Polyethylene gas pipes have many excellent qualities that make them suitable for use in the gas and mining industry. They are used for making gas pipelines PE for collection and distribution of gas and water at high pressure. http://www.reaygroup.com.au

1. Why Gas Pipelines PE Are Widely Used
PE pipes are widely used in the gas mining sector to make gas and water pipelines. They are
extensively used in various areas of this sector including the gathering and distribution of
natural gas to other areas. These pipes are ideal for such applications due to some of the
qualities they possess. To begin with, polyethylene has a high long term pressure rating. This
means that it can be used for a long time under sustained high pressure without any problems
arising. This is one reason why they are ideal for high pressure gas and water pipes as they will
last longer.
Water and gas at high pressure can produce powerful surges that can be felt within the pipes
they are passing through especially if the pipes are made of rigid materials like metal or
concrete cylinder. With the polyethylene gas pipe, these surges are minimal. This is due to the
inherent flexibility of polyethylene pipes that enables them to dampen and absorb the shock
waves easily. This means that there will be less damage to the entire piping system because the
destructive effects of the surge are minimised.
The PE gas pipelines are manufactured in varied coil lengths and can be easily joined together
through mechanical means or using heat fusion method. They are light in weight and are easy
to install without the need for too much time or labour. One big advantage that they have over
metallic pipes is that they don’t corrode. The PE pipes therefore cannot contaminate the water
passing through them like the metal pipes do after some time.
The standard poly pipe is strong enough to resist any forces that usually cause inward collapse
or buckling when used for underground piping. Buckling is very common in underground pipes
whenever the total load acting on them is more than the critical buckling resistance of the
pipes. To help improve the PE pipe’s resistance to buckling, they can be strengthened more by
putting solid lateral soil support in the trenches where the poly pipes are buried.
Polyethylene pipes are much cheaper than the other types of pipes and this also contributes to
their widespread use in the gas and mining industry. You get to save money on the actual
purchase and on installation work. Polyethylene pipes are also suitable for use above the
ground as they are also resistant to the sun. In addition, they are inert and have low friction
therefore materials can flow through them smoothly.
