Weld Purging at a Low Cost


There are many occasions where Tandem Inflatable Tube and Pipe Purging Systems are not suitable and welders are often left to construct their own Weld Purging Equipment.

Often, homemade purging devices are unsuitable and can often lead to loss of welds due to oxidation.

Weld Purging Experts Huntingdon Fusion Techniques HFT® manufacture a range of low cost, lightweight Weld Purge Plugs for a variety of applications for pipe sizes 0.5 to 6” (12 to 152 mm) diameter. 

Luke Keane, Technical Sales Manager for HFT® said: “Typical purging applications for our Weld Purge Plugs include small or odd diameter pipes, short, complicated or variable size assembles where a purging system or inflatable dam would be too long or other purging equipment may not be available or practical.” 

“We manufacture the Plugs in in a number of ready-made kits containing plugs ideally suited for the most popular size of pipes, all of which are available for immediate delivery.”

A Customer recently said: “I have used HFT®'s Weld Purge Plugs and they are very nice. I have operated a lot of Automated Welding Machines with a lot of purging involved. Hands down HFT®'s product is the best I've seen.”

Manufactured from engineering quality nylon with rubber seals made of natural black rubber, special Plugs can be made to order with sealing rings made of silicone, viton or nitrile rubbers, making them suitable for use with petrochemical fluids, high temperatures or any other conditions that might arise during use. 

The plugs are supplied with a hollow shaft with an outside ½” BSP thread for screwing on a standard hose connection or solid shaft versions up to 1.5” diameter for pressure testing.  

HFT's Nylon Plugs can be used for many other applications, including garden ponds, pool and spas and on yachts. Other applications include the stopping of pipes to prevent foreign bodies or liquids from entering or gases and liquids from escaping, blocking pipes in order to carry out routine maintenance, repair work and leak testing. As “overnight stoppers” they provide a strong barrier in pipeline activities, to prevent foreign bodies entering the line during downtime.

Save Time and Money with a High Quality Inflatable Purging System

When welding tubes and pipes made of alloys such as stainless, duplex and chrome, it is important to eliminate the oxygen internally with an inert gas. This will help prevent oxidation, discolouration and will ensure a good internal weld profile. Weld Purging long pipelines can be costly and time ...

Eliminate the Thoria and Maintain the High Performance with Blue-Tipped MultiStrike® Tungsten Electrodes

Thoria, found in thoriated Tungsten Electrodes is a radio-toxic compound and emits mainly alpha particles, which are harmful if released inside the digestive tract or inside the lungs where they act as a carcinogen. Thoriated Tungsten Electrodes therefore pose a risk to welders during grinding.  W ...

Welding Enclosures for Titanium Parts

Welding titanium alloys often has to be carried out in an environment where oxygen can be eliminated throughout the welding cycle. If the parts were to come into contact with oxygen ay any point, the reactive metal can become contaminated, oxidising which can lead to reductions in corrosion resistan ...
