At Sarovar Tube Industries quality is treated as a measurable outcome rather than a claim. Every heat that enters our facility is analysed, every finished piece is inspected, and every consignment leaves with documentation that ties it back to the test results that qualified it.
Our commitment: to supply material that performs exactly as specified, supported by documentation that stands up to the scrutiny of any inspector, in any market, at any time. No consignment leaves our facility without a documented chemical, mechanical, dimensional and visual inspection record traceable to its heat number.
Sarovar Tube Industries operates under a certified Quality Management System complying with international standards. Copies of our certificates are not published for download — they are shared for viewing on request with customers and inspection agencies.
Sarovar Tube Industries • Mumbai, India
Certified for compliance with international standards for the Manufacture, Export, Import & Stocking of Carbon Steel, Stainless Steel & Alloy Steel, Pipes, Tubes & Industrial Raw Material.
We welcome third party and customer inspection at any stage of manufacture. Where a project requires an independent signature on the test report, we coordinate the visit and release the material only after the inspector has signed off.
Manufacture and supply material that consistently conforms to ASTM, ASME, EN, DIN, JIS and customer specifications, without substitution.
Chemistry is confirmed on every heat by optical emission spectrometry and positive material identification before it enters stock.
Full traceability from heat number through cutting, forming, heat treatment and despatch, recorded against the order.
No consignment is released without documented mechanical, dimensional and visual inspection signed by an authorised inspector.
Third party and customer inspection is welcomed at any stage of manufacture, not only at final inspection.
Processes are reviewed and improved against customer feedback, audit findings and non-conformance analysis.
The following tests are carried out in house or through accredited laboratories, depending on the specification and the customer's inspection requirements.
| Test | Method | Purpose |
|---|---|---|
| Chemical Analysis | Optical emission spectrometry on every heat | Verify conformance to grade chemistry |
| Positive Material Identification | Portable XRF / OES analyser | Prevent grade mix-up before despatch |
| Tensile Test | Universal testing machine | Confirm tensile, yield and elongation |
| Impact Test | Charpy V-notch, down to -196 degrees C | Qualify low-temperature toughness |
| Hardness Test | Brinell, Rockwell and Vickers | Verify heat treatment condition |
| Hydrostatic Test | Pressure testing rig | Confirm leak tightness under pressure |
| Ultrasonic Test | Contact and immersion UT | Detect internal discontinuities |
| Radiographic Test | X-ray and gamma radiography | Examine welds and heavy sections |
| Dye Penetrant / MPI | Liquid penetrant and magnetic particle | Detect surface breaking defects |
| Intergranular Corrosion | ASTM A262 practices | Qualify corrosion resistance |
| Flattening / Flaring / Bend | Mechanical press testing | Confirm ductility and soundness |
| Dimensional Inspection | Calibrated gauges and CMM | Verify tolerance compliance |
Every consignment is despatched with a complete document pack. Additional certificates are prepared on request at the time of order.
Standards are the common language between us, our customers and inspection agencies. Every pipe, tube, fitting, flange, bar, sheet and plate we supply is produced, tested and certified against the international and national standards below — and the governing standard is printed on every mill test certificate, so you know exactly what you are receiving.
