Repair

1. If a pin hole is accidentally made in the (with a drill bit , for example) and the pin hole is in only one side of the pipe, it can be repaired with a new pipe by thermal welding.
2. A pin hole in pipe can be repaired with hole repair bar and repair tool in thermal welding.
3. A pin hole both side of pipe can be repaired with electrical welding couple.
   > Prepare the pipes to be welded so that they are cut perpendicular to their length, using the special pipe cutter.
   > Taking off damaged parts
   > Clean the joint area with sand cloth and cleaning solution.
   > Connect the wire terminals to the terminals on the coupling, ensuring that the weight of the wires does not rest on the joint.
   > Start welding, following the instructions on the welder.
   > Prepare new pipe same specification and length as damaged pipe.
   > Put new pipe in two electrical weilding couple respectively half respectively.
   > Start welding, following the instructions of the welding.
