How Different Sewer Lines Are Affected By Corrosion
Corrosion can cause leaks, breaks, blockages, and contamination of the wastewater system. It can also reduce the lifespan of the pipes and increase maintenance and repair costs. In sewer lines, corrosion can be caused by various factors, such as the chemical composition of wastewater and the presence of dissolved oxygen. Different types of sewer lines are affected in different ways.
How Corrosion Affects Different Types of Sewer Pipes
Sewer pipes can be made of different materials, such as cast iron, ductile iron, steel, concrete, clay, or plastic. Each material has its own advantages and disadvantages in terms of corrosion resistance, durability, cost, and performance.
Cast Iron Pipes
They are strong, rigid, and resistant to abrasion. However, they are also prone to corrosion, especially uniform attack and pitting.
Ductile Iron Pipes
They are more resistant to cracking and breaking than cast iron pipes. However, they are still susceptible to corrosion, especially galvanic corrosion and erosion.
They are easy to install and repair. However, they are very vulnerable to corrosion, especially uniform attack and galvanic corrosion.
They are less likely to leak than metal pipes because they have fewer joints. However, they are not immune to corrosion, especially from sulfuric acid produced by bacteria in wastewater.
They are durable and have a long lifespan. However, they are brittle and prone to cracking from external forces or temperature changes.
They are easy to install and repair. However, they are not suitable for high temperatures or pressures.
If you have corroded metal sewer lines that leak or cause problems in your wastewater system, you need to call a professional sewer line repair service as soon as possible. They can inspect your sewer lines using video cameras or other tools to determine the extent and location of the corrosion damage.
This is a trenchless method that involves inserting a resin-coated tube into the damaged pipe and inflating it to form a new pipe within the old one. This can seal the leaks and restore the pipe's function and capacity.
This is another trenchless method that involves pulling a new pipe through the old one using a hydraulic device. The old pipe is fractured and pushed aside by the new pipe. This can replace the corroded metal sewer line with a new one that is stronger and more durable.
This can be done using open-cut or trenchless techniques, depending on the site conditions and accessibility.
