Innovex’s latch-in plugs provide cost effective solutions for fluid separation and the removal of excess mud and cement film from the casing wall, while cementing production tubing or completion strings. The ratchet latch system allows multiple bottom plugs to be run and latched into each other and into compatible Innovex float equipment. Latch-in plugs can withstand high plug bump and backpressures. Precision high pressure rupture discs allow the plugs to run through restrictions without premature rupture. HNBR wiper fins provide superior wear resistance and high temperature performance, eliminating the need for clean out or scraper runs.
