Welding Process

1)  It should use heat melting method to join the pipes and fittings. Direct joining is not allowed.

2)  Pipes and Fittings should be joined when the temperature reaches at 260 O C.

3)  Pushing of pipe end into the fittings and alignment of the assembly should be within the specified time period.
