Technical introduction of hot rolling plastic steel pipe

Hot roll-plastic steel pipe is steel roll-plastic composite pipe, it takes ordinary carbon steel pipe as the matrix, lined with PP, PE, PVC, PO, F4, F40 and other thermoplastics with excellent chemical stability. Hot rolling plastic steel pipe using plastic special equipment (sintering furnace, rolling plastic machine, etc.), the steel pipe and plastic, form a new type of anticorrosion pipe, it has the mechanical strength of steel pipe, and plastic pipe corrosion resistance, not scaling, not easy to grow microorganisms, and can guarantee the purity of delivery medium, is conveying acid, alkali, salt, gas, pulp and other ideal anticorrosion pipeline.
Production procedure of hot rolling plastic steel pipe:
(1) Production process of steel pipe (steel parts)
1. Cut the embryo pipe according to the required size 2. Welding flange (first the riveting welding, then welding on the internal and external ends) 3
(2) The lining production process
1. Heating steel pipe (steel parts): heating in the sintering furnace to reach the temperature required for the lining. 2. Fill the plastic powder into the pipe in proportion. 3
(3) Inspection
1. Lining appearance inspection: the lining surface must be smooth and smooth, no leakage point 2. Electric spark detection: 2500v-3000v / mm 3. Hydraulic test 4. Other physical experiments
