| IS 3196 (Part 2) | Bureau of Indian Standards | Welded low-carbon steel gas cylinders for liquefiable gases (RG Series) | 100% Water-jacket testing up to 70 kgf/cm² & pneumatic leak test |
| IS 6240 & IS 15914 | Bureau of Indian Standards / JSW | Raw steel chemistry, deep drawing tensile limits, & micro-alloying specs | 100% Mill Test Report (MTR) verification & spectrometer lab pass |
| IS 3224 | Bureau of Indian Standards / PESO | Valve fittings, threads, fusible plugs (100°C melt), & safety relief devices | 100% Pneumatic submerged bubble leak testing at 12–40 kgf/cm² |
PESO Factory Licensing & Third-Party Inspection
The Chief Controller of Explosives (CCOE) / PESO licenses the BTPS Belagavi works (Plot Nos. 138-B, 140–143, Machhe Industrial Estate) for high-pressure gas cylinder fabrication.
Statutory inspectors conduct periodic plant audits, verify calibration records of our 100% water-jacket test rigs, and sign off on batch inspection certificates before any shipment leaves the plant.
PESO Compliance Pillars
- Plant Safety Authorization: Validated for high-pressure DA (16 kgf/cm² working) and RG vessels.
- Rig Calibration Audit: Pressure transducers calibrated against certified national NABL master gauges.
- 100% Burst Record Archiving: Destructive burst logs preserved for statutory regulatory review.
- Zero Product Failure Record: Supported by the World Standards Day 2025 BIS Award of Excellence.

How are BIS licenses maintained?
How are BIS licenses maintained?
BTPS maintains continuous compliance through mandatory bi-annual independent audits and continuous in-house laboratory testing. All IS specifications (IS 7312, IS 3196 Part 2) are strictly adhered to.
What is the PESO batch inspection protocol?
What is the PESO batch inspection protocol?
Every production batch undergoes inspection by an independent PESO-approved third-party agency prior to dispatch. Hydrostatic and burst tests are documented per batch.
What documentation is provided to buyers?
What documentation is provided to buyers?
Each shipment is accompanied by original manufacturer test certificates, relevant BIS conformity declarations, and specific batch inspection reports required for end-user compliance.
