Trenchless technology has not quietly emerged in China in the twentieth century. It has been applied to the trenchless construction of various pipelines. Among them, the special working environment of power pipelines has become the top priority. The long-term operation of power cable exhaust pipes is around 70ºС. And must withstand the external pressure of underground muddy water. In the early day
Comprehensive and scientific understanding of MPP power cable protection tube The MPP power pipe is divided into ordinary type and reinforced type, and the reinforced type is divided into excavation pipe and non excavation pipe. The so-called MPP non excavation pipe is also called MPP jacking pipe, MPP supporting pipe and MPP traction pipe.
Steel belt reinforced polyethylene (PE) spiral corrugated pipe for underground drainage uses polyethylene as the outer base material, the surface is coated with high-performance bonding resin, and the steel belt wave body bent and formed is the main support structure. The spiral corrugated pipe is integrated by winding and extruding. The product combines the advantages of high rigidity, high stren
Steel belt pipe is also called steel belt reinforced polyethylene (HDPE) spiral corrugated pipe (hereinafter referred to as MRP) for underground drainage. It is a new type of plastic buried drainage pipe developed in China in recent years. The product is wound with spiral steel ribs pressed into an approximately ^ shape by a continuous steel belt between the inner and outer layers of heat fusion p
Exploring the space for plastic spiral pipe technology upgrade The plastic winding pipe in the drainage pipe network has developed by leaps and bounds since it was introduced into China in the late 1990s. It has been playing a leading role in the drainage system. Currently, there are more than 3,000 production lines in operation in thousands of domestic enterprises. -The specifications within t
HDPE winding pipe clamp connection operation method A. 1. Connection of pipeline and inspection well: The connection between the pipeline and the wall of the inspection well shall meet the design requirements. If there is no specific design requirement, the following methods may be adopted: (1) When the HDPE winding pipe has been laid in place, it is advisable to use cast-in-situ concrete to
PE steel tape winding pipe we should know As the name suggests, it is to add a steel band to the plastic tube. The steel belt reinforced spiral corrugated pipe for underground drainage is made of high-density polyethylene (PE) as the matrix, and the steel belt coated with adhesive resin is formed into a corrugated shape as the main support structure, and is twined with polyethylene material to fo
What is the current situation of China's PE winding pipe market? According to what I know, PE winding pipe with polyethylene winding structure has the characteristics of light weight, low roughness of the inner wall of the pipe, and large water transfer volume with the same pipe diameter. The replacement products of cement substitutes have been widely used abroad. Over the past few years, they hav
