Steel plugs for heavy-duty pipe blocking and stopping

as single and double models, with sealing rings made from Viton, silicon, neoprene, nitrile or natural rubbers for resistance to different temperatures and chemicals. The Pipestoppers division also manufactures lightweight Nylon Plugs for cleanliness, for orbital welding techniques and pharmaceutical and medical applications. Other applications for these lightweight plugs include leak testing, sealing, isolation and weld purging. Manufactured in sizes from 12 to 150mm (0.5" to 6"), the Nylon Plugs are available individually or in ready- made kits. The heavy-duty Aluminium Plugs allow for duties such as exposure to high temperatures and immersion in chemicals. They are manufactured in sizes 38 to 900mm (1.5" to 36"). The lighter-in-weight Inflatable Stoppers are manufactured in various shapes, including low profile, cylindrical

HEAVY-DUTY pipe blocking and stopping may require long immersion in chemicals or exposure to high temperatures, which many plugs are not capable of withstanding. The Pipestoppers ® division at Huntingdon Fusion Techniques (HFT) manufactures a range of Steel Plugs for more arduous duties, also available as double versions for even tougher applications. Luke Keane from HFT commented, “The Steel Plugs can be used for low- pressure testing, and plugging pipes, pipelines and pipework fabrications and other orifices between 2" and 48" (50 to 1,200mm) diameter. This range is specifically designed for heavier-duty applications such as long immersion in water, for use at higher temperatures or for contact with acidic or alkaline environments for which the Nylon, Aluminium and Inflatable Plugs in the Pipestoppers range are not suitable.” The HFT Steel Plugs are available

Steel Plugs – double set

and spherical. PetroChem™-resistant versions and high-pressure Rubber Plugs are available as additional products. They are designed for applications that include blocking pipes, tanks or other orifices, weld purging, routine maintenance or to prevent the entry of foreign bodies. For making ice plugs anywhere in piping systems that contain fluid, the Accu-Freeze™ and Qwik-Freezer™ systems allow repairs to sprinkler heads, and exchange of or maintenance to valves or other controls/instrumentation, without draining the system.
