Blocking pipes or other orifices to carry out routine maintenance and other applications can prove challenging where hydrocarbons are present in liquid and gas form.

Now, a range of hydrocarbon resistant Inflatable Pipestoppers is available for the Petrochemical and Oil and Gas Industries. Manufactured in cylindrical and spherical formats from 1 – 96” (25 – 2,440 mm) in diameter with a high-grade latex, rubber internal inflatable bag covered with a petrochemical resistant layer, which has a tough, woven impregnated nylon outer cover for use up to 90ºC (194ºF).

The versatile Inflatable Stoppers are used to service a wide variety of industrial applications. As “overnight stoppers” they provide a strong barrier in pipeline activities, to prevent foreign bodies entering the line during downtime.

In machining applications, they can be inserted below a horizontal flange on a vertical pipe, to prevent machining fluid, swarf and tools from falling into expensive machinery such as pumps and turbines etc.

Inflatable Stoppers are particularly useful when one or more can be inserted into a small opening close to a work location, rather than at the end of the pipe, tank or vessel. No high-pressure equipment is needed for inflation.

Manufactured by Huntingdon Fusion Techniques HFT® these PetroChem® Stoppers are available with optional heat resistant covers to protect them against high temperatures of up to 300ºC (572ºF), ensuring the Stopper is not damaged when exposed to high temperatures.

PetroChem® stoppers are light in weight and easy to manipulate and can be shipped anywhere by next day courier at very low cost.

Weld Purging Post Weld Heat Treated (PWHT) Pipework

Welding processes can weaken metals by imparting residual stresses into a material, leading to a reduction in corrosion resistance properties. Post Weld Heat Treatment (PWHT) is regularly used to retain the strength of a metal when welding certain materials including high strength stainless steel a ...

Weld Purging: Replace Paper, Foam and other unsuitable Materials with Argweld® Weld Purge Dams

Weld Purging is essential when welding tubes and pipes made of reactive metals such as stainless steels, titanium and zirconium. Usually weld zones are confined with purge dams so that the use of argon purge gas is limited and waiting times are reduced. Homemade dams fabricated from paper, sponge ...

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 ...
