The design allows for easy alignment during installation and accommodates slight variations in pipe dimensions. ASME B16.48 compliant slip-on flanges find extensive use in low-pressure applications and situations where ease of installation takes priority over extreme strength requirements.

The versatility of slip-on stainless steel pipe flange configurations makes them popular in process industries, water treatment facilities, and general industrial applications. While they require two weld joints compared to the single weld of welding neck flanges, their lower material cost and easier machining often make them the economical choice for non-critical services.

Socket Weld Flanges for Small Bore Piping

Socket weld stainless steel flanges provide excellent performance in small bore piping systems where threaded connections would be impractical and full welding neck flanges would be unnecessarily expensive. The socket design provides a shoulder for the pipe to rest against, ensuring proper weld gap and facilitating alignment during installation. These flanges are easily accessed for inspection, cleaning, or modification, making them valuable in systems requiring periodic maintenance.

The single fillet weld required for socket weld flange installation provides smooth bore conditions with minimal flow restriction. This characteristic makes them particularly suitable for instrumentation piping, sampling systems, and applications involving viscous fluids or slurries where internal crevices could trap material.

Blind Flanges for System Termination

Blind flanges serve the critical function of sealing the end of a piping system or pressure vessel opening. B16.47 SS blind flanges can be utilized as plates meant to cover or close pipe ends, providing access points for future expansion or serving as inspection ports. The solid disc construction of blind stainless steel flanges withstands full system pressure while enabling quick access to internal components when bolts are removed.

These termination flanges find applications in numerous scenarios including temporary pipeline endings, nozzle blanking on pressure vessels, and creating access openings for equipment maintenance. The ability to quickly open and reseal a system by simply removing and reinstalling a blind flange significantly reduces downtime compared to cutting and rewelding pipe sections.

Welding Neck Flanges for High-Pressure Service

Welding neck stainless steel flanges represent the strongest and most reliable flange type available for high-pressure and high-temperature applications. The long tapered hub provides excellent stress distribution from the flange to the pipe wall, making these flanges suitable for critical services involving extreme conditions, cyclic loading, or thermal transients. ANSI B16.5 SS pipe flanges in welding neck configuration serve in applications ranging from power generation facilities to petrochemical processing units.

The smooth transition between pipe and flange in welding neck designs minimizes stress concentrations and reduces the risk of fatigue failure in cyclic service. While more expensive than slip-on or socket weld types, welding neck flanges justify their cost in applications where safety and reliability cannot be compromised.

Stub End Flanges and Lap Joint Systems

Stub end flanges combined with lap joint backing flanges create a unique connection system particularly valuable when frequent disassembly is required or when connecting dissimilar metals. The stub end, manufactured from the same material as the pipe, provides the corrosion-resistant surface while the backing flange handles mechanical loads. This configuration enables the use of carbon steel backing flanges with stainless steel stub ends, reducing material costs in large diameter applications.
