Socket Fusion Process
-
Is the heating iron within current calibration (6 monthly), the teflon coating in good condition and the plates secured tightly?
-
Is all electrical equipment within current test status?
-
Is the portable generator the correct size (ie. Minimum 1.5kW output)?
-
Is a ground sheet used for storage of tools and equipment for the task?
-
Does the worker hold the appropriate competency to complete fusion tasks (ie. PMBWELD301)?
-
Has the end of the pipe been straightened for 0.5mtr and the end squared by severing with pipe cutters?
-
Has the pipe end been cleaned with 'Norton 180 grade' wet & dry sandpaper and clean water?
-
Has clean paper towel been used for drying, by wiping pipe in one direction only (to avoid cross contamination)?
-
Has a nylon stiffener been inserted into the pipe end without touching the cleaned surface? For 10mm & 16mm pipe the stiffener should protrude approx 3mm. For 18mm, 20mm and 25mm pipe the stiffener should be flush.
-
Has the depth gauge on the cold-ring pliers been used to determine correct location (ie. on the end of the stiffener)?
-
With the heating iron at the correct temperature (red indicator light is off) has clean paper towel been used to wipe the teflon plates?
-
Have the pipe ends been placed into the heating iron, at full engagement depth, for 10 seconds using a timing device?
-
Was pipe and socket joined, without delay, to full engagement depth for 1 minute using a timing device?
-
Was the time of fusion recorded on the joint (Cooling period is minimum 15 minutes)?
-
Were the faces of the heating iron cleaned with paper towel?

Saddle Fusion Process
-
Is the heating iron within current calibration (6 monthly), the teflon coating in good condition and plates secured tightly?
-
Is all electrical equipment within current test status?
-
Is the portable generator the correct size (ie. Minimum 1.5kW output)?
-
Is a ground sheet used for storage of tools and equipment for the task?
-
Does the worker hold the appropriate competency to complete fusion tasks (ie. PMBWELD301)?
-
Has the PE main been cleaned thoroughly with 'Norton 180 grade' wet & dry sandpaper and clean water?
-
Has clean paper towel been used for drying, by wiping pipe in one direction only and using clean paper towel for each stroke (to avoid cross contamination)?
-
Has the saddle press been clamped, perpendicular to the gas main, without the operator touching the cleaned surface?
-
Has the operator removed the PE service tee from plastic, inspected for correct size and condition and checked the cutter is wound fully up?
-
Has the base of the Tee been cleaned thoroughly with 'Norton 180 grade' wet & dry sandpaper and clean water?
-
Has clean paper towel been used for drying, by wiping pipe in one direction only and using clean paper towel for each stroke (to avoid cross contamination)?
-
Has the Tee been placed in the saddle press and checked for alignment on the main before hand tightening?
-
With the heating iron at the correct temperature (red indicator light is off) has clean paper towel been used to wipe the teflon plates?
-
Has the concave heating iron been placed on the main and the press lowered to bring the base of the Tee in contact with the heating iron for 3 seconds to check the pattern?
-
Once pattern is confirmed as good, was the heating iron pressed firmly in position until a uniform bead developed with the pressure reduced to half for a 40 second soak time using a timing device?
-
Was the heated surface then inspected for even melt and within 3 seconds of removal the service tee was brought into contact with the main?
-
Was steady pressure applied until a second bead formed around the base of the Tee?
-
Was the joint left undisturbed until the surfaces had sufficiently hardened?
-
Was the time of fusion recorded on the joint (Cooling period is minimum 15 minutes)?
-
Were the faces of the heating iron cleaned with paper towel?
