When it comes to stainless steel flanges, there are 8 types that you should know about, not just in name, but also how they are used.
At Anglo Stainless we manufacture and provide all 8 types of key flanges to the industry, and below our expert team has listed the key benefits and uses of each type of flange.
Weld Neck Flanges: These flanges are notable by their protruding necks, with the weld neck flanges have the same bevel and thickness of the pipe. This flange is recommended for severe service conditions such as sub-zero or high temperatures and high pressure.
Slip-On Flanges: These are the most inexpensive variety of flange available for purchase. The slip–on flanges have a slightly larger diameter than the pipe, which makes it easier to slip them over the pipe (hence the name). These stainless-steel flanges are fillet welded to a position and are ideal for low-pressure applications.
Blind Flanges: These flanges are designed deprived of a bore, and are used to seal vessel openings or piping systems. These are ideal for piping systems or vessels that require regular inspection and can be supplied with or without hubs. Furthermore, it can easily handle high stress caused due to internal pressure.
Threaded Flanges: Used for special applications, these flanges are compatible with pipes with external threads and can be easily assembled without welding. The flanges are not recommended for applications where bending stresses, high pressure or high temperatures are involved.
Lap Joint Flanges: The lap joint flanges are the type of slip-on flanges that are used with stub end fittings. These flanges are perfect for piping systems that require regular inspection and maintenance such as low alloy steel pipes or carbon steel pipes.
Socket Weld Flanges: The flanges are intended for use on small diameter and high-pressure piping. The socket weld flanges have internal welds which contribute to their durability as well as fatigue strengths and are primarily found in the chemical processing industry.
Orifice Flanges: The function of these steel flanges is to provide access to a line for metering liquids or gases. The orifice flanges are installed with orifice plates or flow nozzles.
Ring–Type Joint Flanges: These flanges are used for high pressure and temperature applications. The ring-type joint flanges feature a groove that can be easily compressed on blind, slip-on or weld neck flange. The flanges help avoid leaks in pipelines where media is transferred at high pressure and high temperature.
