At VAPQ Real Defect, we specialize in Vacuum Testing services designed to ensure precision, consistency, and compliance with global weld-integrity standards. Vacuum box testing is essential for detecting surface-breaking leaks, cracks, and porosity in welds, tank bottoms, and plate joints.
Each inspection is carried out using certified vacuum boxes, calibrated gauges, and approved testing media in full accordance with ASME, API, ASTM, and ISO standards to guarantee accurate leak detection and repeatable performance.
We support fabrication shops, tank manufacturers, refineries, and maintenance teams by providing fast, reliable vacuum testing for storage tanks, vessels, pipelines, structural plates, and repair welds.
