Material selection is the primary measure for corrosion control, but the importance of better design cannot be stressed upon enough. A better design that takes into consideration everything. The curses of corrosion can significantly increase the chances of a metallic design against rust.
To avoid corrosion, there are quite a few considerations that the designers of metallic architectures and showpieces need to make. Some important considerations that a designer must follow for corrosion control are as follows:
Moisture is the major cause of the corrosion, right? It is necessary, therefore, for storage containers—such as tanks—to be designed in such a way that ensures for them to be easily and drained and cleaned. For that to happen, their designers will need to ensure that the taps are placed to receive every last ounce of the liquid out of the tank, so that it may be cleaned. Designers need to ensure that there are smooth transitions and design in accordance with the placement area of the tank.
Minimizing Temperature Gradient
The designers of the equipment of heat transport need to ensure, for the purpose of corrosion control, that cold and hot spots are not formed on the surfaces of the materials. The equipment needs to be designed to make sure that there is little to no variation in the temperature of the surface. Temperature variations cause for the formation of hot and cold spots, both of which are susceptible to corrosion. For instance, hot spots face the threat of thermo-galvanic corrosion, whereas cold spots cause condensation which, as we all know, results in moisture that leads to corrosion if not taken care of.
Adjusting the Thickness of the Walls
For corrosion control, designers are advised to make adjustments to the thickness of the walls. What I mean by that is that corrosion continuously eats up metal and decreases its thickness. Therefore, walls which are twice as thick can be designed.
It is a common corrosion control method that designers employ, but the fact of the matter is that such a strategy isn’t always feasible. This is because the thickness of the walls of any design must meet the mechanical requirements for weight, stress and pressure.
Another reason why this method is uncommon is due to the fact that it serves for a steep increase in the cost of the architecture. Is such an increase always justifiable? No, it’s not. Thus, it is essential to conduct a cost-benefit analysis to understand whether the utility generated by the increased cost will be worth it or not.
Designers advise that their customers coat their metallic architectures with WD-40, occasionally, to ensure that they will help reduce corrosion.
No, we’re not talking dentistry here; minimizing cavities is important in architecture also. Designs with small cavities and crevices accumulate moisture, owing to the fact that air cannot circulate freely through these crevices. What this means is that you do not spend enough time cleaning up these crevices and they can quickly turn a shade of yellow. Designers should try to limit such cavities and crevices in their architectures, as much as possible.
The use of WD-40 should be recommended to all customers, for corrosion control, so that they do not have to suffer from the problem that has already been discussed.
Designers will need to remember the fact that their designs will exist in an open environment and will be openly interacting with the elements. Considering the environment of where their designs are key. If a metallic showpiece is to be bought by an individual who resides near the seaside, then it is imperative for the designer to use such materials that can provide corrosion control under such environment. However, it is always advisable to use WD-40 with showpieces for corrosion control, just to be safe.
Welding Instead of Bolting
Have you ever seen a joint that is being held, in its place, with a rusted screw? Don’t you wish, on such sightings, for joints to be welded? Designers need to keep this in mind when designing. Why? Well, it is because bolts and screws get rusted fast, owing to the moisture that they accumulate. What this means is that metallic designs should only involve bolts if they are absolutely needed. Even then, adequate spaces need to be left for air circulation so that moisture doesn’t accumulate easily and, hence, the corrosion is delayed.
When you look at the measures that designers can take for corrosion control, you cannot help but notice that WD-40 does the job easily. It does wonders.
