1. When heating: Do not insert the end of the tube into the sleeve of the heating die, but insert it to the marked depth, at the same time, push the tube into the heating die without turning to the specified mark.
2. When the heating time is reached, immediately take out the PPR pipe fittings from the heating mold, and quickly and without rotation, insert it straight and evenly to the depth of the hot melt adhesive, so as to form a uniform flange on the glass plate. Bonding and insertion should be subject to controlled rebound.
3. Attach a pipe of the same type of plastic lining material to the double fuse curved pipe fitting. When welding, the equipped hot-melt or electro-fusion welding equipment should be used. Pipes buried directly in walls or floors are to be joined by hot glue. When using a threaded or flanged connection, the interface of the threaded or flanged connection should be exposed.
4. When the aluminum alloy composite plastic pipe or flange is connected with metal pipe fittings, please use hot melt plastic pipe fittings with metal inserts as a transition. Plastic fittings and pipes lined with aluminium alloys are hot melt joined and connected to metal fittings or sanitary fittings. Accessories are connected via threaded buttons.
