Non-Destructive Testing

NDT equipment for structural integrity and weld inspection in Pakistan

Non-destructive testing lets engineers evaluate welds, structural concrete and steel components without cutting, coring or otherwise damaging the element under test. GGC supplies ultrasonic flaw detectors, ultrasonic thickness gauges, Schmidt test hammers, rebar locators and cover meters, coating thickness gauges and related NDT instruments to inspection companies, fabricators, testing laboratories and infrastructure contractors across Pakistan.

Whether you are qualifying welds on a pressure vessel, mapping reinforcement before coring a bridge deck or verifying concrete strength in an existing structure, our engineers help you match the instrument, probes and accessories to the inspection standard and geometry involved.

Choosing the right NDT instrument

NDT performance lives in the details. We confirm before quoting:

• Material and geometry under inspection: welds, plate, pipe or concrete elements
• Measurement ranges and probe selection for ultrasonic work
• Data logging, storage and reporting for client documentation
• Compliance with the relevant inspection procedure or standard
• Battery life and field portability for site campaigns
• Calibration support and spare probe availability

Instrumentation for concrete, steel and coatings

For concrete evaluation we supply rebound (Schmidt) hammers plus rebar locators and cover meters that map reinforcement before drilling or coring. For steel and weld inspection we supply ultrasonic flaw detectors with calibrated probes, and thickness gauges for corrosion surveys. For protective coatings, gauges verify paint and galvanising thickness on structural steelwork — the three pillars of a practical NDT kit.

Support, calibration and inspector training

Instruments are delivered with manufacturer documentation, and we provide calibration support to keep results traceable to your quality system. Our engineers train your inspectors on setup and interpretation, and remain available for application advice throughout the instrument's working life.

Applications across Pakistan's inspection industry

NDT equipment supplied by GGC is working today across Pakistan's fabrication yards, power and process plants, bridge maintenance programmes and building-inspection firms. Weld inspection on structural steel and pressure equipment, thickness surveys on storage tanks and pipelines, and concrete evaluation in ageing buildings are the three workloads we see most.

Typical programmes include ultrasonic weld scanning to written procedures, wall-thickness surveys ahead of fitness-for-service assessment, rebound hammer screening of concrete elements, rebar mapping before coring or drilling, and coating thickness verification on galvanised and painted steelwork. Inspection contractors value that a single supplier covers all of these, with accessories, calibration support and one point of technical contact.

Building a reliable NDT capability

Instruments are one part of dependable inspection. Reliable programmes also need calibration blocks matched to the material under test, a written procedure that fixes probe angles, couplant and scan patterns, and inspectors trained to record what the instrument shows rather than what the schedule hopes. We supply the reference blocks and couplants alongside the instruments, and help clients align their paperwork with the equipment actually in the kit.

Consumables matter more in NDT than most buyers expect: probe wear, cable failures and battery degradation erode capability quietly. Our after-sales support stocks and sources the consumables your programme uses, so an inspection campaign is never paused waiting for a replacement part.

Requesting a quotation

To request a quotation, share the materials, geometries and procedures you inspect. We will propose instruments, probes and accessories that satisfy your written practice, quote options at different price points, and include the training your inspectors need.
