Hainan steel mesh skeleton pipe
Strong resistance to external pressure
The outer wall is annular corrugated structure, which greatly enhances the ring stiffness of the pipe, thus enhancing the resistance of the pipe to soil load. In this performance, HDPE double wall corrugated pipe has obvious advantages over other pipes.
Low project cost
Under the condition of the same load, HDPE double wall corrugated pipe can meet the requirements only with a thinner pipe wall. Therefore, compared with solid wall pipes of the same material specification, it can save about half of the raw materials, so the cost of HDPE double wall corrugated pipe is also low. This is another outstanding feature of the pipe.
Convenient construction
Due to the light weight of HDPE double wall corrugated pipe and the convenience of handling and connection, the construction is fast and the maintenance is simple. In case of tight schedule and construction
Under poor conditions, its advantages are more obvious.
Small friction coefficient and large flow
HDPE double wall corrugated pipe made of HDPE can pass through a larger flow than other pipes of the same caliber. In other words, HDPE double wall corrugated pipe with relatively small diameter can be used under the same flow requirements.
Low temperature resistance and impact resistance
The embrittlement temperature of HDPE double wall corrugated pipe is - 70 ℃. It is not necessary to take special protective measures during construction under general low temperature conditions (above - 30 ℃). It is convenient to construct in winter, and HDPE double wall corrugated pipe has good impact resistance.
Good chemical stability
Since HDPE molecule has no polarity, its chemical stability is excellent. Except for a few strong oxidants, most chemical media will not destroy them. Generally, soil, electricity, acid and alkali factors in the service environment will not damage the pipeline, breed bacteria, scale, and its flow area will not decrease with the increase of operation time.
Long service life
The service life of HDPE double wall corrugated pipe can reach more than 50 years under the condition of not being exposed to sunlight and ultraviolet rays.
Excellent wear resistance
Germany once used tests to prove that the wear resistance of HDPE is even several times higher than that of steel pipes.
Proper deflection
A certain length of HDPE double wall corrugated pipe can be slightly flexed axially, free from the influence of uneven settlement of the ground to a certain extent, and can be directly laid in a slightly uneven groove without pipe fittings.
