We control the full hygienic piping lifecycle, from direct-mill material sourcing to certified installation and audit-ready handover, so purity and traceability are never left to a subcontractor chain.
Automated orbital welding produces uniform, repeatable joints with 100% back purging — eliminating oxidation and crevices where bacteria could harbour.
Complete hygienic process line erection built for full drainability and clean-in-place operation, engineered to 3-A, EHEDG and FDA guidance.
Prefabricated spools, skids and manifolds assembled in controlled shop conditions — tighter tolerances, cleaner welds and faster, lower-risk site handover.
Electropolished ASTM A270 tube and passivated surfaces validated to ≤0.6µm Ra — the mirror finish that resists fouling and supports validation.
Direct-mill supply of stainless grades with full documentation — no middleman markups, no traceability gaps between mill and installed weld.
Every project closes with a complete, audit-ready dossier — the evidence your QA and validation teams need to release the system.
Material selection is where hygienic performance is won or lost. We match grade to duty — balancing corrosion resistance, weldability and cost — and back every batch with 3.1 mill certification.
For Qatar's coastal, chloride-heavy atmosphere, 316/316L is our default for corrosive and outdoor service; its molybdenum content resists the pitting that undoes lesser grades.
Grade selection, standards mapping and direct-mill procurement with 3.1 certs.
Orbital-welded spools and skids prefabbed to tight tolerance off-site.
Field erection with 100% back-purged welds and weld-map traceability.
Passivation, boroscopy, hydro-test and a full audit-ready turnover pack.
