HDPE Drainage Pipe Price List

The material of polyethylene double-wall corrugated pipe is very strong, durable and stable. Compared with other materials, this double-wall corrugated pipe is less likely to crack. Moreover, compared with concrete pipes and cast iron pipes, the purchase cost of polyethylene double-wall corrugated pipe is lower, and it is not complicated to use and install, and the construction process is very simple.

Product level

HDPE culvert pipe wall thickness level: Double-wall corrugated pipes can be divided into four levels according to the company, namely S1, S2, S3, S4, etc. According to the national standard, SN4 and SN8 are divided. The levels used in different scenes are different. They are generally ranked as follows: S1≥4 kn/s3, S2≥8kn/m2, s3≥16 kn/s, for example: S2-500 refers to the SN8 type with a diameter of 500 mm.

Model specifications

1. The general size of the model and specification of the corrugated pipe is 6 meters, and there are also 9-meter customized pipes.

2. Double-wall corrugated pipe specifications: DN160mm, DN200mm, DN300mm, DN400mm, DN500mm, DN600mm,

DN800mm. Under normal circumstances, the quality of SN4 and SN8 is better than S1 and S2. Corrugated power pipes are called corrugated pipes.

3. Models and specifications of corrugated pipes. The colors of double-wall corrugated pipes are divided into black inside and black outside, blue inside and black outside, and occasionally yellow inside and black outside. They are mainly customized according to customer requirements. Some customers also divide them into S1 and S2.

Performance characteristics

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

① Strong resistance to external pressure

The outer wall has a ring-shaped corrugated structure, which greatly enhances the ring stiffness of the pipe, thereby enhancing the resistance of the pipe to soil load. In this performance, HDPE double-wall corrugated pipe has obvious advantages over other pipes.

② Low engineering cost

Under the same load conditions, HDPE double-wall corrugated pipes only need thinner pipe walls to meet the requirements. Therefore, compared with solid wall pipes of the same material specifications, it can save about half of the raw materials, so the cost of HDPE double-wall corrugated pipes is also low. This is another outstanding feature of this pipe.

③Easy to construct

Due to the light weight of HDPE double-wall corrugated pipe, it is easy to carry and connect, so the construction is fast and the maintenance work is simple. Its advantages are more obvious under tight construction period and poor construction conditions.

④Small friction coefficient and large flow rate

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

⑤Resistant to low temperature and impact resistance

The brittle temperature of HDPE double-wall corrugated pipe is -70℃. Under normal low temperature conditions (above -30℃), no special protective measures are required during construction. Construction is convenient in winter, and HDPE double-wall corrugated pipe has good impact resistance.

⑥Good chemical stability

Since HDPE molecules have no polarity, they have excellent chemical stability. Except for a few strong oxidants, most chemical media do not damage them. The soil, electricity, acid and alkali factors in the general use environment will not damage the pipeline, will not breed bacteria, will not scale, and its flow area will not decrease with the increase of running time.

⑦ Long service life

Under the condition of not being affected by sunlight ultraviolet rays, the service life of HDPE double-wall corrugated pipe can reach more than 50 years.

⑧ Excellent wear resistance

Germany has proved through experiments that the wear resistance of HDPE is even several times higher than that of steel pipes.

⑨ Appropriate deflection

A certain length of HDPE double-wall corrugated pipe can be slightly deflected in the axial direction, and is not affected by a certain degree of uneven settlement of the ground. It can be laid directly in a slightly non-straight groove without pipe fittings, etc.
