Armstrong Rubber and Plastic foam insulation materials used in buried pipe insulation key in strengthening the separated gas, anti-corrosion and pressure. First of all iron pipes to be done to deal with anti-corrosion treatment, Armstrong Rubber insulation foam insulation materials structures to minimize the bonding glue joints, it is recommended every two meters port pipe seams lining and valves, bend, three Qualcomm wall materials, etc. should be bonded with iron pipes, joints completely stick tight (at least 2 hours) after Armstrong Rubber foam insulation material wrapped around outsourcing waterproof layer (such as glass cloth to emulsified asphalt cold glue for adhesive), in order to prevent soil movement and pressure, the normal practice of foreign outsourcing is no longer rigid PVC shell. |
