This case study covers a HAZOP (Hazard and Operability) study at an LPG cylinder manufacturing plant in Hyderabad — the same facility covered by a QRA case study in this project’s immediately preceding batch, completing the HAZOP/QRA pair for this site, consistent with the sequential relationship established across this project’s other paired process safety content. As explained in that companion QRA case study, cylinder manufacturing carries a hazard profile distinct from LPG bottling (filling operations covered elsewhere in this project): rather than pressurised-gas-transfer risk, this facility’s hazards center on pressure testing (each cylinder tested to well above rated working pressure before certification) and welding process quality (a defect that passes visual inspection but fails under pressure). This HAZOP study systematically worked through the forming, welding, and pressure-testing stages using guide-word review, identifying the specific deviation scenarios — welding defect propagation, over-pressurisation during testing, and test equipment failure — that then fed into the numerical risk calculation covered in the companion QRA case study. NCRB recorded 7,566 fire accidents in India in 2022, and while cylinder manufacturing’s hazard profile differs from gas-handling facilities, pressure vessel failure during testing and latent welding defects remain serious, checkable hazard categories this HAZOP study specifically addressed through structured design review. A HAZOP study for a cylinder manufacturing plant of this scale typically costs ₹6–14 lakh. This case study covers what the study identified across forming, welding, and pressure-testing stages, and how those findings connect to the companion QRA study’s numerical risk calculation.
This HAZOP study completes the pair for the Hyderabad LPG cylinder manufacturing plant covered by QRA in this project’s immediately preceding batch — identifying welding defect and pressure-testing deviation scenarios that fed into that QRA’s numerical risk calculation.

FAQs
Q1: How much does this HAZOP study cost?
The cost of a HAZOP study for an LPG cylinder manufacturing plant depends on the number and complexity of manufacturing stages, process equipment, P&IDs and other design documents, HAZOP nodes, workshop duration, multidisciplinary team requirements, and reporting scope. Elion has documented a HAZOP assessment specifically for an LPG cylinder manufacturing plant in Hyderabad, but the published case study does not state the actual project fee.
Q2: How does this relate to Elion’s QRA at the same facility?
The HAZOP and QRA are complementary assessments at the Hyderabad LPG cylinder manufacturing facility. HAZOP systematically examines process deviations, their causes, consequences, and safeguards. The QRA goes further by identifying hazards, analysing consequences, estimating risk, and supporting risk-mitigation decisions. Elion separately documented a QRA at the same type of LPG cylinder manufacturing facility in Hyderabad, with fire, explosion, and toxic-gas-release risks among the assessed hazards.
Q3: What deviation scenarios were identified?
The published HAZOP case study does not provide a complete node-by-node deviation register, so specific deviations should not be invented. Based on the documented scope, the assessment addressed hazards associated with the manufacturing process, handling and storage of flammable gases, production equipment, and operational conditions. The exact guideword deviations, causes, consequences, and safeguards should be taken from the detailed HAZOP worksheets/report.
Q4: How does this compare to Elion’s LPG bottling plant HAZOP content?
The underlying HAZOP methodology is similar, but the process hazard profile is different.
An LPG bottling plant primarily involves receiving, storing, transferring, filling, and dispatching LPG, so its HAZOP focuses heavily on storage tanks, transfer systems, bottling operations, pressure management, and LPG containment. Elion’s LPG bottling HAZOP content, for example, identifies storage-tank overpressure and pressure-relief-system maintenance as important issues.
The cylinder manufacturing HAZOP instead needs to address the manufacturing and testing process itself, including forming, welding, pressure testing, equipment operation, and any associated flammable-gas handling. Therefore, the same generic HAZOP guidewords may be used, but the nodes and deviations must be tailored to the manufacturing process.
Q5: Why does cylinder manufacturing need its own HAZOP scope?
Cylinder manufacturing cannot simply be treated as an LPG bottling operation because the processes, equipment, hazards, and design intent are different. Manufacturing involves activities such as forming, welding, testing, and quality-control operations, while bottling involves handling and filling LPG into finished cylinders.
A dedicated HAZOP scope ensures that hazards specific to manufacturing equipment and process stages are systematically examined rather than being overlooked by using a bottling-plant checklist. Elion’s Hyderabad case study specifically describes the cylinder manufacturing facility as having its own production processes and inherent manufacturing-related risks.
