Chemical Resistant Inflatable Stoppers PetroChem®

The Pipestoppers® Division of Huntingdon Fusion Techniques HFT® offers its PetroChem® chemical resistant inflatable stoppers, designed for applications such as debris stopping, leak testing, low-pressure hydrostatic tests, and blocking the release of hydrocarbon gases.

Standard chemical resistant inflatable stoppers are manufactured in cylindrical and spherical formats from 1 – 96” (25 – 2,440 mm) in diameter with a high-grade latex, rubber internal inflatable bag covered with a petrochemical resistant layer, which has a tough, woven impregnated nylon outer cover for use up to 90ºC (194ºF).

PetroChem® Stoppers are available with optional heat resistant covers to protect them against high temperatures of up to 300ºC (572ºF), ensuring the Stopper is not damaged when exposed to high temperatures.

These inflatable stoppers are particularly useful when one or more can be inserted into a small opening close to a work location, rather than at the end of the pipe, tank or vessel. No high-pressure equipment is needed for inflation.

In machining applications, they can be inserted below a horizontal flange on a vertical pipe, to prevent machining fluid, swarf and tools from falling into expensive machinery such as pumps and heat exchangers etc.
