What is the required frequency of pressure vessel inspections?
The frequency of pressure vessel inspections depends on the type
of vessel, its operating conditions, usage intensity, and
applicable statutory requirements. Regular inspections are
essential to ensure safe operation and early detection of defects
such as corrosion, cracks, or leakage.
In India, pressure vessel inspection frequency is generally
governed by the Factories Act, 1948 and relevant state factory
rules, along with industry safety practices and manufacturer
guidelines.
Typically, inspection frequency may include:
- Annual inspections for routine safety checks and compliance
- Periodic statutory inspections as required by state factory authorities
- Internal visual checks at regular operational intervals
- Hydrostatic or pressure testing at defined intervals based on vessel type and risk category
- Additional inspections after repairs, modifications, or suspected damage
High-risk vessels or those operating under severe conditions may
require more frequent inspections, while less critical
applications may follow standard annual schedules.
Uniquo helps organizations define appropriate inspection intervals
based on risk assessment, regulatory requirements, and operational
conditions. Our inspections ensure compliance, enhance safety, and
support reliable long-term operation of pressure vessels.
