Butt fusion welding method is a thermo fusion process which involves the simultaneous heating of the ends of two components
which are to be joined until a melt state is attained on each contact surface, thereby
producing a permanent, economical and flow-efficient connection.
The two surfaces are then brought together under controlled pressure for a specific cooling time and homogeneous fusion is
formed upon cooling. The resultant joint is resistant to end thrust and has comparable
performance under pressure to the pipe.
This method of jointing requires an electrically heated plate to raise the temperature of the pipe ends to the required fusion
temperature and is used for PE63, PE80 and PE100 grades of material for pipe of size
32mm and above of the same Standard Dimension Ratio (SDR). When joining pipes using butt
Pipe ranges from 32mm up to 900mm
Electro fusion welding systems are considered the most highly developed cost-effective and safe method for joining polyethylene
This jointing process uses heat generated from electricity to melt both the pipe wall and the pipe surface, creating a completely
homogenous joint that is stronger than the pipe itself. Thanks to its versatility, electro
fusion can be used to weld together pipes or fittings from different PE materials and
different thicknesses as long as there is compatibility of melt flow index and raw material
Another key advantage of electro fusion is that it is particularly suited to installations where access is difficult, such
as in trenches or around other pipes.
Pipe ranges from 20mm up to 500mm
Flanged joints are normally used to connect PE pressure pipelines to valves, pumping stations and pipelines of other pipe
materials. The joint must be able to transfer long-term axial forces with maintained
tightness, which requires use of suitable components and a correct assembly.
Compression couplings are another form of non-permanent jointing for HDPE pipes. As indicated below, the general components
of a compression fitting or coupling are a body, a threaded compression nut, an elastomer
seal ring or O-ring, a stiffener and a grip ring.
Compression fittings are popular because they do not require soldering, so they are comparatively quick and easy to use and
require no special tools or skills to operate. Because compression fittings are not permanent,
they are especially useful in installations that may require occasional disassembly or
partial removal for maintenance.
