UHX Packoff
The DTI Ultra-High Expansion Packoff provides a reliable flow through isolation solution. The expanding metal element provides high pressure seal integrity at ultra-high expansion ratios.
Deployed on Coiled Tubing, multiple Ultra-High Expansion Packoffs can be deployed in a single trip to achieve thru tubing straddle isolations.
- Ultra-High Expansion ratios
- Expandable metal mandrel/element with NBR, HNBR or Viton element
- Industry leading pressure rating, expansion ratio and ID combinations
- Highly resilient to pressure cycling
DTI offer alternate sizes, materials and thread connections. Please contact us for more information.
