Discussion on the inlet and outlet connection methods of steel lined PTFE storage tanks

The inlet and outlet connection methods of steel lined PTFE storage tanks are important in design and selection, as they directly affect the use, maintenance, and connection to other equipment in the process flow. Here are some common import and export connection methods:

1. Flange connection: It is a common connection method suitable for connecting pipelines, valves, and other equipment. Flange connections are usually composed of flanges, bolts, gaskets, etc., which are fastened with bolts to maintain sealing. This connection method is sensitive, easy to maintain and disassemble, but requires good sealing performance.

2. Threaded connection: It is suitable for smaller diameter pipes and connections. Through threaded connections, it can be quickly connected and disassembled, but compared to flange connections, the sealing performance may be poor.

3. Welding connection: It is commonly used for fixed, pressure resistant, or high-temperature applications. Welding connections can ensure sealing performance, but may require more time and effort for maintenance or replacement.

4. Quick connector: It is a convenient connection method suitable for situations that require frequent connection and disassembly. They are commonly used in fluid transmission systems, such as hose connections.

5. Concave convex ring connection: It is a simple connection method suitable for applications with low pressure or non sealing requirements.

When choosing the import and export connection method, the following factors need to be considered:

1. Process requirements: Select a suitable connection method according to the process requirements of the steel lined PTFE storage tank to ensure the normal flow of fluid transmission.

2. Operational performance: Consider the ease of operation of the connection method to facilitate maintenance and operation.

3. Sealing: Ensure that the connection method can provide the required sealing performance to prevent leakage.

4. Material compatibility: Ensure that the materials used in the connection method are compatible with the stored substances and process environment to avoid corrosion or other issues.

5. Maintenance and replacement: Consider the impact of connection methods on maintenance and replacement to ensure the convenience of future operations.

The selection of appropriate import and export connection methods needs to be determined based on specific application and process requirements. It is important to consult with engineers or manufacturers during design and selection.
