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 and provide an intuitive user experience and the ability to customize their configuration.

The quills are versatile and can operate in both directions to inject chemicals or take a samples from pipelines.

Additionally, the Saf-T-Vise quills contain a patented feature to increase operator safety: an easy-to-use collet that locks within the process stream in both low and extremely high-pressure conditions. This feature shields individuals from high-energy events created from differentiating pressures. 

  • To avoid corrosion and equipment damage and enable accurate monitoring, Saf-T-Vise comes with a materials certification and test summary.
  • 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.
  • Components are tested at safety pressure 1.5x the operating pressure. This validation feature assures compliance with PHMSA regulations and NACE standards.
