A storage tank holding a hazardous chemical, or a process line running under pressure, gives you very little warning before something goes wrong. In this industry, independent inspection is not a paperwork exercise — it is one of the few checks standing between normal operation and a serious incident.
TNV Inspection Division provides UAF-accredited third party inspection services for chemical and petrochemical facilities across India, under ISO/IEC 17020:2012 (Accreditation No. 5241222IB04). As a Type A inspection body, we hold no commercial stake in the plant operator, EPC contractor, or equipment supplier. Our inspectors verify materials, fabrication, installation, and testing against the applicable technical standards.
We work with chemical manufacturers, petrochemical plant operators, EPC contractors, and storage terminal operators across India’s chemical and petrochemical sector.

What is Chemical and Petrochemical Inspection?
Chemical and petrochemical inspection is the independent verification of materials, fabrication, installation, and testing of process plant equipment, storage tanks, piping, and safety systems against applicable technical codes and regulatory requirements.
Given the hazardous nature of the materials involved, inspection in this sector is typically stage-wise and equipment-specific, covering:
- Material verification confirming plate, pipe, and fitting materials meet specified grades and chemical compatibility requirements
- Storage tank inspection verifying fabrication, welding, foundation, and testing of tanks used to store hazardous or flammable chemicals
- Pressure vessel and piping inspection welding inspection and NDT (UT, RT, MPI) of process vessels and piping systems
- Safety and relief system verification checking pressure relief valves, flame arrestors, and other safety-critical equipment
- Hydrostatic and pressure testing witnessing pressure tests on tanks, vessels, and piping before commissioning
- Statutory and pre-commissioning inspection verifying compliance with PESO licensing requirements before a facility or storage installation is put into service
Why Chemical and Petrochemical Inspection is Important in India
- PESO Regulates Hazardous Storage and Handling The Petroleum and Explosives Safety Organisation (PESO) requires third party inspection and certification support for the storage and handling of petroleum products, compressed gases, and hazardous chemicals. This is a statutory requirement, not an optional quality step, tied directly to licensing.
- Gujarat and Maharashtra’s Chemical Clusters Are Expanding As chemical, plastics, and pharmaceutical manufacturing clusters in Gujarat and Maharashtra continue to grow, the volume of new plant construction and storage installation requiring independent inspection has increased substantially. Consistent, qualified inspection capacity is essential to keep pace with this growth without compromising safety.
- A Missed Defect Carries Severe Consequences A weld defect in a storage tank, a faulty relief valve, or an undetected material incompatibility can lead to leaks, fires, or toxic releases — often with little warning. Inspection at the fabrication and installation stage is far cheaper and safer than dealing with a failure once the facility is operational.
- Operators Need a Documented, Independent Record Whether for PESO licensing, CPCB compliance, insurance purposes, or internal safety assurance, operators need an independent, dated record showing that equipment met specification at each stage — something self-certification by the fabricator or EPC contractor cannot provide with the same credibility.
TNV's Chemical and Petrochemical Inspection Services
- Storage Tank Inspection Inspection of storage tanks for hazardous and flammable chemicals, covering material verification, welding and NDT, foundation and structural checks, and testing prior to commissioning.
- Process Piping and Pressure Vessel Inspection Verification of pressure vessel and process piping fabrication, including material certificates and weld inspection using UT, RT, and MPI methods against relevant codes.
- PESO Compliance Support Inspection support aligned with PESO’s licensing framework for storage and handling of petroleum products, compressed gases, and hazardous chemicals, helping operators demonstrate compliance readiness.
- Safety and Relief System Verification Inspection of pressure relief valves, flame arrestors, and other safety-critical systems to confirm they are correctly specified and installed.
- Hydrostatic and Pressure Test Witnessing Independent witnessing of hydrostatic and pneumatic pressure testing on tanks, vessels, and piping to confirm integrity before commissioning.
- Civil and Structural Inspection for Plant Construction Inspection of foundation, structural steel, and civil works associated with chemical and petrochemical plant construction, verified against approved drawings and specifications.

Our Chemical and Petrochemical Inspection Process
- Step 1 — Scope and Standards Confirmation You share project drawings, technical specifications, and applicable PESO, PNGRB, or code requirements. We confirm scope and provide a cost estimate.
- Step 2 — Inspector and NDT Resource Assignment We assign inspectors and NDT technicians experienced in chemical and petrochemical plant inspection.
- Step 3 — Stage-wise Site Inspection Our inspectors carry out inspection at each fabrication and construction milestone — material receipt, welding, foundation, safety system installation, and testing — verifying conformance at every stage.
- Step 4 — Inspection and Test Reports You receive detailed reports for each milestone, including findings, NDT results, photographic evidence, and any non-conformances identified.
- Step 5 — Follow-Up and Closeout Verification Where non-conformances are found, we support corrective action verification and re-inspection before the milestone is signed off.
