Pe pipe environmental protection health water supply pipe hot melt docking method:
1. Before and after hot-melt connection, clean the welder to indicate and heat the tool. Welding indicates that the dirt is cleaned with a clean cloth and the polyethylene residue on the heating tool can only be removed with a wooden scraper.
2. Check if the butt welder matches the pipe diameter and the specified butt weld cycle.
3. The heating time and heating temperature of the hot melt connection shall comply with the regulations of the connection tool manufacturer and the pipe and pipe production plant. The welding temperature is usually between 200 °C and 235 °C.
4, hot-melt connection pressure, cooling time, should comply with the hot melt connection tool production plant and pipe, pipe production plant regulations, during the pressure and cooling time, do not move the connector or apply pressure on the connector.
5, pe pipe hot melt butt joints should meet the following requirements:
1) Clamp the socket end of the pipe and fitting on the butt welder and clean the socket end.
2) Move the movable clamp, plan the joint surface of the pipe and pipe fittings on the milling cutter, remove the milling cutter, and check the joint surface of the pipe end so that the gap is no more than 0.3mm.
3) Straighten the two corresponding parts on the butt welder so that they are on the same axis, the wrong side should not be greater than 10% of the wall thickness.
4) Place the heating tool between the two joint faces. The tube on the butt welder is brought close to the heating tool and a certain pressure is applied, and the direct motion melts to form a smoothly symmetrical cuff along the entire outer circumference of the pipe.
5) After the heating is completed, the connected parts should be quickly separated from the butt heating tool, and a uniform external force is applied to make it completely contact to form a uniform flange.
We have a wide range of standard shackles available that include: us shackle, European shackle, Japan shackle, German shackle, and else. common surface treatments are Cr+6 free zinc, zinc nickel alloy, electroless nickel plating or customer specified types, theses plating can stand 120-680 hours salt spray anti rust testing. shackle is forging processed, high tensile and big strength.
