(HDPE) double-wall corrugated pipe

High-density polyethylene (HDPE) double-wall corrugated pipe, a new type of pipe with a ring-like structure of the outer wall and smooth inner wall, was first developed successfully in Germany in the early 80s. After more than ten years of development and improvement, it has developed from a single variety to a complete product line. At present, the production process and use of technology has been very mature. Due to its excellent performance and relatively economic cost, it has been greatly promoted and applied in Europe and America and other developed countries. Double-wall corrugated pipe inner wall color usually has blue and black, some brands will use yellow inner wall.

Features

High-density polyethylene (HDPE) has excellent chemical stability, aging resistance and resistance to environmental stress cracking. HDPE double-wall corrugated pipe produced from its raw materials is a flexible pipe. Its key properties are as follows:

Strong resistance to external pressure

The outer wall is in the shape of a ring corrugated structure, which greatly enhances the ring stiffness of the pipe, thus enhancing the resistance of the pipe to soil load.

Low engineering cost

Under the same load conditions, HDPE double-wall corrugated pipe only needs a thin wall to meet the requirements. Therefore, it can save about half of the raw material compared with the solid wall pipe of the same material specification, so the cost of HDPE double wall corrugated pipe is also lower. This is another outstanding feature of this pipe.

Convenient construction

Since HDPE double-wall corrugated pipe is light in weight, it is easy to carry and connect, so the construction is fast and maintenance is simple. In the case of tight schedule and poor construction
The advantages are more obvious under the condition of poor construction.

Small friction coefficient, high flow rate

HDPE double-wall corrugated pipe made of HDPE can pass a larger flow rate than other pipes of the same diameter. In other words, under the same flow requirements, HDPE double-wall corrugated pipe of relatively small caliber can be used.

Low temperature resistance and impact resistance

The embrittlement temperature of HDPE double-wall corrugated pipe is -70℃. It is not necessary to take special protection measures when constructing under general low temperature conditions (-30℃ or above), and it is convenient to construct in winter, moreover, HDPE double-wall corrugated pipe has good impact resistance.

Good chemical stability

Because HDPE molecules have no polarity, so the chemical stability is excellent. In addition to a few strong oxidizing agents, most chemical media do not have a destructive effect on it. General use of the environment of the soil, electricity, acid and alkali factors will not damage the pipe, does not breed bacteria, does not scale, and its circulation area will not be reduced with the increase in operating time.

Long service life

The service life of HDPE double-wall corrugated pipe can be more than 50 years under the condition of no ultraviolet sunlight.

Excellent wear resistance

Tests have proven that HDPE’s abrasion resistance is even several times higher than that of steel pipes.

Proper Flexibility

A certain length of HDPE double-wall corrugated pipe axially can be slightly deflected, not affected by a certain degree of uneven ground settlement, can be laid directly in a slightly straight trench without fittings, etc.
