Corrosion in steel pipes occurs because metals are sometimes susceptible to chemical reactions that weaken them. Once the metal is weakened, it becomes susceptible to rust and can form cracks and holes, which is a big problem. Therefore, it is vital that steel pipes are protected against corrosion, especially because once corrosion begins, it can quickly spread to other steel pipes and non-steel pipe surfaces. Here are the tips you need to know to prevent corrosion on steel pipes.
1. Monitor pH and oxygen levels in water
The wrong type of water can cause corrosion. This is because if the pH is too low, metals such as copper can weaken and damage steel pipe linings. 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.
2. Protect your steel pipes
A large part of protecting steel pipes from corrosion 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 metal surface. Corrosion can have many entry points, so make sure your beams, joints and bolts are protected too. Use sealants to eliminate gaps where corrosive bacteria can hide.
3. Beware of corrosive bacteria
Chemicals and high pH are not factors that cause corrosion. Steel pipe corrosion can also be caused by microorganisms. You can avoid this by keeping your steel pipes clean. Make sure any fluids passing through steel pipes are clean by treating water and other fluids passing through them with inhibitors or biocides or chemicals.
4. Insulated metal pipes
Corrosion occurs when a metal surface comes into contact with the wrong material. This is why insulation is installed to prevent steel pipes from weakening. You should pay special attention to galvanic corrosion that occurs when you come into contact with the wrong type of metal. One metal "steals" electrons from another, creating a weakened portion that is susceptible to corrosion. By insulating steel pipes, you can prevent galvanic corrosion and extend the life of steel pipes. Steel pipe corrosion is a big problem in most industries. Thankfully, these practical and useful steel pipe corrosion prevention tips will help you solve this problem and avoid huge losses.
