Inspection Services
Visual, dimensional, and non-destructive inspection of OCTG and drilling equipment — in-house and at client or rig site — to ASNT, API, and DS-1 standards
Elmoj provides a comprehensive range of tubular and equipment inspection services, available both at our facility in Tripoli and as a mobile service at client yards, ports, or rig sites. All inspection is conducted to internationally recognized standards, with full documentation and traceability provided on every job.
Our in-house inspection capability is backed by our full API and ISO certification portfolio. Where specialist NDT techniques are required beyond our in-house capability, we engage qualified and accredited third-party subcontractors under our quality management system.
