In municipal rain and sewage pipe network and water supply projects, the cost of pipe trench grooving often accounts for a small proportion of the total project cost - the cost of earthwork excavation, transportation, backfilling, and the extension of the construction period due to wide grooves are all headaches for the engineering side. The HDPE carat pipe of AD Pipeline (the full name of HDPE winding structure wall pipe), with its unique product advantages, provides an efficient solution to solve this pain point: the width of the pipe trench is more economical, which directly helps the project to reduce costs and increase efficiency.

Traditional PVC-U pipe or reinforced concrete pipe, due to its limited ring stiffness, in order to withstand the side pressure of earthwork and ensure that the pipeline is not squeezed and deformed during the construction process, it is often necessary to reserve a wider groove width. For example, for DN300 pipes, traditional pipes may require a groove width of 1.0-1 meters, which means more earthwork excavation, which not only increases the cost of excavators and transportation vehicles, but also may extend the construction period due to site restrictions - for example, in the narrow section of the old city, the construction of wide grooves will even affect the surrounding traffic and residents' lives.

The HDPE carat pipe of AD Pipe adopts a hot winding molding process, and the pipe wall presents a unique "work" structure. This design greatly improves the ring stiffness of the pipe (conventional up to SN8-SN16), and the resistance to external pressure far exceeds that of traditional pipes of the same specification. That is to say, even if the groove width is reduced, the pipe can withstand the pressure of the surrounding soil without deformation or damage. Taking DN500 pipe as an example, the traditional PVC pipe needs about 1.1 meters of groove width, while the AD HDPE carat pipe only needs 0.7-0 meters, and the slot width is reduced by nearly 30%!

In addition to the structural strength, the connection method is also the key. The AD HDPE carat pipe adopts heat shrinkable sleeve connection or electric fusion connection, and the operation process does not require too much space - the worker only needs to reserve a small amount of space at the end of the pipe to complete the whole process of heating, socket connection and cooling. Compared with the socket connection of the traditional pipe (which requires a large space to adjust the angle), the connection method of the carat pipe further compresses the demand for groove width, making "narrow groove construction" possible.

In the old urban area of a southern city, the rain and sewage diversion renovation project used the AD HDPE carat pipe. The narrowest section of the project is only 3 meters, and the wide groove construction of traditional pipes will occupy most of the road surface and affect the travel of residents. After the use of AD carat pipes, the width of the grooves is reduced from 1.2 meters to 0.8 meters, which not only solves the problem of site restrictions, but also reduces the amount of earthwork per kilometer by about 220 cubic meters, which directly saves about 60,000 yuan. At the same time, the construction of narrow grooves shortens the construction period by 12 days, and completes the pipe network transformation in advance, which has won the praise of the local government and residents.

It is worth mentioning that the weight of AD HDPE carat pipes is only 1/8 of that of concrete pipes of the same specification, and the transportation and hoisting are more convenient. Even in a narrow groove environment, workers can easily complete the pipe laying, further improving the construction efficiency.

As a well-known brand in the plastic pipe industry, AD Pipe always focuses on the combination of product performance and engineering requirements. The advantage of HDPE carat pipe is not only the embodiment of product technology, but also a "cost reduction tool" for the sake of the engineering side. Whether it is municipal engineering, industrial park pipe network or rural sewage treatment projects, choosing AD HDPE carat pipe can effectively reduce construction costs and time costs on the premise of ensuring project quality.
