Industrial LPG Gas Pipeline Installation Services: Complete Guide
Industrial LPG gas pipeline installation services are fundamentally different from commercial kitchen gas work. You are no longer dealing with a 5-10 kg/hr kitchen demand — you are sizing a system that can deliver 50-500 kg/hr continuously to boilers, thermic fluid heaters, ceramic kilns, metal-treatment furnaces or process ovens. The engineering, the compliance regime, and the failure consequences are all larger.
Sahil LPG Services has delivered industrial gas pipeline installations for food processing plants, metal treatment shops, ceramics factories, textile dyeing units, pharmaceutical plants, and auto-component manufacturers. This guide covers the core decisions every industrial buyer faces.
Storage sizing: bulk tanks vs cylinder manifolds
The first major decision is storage form factor. Practical guidance:
- Cylinder manifolds (16-32 cylinders): demand below 100 kg/day, typically small workshops. Low capex but high cylinder-handling labour.
- Mini-bulk tanks (450-990 kg): demand 100-500 kg/day. Single delivery truck fills the tank; no daily cylinder handling.
- Bulk bullet tanks (1-25 MT): demand 500 kg to 5 MT/day. Economical per-kg cost, weekly/monthly refills.
- Mounded bullets (10-100 MT): demand above 5 MT/day. Urban sites with space constraints or enhanced blast protection needs.
Larger storage brings per-kg cost savings (typically 15-25% lower than cylinder rates) but higher capex and mandatory PESO compliance.
Vaporiser selection
Industrial demand above about 100 kg/hr continuous cannot be met by natural cylinder vaporisation — the liquid doesn't boil off fast enough. You need a vaporiser. Two main types:
- Electric direct-fired: compact, cheaper (₹1.5-3 lakh for 50-100 kg/hr). Direct electric heat to the liquid. Requires careful thermostat control.
- Electric indirect / waterbath: safer, longer-life (₹3-8 lakh for 100-300 kg/hr). Electric element heats water; water heats the LPG. Preferred for industrial continuous duty.
- Steam-heated: for plants with existing steam infrastructure. Zero additional electrical load.
- Hot-water circulation: waste heat from process → warmed circulating water → vaporiser. Maximum efficiency.
Medium-pressure backbone design
Industrial plants usually have multiple consumption points spread across the factory floor. The most efficient distribution is a medium-pressure backbone running at 1-5 bar, with individual PRS (pressure reducing stations) dropping to low pressure at each burner.
Medium-pressure distribution means smaller pipe diameters (lower capex) and lower pressure losses across long runs — critical in plants where the vaporiser may be 100-500 m from the furnace.
OISD compliance: what the regulator expects
Industrial LPG storage and distribution fall under OISD (Oil Industry Safety Directorate) guidelines, primarily:
- OISD-144: Liquefied Petroleum Gas (LPG) storage and handling. Covers tank spacing, bunding, fire-water requirements.
- OISD-194: Storage and handling of LPG in bulk — distances, safety zones, vent sizing.
- IS 6044: Code of practice for LPG installations.
- IS 15330: Code for gas distribution systems.
Our designs are pre-aligned with these standards, which reduces approval turnaround significantly.
Emergency Shutdown (ESD) systems
Industrial LPG installations require ESD systems that automatically stop flow on:
- Gas detection in the storage area
- Heat / flame detection
- Manual pushbutton activation
- High-pressure trip at the distribution header
- Low-pressure trip (could indicate downstream rupture)
ESD valves (ESDVs) are fail-safe — they close when the signal is lost. Integration with plant DCS is standard for tier-1 manufacturers.
Custody transfer flow metering
Plants allocating gas cost across departments (thermal utility, process heating, canteen) benefit from flow metering at each consumption point. Ultrasonic and turbine meters are standard; both give 1-2% accuracy at low running cost.
Capex benchmarks
Indicative 2026 capex for turnkey industrial LPG installations:
- Small workshop (16×16 manifold, MS distribution, 2-3 points): ₹3,50,000 – ₹8,00,000
- Medium plant (1-2 MT bullet, 50 kg/hr vaporiser, 4-8 points, ESD): ₹18,00,000 – ₹40,00,000
- Large plant (10 MT bullet, 200 kg/hr vaporiser, DCS integration, custody metering): ₹60,00,000 – ₹1,50,00,000
- Greenfield mega-site (50+ MT mounded, LOT, multi-vaporiser, DCS): ₹2,00,00,000 – ₹5,00,00,000
Frequently asked questions
Do you handle PESO licensing for bulk storage?
Yes — we prepare the full PESO application, all supporting drawings and calculations, and liaise with the authority through approval. Licensing typically takes 8-16 weeks.
Can you retrofit our existing plant?
Yes — we specialise in brownfield retrofits with minimal production disruption. Work is planned around plant shutdowns or maintenance weekends.
What about LOT vs VOT for industrial plants?
LOT (Liquid Off Take) is preferred above 100 kg/hr sustained demand. VOT (Vapor Off Take) is cheaper but limited to moderate loads. See our detailed LOT vs VOT comparison.
