Introduction to electric heating jacket:
The electric heating sleeve is a connecting pipe member in which the PE sheet is connected to the jacket tube by electric heating through the net, bending and rolling. The Chinese name electric hot-melt sleeve material special electric heating screen melting effect is quite ideal. The first generation of electric hot-melt sleeves in China is replaced by a special electric heating screen. The joint parts are quite ideal, and the joint strength and sealing effect are very good. The first generation of electric hot melt sleeves is updated. The electric heating sleeve (belt) is welded by a polyethylene electrofusion strip with a wire embedded in the inner wall, closely attached to the outer surface of the two connected ends (over two centimeters or more), and then fastened with a heat-resistant belt; The inner wall of the pipe end of the joint is supported by a detachable tool, and then the electric resistance welding wire is used to supply the electric resistance wire. The electric resistance wire melts and expands to form a pressure, and the polyethylene on both sides of the interface diffuses with each other, and the power is turned off, and is formed after being sufficiently cooled and solidified. Reliable connection.
Applicable pipeline
Mainly used for heat pipes and oil pipes.
Good sealing performance, corrosion resistance, long life, firm, easy to operate, easy to use, low cost.
Electric heating sleeve is a new type of connecting pipe in the anti-corrosion and heat preservation industry in recent years. Its anti-aging property, joint strength and ring stiffness are obviously better than heat shrinkage tape, and the electric heating sleeve can weld the jacket tube first and then polyamine. Fat foaming, its construction speed is also significantly faster than the heat shrinkable belt, so the electric heating jacket is widely used in the joint connection of heat pipes and oil pipelines.
The electric heating jacket is developed according to many shortcomings in the joints of the directly buried pipeline joints of the previous engineering examples. It is a hot-pressed pre-embedded alloy electric heating wire process, which is produced by an automated production line with stable product quality and strong adhesion. The product energizes the electric heating jacket through a matching dedicated electric hot melt machine, which can automatically complete the welding. The operation is simple and reliable, and the construction work surface can be large or small, convenient and fast, and is a replacement product of the direct buried insulation pipe repairing sheet.
Hot melt sleeve installation:
1. When installing the hot-melt sleeve, the soil and dirt of the joint should be removed, and the hot-melt sleeve should be placed in the middle of the interface, and the heating wire should be placed on the jacket;
2. Lay the hot-melt sleeve and place the pressure plate at the hot-melt longitudinal joint to ensure that the interface is in close contact with each other. The heat-conducting parts of the hot-melt sleeve are tightly tied and fastened with the packing belt. ;
3. Connect the heating wire on the hot-melt sleeve to the control box (output), activate the switch, and set the voltage and power-on time according to the specification reference table;
4. When the edge of the joint has molten polyethylene, it will overflow, cut off the power or automatically cut off the power;
5, generally according to the site environment, the hot-melt socket requires 20-30 minutes of natural cooling, and then to remove the strap and plate.
