Huntingdon Fusion Techniques Inflatable Stoppers - Cylindrical & Spherical - 457mm
Huntingdon Fusion Techniques HFT Inflatable Stoppers are designed to swiftly and effortlessly halt gas or liquid flow, prevent debris accumulation, and deter the entry of undesired substances or creatures into pipes and ducts. The adaptable Pipestoppers Inflatable Stoppers are capable of being inserted and retracted through narrow openings, and once inflated, they expand to their maximum size to facilitate stopping operations.
Cylindrical Inflatable Stoppers, being longer than their diameter, maintain stability and prevent inversion within a pipe even when subjected to pressure. Spherical Stoppers are utilized in situations where the stopper's position is irrelevant, as they can create a seal regardless of the angle at which they are placed.
FAQs
1. How do I know when to choose between a Mechanical and an Inflatable Stopper?
HFT Pipestoppers Inflatable Stoppers can be inserted and retracted through holes smaller than the one to be sealed. They are much less expensive than mechanical stoppers, but are not so suitable for applications requiring the ruggedness and strength of a mechanical stopper.
2. How do I prevent the stoppers from being pushed out of the pipe during a pressure test?
It is common to brace the ends of pipes to prevent stoppers sliding out. Contact us for further information.
3. Will your stoppers be suitable for use in petrochemical pipework where there are hydrocarbon liquids and gases present?
The HFT Pipestoppers Division manufactures special Inflatable Stoppers for the petrochemical industry where long term resistance to chemicals and/or petrochemical oils and vapours is necessary.
