Valves function in a pressurized environment while they discharge control of the flow of gases, liquids and slurry matters. To keep cost low and profitable, manufacturers supply valves in a standard range of materials to serve common exposures to last for a limited time. But giving the corrosive environment where valves operate, there is need to protect the valves from faster damage due to the unfavorable work environment, especially where the possibility of failure to environmental influences is high.
Let’s consider valves application in the service sector with high-level of corrosive aggression; such place means the need for maintenance will be more than areas with less corrosive hostility. Additional strain to the location of such valves may be the inaccessible construction www.kp-lok.com which means more care is required for the valves to last longer. Where we such situations exist there is the need for adequate protection of the valves to allow them to function longer. The best solution is to protect the valves with a coating to slow the rate of corrosion and make it last longer.
By using thermal spray coatings for valves and equipment in the high-velocity oxy-fuel environment, You can save time, money and labor. This spray will protect the equipment by restricting corrosion, wear, oxidation and sulfidation. The spray coatings are thinner and have no metallurgical bond with substrate unless they are heat treated after application. These spray coatings are cost effective to keep the equipment service for a longer time. The spray coatings also help to return your used valves to their original form and save you the money that may be used for, procuring new parts.
Therefore, when you operate in an aggressive and corrosive piping environment, there is the need to protect the equipment to extend their serving lives. But, protecting the valves and other equipment need you to understand the various factors that come to play. Understanding these factors is crucial to your success; take a look at the following factors to know what’s at stake.
- Nature of the environment. Things to watch out for include: fluid or gas composition, acidity composition, suspended solids, chemical additions, etc.
- The temperature. The presence of thermal shock or recycling and minimum, maximum and nominal temperature that exist in the location.
- Operational usage. The extent of use of the valves, how long do they work for? Do they operate continuously, occasional or intermittently?
- Maximum and nominal design pressures.
- The flow speed. Flow fluid speed, over time, and localized turbulence.
- Mission critical. How critical is the valve to the control process?
The after coating processes will alter the structure and properties of the coatings to improve the performance of the system. There will be fusing, a sintering method applied manually to create dense coats and achieve a metallurgical bond with the substrate. It reduces coating’s adhesion strength where abrasive wear or sliding occurs.
Different processes exist that enable coatings for specific uses to optimize hardness, toughness, temperature and corrosion resistance, and cost optimization. With the sustained rise in the cost of alloys, thermal spray coatings offer a cost-effective answer. The fluid control industry can depend on it for the solution to lasting valves, used in industrial machinery and equipment applications.
