Heavy industry does not get a second chance at getting it right. A weld that fails, a component that does not meet spec, or an installation that deviates from the drawing can cost far more to fix after commissioning than it would have cost to catch during inspection.
TNV Inspection Division provides UAF-accredited industrial inspection services across India, under ISO/IEC 17020:2012 (Accreditation No. 5241222IB04). As a Type A inspection body, we hold no commercial interest in the equipment manufacturer, the EPC contractor, or the project owner. Our inspectors verify what is actually built, fabricated, or installed against what was specified.
We work with heavy industry manufacturers, EPC contractors, and public sector undertakings (PSUs) across steel, power, chemicals, oil and gas, and infrastructure sectors.

What is Industrial Inspection?
Industrial inspection is the independent verification of materials, equipment, fabrication work, and installation activity at industrial sites, checked against engineering drawings, purchase order specifications, and applicable codes and standards.
Unlike a single-point inspection such as a pre-shipment check, industrial inspection often spans a project’s full lifecycle — from raw material verification, through in-process fabrication checks, to final testing and commissioning support. It typically involves:
- Material verification — confirming raw materials and components meet specified grades and certifications
- Dimensional and visual inspection — checking fabricated components against approved drawings
- Welding and NDT inspection — verifying weld quality using ultrasonic, radiographic, magnetic particle, or dye penetrant testing
- Equipment performance checks — functional and performance testing of industrial equipment before dispatch or commissioning
- Installation and stage-wise inspection — verifying that on-site installation matches design intent at defined project milestones
Why Industrial Inspection is Critical for Indian Industry and EPC Projects
- PSU Tenders and EPC Contracts Frequently Mandate It Public sector undertakings and large EPC contracts routinely specify third party inspection as a tender condition, particularly for equipment procurement, fabrication packages, and installation milestones. Non-compliance can mean rejected equipment or delayed project handover.
- Rework After Installation is Far More Expensive Than Catching Issues Early A fabrication defect caught at the workshop stage costs a fraction of what it costs to fix after the component has been transported, installed, and integrated into a live plant or project.
- Heavy Industry Projects Involve Multiple Vendors and Long Timelines Large industrial projects often involve dozens of fabrication vendors and equipment suppliers working in parallel over months or years. Independent, stage-wise inspection gives project owners and EPC contractors a consistent, unbiased view of quality across every vendor — something that is hard to maintain relying on vendor self-certification alone.
- Safety and Regulatory Exposure Industrial equipment and installations that fail to meet code requirements create real safety risk and regulatory exposure. Independent inspection provides a documented record that due diligence was carried out.
TNV's Industrial Inspection Services
- Material and Component Verification Checking raw materials, castings, forgings, and fabricated components against material test certificates and purchase specifications before further processing.
- Welding and NDT Inspection Non-destructive testing including ultrasonic testing (UT), radiographic testing (RT), magnetic particle inspection (MPI), and dye penetrant testing (DPT), along with visual weld inspection against relevant codes such as ISO 3834.
- Dimensional and Visual Inspection Verification of fabricated components and assemblies against approved drawings, tolerances, and specifications.
- Equipment Performance and Functional Testing Pre-dispatch inspection of industrial equipment — pumps, valves, pressure vessels, tanks, and electrical equipment — including functional checks and hydrostatic testing where applicable.
- Stage-wise Project Inspection Milestone-based inspection throughout fabrication, transportation, and installation phases of long-duration industrial and infrastructure projects, so issues are identified and corrected before they compound.
- Documentation and Regulatory Review Review of technical drawings, quality plans, material test certificates, and inspection and test plans (ITPs) for completeness and conformance ahead of approvals or dispatch.

Our Industrial Inspection Process
- Step 1 — Scope and Standards Confirmation You share project drawings, purchase specifications, applicable codes, and the inspection milestones required. We confirm scope and provide a cost estimate.
- Step 2 — Inspector and NDT Resource Assignment We assign inspectors experienced in your equipment or project type, along with any specialised NDT technicians required for the scope.
- Step 3 — Stage-wise Inspection Our inspectors conduct inspection at each agreed milestone — raw material stage, in-process fabrication, pre-dispatch, and installation — verifying conformance at every step.
- Step 4 — Inspection and Test Reports You receive detailed reports for each milestone, including findings, photographic evidence, NDT results where applicable, and any non-conformances identified.
- Step 5 — Follow-Up and Closeout Verification Where non-conformances are found, we support corrective action verification and, where required, re-inspection before final acceptance or commissioning.

Frequently Asked Questions(FAQ)
What is industrial inspection?
Industrial inspection is the independent verification of equipment, materials, fabrication, and installation work at industrial and infrastructure sites against engineering drawings, purchase specifications, and applicable codes and standards. It covers everything from raw material checks to final commissioning.
Which industries need third party industrial inspection in India?
Heavy industry, oil and gas, power generation, steel and metals, chemicals and petrochemicals, and EPC-driven infrastructure projects most commonly require third party industrial inspection. Many PSU tenders and large EPC contracts specify it as a mandatory tender condition.
What does TNV check during an industrial inspection?
Depending on scope, TNV checks raw material certification, dimensional accuracy, welding quality, NDT results, equipment performance, installation conformance to drawings, and safety compliance at each project milestone.
How much does industrial inspection cost in India?
Cost depends on the equipment or project type, site location, inspection duration, and whether NDT or specialised testing is required. Contact us at info@tnvib.com for a specific quote — initial enquiries are free.
Can TNV inspect ongoing EPC or PSU projects?
Yes. TNV provides stage-wise inspection throughout a project lifecycle, not only at project completion, so EPC contractors and PSUs can catch and correct issues at each milestone rather than at the end.
