Claims8
A head housing for curing of resin pipeline lining comprising:
- a base;
- a mounting ring raised face (2) at a first end of the base;
- a ring raised face (3) at a second end of the base;
- an inlet (4) mounted on a conical recess (8) on a front surface (9) of the ring
- raised face (3);
- an outlet (5) located at the front surface (9) of the ring raised face (3);
- at least one spiral shape cooling passage (6) extending from the inlet (4) to the outlet (5), the at least one spiral cooling passage (6) having a spiral line having a first radius (R1) by the inlet (4) and a second radius (R2) by the outlet (5), wherein R2=0.5R1;
- the at least one cooling passage (6) having a length S more than twice a length L of a longitudinal part (1) of the housing.
