Leak Tight Pipe Plugging for the Oil & Gas Industry

There is a large variety of pipe plugging and blocking requirements in the Oil and Gas Industry, including repair work, leak testing, weld purging and debris stopping. One major concern is the entry of debris into pipes during operations.

The Pipestoppers® Division of Huntingdon Fusion Techniques HFT® now design and manufacture a range of low cost, lightweight Inflatable Stoppers, available for pipes up to 120” diameter to prevent the entry of debris into pipes.

Ron Sewell, Chairman for HFT® said: “For pipe diameters of 36” and over, not all applications require expensive and very robust, heavy rubber plugs, nor is it always necessary to use mechanical plugs which are also heavy and may be difficult to manipulate.”

“Where there is little backpressure and the absence of corrosive petrochemical fluid, lightweight Inflatable Stoppers are a great solution. They are light in weight, which makes them easy to manipulate and inexpensive to ship and because of their low cost, it is easy to keep all sizes in stock and ship them the very same day.”

HFT®'s Inflatable Stoppers are available in Cylindrical and Spherical formats. For straight pipes the Cylindrical Stoppers are recommended, whereas, for bends, the Spherical versions are more appropriate.
Where there are fluids inside pipes that need to be retained by a stopper, it is usual to use plugs made of aluminum, steel or rubber. In cases where the fluid is aggressive, nitrile, silicon or Viton rubbers can replace the standard natural rubber seals. PetroChem™ Inflatable Stoppers are also available for petrochemical duties by using a protective cover over the inflatable section.

For larger diameter pipes, Aluminum Stoppers are manufactured up to 36” diameter, and Steel Plugs up to 72” diameter. After that it is necessary to consider Inflatable Stoppers that are available up to 120” diameter and greater.

Huntingdon Fusion Techniques HFT® have a worldwide Exclusive Distributor network, which can be found at www.huntingdonfusion.com.

Long Distance Weld Purge Monitoring

Often when welding lengths of tubes and pipework fabrications of 20 metres or more, measuring the purge gas might not always easy. Under these conditions, there is a risk of contamination of the gas exiting the weld zone, leaving the welders uncertain about their welds and welding procedure.  Weld ...

Pipe Freezing with Qwik-Freezer™

Repairs or modifications on pipes can pose challenges, especially where there is liquid present inside, which may result in the expense and danger of system down time and loss of revenue while the system is drained and refilled. To dramatically reduce these costs and speed up the repair or replace ...

Welding Titanium with the Low Cost ‘Nano’

Metals that are classed as ‘reactive' (titanium, zirconium and nickel alloys) are sensitive to oxygen when heated. When welding these metals, the oxygen must be purged from the welding zone, down to as low as 10 parts per million (ppm). Weld Purging in this environment will avoid discolouration of ...

Large Diameter Pipework Fabrications

Large diameter pipework can cause several challenges, especially when those pipes are manufactured from stainless, duplex and chrome steels, titanium or zirconium. When welding such reactive materials, they need to be purged of oxygen before, during and after welding. It is not cost effective to c ...

Supplementary Gas Shielding with an Argweld® Weld Trailing Shield

Eliminating oxidation and discolouration when welding stainless and duplex steels as well as titanium, zirconium and nickel alloys is crucial in many industries today, because of improving quality control procedures. Welds have to be free from metallurgical defects otherwise they can potentially be ...
