MPP Power Pipe | Pressure & High Temperature Resistant,High-Voltage Cables| Haierde

MPP power pipe is made of modified polypropylene (MPP), extruded at high temperature after modified mixing.

It features excellent electrical insulation and heat resistance, applied to municipal roads, trenchless pipe jacking projects and cable laying above 10kV under roads.

Advantages of Haierde MPP Power Pipe

  • Pressure & heat resistance: Resists deformation under long-term buried load. HDPE only withstands long-term temperature up to 60℃ and deforms easily under heat from dense cables; MPP has superior heat resistance to fit high-load cable laying, eliminating hidden dangers caused by insufficient heat resistance and cable overheating.
  • •nsulation & flame retardancy with reliable electrical performance: Non-conductive and rust-free, eliminating safety hazards such as electric leakage and grounding caused by rusted perforated metal pipes.
  • Smooth inner wall for easy cable pulling: Prevents scratches on cable insulation during pulling and reduces cable damage risks, solving the problem of cable scratches caused by inner wall burrs.

Why Choose Haierde MPP Power Pipe?

  • Virgin material guarantee: 100% new modified polypropylene raw material to control quality from the source.
  • Full-size custom service: Self-owned factory supplies regular and non-standard custom sizes.

Frequently Asked Questions

Q1: Advantages over CPVC and HDPE solid wall pipes?

A: Superior high-temperature and rolling resistance, anti-cracking performance, suitable for high-voltage power projects

CPVC pipes are brittle at low temperatures; HDPE solid wall pipes deform easily under heat generated by cables

Q2: Application scenarios for SN24/SN32?

A: SN24/SN32 for arterial roads, pipe jacking, deep backfill and heavy-load lanes.

Q3: Types and distinction of MPP power pipes?

A: Standard type: For conventional direct burial and trenchless construction with burial depth ＜4m.

Reinforced type: Designed for burial depth ＞4m and heavy-load roads such as airport runways and port yards.
