Corrosion of pipes occurs because metals are sometimes susceptible to chemical reactions that weaken them. Once the metal is weakened, it is prone to rust and can form cracks and holes, which is a big problem. Corrosion protection for pipes is therefore critical, not least because once corrosion begins it can quickly spread to other pipe and non-pipe surfaces. Here are the pipe corrosion protection tips you need to know.
Monitor pH and oxygen levels in water: The wrong type of water can lead to corrosion. This is because metals such as copper can weaken if the pH is too low, which can damage the pipe lining. Ideally, you want to make sure the pH of your water is as close to neutral as possible, which is why the EPA recommends a pH range of 6.5 to 8.5. Another thing is that the oxygen content and temperature of the water should not be too high as this will promote corrosion.
Protecting Your Steel Pipelines: A large part of steel pipeline corrosion protection is adding protective linings and coatings to all metal and other surfaces. Typically, this is done by adding a layer of corrosion-resistant zinc to the surface of the metal. Corrosion can have many entry points, so make sure your beams, joints, and bolts are protected too. Use a sealant to eliminate crevices where corrosive bacteria can hide.
Beware of corrosive bacteria: Chemicals and high pH are not factors that cause corrosion. Steel pipeline corrosion can also be caused by microorganisms. You can avoid this by keeping your pipes clean. Ensure that any fluid that passes through the pipes is clean by using inhibitors or biocides or by chemically treating the water and other fluids that pass through them.
Insulated Metal Pipe: Corrosion occurs when metal surfaces come into contact with the wrong material. This is why insulation is installed, to prevent the pipes from weakening. You should be especially aware of galvanic corrosion that occurs when you come into contact with the wrong type of metal.
One metal “steals” electrons from the other, creating a weakened portion that is susceptible to corrosion. By insulating the steel pipeline, you can prevent galvanic corrosion and prolong the service life of the steel pipeline. Steel pipeline corrosion is a big problem in most industries. Thankfully, these practical and helpful pipe corrosion protection tips will help you tackle this problem before it can cost you money.
