SWIVELS
UPETROM 1 MAI S.A. manufactures a series of swivels whose static load values range between 32 t ( 35 sht ) and 680 t ( 750 sht ). The above specified swivels are highly advantageous from several points of view, such as:
- long life provided by the quality of the materials and the heat-treatment cycles;
- a main axial taper-roller bearing that overtakes heavy loads and has reduced dimensions;
- the wash pipe sealing system can be laterally taken out and provides quick replacement of the wash pipe and seals when they get warm;
- the swivels are delivered with subs for connection with the kellies.
