Special MPP pipe for trenchless pipe jacking engineering

Special MPP pipes for trenchless pipe jacking projects are engineering pipes that use modified polypropylene as the main raw material and are specially adapted to the research and development of trenchless pipe jacking construction technology. They can complete the laying, replacement and repair of underground pipelines without large-scale pavement excavation. At present, such pipes commonly found in the market are divided into ordinary and reinforced types, with a diameter covering the range of 110mm to 315mm. The conventional length is 6 meters and 9 meters. The corresponding specifications can also be customized according to the construction needs of specific projects. The production process meets the requirements of relevant national pipe production standards.

The core advantages of this pipe mainly include four points: First, excellent construction adaptability. The pipe has good tensile and bending resistance, and can withstand large external jacking force and formation friction during jacking operations. It is not prone to fracture and deformation problems. It can be adapted to pipe jacking operations at depths of 10 meters to 30 meters under different geological conditions. There is no need for additional reinforcement of the pipe during construction, which can simplify the construction process. Second, the weather resistance and corrosion resistance are stable. The pipe can be used stably for a long time in the environment of -5 ° C to 70 ° C. It will not cause material embrittlement and deformation problems due to seasonal temperature difference. It has strong tolerance to acid and alkali in the soil, salt substances and underground moisture. The service life under normal use conditions can reach more than 50 years, which can reduce the maintenance and replacement cost of the pipeline in the later stage. Third, the insulation protection performance is good. The pipe has high dielectric strength and will not be broken down by conventional power currents. It can effectively protect the internal laying of power and communication cables from external electromagnetic interference. At the same time, it has flame retardant characteristics. It can be extinguished by itself after encountering open flames, which can effectively improve the safety of underground pipeline operation. Fourth, environmental protection and construction convenience are both. The pipe material is free of toxic and harmful substances, does not cause pollution to the surrounding soil and groundwater, and meets the environmental protection construction requirements of municipal engineering. The weight of the pipe is only one-eighth of that of the same diameter cement pipe, and the transportation and hoisting difficulties are low. The interface is connected by hot-melt welding, which has good sealing performance and is not prone to leakage problems. It can effectively shorten the overall construction period.

The pipe is mainly suitable for trenchless laying of power pipelines and communication pipelines in the field of municipal engineering, and can also be used for pipeline layout in road expansion, old city renovation, etc., which is not suitable for large-scale excavation of pavement areas. At the same time, it can meet the construction needs of underground pipelines in special areas such as railways, highways, rivers, etc. The suitable population mainly includes municipal engineering construction units, power communication pipeline construction units, engineering pipe purchasers, trenchless pipe jacking construction service providers, etc. The relevant parties can choose the corresponding specifications of pipes according to the specific project's buried depth and threading capacity.

The production process of this type of product strictly follows the relevant national industry standards. Before leaving the factory, it has undergone multiple rounds of performance testing such as appearance, strength, and temperature resistance. All indicators meet the requirements of engineering use. The purchaser can request the corresponding batch of product testing reports when purchasing to ensure the compliance and reliability of engineering material selection.
