Read MoreStop Hydrocarbon Liquids and Gases Escaping
Standard PetroChem® Inflatable Stoppers are available in Spherical and Cylindrical formats.
Cylindrical PetroChem® Inflatable Stoppers are commonly used for stopping off pipes with hydrocarbon gases and liquids inside where the inner membrane of the stopper protects the inflatable latex bag inside that.
Spherical PetroChem® Inflatable Stoppers give less contact area than the Cylindrical version, but are very useful where access is limited. Since the position of the Stopper in the pipe is not critical, it can be put at any angle, this is particularly useful when inserting into a small opening at the top of a pipe rather than at the end of the pipe.
Heat Resistant Covers
Heat Resistant Inflatable Covers are available with a performance rating to give protection up to a temperature of 300°C (572°F).

Versatile Stoppers for Multiple Applications
Inflatable PetroChem® Pipe Stoppers are made from a high-grade latex, rubber internal inflatable bag and covered with a petrochemical resistant layer which has a tough, woven polyurethane impregnated nylon cover. The Stoppers are inflated through a valve at the end of the inflation hose using a standard foot pump or compressor.
Standard Petrochemical Resistant Stoppers are available in Spherical and Cylindrical formats.
- Spherical versions are ideal for insertion through a small hole to seal a large diameter orifice.
- Cylindrical bags resist and tendency to twist radically in use.
The recommended maximum temperature for this standard range is 80oC (176oF).
These versatile Stoppers are used to service a wide variety of industrial applications such as:
- All petrochemical operations where hydrocarbons are present in liquid and gas form.
- Debris stopping during machining operations where pipes have had hydrocarbon liquids or solids inside.
- Leak testing of pipework systems where pipes have had hydrocarbon liquids or solids inside.
- Low-pressure hydrostatic tests where pipes have had hydrocarbon liquid or solids inside.
- On-site thermoforming of bends in ducting and conduit materials.
- Fibre-optic construction projects.
- Debris and animal barriers for overnight protection of pipelines where pipes have had hydrocarbon liquids or solids inside.
- Plumbing operations.
Heat Resistant Covers
For high temperatures and immersion in chemicals, HFT® manufactures a range of PetroChem® Inflatable Stoppers.
The PetroChem® Stoppers are identical to the Standard Inflatable Stoppers, however they are manufactured with an internal flexible rubber that is resistant to petrochemical fluids and vapours.
Heat Resistant Covers are available for PetroChem® Stoppers, which have a temperature range up to 300ºC (572ºF). They are manufactured from a robust material, to ensure the PetroChem® Stopper is not damaged when exposed to high temperatures.

Read MoreAvailable in all Shapes and Sizes
The standard range of PetroChem® Stoppers is available in a variety of shapes with sizes ranging from 1 to 44” (25 to 1,118 mm). They have a 1.3 m hose length, 8 mm ID, 14 mm OD and are fitted with a standard Schrader valve.
It is generally accepted that the pressure, which an Inflatable Stopper will hold back, depends on five factors:
- The surface of the pipe into which the Inflatable Stopper is to be inserted.
- The friction resistance of the Inflatable Stopper cover material.
- The total area of contact between the Inflatable Stopper and pipe.
- Whether or not the Inflatable Stopper is supported.
- The pressure inside the Inflatable Stopper itself.
