Rotating Flange Metal Bellows Axial Expansion Joint

METAL BELLOWS AXIAL EXPANSION JOINT WITH ROTATING FLANGE — FEATURES & PRICES

The metal bellows axial expansion joint with rotating flange is the type in which the metal expansion joint is connected with a rotating flange. It is widely used in hot water and steam applications, in the chemical and pharmaceutical industries, in the pulp and paper industry, as well as in oil refineries.

Thanks to its excellent sealing performance and long-term, maintenance-free operation, it offers lower investment costs and superior performance.

METAL BELLOWS EXPANSION JOINT

Metal bellows expansion joints are flexible bellows-type connection elements that absorb vibration movements or expansion–contraction caused by ambient temperature or the media inside the pipeline.

The metal expansion joint absorbs thermal expansion along the axis of the pipe. It can be used for thermal balance and mechanical expansion in all types of pipelines.

Metal bellows expansion joints are used in machinery, piping systems and pump outlet mechanisms.

TYPES OF METAL BELLOWS AXIAL EXPANSION JOINTS

Metal expansion joints come in different connection types such as rotating flange, fixed flange, weld-neck and slip-on types. These types relate to the connection method and lead to differences in installation.

METAL BELLOWS AXIAL EXPANSION JOINT WITH ROTATING FLANGE

The rotating-flange metal expansion joint is the type whose connection is made with a rotating flange. These components are generally installed on overhead pipe racks. They are widely used in hot water and steam applications, the chemical and pharmaceutical industries, the pulp and paper industry, as well as oil refineries.

In terms of performance characteristics, rotating-flange metal bellows axial expansion joints are highly preferred. Thanks to their excellent sealing performance and long, maintenance-free service life — resulting in lower investment costs — they can be installed on underground pipelines for safe transmission of steam and hot water. Rotating flanges also enable easy installation.

This group can be manufactured in stainless steel or carbon steel. They are produced as standard for 16 bar pressure, but production for higher pressures is also possible.

FIXED FLANGE

The fixed-flange metal expansion joint is the type with flanged connection. It is used when the pipeline where the product will be installed is flanged and offers significant convenience in terms of labor and installation time.

WELD-NECK METAL BELLOWS AXIAL EXPANSION JOINT

Weld-neck is another connection type of metal expansion joints. They are suitable for temperature ranges from -80°C up to +427°C, and optionally up to +1100°C.

WHAT IS THE PURPOSE OF A ROTATING-FLANGE METAL BELLOWS AXIAL EXPANSION JOINT?

Rotating-flange metal bellows axial expansion joints have a wide range of applications. They can be used to absorb axial expansion, reduce stress and noise in the system, and are suitable for all machines, motors, pumps, industrial applications, exhaust systems, gas and water lines, potable water networks, central heating systems and shipbuilding. For example, in hot oil applications, rotating-flange expansion joints with as few weld seams as possible should be selected.

HOW TO INSTALL A ROTATING-FLANGE AXIAL EXPANSION JOINT?

During installation, the opposite flange holes must be aligned with the bolt holes of the expansion joint flange. The expansion joint must never be twisted.
