FLANGES
A flange is a plate or ring that attaches to a pipe or valve with the purpose of providing extra support for strength, blocking off a pipeline, implementing a secure attachment of other items, and more. They are usually welded to or secured with studs and nuts and can be found at the end of various pipeline connections.
Our flanges can be customized to meet any specifications and are always manufactured according to international standards such as ANSI or ASME and many more. The most common ANSI/ASME pressure classes are 150#, 300#, 400#, 600#, 900#, 1500#, and 2500#.
Flanges are manufactured in a variety of materials including stainless steel, cast iron, aluminum, brass, bronze, plastic, and other specialized metals. The most commonly used material is forged carbon steel which we can provide with a machined surface.
The three main types are Welding Neck, Socket Welded, or Blind Flanges.
WELDING NECK FLANGES
Welding Neck Flanges are easy to recognize because of their extended neck that provides important reinforcement. They are used in several applications including high pressure and sub-zero or elevated temperatures. They are commonly found when branching pipes from a tank or vessel. Welding neck flanges allow for a smooth transfer of stress between the flange and pipe.
“Long” welding neck flanges acts as an extension and is longer than the standard weld neck flange. This allows even easier access to a tank or vessel and sometimes replaces small sections of piping. Both types of welding necks allow for easy assembly and disassembly as needed for repair and maintenance.
SOCKET WELD FLANGES
Socket weld flanges are popular for small-bore, high-pressure pipes, but can also be found in larger, low pressure piping systems as well. These flanges are attached by inserting the pipe into the socket end, providing stability, and then connected with a fillet weld around the top of the connection. This allows for a better flow of the fluid or gas in the pipe.
BLIND FLANGES
Blind Flanges are manufactured without a bore and are used to block off the ends of piping, valves, and other pressure vessel openings. From the standpoint of internal pressure and bolt loading, blind flanges are the most highly stressed of all. They are also used for pressure testing the flow through a pipe system. In addition, blind flanges allow for easy access into the piping system if there is any repairs or maintenance that needs to be done.
