What is CIPP

The In-Situ Curing Method — Explained

CIPP (Cured-In-Place Pipe), also known as the in-situ curing method, repairs damaged pipelines without excavation. A resin-soaked liner is inserted into the host pipe under air or water pressure, then cured with heat, steam or UV light to form a new structural pipe wall inside the original.

The principle is straightforward: resin heated by water/steam, or photo-cured by ultraviolet light, hardens inside the host pipe to form a new "tube-in-tube" structure with up to 50 years of service life. The new inner pipe can be put into use within hours of curing completion.

CIPP technology originated in Europe and America in the 1970s and has become the preferred method for urban water-supply and drainage rehabilitation in China and worldwide. Its three defining advantages:

  • 100% trenchless — no road or pavement damage during repair
  • Short construction window — minimal road occupation, low traffic disruption
  • 50-year service life — superior corrosion resistance and structural quality

Best for: Drainage, water, gas; pressure pipelines
Learn the process
螺旋缠绕修复

Spiral Wound Lining

PVC-U profile strips spirally wound and interlocked underground to form a continuous new pipe — works under live-flow conditions.

Range: DN600 – DN2500 mm
Best for: Large-diameter pipes & box culverts
Learn the process
聚氨酯复合基喷涂

Composite Spraying

High-strength mortar followed by polyurethane sprayed onto pipe walls — combines structural strength with corrosion protection for 50-year service.

Common Questions About CIPP

CIPP (Cured-In-Place Pipe) is an in-situ trenchless rehabilitation method. A resin-impregnated liner is inserted into the host pipe and cured with UV light, steam or hot water — forming a new "tube-in-tube" pipe wall without excavation.

Our liners cover DN100 to DN2500. UV-CIPP felt liners handle DN200–DN2200, inversion dry felt tubes work for DN100–DN2000, FIPP thermoplastic for DN150–DN1000, and spiral-wound PVC for DN600–DN2500.

A properly installed CIPP liner has a design service life of 50 years. The composite formed by resin and reinforcement fiber is highly resistant to corrosion, abrasion, and chemical attack.
