating, solar energy and ground source heat pump; civil building water supply pipe, water distribution dry pipe, air conditioning circulation pipe, refined decoration, high-grade commodity house, water supply pipe and so on.
Q:What is called PSP steel plastic composite pressure pipe, the connection mode or the expansion type?! The big caliber is the flaring joint!
Performance characteristics:Good mechanical strength, high compressive strength and stable performance;The coefficient of linear expansion is small and it is not deformed;Excellent corrosion resistance, to prevent external corrosion, internal corrosion, to ensure that the service life of 50 years;The inner wall is smooth and the resistance coefficient is small;New double hot melt connection - safer and more economical
Q:Can aluminum plastic pipes be used for drinking water?
Common drinking water aluminum plastic composite pipe: white L mark, applicable scope: domestic water, condensed water, oxygen, compressed air and other chemical liquid pipeline.
Q:Aluminum alloy lined plastic composite pipe which is divided into several?
The aluminium alloy lining pipe for water supply is divided into 3 kinds:Aluminum alloy lined plastic PE-RT composite pipe; aluminum alloy lined plastic PPR composite pipe; aluminum alloy lined plastic Pb composite pipeAluminium alloy lining plastic composite pipe for gasAluminum Alloy PE plastic lining composite pipe
Q:There are several kinds of plastic steel composite pipe, what is the connection mode?
Steel plastic composite pipe is divided into two kinds of plastic and plastic lining, if the design is lined with plastic coated steel pipe can be used instead, but if the design is not available to replace the plastic lining plastic pipe.
Q:What are the components of the CEMS composite sample tube?
Heat tracing: self regulating power, automatic compensation, accompanied by heat insulation, high efficiency insulation;Electric control: can be equipped with instrument signal cable, compensation and control cables meet the monitoring instrument display, create conditions for computer centralized control; fire safety, leakage protection, anti-static, electromagnetic shielding effect.
Q:PSP plastic steel composite pipe and lining plastic composite pipe can be used instead?
The steel plastic composite pressure pipe is a new type of composite pipe made of metal and plastic. The welded steel pipe is used as the middle layer, the inner and outer layers are polyethylene plastics, and the special hot melt adhesive is used to form a pipe through the extrusion forming method.
