District Chilled-Water Pipe PU Insulation in Liaoning, China

District Chilled-Water Pipe PU Insulation Project in Liaoning, China

District Chilled-Water Pipe Insulation in Liaoning, China project reference: Pipe positioning, annular sealing, PU injection, curing and handling for the specified carrier-pipe and outer-casing assembly.

Project Reference and Configuration

Project reference basis. Figures and configuration details are reported in the supplied project brief. They are reference values for the stated application, rather than verified acceptance results or a guarantee for another installation. Confirm the source records, material, tooling, operating schedule and test method when assessing a comparable project.

This project reference describes pipe positioning, annular sealing, PU injection, curing and handling for the specified carrier-pipe and outer-casing assembly.

Configuration and numerical values are reproduced from the supplied project brief for discussion. Original production, inspection and acceptance records have not been verified; these values do not establish certification or performance for another configuration.

Configuration Listed in the Project Brief

Solution Module	Typical Pipes	Core Material	Main Process	Typical Production Mode
Pipe & Pipeline	Chilled-Water Pipes (DN300–DN600)	Rigid PU Foam (68 kg/m³)	Pipe-in-Pipe Annular Injection	Heavy Conveyor Factory Line

Equipment References in the Project Brief

The supplied brief lists the following equipment references. Model identities, quantities and the actual delivery scope follow the original equipment schedule.

1. High-Output Pipe Injection Machine: Stoichiometric ratio metering, high-velocity impingement injection & shot control
2. Heavy-Duty Pipe End Clamping Flanges: Pneumatic annular sealing with microporous air-venting filter plugs

Project Reference Values

0.16 MPa

Reference: Axial-Shear

Project-brief reference; original records pending. The brief lists 0.16 MPa for the pipe assembly. Confirm the specimen, procedure and original report. No standards conformity or accredited-laboratory result is asserted without its records.

0 reported incidents

Reference: Corrosion-Observation

Project-brief reference; original records pending. The brief lists no detected corrosion incidents in a 12-month observation period. Confirm the inspected pipe network and records; this is not a universal corrosion-free result.

60 pipes/shift

Reference: Fabrication-Output

Project-brief reference; original records pending. The brief lists sixty 12 m pipes per shift. Confirm pipe diameter, shift hours, station sequence and production logs. This shift figure is not automatically daily output.
