Continuous Pert Flexible Pre-Insulation Pipe Production Line for Building Water Supply

Meticulously Designed for PERT: Every component, from the extruder to the cooling system, is custom-engineered to meet the unique demands of PERT insulation pipe production, guaranteeing superior quality.

Low Heat Loss, High Efficiency: Utilizing polyurethane rigid foam for insulation, our PERT insulated pipes exhibit exceptionally low thermal conductivity (λ = 0.013-0.03 kcal/m·h·ºC), outperforming conventional insulation materials by 4-9 times.  
 
Minimal Water Absorption: The high closed-cell rate of the polyurethane foam (approximately 92%) results in a very low water absorption rate of about 0.2 kg/m².  

Superior Anti-Corrosion Properties: The polyurethane rigid foam insulation layer forms a tight bond with the working pipe, effectively isolating it from air and water infiltration, thus preventing corrosion and ensuring long-term structural integrity.  

Extended Service Life: PERT insulated pipes offer an impressive service life of over 50 years, significantly longer (3-4 times) than pipes installed using traditional trench or overhead laying methods. This durability reduces maintenance, replacement costs, and offers substantial environmental benefits.

Small Land Occupation & Fast Construction: Eliminating the need for large trenches, this solution reduces earth excavation by over 50% and civil engineering and concrete usage by 90%, while also shortening the construction period by more than 50%.  
 
Intelligent PLC Control: Features intelligent operation via PLC control, minimizing manual intervention, reducing electricity, water, and labor costs, and enhancing operator safety with a high safety factor.

Customized Production: Tailored production options are available to meet diverse customer requirements, backed by lifelong technical support and maintenance services.
