How to plan an LPG installation: a practical checklist

A plain-language checklist for planning an LPG storage and distribution installation, from demand estimate and site layout to safety distances, approvals and commissioning.

Start with the demand, not the tank

Work out how much gas the site will actually draw, at peak and on average. Peak draw decides vaporiser capacity and pipe size. Average draw and the delivery schedule decide how much storage you need. Sizing storage too small means frequent refills; sizing it too large means paying for capacity and approvals you never use.

Choose the supply mode

Cylinder banks suit small, steady loads. Bulk storage tanks with a vaporiser suit larger or continuous loads and usually lower the cost per kilogram. Some sites start with cylinders and move to bulk later, so the layout should leave room for that.

Settle the site layout early

Storage must keep set distances from buildings, boundaries, ignition sources and each other. These distances depend on tank capacity and the rules in force, so fix the location before civil work begins. Also plan tanker access, turning space and a clear emergency route.

Design the piping and safety systems

Material and pressure rating of pipes, regulators in stages, relief valves, excess-flow valves, gas detection, emergency shut-off and earthing all need to be specified together. A good design keeps the high-pressure section short and puts isolation valves where an operator can reach them quickly.

Plan the approvals

Bulk LPG storage and pressure vessels normally need approval from the explosives and safety authority, along with local fire and municipal clearances. Requirements and timelines change, so confirm the current rules for your site and capacity before you fix a schedule.

Test and commission in order

Pressure testing, leak testing, purging, functional checks of every safety device and operator training come before the first fill. Keep the test records. They are needed for approvals and for any later audit or insurance question.

Every site is different. If you want an LPG installation planned or reviewed, send us the load and the site details.
