Beta PE-100 Pressure Pipes & Fittings

The four types of jointing commonly used for jointing BETA PE-100 pipes & fittings are,
▪ Electrofusion
In situations where butt fusion is impractical, such as when valves, elbows, and tees need to be
added, electrofusion provides a straightforward technique for joining PE pipes. Utilizing
prefabricated fittings with an electrical heating coil, the plastic of the pipe and the fitting are
melted and fused together.

▪ Butt fusion
Butt Fusion is a thermofusion process most common jointing process involves the
simultaneous heating of ends of two pipe/fitting components which are to be joined, until a
molten state is attained on each contact surface.

The two surfaces are then brought together under controlled pressure for a specific cooling
time and a homogeneous fusion joint is formed. The resultant joint is fully resistant to end
loads and has comparable performance under pressure to the pipe itself.

▪ Compression Coupling
Compression fittings are normally available only relatively in small diameters. Mechanical
assembly requires the use of fittings, generally working on the compression principle. It is
most commonly used with PE for joining the PE to a pipe or fitting of a different material, or in circumstances where fusion is not feasible and this joining method is not recommended for
pipes with diameters are exceeding 110mm.

▪ Flange Joint

Connection Flange connection is used for connecting HDPE pipes to cast iron or galvanized steel or valves and appurtenances. This connection is composed of an HDPE conversion, one end of
which is flanged and the other end is simple and of a perforated metal ring used in where pipe line need to be dismantled at a later stage or connecting PE pipes to different materials.
