Dismantling joints

Dismantling joints play a decisive role in the design and layout of pipelines and valves. The dismantling joints are double flanged fittings that allow longitudinal adjustment in flanged pipe systems. Thanks to this adjustability of the dismantling joint, the valve can be fitted next to the dismantling joint, and the dismantling joint can be to set to the exact length required prior to being securely connected to flanges. Dismantling joints provide a simple method for installation and removal of flanged valves so also for subsequent maintenance. Typical applications include water treatment, sewage treatment, power generation and pumping stations. The dismantling joint guarantees fast installation and removal, thus contributing to increased efficiency and reducing site operations and down time.

Technical Notes

The Design Principle

Dismantling joints

 

Dismantling Joints play a decisive role in the design and layout of pipelines and valves. They are an essential aid during the installation and removal of pipe sections and valves. Without a dismantling joint offering longitudinal adjustment, it is almost impossible to insert a valve exactly into a pipe section. Thanks to this adjustability of the dismantling joint, the valve can be fitted next to the dismantling joint, and the dismantling joint can be to set to the exact length required prior to being securely connected to flanges.

 

The high-quality rubber gasket ensures that the system is always leaktight on tightening of the nuts.

Even if there are numerous versions of dismantling joints available for different applications, the basic principle is always the same:

The flange adaptor is located on one side of the dismantling joint. It is connected securely to the pipe or valve via the flange. Flange bore holes corresponding to the respective pressure rating or standard are available.

For the installation and removal of valves with longitudinal adjustment of maximum ± 25 mm, these two parts can be pushed against one another so that the dismantling joint can be inserted between the pipe sections or pipeline and valve.

Threaded tie-rods are used for the subsequent restraining and flange connection, depending on the type of dismantling joint used.

Advantage

Nsure that the hose meets the published levels.

tolerances

The substantial adjustable travel of these products means the “face to face” tolerances of the equipment to be installed is no longer a concern.

length

Used to facilitate the dismantling or the reassembly of a flanged piece of equipment on a pipeline, and adjustable in length with considerable travel.

Simplify

Simplify maintenance operations because the connection is self-anchored and there is no need for concrete anchor blocks.

eqipment

Compensates for axial displacement of eqipment in a pipe line during installation and dismantling as the telescopic action between the inner and outer flange bodies allows for longitudinal adjustment.

easier

Makes placing joint rings between flanges easier, even those with inserts.

additional

The additional flange also makes a time-saving preliminary installation.

Flange

Piping components can be bolted together between flanges. Flanges are used to connect pipes with each other, to valves, to fittings, and to specialty items such as strainers and pressure vessels. A cover plate can be connected to create a "blind flange" Flanges are joined by bolting, and sealing is often completed with the use of gaskets or other methods. Mechanical means to mitigate effects of leaks, like spray guards or specific spray flanges, may be included. Industries where flammable, volatile, toxic or corrosive substances are being processed have greater need of special protection at flanged connections. Flange guards can provide that added level of protection to ensure safety.

Covers

Fasteners are used for fastening and securing materials such as wood, metal, plastic, or concrete. They include nuts and bolts, threaded rods, structural bolts, machine screws, wedge anchors, washers, rivets, and more in a variety of types and sizes, including metric and inch.

Particulate barriers/purge connectors

In systems that have a media with significant particulate content (i.e. flash or catalyst), a barrier of ceramic fiber can be utilized to prevent corrosion and restricted bellows flexibility resulting from the accumulation of the particulate. Purge connectors may also be utilized to perform this same function. Internal liners must also be included in the design if the expansion joint includes purge connectors or particulate barriers.

Liners

A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. It is a deformable material that is used to create a static seal and maintain that seal under various operating conditions in a mechanical assembly.
