Policy
Manufacture to the agreed specification, on the agreed date.
Pipes meeting specified, statutory and regulatory requirements — with continual improvement of the QMS and product range.
Quality
Nothing ships without proof.
Each joint is traceable to its coil, heat number, welder and inspection record — and leaves the yard with a full dossier.
Quality
Nothing ships without proof.
NPC has supplied a large number of projects in Saudi Arabia and the wider Middle East since 1980 — and every one of them was backed by a full inspection dossier.
01
Quality systems
ISO 9001 and API Q1 / ISO TS 29001 process approach — documented, measured and continually improved.
02
Traceability
Each joint is traceable to its coil, heat number, welder and inspection record.
03
Inspection
Ultrasonic, radiographic and hydrostatic testing before any pipe leaves the yard.
04
Approvals
API 5L and API 2B monograms, TUV ISO 9001, and approved supplier to national operators.
Capabilities
Quality is planned at contract review.
Deviations are settled before production. Training with Sumitomo Metal Industries and stock of popular coils and plates support short-notice orders.
Release
QA Manager signs every certificate.
Final inspection is independent of production. Product does not ship until planned tests are complete and the inspection certificate is approved.
