HDPE pipe connection and installation: 1. Socket adhesive method: use hot melt adhesive, suitable for low pressure water supply and drainage, sewage, the advantage is the lowest in formation. The installation speed is the most block, especially when installing large diameter pipes, do not need those bulky hot melt machines, etc. The installation tool is most suitable for use in mountainous areas. The disadvantage is poor sealing. 2. Fast plastic joint connection method: It is a patented product, with a full range of joints, fast and reliable connection, suitable for the connection of pipes with a diameter of 110mm or less. 3. Socket hot melt method: the use of socket hot melt welding machine, excellent sealing is good, the joint is firm, low enthalpy, suitable for pipes with diameter below 200mm. 4. Butt hot melt method: With butt hot melt welding machine, the joint is beautiful and reliable, suitable for medium and large diameter pipe installation, but the equipment is heavy and costly. 5. Electrofusion coupling method: using electric fusion welding machine and electrofusion pipe fittings, the airtightness is the best, the cost is the highest, and it is used for gas pipeline installation.
