Quick Purge - Pipe Purging Systems
In cases where purging is required to be fast as well as reliable, the Quick Purge Systems can be used.
These systems will typically purge 36" pipe diameters to below 0.1% oxygen in less than 10 minutes and all smaller pipes, correspondingly faster.
Description
Each Quick Purge is covered with heat protective materials on the inside, so that the high temperatures at close proximity to the weld do not damage the devices.
Three hoses are available, one for argon inflation and purge, the second for auxiliary purge and the third for gas exhaust via a purge monitor.
Operation
The system is connected to an argon hose and inserted into the pipe to be welded.
The spinal connection hose is shorter than with other devices, to keep the purged volume to a minimum. The majority of the volume between the two dams, is filled with a special heat resisting collar, to keep the purge time low.
After positioning the system the argon source is opened, the dams inflated to size and the interspace purged.
after a few seconds, the auxiliary purge line can be opened to ensure the fastest possible purge time.
In trials these devices have performed many high speed welds under these conditions.
Sizes from 8inch to 84inch (200mm - 2100mm)
Feedback off the end users of the quick purge have reported savings of up to 83% ! on the purge time!
Saves on purge gas, as the volume needed to be purged is greatly reduced.
This system pays for itself in a few welds!
So why struggle with "make do" systems.

Heat Resistant Pipe Purging Systems for pre-heated pipe welds.
When pre-heated ferric steel alloy pipe joints typically (5% CrMo) and some other types of steel and alloys are welded, particularly for high pressure pipework or for low hydrogen requirements, argon purging at the back of the weld is required. This is to eliminate the risk of coking and oxidation, leading to notching and eventual stress cracking under pressure.
After many years of trials and development, Huntingdon Fusion Techniques Limited has launched a range of variable diameter pipe purging systems.
Description
One model is available for each internal diameter. Each one is variable by approximately +0mm -12mm.
Using the well tried and proven Argweld® Pipe Purging System, the heat resistant version is totally covered in a special heat resistant material, which will withstand temperatures of up to 300 degrees C (572 degrees F) for 24 hours.
Operation
The system is connected to an argon hose and inserted into the pipe to be welded.
The spinal connection hose is long enough for the dams to sit at the outer edge of the pre-heated zone.
After positioning the system the argon is opened, the dams inflated to size and the interspace purged.
The purge will remain on during pre-heat and welding. It is advised for the removal of the systems prior to post-weld heat treatment.
In trials, the devices have performed many welds under these conditions.

The Multi-Exhaust Inflatable Pipe Purge Systems have a number of distinct advantages leading to big cost savings:
Use Less Inert Gas
The volume to be purged is localized. For a typical pipe run, the volume of gas used is less than 2% of that required for a conventional purge.
Faster
The system is quick + easy to install. It can be positioned accurately and the dams inflate instantly. Purging time is a fraction of that required to purge by conventional methods.
Easy to Use
'Inflatable Pipe Purge Systems' simplify the process of inert gas purging, Training is Minimal.
Improved Quality of Welds
Leading to bright, shiny, coke and oxide-free welds very quickly. The process involved is highly reliable. It gives regular, controlled high quality results.
Fast Pay Back
The Argweld pipe Purging System pays for itself in just a few welds.
Fast Payback
The 'Inflatable Pipe Purge System' pays for itself in just a few welds.
Highest Standards
We manufacture to Nuclear Quality with Nuclear approved materials.
High quality circumferential butt welding of pipe to pipe and pipe to fitting requires inert gas to be used inside the bore to prevent oxidation and notching of the root penetration weld bead.
The best system devised for this is the Inflatable Pipe Purge System.
It is quick, reliable and easy to use, the volume of purging required is kept small, resulting in significant savings in both time and the volume of inert gas used.

Pipestoppers™ Inflatable stoppers
INFLATABLE STOPPERS
These versatile inflatable air bags and stoppers are used to accommodate a wide variety of industrial applications, most commonly used for:
Plumbing operations
Ideal for creating an air-tight seal in drainage applications
Low pressure hydrostatic tests
On-site thermoforming of bends in ducting and conduit materials
Fibre-optic construction projects
Concrete Pipe Joint Testing
Debris and Animal Stopping
Weld purging to isolate large volumes in tanks, so minimum volumes are left for argon/nitrogen purging
Features:
Inflatable air bags up to 2,000 mm (80") diameter
Manufactured using a high quality latex inner tube and polyurethane impregnated nylon fabric outer cover
Installed with a length of flexible inflation hose with sealing tap/valve.
Styles:
Cylindrical inflatable stoppers do not 'turn over' in the pipe. They are commonly used for stopping off pipes, particularly where access is difficult. They are frequently used for testing new pipes and drains.
Spherical inflatable stoppers give less contact area than the cylindrical version, but are very useful when access is limited. Since the position of the inflatable stopper in the pipe is not critical, it can be put at any angle. This is particularly useful when inserting into a small opening at the top of a pipe, rather than at the end of the pipe.
Rectangular inflatable stoppers have various applications specifically in air conditioning systems, air ducting and venting.
All sorts of special shapes and sizes have been taken on as specials!

BENCHMIKE 283 - Off-line tube samples ID/OD/Wall Measurement System
For precision ID, OD, and Wall Thickness measurements, simply place a tube sample on the ID/OD/Wall fixture and the BenchMike will calculate all the dimensions. The ID/OD/Wall fixture can also automatically rotate a sample to a pre-defined number of positions for measurements at multiple points around the product. This rotation allows for the calculation of concentricity and ovality of the tube. The graphical user interface has options to view the rotational cross section of the product and a graph that shows deviation or variation at the various rotational degrees of measurement.
Features:
* Measures over tube samples of diameter from 0.075 up to 50mm (depending on fixture used)
* accuracy of +/-0.9micron
Benefits:
1- Ease of use & repeatability from one operator to another
2- Accuracy of measurements thanks to the laser scanning technology
3- User-friendliness of the graphical interface and of the principle of measurement
Several fixtures are offered to measure outside diameters/other dimensions of tubes: V-blocks, rotating mandrels, translation slides...

Hydratron has many years of experience designing and manufacturing hose test rigs to suit many applications.
We can supply proof, burst and impulse test rigs / benches for testing with either gas or liquid at pressures up to 45,000 PSI ( 3,000 Bar )
Single or multi station test manifolds can be fitted mounted within robust safety cabinets. These cabinets are fitted with fully interlocked doors to ensure that pressure cannot be applied to the hoses under test until the doors are fully closed and locked in position.
While simple manually controlled test rigs are readily available for proof testing hoses at local hose distributors, fully PLC controlled machines can also be designed to suit production lines.
Standard instrumentation includes analogue pressure gauges but full data logging facilities can be supplied as an option.

Float-in Bags are fitted with a reinforced front cover and tension lugs. The CR material ensures increased resistance to chemicals. Working lines are secured to the tension lugs using carbine hooks and the pipe sealing bag can be floated into the pipeline without any difficulty.
Only four sizes are needed in order to seal pipe dimensions ranging from 70 mm to 1200 mm (2.8 inch to 47 inch). The float-in bag program is rounded off by a chemical variation in addition to the basic design.
In this case, all metal parts on the float-in bag are made of stainless steel and the integrated inflation hose (10 m/32 ft.) guarantees the corresponding safety distance to the area of danger.
