Effective drainage of water is very important, especially if you live in an area that's prone to soil erosion and flooding. Therefore, whether it's for your home or commercial property, one of the ways to ensure effective drainage is using corrugated steel pipes. However, you need to be careful in your choices so that you invest in the correct type of corrugated steel pipe. For this reason, some of the things you will want to consider when buying the corrugated steel pipes include the potential loads, the surrounding environment, such as presence of roots, and the type of coatings.
Anti-corrosion coatings serve to extend the service life of your corrugated steel pipes. Therefore, here are some anti-corrosion coating options you should know about.
Polymer Anti-Corrosion Coatings
Polymer coatings can offer protection to your corrugated steel pipes for years. This coating is usually used on both the inner and outer surfaces of the corrugated steel pipes to create a barrier that will prevent both abrasion and corrosion. The coating itself is often heavy and tough to offer maximum resistance against corrosion activity by salts and acids.
In most cases, polymer coatings are used on galvanised corrugated steel pipes as they bond well with the material used for galvanisation --usually zinc-- to prevent or minimise the effects of delamination. Polymer offers the most reliable layer of protection. The coating is made from resilient plastic material that's insusceptible to acids, chemicals, and moisture.
Asphalt Anti-Corrosion Coatings
This is one of the most environmentally friendly options because it has minimal effect on the environment. Therefore, if you are concerned about both the water side and the soil side, this is the most ideal option. It is usually applied on both the exterior and interior surfaces of the corrugated steel pipes.
Zinc Anti-Corrosion Coatings
Zinc will protect your corrugated steel pipes through galvanisation, which is one of the most effective ways of protecting corrugated pipes against corrosion and abrasion. Zinc acts as the sacrificial anode used in hot water tanks. In case of a corrosion activity, the zinc will corrode instead of the steel. Since the zinc coating "sacrifices" itself in a corrosion reaction, it may not last as long as the polymer coatings. However, it is still an economical option to protect your corrugated steel pipes.
Zinc coating is ideal when your only concerns are water as well as subsequent rusting because galvanisation is your best option for protection in such situations.
