For a long time, HDPE pipes have been widely used in the construction and transformation of water supply and drainage pipes in trenchless technology because of their excellent flexibility and corrosion resistance. However, while HDPE pipes have obvious advantages, there is also a serious problem: the pipeline is easy to scratch the surface when entering the old pipe or perforation, resulting in additional stress at the damage site, and there is a dangerous situation of crack expansion during the use of the pipe. Removing debris and sediment from old pipes is often difficult to achieve good results, so it is necessary to protect HDPE pipe surfaces from damage.

The outsourced laminating equipment is a special pipe mold designed by Guangdong BAST for excavation-free HDPE pipe. In the standard HDPE pipeline, a layer of high-hardness scratch protection layer is covered to avoid the damage to the surface of the pipeline during transportation and construction, reduce the impact of mechanical damage on the life of the pipeline, and greatly reduce the cost of transportation and installation. Even under harsh construction conditions, it will not cause damage to the pressure layer, and the original ordinary HDPE pipeline production line can be upgraded.

HDPE pipe outer cladding layer generally uses a harder material (such as MPP), the thickness is generally 0.9mm to 5mm, and increases with the increase of pipe diameter (see foreign standards in the annex); The outer cladding layer can be peeled off to facilitate the welding of HDPE pipes.
