Industrial Gas Installers
Cape Town

Industrial LPG installations differ from commercial ones in scale and in consequence. The loads are larger, the pipe runs cross whole sites, and an unplanned gas outage does not just spoil a service — it stops a production line, scraps work in progress and puts a shift's output at risk.

Below: how large systems are sized, what changes when draw is continuous rather than intermittent, and how an industrial gas installation gets built on a site that has to keep running.

Facilities This Applies To

• Manufacturing plants using gas for process heat, drying, curing or finishing
• Food production facilities running continuous cooking, frying, baking or blanching lines
• Warehouses and distribution centres with LPG forklift fleets and cylinder exchange points
• Workshops and fabrication shops using gas for heating, cutting or forming
• Industrial and central production kitchens operating at a scale well beyond a restaurant line
• Laundries and commercial cleaning operations with gas-fired dryers and irons
• Large commercial properties such as hospitals, campuses, hotels and shopping centres with central plant

Industrial Applications for LPG

LPG turns up in more places on an industrial site than most people expect:

• Process heat — burners, furnaces, kilns and heat treatment
• Steam raising — gas-fired boilers serving process or space heating
• Drying and curing — paint and powder coating ovens, timber and agricultural drying, print curing
• Direct-fired space heating in high-bay warehouses and workshops
• Forklift fleets — cylinder exchange stations and refill points, plus safe storage of full and empty cylinders
• Shrink wrapping, flame treatment and singeing on packaging and textile lines
• Standby and dual-fuel arrangements where LPG backs up another energy source

Each application has a different demand profile, and the profile matters more than the headline number when the system is sized.

Sizing an Industrial LPG System

The method is the same as a commercial kitchen but the answers land in a different place, and three factors dominate:

1. 1Peak draw. The maximum flow the system must deliver at once. This sets pipe diameter, regulator capacity and vaporisation requirement.
2. 2Duty cycle. Industrial demand is often continuous for a full shift rather than spiking for two hours. Sustained draw is much harder on storage than intermittent draw of the same magnitude.
3. 3Consumption between deliveries. Total volume used per week or per shift, which sets storage capacity and delivery frequency.

Diversity, which allows a commercial kitchen to be sized well below its connected load, is usually much less generous on an industrial site. Process equipment tends to run when the line runs, and if the line runs continuously so does the demand.

Vaporisers and High-Draw Installations

Cylinders and tanks vaporise liquid LPG using heat drawn from the surrounding air, and there is a limit to how fast that happens. Once industrial draw exceeds what natural vaporisation can supply, pressure falls and the vessel chills regardless of how much liquid is inside.

There are three ways round it:

• More vessel surface area — a larger tank or more cylinders in the bank, which increases the wetted area available for vaporisation.
• A vaporiser — a unit that draws liquid from the vessel and applies controlled heat to vaporise it, decoupling gas output from ambient conditions entirely. This is the standard answer for high, sustained industrial draw.
• Liquid offtake with downstream vaporisation for very large installations.

Vaporiser installations bring their own requirements around siting, electrical supply, controls and protection, and they should be designed in from the start rather than added later when the pressure problem appears.

Site Layout, Separation and Access

On an industrial site the storage position has to satisfy several competing demands at once:

• Separation from the buildings it serves, from boundaries, and from ignition sources, with distances that increase with the size of the installation
• A firm, level, non-combustible base, with the surrounding ground graded so leaked gas does not run toward pits, trenches, basements or drains
• Vehicle access for a delivery tanker, including turning space and standing position
• Protection from site traffic, forklifts and reversing vehicles, usually with bollards or barriers
• Separation from stored combustible materials, waste and stock
• Isolation points that emergency services can reach without entering the hazard area
• Signage, and exclusion of electrical equipment from the immediate zone unless it is suitably rated

Getting this settled early matters, because storage position affects the pipe route, the pipe route affects the cost, and both are difficult to change once the concrete is poured.

Pipework Across an Industrial Site

Industrial pipe runs are longer and more exposed than commercial ones, which changes what the design has to account for:

• Larger diameters, usually steel, carried on purpose-built supports
• Corrosion protection on external runs — particularly on Cape Town's coastal industrial sites
• Expansion allowance on long runs exposed to daily temperature swings
• Buried sections in polyethylene where the run crosses yards or roadways
• Impact protection wherever plant and vehicles operate
• Sectional isolation so one production area can be shut down without stopping the whole site
• Test points along the run so faults can be narrowed down quickly during a breakdown
• Clear labelling and up-to-date as-built drawings held on site

Sectional isolation deserves particular attention. On a site where several areas share one supply, being able to isolate a single line for maintenance without shutting down production elsewhere pays for itself the first time it is needed. Pipe sizing and materials are covered further on the commercial gas pipeline installers Cape Town page.

Installing Around Production

Very few industrial sites can stop for a gas installation. The work is normally sequenced so the shutdown window is as short as possible:

• Storage compound, base and vessel installed entirely off the live system
• New pipework routed and pressure tested while the existing supply continues to run
• Tie-in scheduled into a planned maintenance window, a shift changeover or a shutdown period
• Commissioning done equipment by equipment so the line can be brought back progressively
• Contingency planned for the tie-in, because that is the step with no easy way back

Site inductions, permits to work, hot work permits and contractor access arrangements all add lead time on industrial sites, and they are worth confirming during quoting rather than on the first morning.

Compliance and Documentation

Industrial gas installations generate more paperwork than commercial ones, and the documentation is worth insisting on:

• Certification of the installation on completion by an authorised person
• As-built drawings showing pipe routes, diameters, isolation points and test points
• Load calculations and the design basis for the system as installed
• Test records from strength testing, tightness testing and commissioning
• Equipment documentation for regulators, vaporisers and safety devices
• A record of isolation points and emergency shut-off locations for site safety files

This documentation is what makes the next alteration straightforward instead of an investigation. It also tends to be what an insurer, an auditor or an incoming facilities manager asks for first.

Industrial Gas Installation Costs in Cape Town

For an accurate quote, the most useful inputs are a schedule of gas-consuming equipment with rated inputs, an indication of how many hours a day each runs, a site plan, and your available shutdown windows.
