Quality Assurance
Rigorous quality standards at every step — from raw material to finished product delivery.
Quality is Not Optional
At Accurate Tube Industries, quality is embedded into every step of our sourcing, stocking and quality-checking process — not as an afterthought, but as the foundation of every decision. Our QC program ensures each tube meets or exceeds specified standards.
We operate a comprehensive quality control program covering incoming raw material verification, in-process monitoring at all critical stages, final product inspection, and outgoing checks before dispatch. Our QC team uses calibrated instruments and follows documented inspection procedures.

Incoming steel coils verified for chemical composition, mechanical properties, thickness tolerance, and surface condition. Material test reports from primary steel mills reviewed and archived.
OD/width, wall thickness, straightness, and length verified at multiple stages using calibrated gauges. Out-of-tolerance tubes immediately removed from the production stream.
All finished tubes inspected for surface defects, weld seam quality, scale, pits, laps, cracks, and unacceptable surface conditions. Only passing tubes proceed to packaging.
Industrial pipes for pressure applications undergo hydrostatic testing at specified pressures per IS 1239. Each pipe pressurised, held, and inspected for leaks before approval.
Tensile strength, yield strength, elongation, bend test, and flattening tests on production samples to verify mechanical properties comply with grade specifications.
Chemical composition verified through spectrometric analysis — critical for SS products where exact alloy content determines corrosion performance.
Final check before loading: correct product, quantity, dimensions, and labelling. Test certificates, delivery documents, and packing lists prepared and handed to transporter.
Post-delivery follow-up to confirm product quality and satisfaction. Customer feedback documented and used to drive continuous improvement.
