years of experience

Back when GTEC was a tight crew working out of a single office, we had one rule: if a reading leaves this lab, it will be right. That same stubbornness about accuracy is still here and it just travels further now . Today, 50+ specialists across five branches carry that original promise forward at a much bigger scale, covering everything from torque wrench calibration to full-bore pipeline hydrotesting across Saudi Arabia.

Every result is traceable to IAS and SAAC reference standards

Accuracy comes first always, even when the schedule is tight

Mobilization that never cuts corners we bring the lab to your site

Rigorous internal audits that exceed ISO/IEC 17025 requirements

Wherever your project sits in the workshop, on a rig deck, or in the middle of desert sand GTEC puts the right specialist, the right equipment, and the right paperwork in front of your inspector.

Valve Testing

Manual valve seat-and-shell testing, control valve calibration, relief valve set-point verification, hydrostatic testing up to 20,000 PSI, and hose testing on our 59,000 PSI bench. Our 250-ton horizontal test bench handles what most shops cannot even fit through their doors.

Inspection

Lifting gear and equipment inspection per LEEA and ASME, general machinery functional tests, SCBA hydrotesting and Grade D air refilling, compressed air quality analysis, and hydrotest water chemistry verification. Third-party certificates that Aramco and SABIC auditors sign off on.

Calibration

Precision calibration services designed to ensure accuracy, compliance, and reliable equipment performance. GTEC delivers certified testing, inspection, and measurement solutions that meet international industrial and safety standards.

Hydro Testing

High-pressure shell and seat testing up to 20,000 PSI conducted with extreme precision. We utilize advanced digital chart recorders to provide a verifiable "fingerprint" of structural integrity, ensuring all pressure-retaining assets meet strict ASME, API, and Aramco safety codes.

Hose Testing

Full-cycle validation performed on our specialized 59,000 PSI test bench. From visual inspection of end-fittings to high-pressure burst testing, we certify hydraulic, chemical, and industrial hoses to withstand the harshest offshore environments. Each hose receives a unique tag.

Water Testing

Comprehensive on-site analysis of hydrotest water to identify chlorides, pH imbalances, and corrosive elements. We ensure your testing medium remains within the strict chemistry limits required by SABIC and Aramco, protecting high-performance

Air Quality Testing

Professional Grade D breathing air analysis and compressed air quality verification. Our technicians conduct rigorous testing for CO, CO2, oil mist, and moisture content to ensure total compliance with OSHA and international safety standards.

Instrumentation

Full-scale loop calibration and troubleshooting for transmitters, switches, and controllers. Whether monitoring flow, level, or analytical data, we ensure your control room reads 100% true under load. Our services minimize operational downtime and eliminate the risk of false system.

Manifold Supply

Supply of 4-way, 6-way, and custom-configured test manifolds designed for immediate field deployment. Every unit is pressure-rated, hydro-tested, and color-coded for safety compliance. Available for sale or rental to support complex hydrotesting, gas distribution

From wellhead to warehouse, from turbine hall to server room GTEC’s calibration and inspection teams are already embedded in the sectors that keep the Kingdom running.

Oil & Gas

Upstream, downstream, and everything in between.

This is where GTEC cut its teeth. Aramco upstream drilling support, SABIC downstream refinery shutdowns, cross-country pipeline hydrotesting, and offshore rig calibration on jack-ups and FPSOs.

Power & Industrial Plants

From boiler rooms to server racks.

Power generation facilities, petrochemical complexes, water treatment plants, and the new wave of AI data centres across the Kingdom — each one depends on instruments that read true under load.

Certified technical support for the Kingdom’s harshest environments.

From the heat of the Empty Quarter to the corrosive humidity of the Arabian Gulf, GTEC delivers inspection and calibration where the environment is most unforgiving.

Construction & Infrastructure

Precision on the ground floor of mega-projects.

Mega-scale construction sites need calibrated welding machines, verified torque wrenches, and surveying instruments that hold true across kilometres of layout.

We handed GTEC a pile of 200+ instruments at 4 PM during a plant turnaround. By 6 AM the next morning, every single one was calibrated, tagged, and the certificates were sitting in our inbox. Their night crew gave us a full day’s head start on commissioning. Brilliant turnaround.

Project Controls Manager

Major EPC Contractor — Ras Tanura

What sold me on GTEC was the valve shop. We brought in a 24-inch gate valve and they had it on the bench the same week. The hydrotest certificate passed Aramco QA/QC review clean — first submission, accepted straight away. That kind of bench capacity and documentation quality is exactly what we needed.

Mechanical Integrity Lead

Petrochemical Maintenance Company — Al Jubail

I have used GTEC for SCBA refilling, lifting inspection, and pressure calibration across three different Aramco projects. Same quality every time. Same documentation format. Same faces showing up. That consistency is what keeps us coming back.
