Philosophy

Quality is Not Optional

At Accurate Tube Industries, quality is embedded into every step of our manufacturing 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.

QA Process

Quality Control Steps

Raw Material Inspection

Incoming steel coils verified for chemical composition, mechanical properties, thickness tolerance, and surface condition. Material test reports from primary steel mills reviewed and archived.

Dimensional Verification

OD/width, wall thickness, straightness, and length verified at multiple stages using calibrated gauges. Out-of-tolerance tubes immediately removed from the production stream.

100% Visual Inspection

All finished tubes inspected for surface defects, weld seam quality, scale, pits, laps, cracks, and unacceptable surface conditions. Only passing tubes proceed to packaging.

Hydrostatic Testing

Industrial pipes for pressure applications undergo hydrostatic testing at specified pressures per IS 1239. Each pipe pressurised, held, and inspected for leaks before approval.

Mechanical Testing

Tensile strength, yield strength, elongation, bend test, and flattening tests on production samples to verify mechanical properties comply with grade specifications.

Chemical Analysis

Chemical composition verified through spectrometric analysis — critical for SS products where exact alloy content determines corrosion performance.

Pre-Dispatch Inspection

Final check before loading: correct product, quantity, dimensions, and labelling. Test certificates, delivery documents, and packing lists prepared and handed to transporter.

Customer Satisfaction Review

Post-delivery follow-up to confirm product quality and satisfaction. Customer feedback documented and used to drive continuous improvement.
