JXF Flexible Dirt Filtration Expansion Joint

JXF Flexible Dirt Filtration Expansion Joint

Expansion joint is pumps, valves, pipes and other devices connected to the pipeline of new products, connected by the bolt, to make it as a whole, and has certain displacement, so you can at the time of installation and maintenance, according to the on-site installation size adjustment, at work, can put the axial thrust and also to the whole pipeline system.This not only improve work efficiency, and cut the pump, valve and other pipeline equipment to play a certain protective role.

Products Details

JXF Flexible Dirt Filtration Expansion Joint

Purpose of expansion joint:Expansion joints are mainly used to ensure the safe operation of pipelines and have the following functions: to compensate the axial, transverse and angular thermal deformation of absorption pipelines;Absorbing the vibration of equipment to reduce the influence of equipment vibration on the pipeline;Absorb the deformation of pipeline caused by earthquake and sinkhole.This product provides great convenience for installation, disassembly and replacement of various water supply and drainage pipelines, water towers, water pumps, water meters and valves, and plays a good regulating role for long-distance pipelines due to temperature difference.

The ripple compensator belongs to a compensation element.The effective expansion and deformation of the bellows of the working body is used to absorb the size changes caused by thermal expansion and cold contraction of pipelines, conduits and containers, etc., or to compensate the axial, transverse and angular displacements of pipelines, conduits and containers.It can also be used to reduce noise and vibration.It is widely used in modern industry.

Flexuble Dual Spherical Rubber Joint
KXT-S Flexible Dual Spherical Rubber Joint

XUVALdouble sphere rubber expansion joints are designed for piping systems to absorb pipe movements, relieve stress, reduce system noise/vibration, compensate for misalignment/offset and to protect rotating mechanical equipment against start-up surge forces. XUVAL double sphere rubber expansion joints are inherently stronger than the conventional hand-built style spool arch type. Internal pressure within a “sphere” is exerted in all directions, distributing forces evenly over a larger area. The spherical design “flowing arch” reduces turbulence and sediment buildup. Features and Benefits: Absorbs Directional Movement Thermal movements appear in any rigid pipe system due to temperature changes. XUVALdouble sphere rubber expansion joints  allow for axial compression or axial extension, lateral deflection as well as angular movement.
