Commissioning of India's Only NABL-Traceable 300-Bar Parr Oxygen Vessel Hydrotesting Facility
Orbit expands its central service engineering laboratory in Hyderabad with certified 300-bar hydrostatic proof testing and ultrasonic flaw detection.
Executive Overview
To ensure maximum operator safety across India's power and testing sectors, Orbit Technologies commissions an upgraded hydrostatic pressure proof testing center in Hyderabad for Parr oxygen bombs and high-pressure reactors.
High-pressure oxygen combustion vessels operate under intense cyclic mechanical and chemical stress. Over hundreds of firings, micro-fissures and thread wear can develop, making mandatory periodic hydrostatic proof testing an indispensable safety requirement under ASME and Parr factory safety guidelines.
Orbit Technologies has completed the commissioning of its upgraded, NABL-traceable 300-bar (4,350 psi) Hydrostatic Pressure Vessel Testing Facility at its Hyderabad headquarters. This makes Orbit the only authorized facility in South Asia equipped to perform OEM-certified proof testing and vessel recertification for Parr oxygen bombs and stirred reactors.
The testing protocol includes precision ultrasonic wall thickness profiling, microscopic thread flank inspection, 300-bar hydrostatic pressure holding with zero pressure loss verification, and comprehensive ultrasonic flaw detection. Each tested vessel receives an official Certificate of Proof Testing and safety logbook update.
This facility supports hundreds of thermal power stations, commercial coal testing agencies, and pharmaceutical chemical synthesis plants across India, preventing catastrophic vessel failures and keeping laboratory personnel safe.
Key Technical Highlights
- Authorized OEM hydrostatic proof testing up to 300 bar (4,350 psi).
- NABL-traceable digital pressure logging and ultrasonic wall thickness verification.
- Microscopic screw-thread flank and sealing shoulder wear analysis.
- Official safety recertification and issuance of Proof Test Certificates.
- Over 450 oxygen vessels and high-pressure reactors recertified annually.
