Dual Circulating Sub

The Wellpro Group Dual Circulating Sub is designed as a circulating component within the BHA.


The circulating sub is ball activated and, when utilised, introduces a flow path from the tool ID to the annulus thus allowing for higher circulation rates.  If, for any reason, circulation through the tool string is lost, a rupture disc option is also included as standard.  This can be set and ruptured at a predetermined pressure.
