The Non-excavation Technology of HDPE Pipeline

In municipal underground facilities, the long-term buried pipeline system is inaccessible and invisible. Whenever problems such as deformation and leakage occur, it is inevitable that it needs to be “opened” to be excavated and repaired, which brings great inconvenience to citizens’ lives. As a result, pipeline trenchless technology came into being.

1
The non-excavation technology of the pipeline is called the “minimally invasive technique” of the city. It is a safe and effective construction method for environmental protection. It can quickly and effectively repair multiple parts of the pipeline at one time without multiple excavations. , Repair, landfill.

2
Trenchless pipeline technology has developed a trenchless HDPE solid wall drainage pipe, which is suitable for areas where excavation operations cannot be carried out and meets the needs of modern life pipeline network upgrades.

3
It uses high-density polyethylene as raw material and is formed by extrusion and vacuum sizing. The inner and outer walls are smooth and flat. It is not only environmentally friendly, but also excellent in stress cracking resistance, chemical resistance, low-temperature impact resistance, etc. It has the characteristics of aging resistance and has a lifespan of up to 50 years, which greatly reduces the number of pipeline repairs and replacements, and effectively controls engineering Operation and maintenance costs.

5
One of the advantages of trenchless HDPE solid wall drainage pipes is the wide range of specifications. The range is from dn160-dn800, and the ring stiffness is SN8, SN16, and SN32, which can meet different engineering needs to the greatest extent. At the same time, its safe and reliable connectivity makes the construction process easier and more convenient.

7
On the premise of not destroying the urban landscape, not affecting transportation, not interfering with the normal life of residents, and not disturbing the underground pipelines, etc., the work order of the society is guaranteed. Improve the effect of urban infrastructure construction and make the city more unblocked.
