Plugs and Stoppers for all applications

HFT®’s Plugs and Stoppers range are designed and manufactured for a variety of applications.

“One of our inspection techniques requires the tubes to be flooded with water and we use your HFT Pipestoppers^® Plugs on vertical exchanger tubes. They work really well.” Richard Granville from Oceaneering.

The Pipestoppers® Division Manufactures:

• Lightweight Nylon Plugs for cleanliness and orbital welding techniques in addition to pharmaceutical and medical applications. Other applications for these lightweight plugs include leak testing, sealing, isolation and weld purging. Manufactured in sizes 0.5 up to 6” (12 – 150 mm), the Nylon Plugs are available individually or in ready-made kits. 

• Heavy-duty Aluminium Plugs for arduous duties such as exposure to high temperatures and immersion in chemicals. They are manufactured in sizes 1.5 to 36” (38 - 900 mm).

• Steel Plugs are available up to 72" (1,800 mm) are also in double versions for enhanced sealing. These very heavy-duty plugs are suited to applications such as long immersion in water or exposure to higher temperatures, for which the other plugs within the Pipestoppers® Range may not be suitable.

• Inflatable Stoppers are manufactured in various shapes including Low Profile, Cylindrical and Spherical. There are PetroChem™ resistant versions and high-pressure Rubber Plugs as additional products. Inflatable Rubber Plugs can be used for pressure testing. They are available in 1 – 2.5 bar options, with 6 bar versions available in sizes below 24” (610 mm). The Inflatable Stoppers are designed for several applications including blocking pipes, tanks or other orifices, weld purging, routine maintenance or to prevent the entry of foreign bodies or vermin. The maximum hold back pressure for our low cost, nylon covered latex stoppers is 4 mbar and for higher pressures the Rubber Plugs are used.

Whether your application is welding where there are numerous pipe ends to be blocked for weld purging and to prevent draughts from adversely influencing the welding activities, refuse sites for monitoring gas emissions, on-site machining industry to prevent the ingress of machining fluid, machining swarf and miscellaneous metal pieces from entering pipework and systems beyond, the Pipestoppers® Division has the solution!
