Hey there! As a supplier of chemical seals, I often get asked about the best installation locations for remote-mounted chemical seals. Well, in this blog, I'm gonna break it down for you and give you the lowdown on where these bad boys should go.
First off, let's talk about what chemical seals are. They're basically protective barriers that prevent process media from coming into direct contact with pressure-measuring instruments. This is super important because some chemicals can be corrosive, viscous, or have solids in them that could damage the instrument. Remote-mounted chemical seals allow you to place the pressure sensor away from the harsh process environment, which can extend the life of the instrument and improve measurement accuracy.
Installation in Piping Systems
One of the most common places to install remote-mounted chemical seals is in piping systems. When you're dealing with a flowing process fluid, it's crucial to choose the right spot. For horizontal pipes, the ideal location is on the side of the pipe. This helps to prevent any gas bubbles or solids from accumulating in the seal chamber. If you install it at the top of the pipe, gas bubbles can get trapped, which can lead to inaccurate pressure readings. And if you install it at the bottom, solids can settle, causing blockages.
In vertical pipes, the installation location depends on the direction of the fluid flow. If the fluid is flowing upwards, you can install the seal on the side of the pipe. But if it's flowing downwards, it's better to install it at a slight angle to prevent solids from building up.
Tanks and Vessels
Tanks and vessels are another common place for chemical seal installation. When installing on a tank, you need to consider the level of the liquid inside. For liquid-level measurement, the seal is usually installed at the bottom of the tank. This allows you to accurately measure the pressure exerted by the liquid column, which can then be used to calculate the liquid level.
If you're measuring the pressure inside a vessel with a gas or vapor, the seal can be installed on the side or top of the vessel. Just make sure it's in a location where it won't be affected by any turbulence or agitation inside the vessel.
Reactors and Mixers
In reactors and mixers, the installation location can be a bit trickier. These environments are often highly dynamic, with high temperatures, pressures, and agitation. For reactors, the seal is typically installed on the side of the vessel, away from the agitator. This helps to avoid any mechanical stress on the seal caused by the agitation.
In mixers, the seal should be installed in a position where it can accurately measure the pressure without being affected by the mixing action. This might mean installing it on the side of the mixer, at a distance from the impeller.
Special Considerations
There are also some special considerations when it comes to installing remote-mounted chemical seals. For example, if you're dealing with a high-temperature process, you need to make sure the seal and the filling fluid can withstand the heat. Some seals are designed with special materials and filling fluids that can handle high temperatures.
Another consideration is the viscosity of the process media. If the media is very viscous, you might need to use a seal with a larger diaphragm or a different type of filling fluid to ensure accurate pressure transmission.
Product Recommendations
We offer a wide range of chemical seals that are suitable for different installation locations and process conditions. For example, our MOR 2100 Sewage Water Pump Spring Seal is designed for use in sewage water pumps. It can handle the corrosive and abrasive nature of sewage water, making it a great choice for this type of application.
Our Equivalent to type 2 mechanical seal is a versatile seal that can be used in a variety of industrial applications. It's designed to provide reliable performance and long service life.
And if you're looking for a mechanical seal for a centrifugal pump, our MOR 58U 59U Mechanical Seal for Centrifugal Pump is a great option. It's designed to handle the high pressures and speeds of centrifugal pumps.
Conclusion
So, there you have it! The installation locations for remote-mounted chemical seals depend on the type of process, the characteristics of the media, and the specific requirements of the application. By choosing the right installation location and the right chemical seal, you can ensure accurate pressure measurement and long-term reliability.
