Today, we’re introducing to you... MPP power pipe This highly specialized-sounding name is unknown to many people. In fact, the MPP power conduit standard refers to a type of pipe made primarily from modified polypropylene—a material that’s widely used in everyday life. It can be put into service without requiring extensive excavation, earthmoving, or damage to road surfaces.
I. Material of MPP power conduits:
The non-excavation modified polypropylene (MPP) protective conduit for power cables is a new type of plastic pipe made from modified polypropylene as the primary raw material, using a special formulation and processing technology. It boasts a range of advantages, including high strength, excellent temperature resistance, ease of cable installation, simple construction, and cost savings. Modified polypropylene non-excavation pipes are widely used as protective conduits for power and communication cables. When employed in pipe jacking operations, these pipes particularly highlight their unique characteristics. They meet the requirements of modern urban development and are suitable for burial depths ranging from 2 to 18 meters. The application of trenchless pipe-laying technology offers numerous benefits: it does not pollute the environment, does not disrupt traffic, causes minimal damage to the geological strata, ensures safe and reliable construction, shortens construction periods, eliminates the need for transporting and stockpiling excavated earth, reduces costs, and delivers significant social and economic benefits. The scope of its applications is very broad. By employing non-excavation techniques to install modified MPP protective conduits for power cables, we not only ensure the reliability of the cable network and reduce its failure rate but also greatly improve the urban landscape and environmental quality.
II. MPP Power Conduit Standard:
MPP power conduits play a significant role in our daily lives, yet their standards are extremely stringent. These conduits feature high-temperature resistance and excellent resistance to external pressure, making them suitable for use as conduit materials for high-voltage power cables operating at 10 kV and above. The standard dimensions of MPP power conduits range from 110 mm to 250 mm and are available in two types: standard and reinforced. The standard type is appropriate for projects involving open-cut installation and trenchless crossing installations where the burial depth is less than 4 meters; the reinforced type is designed for trenchless crossing installations with burial depths exceeding 4 meters. Now, let’s take a closer look at other standards applicable to MPP power conduits.
III. Scope of Application for MPP Power Conduits:
MPP power conduit It can be widely used in pipeline projects such as municipal, telecommunications, power, gas, tap water, and heating systems. MPP power conduits are suitable for both trenchless horizontal directional drilling projects—both urban and rural—and open-cut power conduit installation projects. MPP power conduits are also ideal for trenchless horizontal directional drilling sewer and drainage pipe installations in urban and rural areas, as well as industrial wastewater discharge projects.
IV. Advantages of MPP Power Conduits:
1. MPP power conduits have excellent electrical insulation properties.
2. MPP power conduits feature a high heat distortion temperature and excellent low-temperature impact performance.
3. MPP power conduits have higher tensile and compressive strength than HDPE.
4. MPP power conduits are lightweight, smooth, have low friction, and can be joined by hot-melt welding.
5. The long-term operating temperature of MPP power conduits is -5 to 70°C.
V. Construction Notes for MPP Pipes:
During the transportation and construction of MPP power conduit pipes, it is strictly prohibited to drop, impact, scratch, or expose them to direct sunlight.
During hot-melt butt fusion of MPP power conduits, the axes of the two pipes must be aligned, and the end faces must be cut cleanly and evenly.
The processing temperature, time, and pressure for MPP power conduits should be adjusted accordingly based on the weather conditions.
The minimum bending radius of MPP power conduit pipes shall be ≥75 times the outer diameter of the pipe.
