Features and Advantages of Underground Gas Pipe Laying

 In Blog

Gas transportation is the pumping of natural or town gas from its point of generation to a delivery point and helps in minimise energy loss that occurs when gas is transported. The requirements for installing gas pipelines somewhat differ based on various factors, such as the presence of utilities, terrain conditions and soil composition.

What are the two common methods?

Underground gas pipe laying is done in two ways:

1. Excavation Method

The trench is dug up with the help of heavy machinery such as excavators, bulldozers and other machines. The trench is then manually excavated using hand tools like shovels and spades to minimise damages to existing utilities and services.

After digging up the trench, the pipes are laid in it using specialised equipment. Once laid, the trench are backfilled with quarry dust and earth and compacted by using vibratory compactors to make sure there are no movements while operating at high pressure.

2. Tunnelling Method

For this method, an open trench is not required to be dug up because tunnel boring machines are used instead. The machines can bore through soft soil as well as hard rock without creating any disturbance to a landscape or surroundings

The process

Underground gas pipe laying process involves the following steps:

  1. Excavating a trench
  2. Preparation works of trench
  3. Laying of pipes into the trench
  4. Backfilling
  5. Reinstatement

Advantages of the underground gas pipe laying

Underground gas pipe laying is an essential and below are some of the benefits:

1. Minimal disruptions to traffic and the environment
Underground pipelines do not interfere with traffic because there are no above-the-ground structures such as poles or towers for them to interfere with traffic control signals or signs. Plus, it protects the environment by not disturbing the surface of the land. In a rural area, the method can be used to save crops and grass. The only thing that will be visible is a small ditch on top of the ground where the underground pipeline passes through which can be easily rectified.

2. Prevents pollution
Another advantage of underground gas pipe laying is that it prevents pollution as well as resources as it does not require much construction material or manpower. The procedure also helps in saving energy and resources when compared to other methods such as above-ground piping, because there are fewer chances of leaks or breakage. This further reduces waste generation as well as pollution levels caused by the other methods.

3. Cost Effective
Roads and landscape are build over it minimising the chances of accidents or damage to vehicles while travelling on the road. However, an alternative route or method may be required if there are no other options available.

4. Less maintenance required
Another advantage associated with underground gas pipe laying is that less maintenance is required over time because regular maintenance or repairs is not needed. In the case of above-ground piping systems, regular maintenance and repairs are necessary as they are exposed to various weather conditions such as harsh rain and winds.

Make the right choice with Lih Ming

Pipeline laying for gas transport is important for the energy security of a region. In case of an emergency, it is possible to quickly provide consumers with gas from nearby or faraway places.

Laying pipelines underground along transport routes makes it very convenient. Anyone who is responsible for the job not only considers the pros and cons of building new pipelines but also evaluates all the risks in advance and takes preventive measures.
