Jiangsu Youying Pipe Valve Co., Ltd.

The principle of hot melt pipe fitting welding is that the two end faces of the pipe (piece) to be welded are pressed against a preheated hot plate for a certain period of time under a certain pressure. When the crimping height reaches the standard, lower the pressure and proceed to the heat absorption stage. When the heat absorption time is completed, take out the heating plate and apply pressure on the two end surfaces to be welded so that the two welding surfaces are in close contact until the cooling is completed, and finally the two end surfaces are bonded together. Classification method of pipe fittings
Pipe fittings are divided into different types according to the construction method and purpose: electrofusion pipe fittings and hot melt pipe fittings.
.Hot-melt pipe fittings are divided according to production methods: injection molded pipe fittings and welded pipe fittings (not recommended).
3. Hot melt pipe fittings include flanges, reducers, elbows, equal-diameter tees, reducing tees and end caps, etc.
.Electrofusion pipe fittings include sleeves, reducers, elbows, tees, saddle tees, and saddle end caps.
Requirements for handling and placement of hot melt pipe fittings
. Outdoor stacking should be covered and should not be exposed to direct sunlight.
.Should be stacked on a flat ground or support.
3. Non-metallic ropes or belts should be used when transporting and hoisting pipes.
.Should be handled with care, and throwing and dragging are strictly prohibited.
Standard requirements for hot-melt butt joints
The grade and grade of hot-melt butt fittings should be the same as the grade and grade of pipes.
.Color has no impact on compatibility.
3. Different grades and pipes/fittings should not be connected using heat capacity.
.High-density pipes/fittings and medium-density pipes/fittings should not be hot-melt butted.
.Heating plate surface temperature: The recommended temperature for this process is ~3℃, which can be adjusted appropriately according to the construction environment and materials during construction.
