During petrochemical operations, where hydrocarbons are present in liquid or gas form, inflatable stoppers are often used for various applications such as debris stopping, leak testing, low-pressure hydrostatic tests, blocking the release of hydrocarbon gases and a variety of plumbing operations.
To meet the challenges of such intense conditions, the Pipestoppers® Division of Huntingdon Fusion Techniques HFT® manufacture a range of hydrocarbon resistant versions called PetroChem® Inflatable Pipestoppers®.
Standard models 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).
The versatile Inflatable Stoppers are used to service a wide variety of industrial applications. As “overnight stoppers” they provide a strong barrier in pipeline activities, to prevent foreign bodies entering the line during downtime.
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.
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.
These 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.
PetroChem® stoppers are light in weight and easy to manipulate and can be shipped anywhere by next day courier at very low cost.
In addition, the inflatable versions weigh much less than most of their counterpart sizes of mechanical plugs, making them easier to transport and safer to use at height.
