Getting to Know the Reasons Why Valves Should Get More Consideration in Industrial Pipings

When putting into perspective the general industrial piping system structure and material selections, the key considerations will fall into two categories: pipes and fittings. The highlight is usually on the pipe and fitting materials’ compatibility, pressure, and temperature characteristics.

Choosing valves are often overlooked and only considered when the main decisions are settled. However, valve selections can be overwhelming as there are many types available, including butterfly valves, gate valves, check valves, ball valves, globe valves, and more. In addition, valves can vary significantly in a system depending on the piping system’s purpose.

All the same, valves are essential to any successful system because they regulate the flow of media. Also, they deserve greater attention regarding material options since a system is only as strong as its weakest component.

Valves’ Purpose

Generally, valves regulate, restrict, or control the fluid flow through a piping system. More particularly, a valve system may be in place to:

  • Regulate and be in charge of the water cooling rates through cooling lines to manage the temperature.
  • Restrict flow for balancing the system.
  • Control the flow of concentrated bases or acids passing through a line.
  • Redirect media flow from one line to another at a three-way valve.
  • Can prevent reverse flow through the use of check valves.
  • Automatically stop the flow when there is a system failure.

Importance of Valves

With such a massive role in improving safety, increasing efficiency, and keeping systems up and working, why are valves hardly discussed before designing a piping system?

For one reason, it may be the minimum cost incorporated with valves, particularly when compared to the overall cost of an extensive pipes and fittings system. But systems can become more reliable, efficient, and cost-effective by evaluating valve selections of different materials earlier in the material selection and planning process.

Valves’ Significance in System Efficiency, Reliability, and Cost

There is a general conception that the weakest point in any industrial system occurs at the valves. However, this is not always the case. Tons of valves can uphold similar performance standards as the rest of the piping system, but this will solely rely on the chosen valve material, pipe and fitting material, and joining method.

  • Corrosion Susceptibility

Whenever working with acidic or caustic solutions, increasing the life of a machine’s system is important. Among others, unfortunately, corrosion is one of the culprits of several system issues, which causes costly downtime, premature repairs, or even complete replacement. Each setback results in significant costs and enough reason for engineers to pursue increasing the life’s system.

Even if corrosion does not damage a system to the point of needing urgent repairs, it can harm the pipes and valves. What is more, valves are susceptible to both degradation and corrosion of valve seats. The latter creates debris and scale that can make valves less efficient, move more difficult, or cause huge security concerns in the course of a failure.

  • Pressure Loss

Industrial systems should optimize fluid dynamics in order to avoid unnecessary power consumption expenses. One example is to reduce head drop or pressure drop.

One ground of pressure drop in the piping system is the valves. Each valve has a known flow coefficient, which calculates the pressure drop it causes once in the full open position. This flow coefficient is the volume that will flow through the valve with a pressure drop of 1psi across the valve. The larger the valve flow coefficient, the less pressure drop it will cause.

  • System Weight and Stress

Each part attached to or incorporated in a piping system, increases stress on the pipe. More system stress heightens the possibility of leaks, breaks, misalignment, and even joint failure.

  • Pressure Rating

In terms of the pressure rating system, the part with the minimum pressure rating becomes the limiting factor of the system. More often than not, a valve inserted into the line has the most minor pressure rating, making it the limiting factor to the system’s overall pressure rating.

Note that getting more profound knowledge about valve pressure ratings is imperative because a system is only as strong as its weakest link. Despite what people assume, the valves do not have to be the system’s pressure restraint. The factors to consider for valve pressure ratings underlie in the connection type, or joining method, and material type.

Conclusion

In a nutshell, it is essential to understand the valves’ purpose in the industrial piping system. It would always be best to adhere to professionals’ recommendations in terms of pressure ratings and temperature factors. Hopefully, this article has been helpful. Good luck in finding the ideal valve and piping system for your project!
