3LPE pipe damage/pinhole repair. up to 25 mm, apply melt stick. (with epoxy primer if the bare metal is visible) upto 300 mm, apply melt stick and repair patch. (with epoxy primer if the bare metal is visible) beyond 300 mm, apply heat-shrinkable sleeve, before preparation of surface mechanically or blasting
Can we heat live gas pipeline with gas torch kit for repairing of damage 3-LPE coating? What is the recommended temperature for heating of live gas pipeline?
For operating pipes and surface prep, I suggest to check Bristle Blaster from Monti. Coating with PE cold applied tapes (ideally 3ply with primer). If the pipe is well embedded in the ground, also Petrolatum systems could be an option (with less cleaning effort).
Very invigorative videos.

No, you can't get a torch to a live pipeline. It is normally recommended to heat up to 70 to 80 degree Celsius for repair.
