HDPE Butt Fusion Injection Equal Tee
***Advantages and welding of PE pipe fittings:
PE pipe fittings is light, which is more common for partial application pe80 pe100 grade level and two standards , including :
PE80 density of about 0.94 g / cm 3, PE100 density of about 0.96 g / cm 3 ;
Easy thermoplastic - easy to process ( such as injection molding, extrusion molding
Remanufacturing easy recycling
Good resistance to radiation and chemical stability
Good resistance to cold , the temperature can be -40 ℃ to
Excellent electrical insulation properties , is not affected by electrolytic corrosion
Malleable - extended break PE80> 700% PE100> 600%
Anti- erosion resistance - 8 times better than steel
Approximately half of the low thermal conductivity of glass
Smooth surface , unlike the role of metal pipes rust easily with oxygen crusts
pe pipe connection into fused pipe connections and fittings connected to melt , the more ordinary side, the other , as well as socket connections, this method is applied to a small size.
1 , fused connection : Follow these steps: First check , and then is cut pipe , pipe fittings joints clean , scrape the oxide layer , connecting the two parts of the tube and pipe fittings , calibration welder , welding parameter adjustment in accordance with the welding voltage, welding Dimensions , electricity, welding, and then finally cooled.
2, the hot melt connection : the inner surface of the pipe surface and the pipe is inserted while the welding is non-rotating die head is heated for a few seconds , then quickly removed and welding device , the heat pipe has a fast vertical insertion tube , packing, cooling to .
3 , socket connections, relatively simple, not elaborate here .
