Sentry ST Series
Sentry® Pipeline Integrity Products insertion & retraction tools are used to place and
retrieve corrosion coupons holders, injection & sample quills, or chemical injection
nozzles & atomizers into high-pressure applications without interruption of the
system. With their sturdy but light construction – competitor tools can weigh five
times more – these tools are operated easily by only one person and is designed to
make insertion and retraction under pressure safe, easy and quick.
Series model numbers are based on travel lengths in inches:
ST-24 | ST-30 | ST-36
The Sentry ST Series tool is used to place Sentry MM-30 and MM-50 corrosion
coupon holders into a pressurized system without interruption of the system. The ST
tool is used only during insertion or retraction and is removed once that operation
has been completed. This allows just one insertion & retraction tool to be used to
service multiple installations, saving money. The operator is able to work from a stable
and secure position to the side of the tool, with easy-to-use hand wheel operation
that can be operated in any position.
