Smart Spray-In-Place Pipe (SIPP) Rehabilitation

Beijing Urban-Renewal Solutions provides end-to-end Spray-In-Place Pipe (SIPP) rehabilitation for aging underground pipeline networks. By integrating proprietary polymer lining materials, intelligent spray robotics, and a mobile command system, we deliver consistent results across complex site conditions—without disruptive excavation.

• Leakage and corrosion in pressurized pipelines
• Capacity loss, infiltration, and deterioration in gravity pipelines
• Irregular geometry (bends, reducers, offsets) and limited access constraints
• High-safety operating environments requiring controlled quality and traceability

1. Municipal water supply (pressurized)

   • Best for: Pressure-bearing mains where reliability, leak control, and structural recovery are critical.
   • Typical outcomes: Reduced leakage risk, restored internal protection, improved structural integrity, and extended service life with minimal disruption.
   • SIPP approach: Seamless in-situ sprayed lining with controlled application and quality assurance.

2. Municipal drainage networks

   • Best for: Pipelines requiring improved flow performance and structural recovery. SIPP excels at lining large diameter pipes, tunnels, and non-circular cross-sections where prefabricated liners are not capable.
   • Typical outcomes: Restored hydraulic capacity and long-term durability, with minimal surface disruption—often maintaining traffic flow with only one lane impacted.
   • SIPP approach: Tailored material selection and process parameters to match pipe condition and operating constraints.

3. District heating networks

   • Best for: Systems with temperature and reliability requirements.
   • Typical outcomes: Improved integrity and service continuity with reduced excavation and reinstatement work.
   • SIPP approach: Customized materials and process control designed for the operating environment.

4. Oil & gas / petrochemical (customized)

   • Best for: Higher safety requirements and specialized site constraints.
   • Typical outcomes: Durable rehabilitation with enhanced QA/QC and project traceability.
   • SIPP approach: System solution combining materials, equipment configuration, and standardized methodology.

5. Industrial pipelines

   • Best for: Plant networks needing fast turnaround and minimal production disruption.
   • Typical outcomes: Efficient renewal with reduced downtime and improved long-term performance.

• Bonded lining, not just contact pressure: Sprayed and cured directly onto the host pipe surface to form a continuous bonded interface — unlike many pre-fabricated liners that depend mainly on expansion pressure and end sealing.
• One integrated system: Materials + robotics + mobile command + standardized methodology, engineered to work together.
• Built for complexity: Adaptable process parameters and equipment configurations for inverted siphons, trench/river crossings, reducer (transition) sections, and single-entry (limited access) pipelines.
• Strong performance in pressurized rehabilitation: The bonded lining interface is a key enabling factor for pressure-bearing pipelines (internal and external pressure scenarios). Designed around the reliability and performance requirements of pressure-bearing pipelines.
• Quality and delivery assurance: Standardized workflows, inspection checkpoints, and engineering governance for repeatable outcomes.
