MPP high and low voltage power pipe

MPP high and low voltage power pipe

MPP power pipe uses modified polypropylene as the main raw material, which is a construction project of laying pipes and cables in special sections such as roads, railways, buildings, and under the riverbed without massive dredging, digging and damage to the pavement. Compared with the traditional "trenching and pipe burying method", the trenchless power pipe project is more suitable for the current environmental protection requirements, and the dust flying, traffic congestion and other disturbing factors caused by the traditional construction can be removed. This technology can also be used to lay pipelines in some areas where the excavation operation cannot be carried out, such as historic sites protection areas, downtown areas, crop and farmland protection areas, highways, rivers, etc.

Introduction of double flat wall steel-plastic composite drainage pipe

Introduction of double flat wall steel-plastic composite drainage pipe

The double-flat wall steel-plastic composite winding drainage pipe developed and produced recently by Jingzhou Liangcheng Science and Technology Co., Ltd. is prefabricated into "T" type plate belt with high density polyethylene (HDPE) as the main raw material. The plate belt is wound on the pipe forming machine and welded into a pipe. At the same time, the W-type steel belt bound by galvanized steel belt is embedded in the groove between the two plates, and PE is coated on the steel belt to become the third generation of new steel-plastic drainage pipe on the outer wall of the pipe.

PE gas pipe

PE gas pipe

PE gas pipe adopts gas polyethylene pipe, which has many excellent performances and is applied in the field of gas transmission. The corrosion and joint leakage of steel pipes and cast iron pipes will be thoroughly solved, thus ensuring the safe operation of the gas pipeline network system. The PE gas pipe is made of inert material, which can resist the erosion of various chemical media. The pipe wall friction coefficient is low, the flow resistance is small, and the transmission capacity is strong. The electric melting connection is adopted. The interface strength is higher than the pipe body, and the fracture elongation of high toughness PE is generally more than 500%. PE gas pipe has good seismic performance, slow crack growth (SCG) resistance, rapid crack growth (RCP) resistance, flexibility and scratch resistance.
