BEIJING URBAN-RENEWAL SOLUTIONS CO., LTD
Company introduction
Beijing Urban-Renewal Solutions is an innovation enterprise
integrating materials R&D/production and construction services
in the field of trenchless rehabilitation. We are committed to
helping cities become safer, lower-carbon, and healthier.
Why SIPP is different
True bonded lining interface
- Sprayed and cured directly onto the prepared pipe wall to form
continuous adhesion with the substrate — unlike many pre-fabricated
liners that are primarily expanded/pressed against the host pipe.
- Improves interface integrity and load transfer, and helps reduce
the risk of under-film pathways for leakage/corrosion.
Seamless in-situ application
- Sprayed in place to conform to bends, variable diameters, offsets,
and irregular geometry.
- Eliminates seams and joints typical of prefabricated liner methods.
Superior flexibility under complex conditions
- Adaptable process parameters and equipment configurations for
challenging sites, including inverted siphons, trench/river
crossings, reducer (transition) sections, and single-entry (limited
access) pipelines.
- Proven performance in extreme conditions: sub-zero temperatures
(-21°C), high-temperature industrial applications (95°C+), and
continuous-flow scenarios.
Distinct advantages for pressurized pipelines
- Bonded-to-substrate lining is a key requirement for
pressure-bearing systems — helping resist debonding, leakage
pathways, and interface movement under internal pressure and
external loads/groundwater pressure.
- Designed around the reliability and performance requirements of
pressure-bearing systems.
Minimal disruption delivery
- Trenchless, precision application that minimizes disruption to
traffic and surrounding environments.
- Faster turnaround with reduced excavation, restoration, and overall
project footprint.
