Sentry Saf-T-Vise Injection Sample Quills

To meet DOT operator qualifications to comply with safety standards, product operators must monitor corrosion to enable real-time decision-making around their pipelines.

Sentry Saf-T-Vise quills monitor corrosion at oil & gas and chemical plants, providing an intuitive user experience and the ability to customize their configuration.
In addition, the Saf-T-Vise quills contain a patented safety feature to increase operator safety: an easy-to-use collet that locks the shaft within the process stream in both low and extremely high-pressure conditions. This feature improves operator safety by shielding them from high-energy events from different pressures during plant operation.
The quills are versatile and can operate in both directions to inject chemicals into or take a sample from within a high-pressure pipeline.
To operate the Sentry injection & sample quill as a sampler, you can install a sampling valve on the fluid inlet. This procedure enables the collection of gas or liquid samples from any desired depth without breaking into and interrupting the product stream flow.

Advantage:

  • To avoid corrosion and equipment damage and enable accurate monitoring, Saf-T-Vise comes with a materials certification and test summary to confirm the product’s materials. These documents improve material traceability to meet the requirements.
  • The Sentry Saf-T-Vise quills can mount in any orientation at various extension lengths up to 20 feet to reach locations that are difficult to access.
  • In addition, the components are tested at safety pressure 1.5x the operating pressure. This validation feature assures compliance with PHMSA regulations and NACE standards, assuring safety while avoiding substantial financial penalties.
  • Finally, Sentry’s 30 years of experience comes with the Saf-T-Vise brand. This expertise ensures the product you select will work for your needs, and our experts also advise your team on a suitable installation location.
