Description of PE double wall corrugated pipe in pakistan
1. The unique structural wall of PE double wall corrugated pipe in pakistan
In pakistan design has high ring stiffness, which enables the pipeline to have excellent compression resistance and the ability to adapt to complex environments.
2. The PE double wall corrugated pipe pipe wall is smooth and the flow resistance is small.
The same drainage volume can meet the discharge requirements by choosing a pipe with a smaller diameter than other pipes.
The plastic drainage pipe of the same diameter can pass 30-40% higher than the reinforced concrete pipe under the same hydraulic gradient. In addition, the PE material has good hydrophobicity, the sludge impurities in the domestic sewage are not easy to deposit and scale on the inner wall of the pipe, and the amount of pipe cleaning is small in pakistan.
3. PE double wall corrugated pipe is Lightweight, convenient, and quick to carry, connect and install.
It can be directly laid in trenches without a foundation, and is especially suitable for projects with complex geological conditions and environments or where rapid construction is required in densely populated areas; the project cycle is short and the overall cost is low.Such high quality PE double-wall corrugated pipe is very suitable for Pakistani market.
4. PE double wall corrugated pipe is resistant to corrosion by various media such as acid and alkali.
Under the correct use conditions, its service life is more than 50 years.
The buried PE double-wall corrugated pipe is not exposed to ultraviolet rays, the temperature change is small, and there is no problem with ultraviolet radiation and temperature aging.
In urban construction in Pakistan, sewage pipes are mixed with various acid and alkaline liquids. This poses a certain threat to general metal drain pipes. But PE double wall corrugated pipe has very strong corrosion resistance. Ensure the normal operation of the drainage pipes.
5. PE double wall corrugated pipe has Wide temperature range.
The PE double wall corrugated pipe will not break in an environment of -60℃, and the maximum temperature of the conveying medium is 60℃. In some parts of Pakistan, the temperature is extremely low in winter. Even in such severe winter, the pe corrugated pipe can work stably.
6. PE double wall corrugated pipe Rubber ring socket connection, flexible interface, good tightness, and strong resistance to uneven settlement.
It adopts a socket connection and is sealed with a rubber ring, the link is reliable, not easy to leak, and does not cause any pollution to the environment.This is very competitive in the Pakistani market once and for all.
7. PE double wall corrugated pipe is Low installation cost.
The installation cost of PE double-wall corrugated pipe is about 40% of that of cement pipe, which is about 20% less than the installation cost of steel pipe. The service life can reach more than 50 years. Therefore, the comprehensive total cost is lower than that of reinforced concrete pipes of the same diameter.

Corrosion and Abrasion Resistance of Double Wall Bellows
Double-wall corrugated pipe high-density polyethylene (HDPE) has excellent chemical stability, aging resistance, and resistance to environmental stress cracking properties. The HDPE double-wall corrugated pipe produced from it is flexible. Its main performance is as follows:
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, the HDPE double-wall corrugated pipe has obvious advantages compared with other pipes. Advantage
Low engineering cost: Under the condition of equal load, HDPE double-wall corrugated pipe only needs a thinner pipe wall to meet the requirements. Therefore, compared with the solid-wall pipe of the same material and specification, it can save about half of the raw materials, so the cost of the HDPE double-wall corrugated pipe is also lower. This is another very prominent feature of the pipe.
Convenient construction: Due to the light weight of the HDPE double-wall corrugated pipe, the handling and connection are very convenient, so the construction is fast
The small 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 diameter. In other words, under the same flow requirements, HDPE double-wall corrugated pipes with relatively small diameters can be used.
The advantages of HDPE double-wall corrugated pipes in engineering are already obvious. If you open a chemical plant in Pakistan, you will inevitably have to deal with some acidic or alkaline solutions. The corrosion resistance of drainage pipes is particularly important.
Low-temperature impact resistance: The embrittlement temperature of HDPE double-wall corrugated pipe is -70℃. Generally, it is not necessary to take special protective measures during construction under low-temperature conditions (above -30 ℃), and construction in winter is convenient. Moreover, the HDPE double-wall corrugated pipe has good impact resistance.
Good chemical stability: Since the HDPE molecule has no polarity, it has excellent chemical stability. Except for a few strong oxidants, most chemical media have no destructive effect on them. The soil, electricity, acid, and alkali factors of the general use environment will not damage the pipeline, breed bacteria, and scale, and its flow area will not decrease with the increase of operating 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 has used tests to prove that the wear resistance of HDPE is even several times higher than that of steel pipes.
