How to install a chemical seal?

Hey there! As a chemical seal supplier, I've seen firsthand how crucial it is to know how to install these seals properly. A chemical seal acts as a barrier between the process media and the pressure instrument, protecting it from corrosive, viscous, or high-temperature substances. In this blog, I'll walk you through the steps of installing a chemical seal, so you can get the job done right.

Step 1: Gather Your Tools and Materials

Before you start the installation, make sure you have all the necessary tools and materials. Here's a list of what you'll typically need:

Chemical seal: Choose the right type of chemical seal for your application. We offer a variety of seals, like the MOR 2100 Sewage Pump Seal, MOR Type8, and MOR WB2/10T/10R PTFE Bellow Mechanical Seal.
Pressure instrument: This could be a pressure gauge, transmitter, or switch.
Mounting hardware: Bolts, nuts, washers, and gaskets.
Wrenches: Different sizes to fit the mounting hardware.
Sealant: If required by the manufacturer.
Cleaning supplies: To clean the surfaces before installation.

Step 2: Prepare the Installation Site

The first thing you need to do is prepare the installation site. This involves cleaning the connection points on both the process piping and the pressure instrument. Use a suitable cleaning agent to remove any dirt, debris, or old sealant. Make sure the surfaces are dry and free of any contaminants.

Next, check the compatibility of the chemical seal with the process media. You need to ensure that the wetted parts of the seal are resistant to the chemicals in the process. If you're not sure, you can always reach out to us for advice.

Step 3: Install the Chemical Seal on the Process Piping

Now it's time to install the chemical seal on the process piping. Start by placing the gasket on the flange of the process piping. Make sure the gasket is centered and in good condition.

Then, align the chemical seal with the flange on the process piping. Insert the bolts through the holes in the flange and the seal, and hand-tighten the nuts. Don't fully tighten them yet.

Use a torque wrench to tighten the nuts to the manufacturer's recommended torque value. Tighten the nuts in a criss - cross pattern to ensure even pressure distribution. This will prevent leaks and ensure a proper seal.

Step 4: Connect the Pressure Instrument to the Chemical Seal

Once the chemical seal is installed on the process piping, it's time to connect the pressure instrument to the seal. Similar to the previous step, place a gasket on the flange of the chemical seal.

Align the pressure instrument with the flange on the chemical seal. Insert the bolts through the holes and hand - tighten the nuts. Again, use a torque wrench to tighten the nuts to the recommended torque value in a criss - cross pattern.

Step 5: Fill the Chemical Seal with Filling Fluid

Most chemical seals need to be filled with a filling fluid. The filling fluid transfers the pressure from the process media to the pressure instrument. The type of filling fluid depends on the application, such as the temperature range and the chemical compatibility.

Follow the manufacturer's instructions to fill the chemical seal with the appropriate filling fluid. Usually, there's a filling port on the seal. Use a syringe or a filling device to inject the fluid slowly until the seal is properly filled. Make sure to remove any air bubbles from the system.

Step 6: Test the Installation

After the installation is complete, it's important to test the system to ensure there are no leaks. You can do a pressure test by applying a small amount of pressure to the process piping.

Check all the connection points for any signs of leakage. If you notice any leaks, you may need to tighten the nuts a little more or replace the gasket.

Once you're sure there are no leaks, you can start the process and monitor the pressure readings on the instrument. Make sure the readings are accurate and stable.

Step 7: Maintenance and Troubleshooting

Regular maintenance is key to ensuring the long - term performance of the chemical seal. Check the seal and the connections periodically for any signs of wear, corrosion, or leakage.

If you encounter any problems, such as inaccurate pressure readings or leaks, don't panic. First, check the connections to make sure they're tight. If the problem persists, it could be an issue with the filling fluid or the seal itself. You can always contact us for troubleshooting advice.
