Anchor flange

An anchor flange is a device installed on a pipeline to combat axial movement.

Anchor flange

Welded into the line and encased in concrete, they immobilize the pipe at predetermined locations and transfer built-up stresses to external structures. For example, in cross-county pipelines end forces of considerable magnitude are generated by internal pressure and temperature changes. A 24" O.D. x 0.594" wall pipe in a pipeline operating at 1100 psi and subjected to a 90° rise in metal temperature, for example, will develop total thrust of 1,000,000 lbs.

Unless these forces are properly controlled, they can damage pumps, valves and other close-tolerance equipment. Anchor Flange may be used to secure subsea piping and risers to platform structures.

The Anchor flange is designed for immobilization of high pressure pipe lines.

The Anchor flange is a one-piece combination reducer and welding neck flange designed expressly for effecting pipe size increases at flanged connections to pumps, valves, compressors and other equipment. It provides a more compact, more efficient and frequently a more economical means than is permitted by the conventional two-piece combination of a concentric reducer and welding neck flange.

What is An anchor flange?

An anchor flange is a device installed on a pipeline to combat axial movement. Resembling a collar, once it is attached to a pipe, the anchor flange is commonly anchored into a concrete foundation. Typically placed onto a section of pipeline as it makes a turn or is at a bridge crossing, the anchor flange is used to prevent the pipeline from moving.

Application of An anchor flange
APPLICATION OF AN ANCHOR FLANGE

As we know, the steel piping system could move and shake when the liquid flowing through the pipe, especially when the piping system is turning in some places, the liquid will push the turning in the direction of liquids flowing. Another application of the anchor flange, there may bring expansion movements when temperature is changing in the piping system.

Custom Anchor flange

Anchor flange are corrosion resistant and have a wide variety of uses. We carry a variety of threaded flanges, weld neck flanges and slip- on flanges and, of course, we can can custom build steel flanges to your specifications.

Specialty flange

Except the most used standard flanges, there are still a number of specialty flange such as:

Spectacle Blind Flange
Spectacle Blind Flange
Spectacle Blind Flange consist of a connected ring and a plate.

Screwed Flanges
This flange is referred to as either threaded or screwed.

Weldoflange, Nipoflange

Orifice Weld Neck Flanges
Orifice Flanges
Orifice Flanges generally come with either Raised Faces or RTJ (Ring Type Joint) facings.
Long Weld Neck Flange
Reducing Flange
Reducing Flange is used on projects that require the fitting together of different sized pipes.
Expander Flange
Expander Flange
Expander Flange is using a separate reducer-welding neck flange combination.
Anchor flange
Weldoflange / Nipoflange
Weldoflange / Nipoflange is a combination of a Welding Neck flange and a supposedly Weldolet or Nipolet.
Large Diameter Flanges
Large Diameter Flanges
The large diameter flange is used to connect or to block off two very large diameters sized pipes.
NW Long Weld Neck Flanges
NW Long Weld Neck Flanges
Long weld neck flange is also call integral flange, it means a welding neck flange has a very long neck.
