Testing & Inspection

Inspection, Verification & Compliance

Taiyo Holding performs technical inspections and testing on industrial plants, equipment, infrastructures, and systems to verify their compliance, functionality, and performance standards. Through precise control activities, we identify potential deficiencies and ensure that corrective measures are implemented before issues become critical or irreversible. Continuous project monitoring also guarantees full adherence to quality requirements, safety standards, and contractual specifications, ensuring that every asset operates reliably and efficiently from construction to commissioning.

Taiyo delivers inspections to ensure operational control and compliance.

NON DESTRUCTIVE TESTING (NDT)

Radiographic tests (ASTM/EN), ultrasonic tests (ASTM/EN), checks with magnetic powders (ASTM/EN), Penetrating liquid tests (ASTM/EN) and P.M.I tests.
ACOUSTIC EMISSION

Acoustic emission is a phenomenon of energy release in the form of transient elastic waves within a material under stress. Detection and analysis of the signals provides information about anomalies in the stress field. The detection is performed by a piezoelectric sensor attached to the structure.
CERTIFICATION OF WELDERS UNDER ISO 17024

We carry out the certification of people under accreditation 17024 for the qualification of welders, in accordance with different standards, such as EN ISO 9606-1, EN ISO 9606-2 or EN ISO 14732, among others.
QUALITY CONTROL IN THE MANUFACTURE OF SUPPLIES

Product and production line inspections allow you to check quality at different stages of the production process. Inspecting your product and production facilities is an effective way to prevent quality problems and supply chain disruptions down the line. Industry 4.0 offers different ways to save money with production monitoring, preventive maintenance of equipment but also real-time quality control. Quality management standards are there to guide you and THG can assist you in the inspection of your production facilities, allowing you to save time and be more productive
