Flange

Blind Flange View All

A blind flange is a round plate which has all of the relevant blowholes except center hole, and because of this feature the blind flange is usually used to close off the ends of a piping systems and pressure vessel openings. It also permits easy access to the interior of a line or vessel once it has been sealed and must be reopened. Read more about Blind Flange

Lap Joint Flange View All

A lap joint flange is very similar to a slip-on flange, with the main difference being that it has a curved radius at the bore and face to house a lap joint stub-end. Lap joint flanges and stub-end assemblies are typically used in situations where requires frequent dismantling for examination. Read more about Lap Joint Flange

Orifice Flange View All

Orifice flanges are applied for metering the volumetric flow rate of liquids and gasses through a pipe. Two orifice flanges are called an orifice flange union. Each flange comes with two pipe taps for measuring the pressure drop of the flow through an orifice plate. Orifice plates do not come with the flanges and are sized based on the requirements of the process. Two jack screws are used to spread the flanges apart in order to change the orifice plate. This flange is normally available in weld neck, slip-on, and threaded flanges. These flanges have a raised face. Read more about Orifice Flange

Slip-On Flange View All

Slip on pipe flanges are typically provided with a raised or flat face. When a raised face is necessary for slip on pipe flanges, the standard height is 1/16 inch for slip on pipe flanges fewer than 400#. For slip on pipe flanges of 400# and up, the standard slip on pipe flange raised face height is 1/4 inch.Read more about Slip-On Flange

Socket Weld Flange View All

The socket weld flange is generally applied on pipes with smaller sizes but high pressure. These pipe flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. Slip on Pipe flanges with a hub has published specifications that range from 1/2 inch to 24 inch.Read more about Socket Weld Flange

Threaded Flange View All

Threaded Flanges are similar to slip-on flanges in outline, but the bore is threaded, thus enabling assembly without welding. This obviously limits its application to relatively low pressure piping systems. Threaded Flanges may be welded around the joint after assembly, but this is not considered a satisfactory method of increasing the flanges' pressure applications. Threaded flange use in low press condition usually.Read more about Threaded Flange

Weld Neck Flange View All

A weld neck flange consists of a circular fitting with a protruding rim around the circumference which is generally machined from a forging, these flanges are typically butt welded to a pipe. The rim has a series of drilled holes that permit the flange to be affixed to another flange with bolts. Such flanges are suitable for use in hostile environments that have extremes of temperature, pressure or other sources of stress.Read more about Weld Neck Flange

Anchor Flange View All

Anchor flanges are important elements in many thrust-control systems, especially those protecting pipeline pumping stations. Welded into the line and encased in concrete, they immobilize the pipe at predetermined locations and transfer built-up stresses to external structures.Read more about Anchor Flange

Plate Flange View All

The plate flange has a circular disk that is welded onto the end of a pipe and allows it to be bolted to another pipe. Typically used in fuel and water pipelines, the two flange plates will be bolted together with a gasket in between them. The flange plate will have bolt holes all around the perimeter and will be used to create junctions, tees and joints.Read more about Plate Flange

Ring Flange View All

The ring flange is a special flange type that includes an extra sealing element sandwiched between the two plate faces. A shallow groove is machined into the flange plate faces, typically towards the center of the plate below the row of tensioning holes. These flanges usually come in sets that include a separate sealing ring of the same dimensions as the groove. These rings may be made of rubber compounds, fiber, or soft steel, and are round or square in cross section. They are also of a slightly larger diameter than the combined depths of the two grooves.Read more about Ring Flange
