• Description:
• ● A threaded pipe flange is a round disc with female threads in the center and cut-outs for bolts around the perimeter.
• ● A pipe flange is a protruding circular rim with a bore in the center and surrounded by cut-outs for bolts.
• ● A threaded flange has a female internal thread to attach to a pipe or male threaded fitting.
• ● It has by 4 cut-outs for bolts to connect with another flange or surface.
• ● Stainless Steel ANSI150# Flange. 
• Used for:
• ● A threaded pipe flange, also called a screwed flange, is used to connect pipes, valves, fittings, and other equipment.
• Advantage:
• ● A flange facilitates a very secure connection between components.
• ● Threaded flanges connect pipes, fittings, and other components without the need for welding.
• ● A flange is designed to make a standardized connection and therefore an easy interchangeability between pipes and other components.
• ● This means that these flanged fittings make for easy installation and disassembly.
• ● They also have the added benefit of preventing leaks as they make a secure joint utilizing bolts and a gasket.
• To Install:
• ● Bring two flange faces together, ensuring the bolt holes are aligned. 
• ● Insert a gasket on the raised surface between the two flange faces and make sure the entire mating surface is covered to create a seal.
• ● Install and fasten bolts in the 4 cut-outs around the flange perimeter.
• ● The female thread in the center will thread onto a pipe or male threaded fitting.
• Sizing:
• ● Threaded pipe flanges are sized according to the size of the thread they will connect to.
• ● For Example: a 1/2" pipe flange will thread onto a 1/2" male pipe thread.
• Also Called:
• ● Stainless Steel Pipe Flange 150# ANSI.
• ● Ansi Flange 150.
• ● NPT Flange.
• Parts of a Flange:
• ● Flange Hub: Located in the center, it is the part of the flange that contains the bore, which is an internal female threaded opening, or a socket.
• ● Bolt Holes: Circular holes located around the central bore used to receive the bolts and secure the flange.
• ● Flange Face: The flat surface that houses the gasket and connects to the corresponding flange face that it connects to.
• Pressure Rating:
• ● 150 PSI.
• Assembly Options:
• ● Thread onto a  Type F Coupling to create a camlock x flange.
• ● Thread onto a Street Elbow to make a 90 degree elbow x flange.
• ● Thread onto a Hose Barb to make a hose barb x flange.
• ● Thread onto a King Nipple to make a king nipple x flange.
• ● Scroll down to "Related Products" for more options of pipe fittings to thread into flanges. 
• Material of Construction:
• ● These threaded flanges are constructed out of Stainless Steel 304.

More Information:

A threaded pipe flange is a metal fitting used in industrial applications to connect two pipes, fittings and other equipment without the need for welding. A pipe flange fitting is circular disc with female threads in the center and bolt holes around the circumference. A flange fitting has three parts which all serve a specific function: the threaded bore, the bolt holes and the flange face. The threaded bore, (also called the flange hub), is the internal threaded hole in the center of the flange. The bolt holes are circular holes found in the circumference of the flange around the threaded bore, and they are used to secure the flange to another flange or surface with bolts. The flange face is the mating surface where the gasket is installed, it is the flat surface that connects to another flange. To install a flange with you will need to bring the two corresponding flange faces together making sure the bolt holes are aligned, then place a gasket between them, and then insert and tighten the bolts around the perimeter to create a sealed joint. The three parts of a flange connection are the pipe flange, the gasket and the bolts. The advantage of a threaded flange is that it requires no welding since they are bolted together. This makes them quicker and easier to install and dissembled when compared to welding. They are often used in low pressure applications or in explosive applications where welding is not possible. These NPT flanges have tapered National Pipe Threads (NPT Threads), which form a secure, leak-proof connection when threaded with corresponding male NPT threads. This is why they are also called a screwed flange since the thread or screw onto a pipe, fitting or other component. This makes SS pipe flange ideal for a wide range of industrial applications including, plumbing, water treatment, oil and gas, and the chemical industry wherever welding is not permitted or where a secure leak resistant connection is needed or frequent disassembly is required. These metal flanges are manufactured out of stainless steel 304, making them durable, rust  and corrosion resistance.
