performed by heating a certain point of the pipe up where it then can be bent without much effort.

Answer 19

Hot bending

Question 20

Safety measures

Answer 20

Check the equipment.

Make sure that the roller shafts are properly pinned, prior to using the pipe.

Always remember to keep your hands away from the die and rollers while you are bending the pipe.

Always use the right hydraulic oil during the maintenance, for hydraulic type.

Ensure that the pump and valve handle are in the correct position.
