Polyurethane PERT insulation pipe is called flexible insulation pipe in international, Chinese standard name is II type heat-resistant polyethylene (PE-RTII) low-temperature direct buried heating pipe.
One-step pert flexible insulation pipe production line process flow:
Pipe unwinding - unwinding traction - V-shaped wheel conveying - track feeding - encapsulation and film coating - Pouring foaming - foam curing -PE layer O-shaped extrusion - Vacuum suction coating - spray cooling - winding
Features
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.
