What Causes Pipe Corrosion?

There are a few factors that increase the risk of pipe corrosion. High water temperature increases the oxidation rate, making hot water lines more prone to corrosion. Closed loop piping systems, which circulate and pump water, are also at risk. Water turbulence creates erosion corrosion at locations where the flow of water is slowed or diverted abruptly. Excessive velocity, sudden changes in direction, and flow obstacles can also cause turbulence.

Galvanic corrosion

A simple definition of galvanic corrosion is the process by which two metals that are not compatible with each other come into contact with a water solution. The contact must be good enough to conduct electricity and both metals must be exposed to the water. The difference in potential between the metals is the driving force of galvanic corrosion, which is accelerated by distance. Luckily, galvanic corrosion can be prevented by using dielectric fittings. However, they can’t stop the corrosion of thin-walled pipes.

Metals with different electrochemical potentials will cause corrosion in one another. The higher the potential, the stronger the reaction. A list of metals that are resistant to galvanic corrosion can be found below. Stainless steel is the most common type of stainless steel, and is often used in industrial settings because of its high molybdenum content. It also resists scaling at high temperatures and is used in marine applications. Basic ferritic steel is less resistant to galvanic corrosion but is usually too expensive to be used in a distribution system. Cnadu Plumbers in CA are providing the best piping services.

Water chemistry

There are several factors that contribute to pipe corrosion. Firstly, the chemistry of water should be balanced. If the concentration of alkalinity is greater than the amount of other ions, the risk of corrosion increases. In addition, it is essential that the pH level should be between 7.0 and 7.4. If the PH level is lower than that, the corrosive effect of calcium carbonate increases. To determine the optimum water chemistry, you must test your pipes.

The higher the water temperature, the higher the oxidation rate. Therefore, hot water lines are prone to corrosion. Another issue is water velocity. Closed loop piping systems, such as hot water lines, require circulating or pumping water. Water turbulence, which occurs at areas of high velocity, sudden changes in direction, or obstacles in the flow, promotes corrosion. Therefore, it is essential to monitor the chemistry of water in your pipes to prevent premature corrosion.

Protective coatings

Pipes that are insulated may not be protected from corrosion. In these cases, protective coatings may not prevent water from becoming trapped in the pipe’s crevices, accelerating corrosion beneath. Protective coatings fail to resist the effects of corrosion over time, particularly when the pipe moves. In some cases, the protective coating may be improperly applied. Here are three reasons why insulating your pipes is important.

One of the most obvious causes of pipeline failures is inadequate protective coatings. One example of this is the May 2015 oil spill near Santa Barbara. The Pipeline and Hazardous Materials Safety Administration (PHMSA) concluded that the spill was caused by external corrosion. This corrosion caused the pipe to thin to the point that it ruptured suddenly. The pipeline’s condition contributed to the external corrosion. The coatings were not properly protected against ultraviolet rays, which can damage pipelines.

Water softener

When water is extremely hard, it leaves a mineral buildup inside your pipes. Copper and steel pipes are especially susceptible to this buildup, which reduces the inside diameter and limits water flow volume. It also wears away at plumbing fixtures and causes them to leak. A water softener helps to eliminate mineral buildup in your plumbing, which can prevent costly repairs and replacements. Here’s why a water softener is important.

Hard water contains a large amount of sodium, which is particularly corrosive. While a water softener removes the sodium and calcium from water, it leaves minerals such as potassium in the water, which can cause corrosion. These minerals cause more damage to your plumbing than calcium and can take years to fix. That’s why WQA recommends against installing metal pipes downstream from RO or DI treatment systems. Water softeners can also result in increased copper and lead levels. Water softeners should be installed only after a thorough investigation of the problem.
