Traditional methods of hydrostatic testing demand that you shut down and pressurise large tracts of your system. This is a costly exercise that often halts production for many hours at a time – impacting the overall productivity of your operation and ultimately reducing your organisation's bottom line.
It's also relatively high risk procedure, particularly if you're pressurising an older system. Conducting a 1.5 times design pressure test on mature assets could overstress the system resulting in damage leading to stress fractures or leaks.
Key Benefits
- Straightforward installation and operation
- Hydraulically activated
- Verify the integrity of new or existing welds in minutes
- Large-section, high-quality elastomer seals
Case Study - Comprehensive Shutdown Support Services For A North Sea Platform
Alongside localised testing and hot work barriers, STATS Group supplied on-site machining services to expedite routine maintenance work and minimise downtime during the planned shut down of a North Sea platform.
Webinar - Maximising Shutdown Efficiency To Minimise Risk And Downtime
This 40 minute webinar will show you how to enhance safety and minimise unnecessary downtime using industry-leading technologies like hot work barriers and localised weld testing tools.
Weld Test Tools
In-Line Weld Test tools
Designed to provide a fast and efficient method of verifying the integrity of butt welds, joints or other welded pipe components, our in-line weld test tools allow you to de-risk weld test procedures, and significantly reduce downtime by removing the need to shut down, flood and then de-water large sections of your system.
Key Features
- Simple, straightforward installation and operation
- Installed and activated in a matter of minutes
- Large-section, high-quality elastomer seals
- Leak-tight seal, even in pitted pipework
- Ample radial clearance to accommodate common obstructions
- Robust construction ensures years of trouble free operation
- Suitable for use with most test mediums (liquid or gas)
Hydraulically Activated Over 2" Quick & convenient weld testing
Our In-Line Weld Test Tools can be deployed pre-hot work operations to provide a verified atmospheric barrier adjacent to the hot work source (only where containment is maintained at atmospheric pressure). Once positioned at location and activated these tools provide a verified vapour barrier allowing hot work activities to safely take place.
Our in-line weld test tools are suitable for installation in horizontal, vertical or inclined piping systems and use high-performance elastomer seals, designed to provide excellent radial expansion and relaxation properties over many operating cycles.
In fact, every effort has been made to ensure that our in-line weld test tools are robust enough to withstand repeat use in the harshest environments – so that operators and contractors can rely on them to perform time and time again. Irrespective of whether you deploy them yourselves or draw on our expertise to carry out a weld test, you can be confident that our tools will perform.
It's also worth noting that we design our weld test tools with ample radial clearance, to accommodate common internal obstructions like weld beads, ovality, and similar irregularities. The aim here was to create versatile and adaptable tools that could be used to test weld integrity on any oil and gas pipeline.
Our in-line weld test tools have been deployed to test the integrity of thousands of welds, using a vast range of liquid or gas test medium.
Weld Test Tools
Flanged Weld Test Tools
Designed to enable localised pressure testing on new or existing flange welds, our flanged weld test tools are cost-effective, reliable, and significantly reduce the downtime associated with routine tests. Our flanged weld test tools are suitable where space to deploy an inline tool is limited or to accommodate a change in pipework internal diameter. Flanged weld test tools are available in a range of sizes compatible with common pipe schedules and flange types / sizes.
Key Features
- Robust, single seal and flange configuration
- Simple, straightforward installation and operation
- Hydraulically activated in a matter of minutes
- Large-section, high-quality elastomer seals ensure a leak-tight seal
- Designed with ample radial clearance
- Suitable for use with most test mediums (liquid or gas)
- Years of trouble free operation even in the harshest environments
Hydrostatic Test Flanged Weld Test Tool
Our weld test tools are a versatile option that can be configured to suit multiple applications, including scenarios where a hydrotest is needed on a butt weld between a flange and a welded fitting, such as an elbow or tee.
They make good use of high profile elastomer seals that provide excellent radial expansion and a strong seal on even the most pitted or corroded pipework. They're also designed to accommodate common internal obstructions like weld beads, ovality, and similar irregularities that alternative solutions are unable to accommodate.
Like all STATS Group products, they are built to withstand repeat use in the most hazardous environments, and are suitable for installation in horizontal, vertical and inclined piping systems.
More importantly, they are available as both product and service, depending on the needs of our clients, and can be deployed to any location within 24-48 hours. If you're searching for a field-proven alternative to traditional methods of hydrostatic testing, we'd strongly encourage you to reach out to our team. We'll be happy to talk through your requirements and verify that a STATS weld test tool will be a good fit for your hydrostatic testing requirements.
