inspection & qa/qc.

Technical integrity, welding & NDT.

NDT Level 3 consultancy to ISO 9712 and CSWIP 3.2 certified welding inspection. From procedure qualification (WPS/PQR) to final non-destructive testing, on critical equipment and to ASME, PED and API.

What we do.

Non-destructive testing is where the quality of a plant stops being an intention and becomes a measurable fact.

Our work sits before and after the physical execution of the test. Before: defining the extent of testing according to service class, writing and approving procedures, setting acceptance criteria consistent with the construction code, qualifying and verifying the competence of Level 1 and 2 operators. After: technical review of reports, assessment of doubtful indications, handling of non-conformities and any concession requests, decisions on the repair and on the repair procedure.

Responsibility for the judgementWe do not just issue a certificate. When an indication is at the limit of acceptability, someone has to decide whether to repair it, accept it with a documented concession or reject it. That decision needs formal technical authority, not an opinion.

Procedure qualification is the second pillar. We write pWPSs and WPSs, manage the qualification test coupons and their certification (PQR), and qualify welders (WPQ) on the validity ranges the job actually needs. It is the document on which the acceptability of every site weld rests, and the first thing a third-party inspector reads.

TSIE does not sell equipment and has no agency agreements with manufacturers. When we give a judgement on a supplier, a material or a repair, it carries no upstream conflict of interest.

Scope of work.
