Self Centering Isolation and Test (SCIT) Tool

Provides a safe and efficient method for inline piping isolations and localized pressure testing of new welds.
Improve Operator Efficiency
  • Provides a safe and efficient method for inline piping isolations and localized pressure testing of new welds
  • Makes traditional system hydrotesting methods for piping modifications obsolete
Greater Usability & Coverage
  • The lightest weight tools with higher test pressure capacity than ANY OTHER mechanically actuated tools
  • Low profile, durable, aluminum construction
  • Allows ONE operator to lift isolate and test behind elbows and tees with standard tools
Lower Total Cost of Ownership
  • Dual-purpose isolation + hydrotest tools
  • Outperform other inline tools with more pipe schedules covered per tool
  • Inexpensive seals and seal backing rings

Patented Technology

Vital uses patented double block and bleed technology to achieve isolation and a positive barrier that is not only safe but verified by monitoring the pressure on the seal and behind the tool.

  • Vital’s proprietary technology provides a stronger and more reliable seal
  • Hydrodynamic capabilities keeps process piping cool for post weld heat treat
  • Safely weld on hydrocarbon lines with the peace of mind of a positive isolation
  • Test just the weld with relative ease up to 5000 PSIG

Patent # US 11,460,141 B2


Vital’s self-centring mechanism creates an operator-friendly experience and a consistent leak-free seal.

  • Minimal training as no specific bolt pattern is required
  • Cost-effective replaceable seals are schedule-specific
Fewer Tools to Manage

Compared to its competitors, Vital tools allow you to use fewer tools as all tools are Combination Isolation and Test Tools that accommodate multi-schedules via swapping out seals. The slim and lightweight design means no crane is required typically.
Double Block and Bleed Technology

Double block and bleed technology assures vapour-free isolation for hot work. Vapour is vented to a safe area, eliminating back pressure build-up. Achieve a positive hydrostatic barrier verified by pressure monitoring.
Save Water

You’ll also see significant water savings. Less than one litre of medium is required for a 24” test. The interchangeable seals can accommodate multiple schedules.
Elbow and Tee Applications
  • Slim design capable of elbow and tee applications (6” and above)
  • Able to test mismatched schedules

Water & Liquid Usage
Less than 1 gallon

  • Greater Usability & Application Coverage
  • Less tools required covering the full range of schedules
  • Reach Max test pressure on every schedule (up to 5,000 psi)

Seal Backers

tool seals of various sizes

Seal Backers “Backing Rings” can be added to achieve highest test pressure possible.

Cost Analysis Breakdown

The cost analysis breakdown is based on:

  • a typical 16" diameter pipe tie-in on a pipe rack, with an elevation 30 ft from grade
  • a typical 100 ft pipe run to the nearest valve, approximately 1,000 gallons of water
