SS Flanges - Stainless Steel Flanges

Long tapered hub that provides a smooth transition from the pipe to the flange. Best choice for high-pressure, critical service, and thermal cycling applications. Butt-weld connection ensures maximum strength.

• Best for high pressure service
• Excellent for thermal cycling
• Full bore flow path

Slides over the pipe and is welded both inside and outside diameter. Easier alignment and lower machining costs. Suitable for lower pressure applications and where frequent disassembly is needed.

• Easy pipe alignment
• Lower cost option
• Good for frequent maintenance

Socket holds the pipe in position with a socket weld fillet. Provides a strong connection similar to butt-weld but with easier alignment. Typically used for small diameter high-pressure piping.

• Strong welded connection
• Good for small diameters
• High pressure rated

Internal NPT/BSPT threads allow quick connection without welding. Ideal for low-pressure service, temporary installations, and areas where welding is not possible.

• No welding required
• Quick installation
• Lower pressure ratings

Solid plate flange used to close the end of a pipe or vessel. Can be removed for inspection or future extension. Used as termination points or for pressure testing.

• Pipe termination
• Pressure testing
• Future expansion

Used with a stub end and backing ring. The flange slides over the stub end and is not welded to the pipe. Ideal for applications requiring frequent disassembly or where pipe alignment is critical.

• Frequent disassembly
• Pipe alignment flexibility
• Lower bolting stress

Specialized flange with a concentric or eccentric hole for flow measurement using an orifice plate. Available with pressure tapping points for differential pressure measurement.

• Flow measurement
• Differential pressure taps
• Flow rate calculation
