We enforce rigorous welding inspections and material checking procedures to protect piping pressure integrity and ensure structural strength.
All stainless steel welding procedures are qualified under ASME Section IX (for pressure pipes & vessels) and AWS D1.6 (for structural welding). Detailed WPS, PQR, and welder credentials are ready for customer audit review.
We maintain 100% material traceability. Mill Test Certificates (MTC) matching EN 10204 3.1 standards are recorded for every batch of SS304/SS316 plates, piping, and filler wires to prevent alloy contamination.
Our welding inspection team includes certified ASNT Level II inspectors. We coordinate comprehensive Dye Penetrant Testing (DPT), Radiographic Testing (RT), ultrasonic testing (UT), and hydrostatic pressure tests.
Every B2B contract is closed out with a complete documentation record folder, containing all tests, welder logs, material trace sheets, and inspection sign-offs:
For high-purity piping (like drinking water filtration plants and hygienic manufacturing), even small pinholes or rough surface cracks can harbor bacteria or cause corrosion under stress.
Our QA/QC program enforces inert gas purging (back-purging) during TIG welding to block internal joint oxidation (referred to as "sugar formation"). After welding, pickling and passivation chemically remove weld heat tints and restore the stainless steel's rust-resistant passive film.
We comply with the latest **Qatar Construction Specifications (QCS)**, civil defense requirements, and municipal directives for structural fabrications.
