Performance of Electrofusion Joints for PE Pipes
Price: £100
Ref: 99/WM/02/10
ISBN: 1 84057 153 5
The large number of service failures of electrofusion joints remains of prime concern to UK water industry. This investigation combines the findings of two year's work looking at the effects of site conditions, joint preparation and fitting type on joint performance. A large round robin exercise was conducted with the involvement of all manufacturers to look at the effects of wet wipes on joint performance. Different wipe formulations were compared and it was found that their effects were negligible relating only to the rate of evaporation from the cleaned surface The tolerance to contamination test developed for couplings was extended for large diameter couplings and modified for tapping tees. A performance variability between manufacturers to overcome the effects of joint contamination clearly exists.
