Difference 1: Features

The MPP conduit pipe adopts modified polypropylene (PP) material, which has good insulation performance, high temperature resistance, strong compression resistance, light weight, convenient construction, smooth inner and outer walls, low friction, long service life and good performance .

CPVC conduit pipe uses chlorinated polyvinyl chloride (pvc-c) resin as masterbatch, high strength, good flexibility, high temperature resistance, corrosion resistance, flame retardant, good insulation performance, no pollution, no aging, light weight, easy construction Features.

 

Difference 2: Applicability

Compared with the traditional trenching and burying method, MPP conduit pipes are more convenient for construction, reduce damage to the road surface, have a wide range of applications, and can also lay pipelines in areas where excavation operations cannot be carried out, such as Monuments protection areas, downtown areas, crop and farmland protection areas, highways, rivers, etc. It is suitable for high voltage transmission line and cable exhaust pipe of more than 10KV.

The main scope of application of CPVC conduit pipes: urban power grid construction and reconstruction; urban municipal reconstruction projects; civil aviation airport engineering construction; engineering parks, community engineering construction; transportation, road and bridge engineering construction, urban street lamp cable laying, and play a guiding and protective role. The product has great performance, which is better than traditional asbestos cable exhaust pipes and ordinary PVC pipes. It is an ideal substitute for traditional power pipes and cable sheath pipes.

 

Difference 3: connection method

The MPP conduit pipe is welded by hot-melt welding with a welding machine. The welding point is about 200 degrees, and it cannot exceed 220 degrees. When the temperature reaches, you can connect the two ends.

CPVC conduit pipe adopts socket connection, and a high-temperature rubber ring is added at the expansion socket connection to prevent thermal expansion and contraction. It is composed of joints, waterproof seals, brackets and other components.
