The Flexpert Bellow type Dismantling Joints are designed to enable mounting and dismantling of valves from pipelines. They are double flanged fittings that can accept up to 100mm (4″) of longitudinal adjustment, with the tie bars supplied to lock at the desired length. In addition the bellow dismantling joints provide compression for joints to facilitate installation and dismantling procedures, the bellow compensates for axial movements of the pipe.
The standard longitudinal adjustability of ±25mm makes it the ideal solution for all standard and non-standard applications, and these dismantling joint bellows offer perfect support when installing and removing valves by compressing the expansion joint in the moment of fitting or removing. To assist in the absorption of pressure thrust forces brought about by the internal pressure of pipelines, restrain screws are provided for the highly rigid flanged equipment.
Various Types of Bellow Dismantling Joints
The range of dismantling joints is available both with flanged and welded terminals and with a diameter from DN 40 to DN 3500, and rated pressure from PN 2.5 to PN 64. Although larger sizes and custom made Dismantling Joints can be designed and built on request.
You can choose from several versions of the dismantling joints such as: AISI 316L metal AISI304, 316, 316L Stainless steel flanges with special coating cycles. Custom tie rods that fit the flange profile.
We provide great, on time services to our valuable customers.
