Hydratight presents in-line weld testing and isolation packages designed to reduce system downtime during maintenance and increase worksite safety by minimising pressure test volumes.


Available throughout Australasia and the Asia-Pacific from global joint security specialist Hydratight, the full turnkey testing packages save time and reduce costs by limiting the test area only to new welds or welded components tested during routine maintenance and maintenance shutdowns such as Christmas/New Year. 


Localised pressure testing verifies the integrity of a welded or formed joint or flange installation/weld made on a piping system. Typically these are made as a repair or modification of part of a process piping system, which is undertaken during plant shutdown activities.


Hydratight provides certified and experienced technicians to perform the job safely, delivering a first-class maintenance solution for facility assets to operators as a full turnkey testing package. Hydratight's qualified and professional technicians provide a safe, reliable and cost-effective means for the localised pressure testing of piping.


Technicians insert the weld test tool into the pipe or equipment component to provide a fast and efficient method of verifying the integrity of butt welds, joints or other welded pipe components.


Featuring a double block and bleed isolation, Hydratight's in-line weld test tools provide a verified vapour barrier once set in position, allowing hot work activities to take place safely on-site. The weld is tested by repositioning the same tool over the weld area. The weld test is typically undertaken using water as the test medium, but can be undertaken using inert gas where necessary. 


The test is normally a strength test of the joint at 1.5 times the design pressure, but can also be used as a means for leak testing, typically undertaken at 1.1 times the design pressure.


Given the multiple variants in piping in terms of wall thicknesses and flange configurations, Hydratight offers a broad range of test tools to accommodate all requirements. 


Hydratight also supplies an extensive range of lightweight aluminium tools designed for light, fast and flexible use.
