Stainless Steel Valve Connection Types

Stainless Steel Valve Connection Types are critical for controlling the flow of liquids and gases in industrial facilities. Different connection types ensure that valves are connected to pipelines securely and without leakage.

Threaded Connections

• NPT (National Pipe Thread): A tapered threaded connection type commonly used in the United States. It requires Teflon tape or sealant for leak-proof sealing.
• BSP (British Standard Pipe): A parallel or tapered threaded connection type commonly used in the UK and Europe. Parallel threaded connections require a sealing gasket.
• Metric Thread: Metric threaded connections manufactured according to ISO standards, commonly used in Europe.

Flanged Connections

• Weld Neck Flange: Ideal for high-pressure and high-temperature applications. It is connected to the pipeline by welding.
• Slip-On Flange: A suitable and economical option for medium-pressure and medium-temperature applications. It is connected to the pipeline by welding.
• Threaded Flange: Can be easily connected to threaded pipelines. A gasket is required for sealing.
• Blind Flange: Used to close the ends of pipelines.

Welded Connections

• Weld Neck Connection: The most reliable connection type for high-pressure and high-temperature applications. It is connected to the pipeline by welding.
• Socket Weld Connection: A suitable, fast, and easy connection type for small-diameter pipelines.

Clamp Connections

• Tri-Clamp Connection: A connection type that is easy to assemble and disassemble, especially preferred for hygienic applications.
• V-Band Connection: A leak-proof connection type suitable for high-temperature and high-pressure applications.

Selecting the Connection Type

The selection of a valve connection type should be made carefully according to application requirements. The following factors should be considered:

• Pressure and Temperature: For high-pressure and high-temperature applications, welded or flanged connections should be preferred.
• Fluid Type: Stainless steel or special alloy valves should be used for corrosive or abrasive fluids.
• Pipeline Diameter: The valve connection type should be compatible with the pipeline diameter.
• Ease of Installation and Maintenance: Clamp or threaded connections can be preferred for valves that need to be frequently assembled and disassembled.
• Cost: The cost of the connection type should also be considered.
