Orifice flanges

Orifice Flanges are used with orifice meters for the purpose of measuring the flow rate of either liquids or gases in the respective pipeline. Pairs of pressure "Tappings", mostly on 2 sides, directly opposite each other, are machined into the orifice flange. This makes separate orifice carriers or tappings in the pipe wall unnecessary.

Orifice Flanges generally come with either Raised Faces or RTJ (Ring Type Joint) facings. They are, for all intensive purposes, the same as weld neck and slip on flanges with extra machining.

The image on the right shows a set Orifice Flanges, where a Orifice Plate is mounted and a jack screw is machined. This jack screw is used to facilitate separating the flanges for inspection or replacement of the

Orifice Plate and gaskets.

The range of orifice flanges covers all standard sizes and ranges, and all common flange materials. Flanges are available in Welding Neck, Slip On, and Threaded form, and are typically supplied with two 1/2" NPT tappings in each flange.



A Swivel Ring Flange allows easy alignment. An important and critical feature when bolting sub sea pipeline Flanges together for example.



The outer ring Flange of the Swivel Ring Flange assembly is held in position by a retainer ring that freely rotates around the inner weld-neck hub for quickly positioning the bolt holes of the two joining Flanges.



By allowing full rotational adjustment to align flange bolt holes, the swivel ring flange greatly simplifies the final tie-in process. However, the simplicity of the swivel ring flange concept belies the fact that this specialized device must accommodate considerable tangential, shear, and rotational moment loads for installation and long-term service conditions.



Alignment is an important and critical feature when bolting subsea pipeline flanges together. The outer ring flange of the swivel ring flange assembly is held in position by a retainer ring that freely rotates around the inner weld-neck hub for quickly positioning the bolt holes of the two joining flanges.



The Swivel-Ring Flange permits 360° rotation of an outer ring around a hub, to allow easy alignment of bolt holes when attaching to a mating standard flange.



These designs, to ASME and BS5500 codes, are fully supported by corroborative calculations and accommodate the use of hydraulic bolt tensioning equipment. Hundreds of these items have been manufactured for the offshore industry over the past ten years.

Most material grades and testing conditions can be accommodated.





Spectacle blinds

Spectacle Blinds are generally applied to permanently separating pipesystems, or just to connect with each other. A Spectacle Blind is a steel plate cut into two discs of a certain thickness.

The two discs are attached to each other by section of steel similar to the nose piece of a pair of glasses. One of the discs is a solid plate, and the other is a ring, whose inside diameter is equal to that of a flange.

Spectacle Blinds be applied in systems, which regularly need to be separated from other installations. Normally, a Spectacle Blind is mounted in the "open" position so that flow through the pipe is possible. If the Spectacle Blind in the "close" position is rotated, the pipe is blanked off and no flow is possible.








Standard Met︰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.

WELDING NECK ANCHOR FLANGES
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. 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 Flanges may be used to secure subsea piping and risers to platform structures.

One of the common traits of a metal pipeline is its inherent movement caused by the flow of liquid through the pipe, as well as from the expansion and contraction caused by temperature changes. When a pipeline makes a sharp turn, the flow of liquid inside of the pipeline attempts to push the pipe in the direction of the flow. By placing an anchor flange on the pipeline and securing it into position by locking it in a concrete pillar buried deep into the ground, the forces pushing against the pipe are displaced into the earth.

Another area where an anchor flange is commonly used in a pipeline is at river and bridge crossings. Left unanchored, a pipeline has the tendency to sag when crossing large expanses. This is caused from the weight of the liquid flowing inside of the pipeline. By placing an anchor flange at each side of the crossing, the pipeline is held firmly in place and prohibited from moving. The friction of fluid moving through the pipeline will attempt to push the pipeline out of position over time, if not for an anchor.

The same aspects of movement in a large pipeline are duplicated in smaller versions of hydraulic hard line. As the hydraulic fluid is heated, the hydraulic hard line begins to expand and contract. When anchoring a hydraulic line on a machine or in a machine shop, placing an anchor flange in concrete is not an option. The anchor used in this type of application is commonly secured by bolting the anchor to the machine or the building. This requires a flange that resembles a bearing block, with a bolt hole drilled into each corner of the anchor block.

The most common method of fastening a flange to a pipeline or a hydraulic line is to weld the flange solidly into position. This allows the installer to accurately position the flange onto the pipeline where it will offer the most success. When sealing the anchor flange in cement, the concrete is typically poured around the flange and the pipeline after the flange has been welded onto the pipeline.

Norsok L005 Compact Flange

ISO/TC 67/SC 4 Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries — Drilling and production equipment-Compact flanged connections

The first original Compact Flange designed in full accordance with ASME ANSI BS 8010, Type Approved & Fire Tested.

The Connector is designed to meet ANSI B 16.5, ASME VIII, API 6A/Q1 and other design codes. The design has the approval of Lloyds, DNV and Stoomwezen. Fully fire tested in accordance with API 6FB parts 1 and 2. Also gas tested to meet all aspects of ASME B31.3 Chapter IX (e.g. 1400 bar at 180°C Gas test with bending).

Offering weight savings of up to 88% when compared to the equivalent ANSI Flange. Quick and easy make-up with superior mechanical strength and fatigue performance.

The Compact flange provides everything that a standard flange does not – space saving, reduced weight and, perhaps most importantly, a guaranteed leak-free connection.

The reduced dimensions of the compact flange are achieved by reducing the seal diameter, which in turn, reducesthe cross-section area of the seal faces. Second, the gasket is replaced by a seal ring which works with the seal faces, not against them, to ensure face-to-face mating, so that only low seating forces are required to compress the seal faces. With lower pressures needed, both the size and number of the bolts can be reduced, ultimately providing a smaller, lighter-weight connection – approximately 70-80 percent smaller and lighter than typical ANSI flanges.

The key advantage of the compact flange over the ANSI flange is that it will not leak, thus providing cost savings both in terms of avoiding lost product and maintenance, as well as improving health and safety. In a compact flange, only a small amount of the total bolt pre-load is used to compress the seal. The major part of the bolt pre-load is transferred through the mating flange faces, creating a static face-to-face connection unaffected by the internal pressure or the external loads acting on the flange. Once pressure-tight after assembly, a compact flange, being a static connection, will always remain pressure-tight.
