MPP power cable protection pipes produced by Hangzhou Xinlu Industry Co., Ltd. are straight stiff solid wall pipes mainly made from modified polypropylene, together with necessary additives, formed by extrusion molding.
Urban and rural trenchless horizontal directional drilling cable piping projects, and open-excavation cable piping projects.
Urban and rural trenchless horizontal directional drilling sewage water discharge pipe projects.
Industrial wastewater discharge projects.
Commonly used pipes are divided into common type and reinforced type. The common type is suitable for projects of excavation and laying construction and trenchless crossing construction with a buried depth less than 4 meters; the reinforced type is used for projects of trenchless crossing construction with a buried depth greater than 4m.
Excellent electrical insulation
Higher heat distortion temperature and low-temperature impact properties
Better tensile strength and compression resistance than HDPE
Light, smooth, small friction resistance
No need of excavation construction, flexible joints made by hot fusion welding, high strength of welding joints, resistance to super-long distance dragging at high traction
Good toughness, excellent resistance to ground subsidence and seismic performance
Long-term use temperature: -5~70℃
