Metal reinforced polyethylene(PE)spirally corrugated pipe

Product Description

A. Product introduction

Metal reinforced polyethylene（PE）spirally corrugated pipe is a new kind of double walled spirally corrugated pipe. It uses the HDPE as basic material, and the steel strap spiraled as the supporting part, which is spiraled to corrugated wall structure.

B. Characteristics

Because of the reasonable structural design and the advanced production technology, 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 are as 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, SN*0, SN*2.5, and SN*6. 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.
