PIPE PREPARATION

Pipe preparation is the basis of the Electrofusion process. The pipe preparation includes few simple yet important steps described below:

Pipe Cutting

Various approved pipe cutting tools

1. Rotational pipe cutter (PF-type) 2. Secateur Pipe Cutter 3. Rotational pipe cutter (S-type)

Marking and Peeling

In order to achieve a successful weld the oxide layer of the pipe must first be removed. Mechanical peeling tools are strongly preferred, as they achieve a consistent pipe surface preparation.

Rotational Peeler

Peeling is carried out to remove the oxidised material to the thickness specified by PIPA in POP001, Table 2, from the pipe surface. If the pipe diameter is still too large after peeling, additional peeling may be performed to facilitate insertion of the pipe inside the coupler, as long as the outside pipe diameter is kept to the same as, or above that specified in POP001 Table 3.
