Why Partners Trust Our Calibration Solutions in New Zealand

Uncompromising Accuracy

Our facilities utilize high-precision digital logging and NATA/ISO traceable equipment to ensure every “set pressure” and “reseat” is documented with mathematical certainty.

Minimal Operational Impact

Whether through our In-Situ (In-Line) Testing technology for Onsite Calibration Services in New Zealand or our rapid-turnaround workshop services for Offsite Calibration Services in New Zealand, we focus on reducing your Mean Time to Repair (MTTR).

Regulatory Peace of Mind

We don’t just test; we certify. Every valve serviced by us receives a comprehensive digital report meeting API 527 and ASME standards, providing you with a transparent audit trail for insurance and safety inspectors.

Total Lifecycle Support

From the initial “As-Found” testing to precision lapping and final “Green Tag” certification, we handle the entire maintenance lifecycle in-house.

Comprehensive Testing Capabilities

Highlight the breadth of your services to show that you are a “one-stop shop” for pressure management, providing comprehensive

Calibration Services

Offline Workshop Testing: Precise calibration in a controlled environment using high-accuracy test benches.
In-Situ / In-Line Testing: Testing valves while they are still in the system (under full load) using hydraulic assist devices to avoid system shutdowns.
Medium-Specific Testing:
- Air/Gas: Using nitrogen or compressed air for safety valves in gas service.
- Liquid/Hydro: Using water for relief valves in liquid service.
- Steam: Testing on live steam to ensure accurate “pop” and reseat behaviour at operating temperatures.

Compliance & Standards

Trust is built on certifications. Ensure this industry standards are front and centre:

API RP 576: Inspection of Pressure-Relieving Devices.
API Standard 527: Seat Tightness of Pressure Relief Valves.
ASME Section I & VIII: Boiler and Pressure Vessel Codes.
National Board “VR” Stamp: If applicable, highlight your authorization to repair and stamp valves.
ISO 9001:2015: For quality management systems.

The Full-Service Lifecycle

Inspection: Visual check for corrosion, pitting, and mechanical damage.
Pre-Test: “As-Received” pop test to document performance before servicing.
Overhaul: Complete disassembly, cleaning (including Oxygen Cleaning), and parts replacement.
Machining: In-house lapping of nozzles and discs to restore OEM-spec finishes.
Certification: Issuing traceable calibration certificates and “green tag” service labels.

Comprehensive Supply Capabilities

Mobile & On-Site Solutions

For many industries, the biggest “pain point” is shipping heavy valves. Highlight your logistics:

Mobile Service Centres: Fully equipped 20ft or 40ft containerized workshops that travel to the site.
Turnaround/Shutdown Support: 24/7 dedicated teams to handle high-volume valve testing during scheduled outages.
Asset Management: Online portals where clients can download their test reports and track upcoming calibration dates.
