MPP cable protection tube is widely used in municipal, telecommunication, electric power, gas, tap water and other aspects in our lives. MPP cable protection tube has the characteristics of high temperature resistance and high pressure resistance, which has been loved by the majority of consumers and achieved good Social benefits, water is the source of life. As early as a few years ago, China
With the rapid development of economic development, urban construction is increasingly updated, and power cables have entered into the ground from overhead. In order to meet the needs of the market, a new type of buried MPP power cable protection tube made of MPP power cable protection tube resin as a masterbatch, with impact agents, stabilizers and other auxiliary materials extruded at high speed
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
