5 Major Factors Influencing Pipe Deterioration
Along with operational and physical factors that influence pipe deterioration, there are a few environmental factors that also play a role in weakening and breaking down of a sewer pipe. Pipe deterioration if not solely based on age and defects in the assemblage, improper installation and factors in the environment also play a great part to contribute to breakage, cracks and other problems. Here is a short list of factors a homeowner needs to watch out for preventing pipe deterioration:
- Pipe Bedding
During pipe the installation process, the structural performance of a pipe is predicted and affected by the structural design analysis done by the plumber. When a pipe is having problems even on its earlier duration period and continue to experience such, the fault may lie in the manner in which the pipe was laid on the ground. Improper bedding of the pipe will affect its structural performance and durability and will somehow cause the early pipe failure and lack of structural result.
- Trench Backfill
When installing a pipeline or sewer line, some areas may need excavation. Some of the excavation areas may be huge while others are needed to be considerably small. After the excavation process, backfill that goes above the pipe may be corrosive and harmful to the materials composing the pipe. Careful backfilling is needed to avoid failures in the piping. Remember that backfills should be free from corrosive chemicals, substances and materials that can possibly be threatening the health of the pipes.
- Soil Type
Sewers are buried below the ground which means that they tend to have constant contact with soil around them. The soil has different kinds. They have different characteristics and possess different chemicals in them. Some may contain chemicals or substances that may be corrosive to the pipe. There are soil types that experience changes in volume when they get exposed to humidity and moisture. As this happens, the dead load on top of the pipe increases, therefore, increasing the stress on the pipe.
Hydrocarbons and soil solvents are present in some soil types and this result in deterioration of the pipe embedded. As a precautionary measure, before burying pipes in your property, ensure the security of your pipes.
- Groundwater and Its Level
As groundwater level rises, the possibility of the soil below the sewer being washed away is high. When put in direct contact with the pipe, they can be the cause of pipe deterioration. This is made a high probability when the chemicals and pollutants present in the water are aggressive to the materials that make up the pipe.
When the soil around the sewer gets washed away by the groundwater, the pipes are left hanging without support. During this period, the pipes become unstable causing them to have poor structural performance and lesser durability caused by the stress, unsteadiness and instability.
- Pipe Location
In winter, ice and frost litter the area. The solution that homeowners find to deice the area is to scatter salt above it. The salt will result in the weakening of the structure of the pipe as it reaches to penetrate the ground. They are the main reasons for corrosion, especially for metal pipes.
