Sample Collection

Often it is necessary to collect samples within a pipeline or other pressurized system to examine and measure corrosion products and other contaminants. Sentry Saf-T-Vise products offer an easy-to-use drip pot assembly series to use in collecting samples for analysis. The drip pot assemblies include a container with an interior reservoir for receiving a liquid sample, and a valve assembly coupled to the drip pot.

Drip pots are constructed from corrosion resistant 316L stainless steel and incorporate a bleeder valve on the main chamber to relieve process pressure so the sample then can be drawn safely from the sample valve. An optional corrosion coupon can be attached to the bottom of the assembly with a fixed coupon holder for simultaneous corrosion analysis and sample collection.

DPA-60  |  DPA-150  |  DPA-300  |  DPA-500
