Product Description

Pre-insulated Pipeline Girth Welding Closure
Used on pipeline connection and repairment.


1. Rated Voltage: 220/380V
2. Tensile strenth: 280kg/cm2
3. DN250--DN1372*500/600MM

Application:
1. District heating system(pipe), district thermal heating;
2. Steel pipes of anticorrosion;
3. Preinsulated bonded pipe system for directly buried hot water networks;
4. Three PE/PP layers with foam jacket insulations pipes connections;
5. Sewer lines instruction. (metal spirally reinforced corrugated pipe);
6. Water supply network; Drainage pipes network;
7. Oil

Advantages:
1. Waterproof;
2. Able to withstand axial forces initiated by axial moments of the pipe in the ground;
3. Able to withstand radial forces and bending forces;
4. Able to withstand effects of temperature and temperature variations.
5. Have the same thickness of the pipeline insulation layer.
