We are very fortunate of having access to gas, be it natural or propane. Various options are depending on geographical locations.  The demand for gas for your home or industrial usage also impacts on the type of the regulator, meter, cylinders or bottles and size of pipes installed. Since 2010 many of the suburbs within a 15-kilometre radius of CBD got the access to upgraded gas pipelines in the street. Similar projects are still being rolled out today in various suburbs, which have outdated steel low-pressure natural gas lines and needs for frequent Gas Line repair in Adelaide.

Reason for upgrading the pipelines is that the old steel and cast-iron pipes develop leaks over an extended period and pressure of demand placed on the supply has also increased with the ever growing population. New pipes, which are now being installed, are polyethene products commonly known as Tiger Pipe. The reason for such a pet name that is used for Gas Line repair in Adelaide is due to the black colour of the pipe itself with yellow stripes.  Another reason for selecting these pipes upgrading the pipelines across the state is that it can be placed into the existing cast iron pipes and installed instead of the entire pipe line being excavated.

Whenever the pipe reaches a branch or tee piece, a localized hole in the ground is made to enable this connection. In most of the upgrades, Gas Line repair in Adelaide can be performed with minimal disruptions on the surface.  After the new branch is made on the ground, there will be a re-bituminized road or a fresh layer of paved over.

The flow of natural gas depends upon the pipeline to work at its optimized level.  With the new tiger pipeline installed, the internal diameter of the pipeline has been deliberately reduced so that it can fit inside the old steel pipes underground. For overcoming the problem of reduced flow, the pressure inside of the new gas lines has been increased. You can now see that the infrastructure properties of the street have been upgraded and needs a high-pressure regulator installed at the gas meter on the incoming leg after the isolation valve. This is the reason for installing high-pressure regulator for receiving gas inside the boundary lines of consumer & its appliances should be rated to withstand a maximum static pressure of 3.5 kph.

When the gas is turned off at homes & properties are enabled for new lines to be connected as a test for soundness that needs to be performed on the consumer pipeline before the gas can be reinstated in the property.  Unfortunately, many pipelines have developed leaks over the years of being underground. If a leak is found out the consumer’s gas cannot be reinstated until the leak is fixed.

What should we do in a Gas Leak?

As soon as there is a suspected gas leak reported to our office, there are few points, which we discuss with our clients before initiating the gas line repair in Adelaide. Accordingly, we plan to work and complete the property.

 Our service technicians attend the issue at the property and confirm that there is an actual leak. We isolate all the attached appliances from the consumer pipeline and retest the services to confirm if the leak persists.

If the leak still exists, we proceed to test the exposed sections of the pipeline for leaks at the joints & other mechanical connections.

After this issue is resolved, we try to separate the underground pipeline from the above-ground sections of the gas lines & try to identify the leaking section. Majority of leaking cases is in the underground pipeline which is due to the erosion of underground cast iron pipes for over 50 years.

Once the gas leak has been narrowed down, the plan for replacing the pipeline will be executed. Today the majority of pipelines from the main meter to the building are commonly installed in the copper tube. The length of the pipe from the gas meter to the building is approximately 20 meters for the majority of domestic properties in Australia.  The size of the copper pipes and fittings are used for new gas mains, from the meter to the building which ranges from 25mm (1inch) to 50mm (2inch), there are more fixtures on the property that dictates a larger pipe size, i.e. 50mm. 

Repairing Methods

Our preferred method for joining new and existing copper pipes is of using a process known as pressing.  Technological advances have already moved ahead by leaps and bounds in the plumbing industry. We are adopting this process which makes us the market leader in the plumbing sector and offers big benefits to our clients.  We are reducing the chance of leak during the installation processes and more often minimizing the Cost of gas fitter required to install the pipeline.  Today there are more than five manufacturers who produce this type of copper and brass product, ranging from 15mm all the way up to 100mm but the more common brand and the first one to introduce the product to the Adelaide market was a German company named Viega.  Once you have purchased the necessary tools for assembling the fittings, it becomes a very simple process and about 100% guaranteed not to leak again if installed as per the manufacturer’s specifications.
