How the LPG / PNG pipeline system works
A reticulated gas system supplies uninterrupted gas from a centralized cylinder bank or bulk storage facility to every end user through a network of pipelines — reaching the kitchen, bathroom or heating appliance in each home.
Storage pressure is stepped down to safe appliance-level pressure through a series of regulators. Automatic Changeover Regulators keep supply flowing even when a service cylinder bank runs out, while Under-Pressure Shut-Off (UPSO) and Over-Pressure Shut-Off (OPSO) regulators add further safety.

3-Stage Pressure Regulation System (PRS)
Cylinder pressure is reduced in three controlled stages — from the gas bank all the way to your stove — so gas always reaches your appliance at exactly the right, safe pressure.
PRS – I
At the centralized gas bank
Installed at the gas bank, with active and standby cylinder manifolds. Each manifold is a battery of cylinders connected in parallel to a common line.
- An Automatic Changeover Regulator switches to the standby bank the moment the active bank is exhausted — no interruption.
- The OPSO valve shuts off supply if pressure exceeds safe limits.
- Advanced leak detection provides an added layer of protection.
PRS – II
At the building basement / stilt level
Feeds the header and riser pipes that carry gas up to each individual flat.
- UPSO shuts off supply if outlet pressure drops due to a leak.
- OPSO shuts off supply if outlet pressure rises unexpectedly.
PRS – III
Before each flat's gas meter
Steps pressure down to the level required by the stove connection inside every home.
- UPSO instantly cuts supply if flow is interrupted or a burner is accidentally left open during downtime.
- To restore supply, close the burner and wait 1–2 minutes — eliminating any risk of leakage.

Why choose a reticulated gas system?
Demand for LPG in India is vast and still growing — millions of households already depend on it, with many more on waiting lists and annual demand rising around 12–13%.
Yet limited domestic availability, infrastructure constraints and bottling capacity make it hard for conventional supply to keep pace with that demand.
A proven alternative
The reticulated gas system — long established across Europe and America — is the best answer. This centralized distribution network is tailor-made to each project and pipes gas safely to every user, eliminating the hassle of chasing refills. Consumers simply pay for what they use.
Why LPG reticulation
PNG supply is restricted to certain geographies and natural-gas availability isn't assured everywhere. LPG reticulated systems run on limited loops, giving tighter control and greater safety. At every stage we use state-of-the-art equipment and carbon steel pipes, tested to strict Oil Industry norms — because safety comes first, with convenience close behind.

Advantages of piped gas
A reticulated connection replaces the everyday friction of cylinders with a safer, cleaner and more convenient supply.
Continuous gas supply at the turn of a tap — no downtime.
No waiting for a replacement once a cylinder runs out.
Frees up the kitchen space previously taken by cylinders.
Built-in under/over-pressure shut-off regulators for added safety.
A cleaner, clutter-free and more aesthetic kitchen.
No money or floor space tied up in a spare cylinder.
Prepaid, AMR & AMI gas meters
Pair your piped gas supply with 9sign smart meters for tamper-proof, estimate-free billing and full visibility of consumption.
Prepaid Gas Meters
9sign prepaid gas meters are smart volumetric meters with a built-in prepayment function. Consumers top up via an IC card through the gas company's management system; the meter records the purchased volume and counts down automatically. If credit runs out or tampering is detected, the internal valve closes. Total consumed and remaining balance are shown on the LCD at the press of the Inquiry button.
AMR & AMI Gas Meters
Automated Meter Reading (AMR) and Advanced Metering Infrastructure (AMI) make utility meters smart and interactive. 9sign gas meters report consumption automatically, so you get:
- Accurate bills — no more estimates
- No one visiting to read your meter
- No manual readings to submit yourself
- Remote ON / OFF control of the meter*
Through the mobile app, consumers can see exactly how much energy they're using and what it's costing — all tracked automatically. Smart meters operate wired or wireless to communicate with utility supplier management systems.
* Remote control available where enabled by the utility.
