How Does The Protective Coating Extend Valve Life?

How Does The Protective Coating Extend Valve Life?

Valves are useful in several places. The number of valves used in an industry could reach hundreds or even thousands, depending upon the size where they’re used. When the number is so huge, it also involves other areas of concerns.

It is not just about buying the valves when the number is significant, you also need to concern yourself with maintenance and caring of the valves. Today, valves are so important that they have actual maintenance plans. There are also additional features to maximize valve performance and also extend their lifespan. One such example is the coating of valves. Valves can have a protective coating, and that can extend their lifespan and improve efficiency.

What Is A Protective Coating?

Adding a protective coating to a valve is helpful, but what exactly does this mean? 

Covering your valve with additional protective material to save it from corrosive materials is termed as protective coating. There are some places where valves are used and exposed to corrosive materials. The coating is placed in pumps to extend their life and reduce erosion and corrosion.

The protective coating also reduces the overall consumption of energy. This happens if the coating is of a low surface energy characteristic as it reduces the frictional resistance for flowing.

What Should be Considered Before Deciding On Protective Coating?

A lot of people are confused about what should be considered to decide whether to go for a coating or not. It is not that difficult, and neither is it just a cost thing. There are multiple factors which come into play. Let us take a look at some of these factors:

Cost-Benefit Analysis

This is a must for anything you buy. You need to check on how much you pay versus the benefit you reap. This eventually tells you if the buy is worth it. You cannot choose to coat if there are hardly any benefits but a considerable cost.

The Urgency Of The Component

How critical is the valve in the entire process? Does the process primarily rely on the valve? If any failure on the valve will cause a direct impact on your production and halt the process, it is advisable to get the valves protectively coated because that would save the valve and extend its life.

Chances Of Failure

This is one of the important points. What are the chances that the valve will fail? If the environment is conducive to valves failure, the decision is clear. Check the conditions and decide whether the chances that valve might fail without coating are high. If the answer is yes, you know you need that valve to smoothly function.

Other Factors

There are other factors which can also help you decide whether you need the protective coating or not. Some of them are as below:

-    Gas or fluid components, chemicals used, pH
-    Temperature used
-    Design pressures used
-    Overtime or turbulence
-    Operational usage

How Does The Protective Coating Benefit?

You must also know the additional benefits that come through from using the protective coating on valves. These benefits depend upon the type of processes, but most are universal:

Increases Useful Life

When you buy a new industrial valve, it works efficiently and with consistency. However, as the life of the valve rises, it is also subjected to exposures which reduce the performance. The natural life of the valve gets shortened due to external forces. Whereas, with a protective coating, the valve is protected against exposure. Hence, the valve’s life and efficiency are prolonged.

Prevents From Corrosive Material

A valve can be in a place where there has excessive usage of corrosive material. For example, in oil fields. Valves are exposed to corrosive materials and chemicals at the facility, and the chances for failure are high. In such conditions, a protective coating is the best option. It will help to prevent the valve from wearing out.

Reduces Consumption

Valves are also useful in converting energy into another useful form.   coating, there will be an advantage on the sense that the energy consumed by the valve to operate will be less as compared to an ordinary situation. This would mean that using the same amount of energy; operations are more productive. This is a tangible advantage of protective coating on valves.

Easy To Maintain

Valves require maintenance. There are different plans through which the maintenance of valves is done. With protective coating in place, valves will not require as frequent maintenance as usual. This means less cost of maintenance and hence, savings. Also, with a protective coating, valves don’t need to be handled with too much caution as the coating protects them.

Reliable

If you are getting a protective coating done, it should be done by a reliable valve supplier. This will provide you a surety that the coating is genuine and suits the environment in which the valve works. 

Conclusion


These are some of the ways the protective coating can help to extend the valve life and in turn, benefit the process in numerous ways. The key here is to identify the cost and matching it with the significance of the component. Hopefully, this article helps you to decide on whether the protective layer is required or not.
