Circulating Sub

Wildcat Circulating Subs have been designed to achieve increased mud circulation by placement in the B.H.A., either above the bit or downhole motor to pump materials in case of lost circulation.

Our Circulating Subs are manufactured from AISI 4145 H material fully heat treated to give 285-341 BHN and are available in the same nominal diameters as standard drill collars or to customers' own specifications.
