Metal Expansion Joint

Unrestrained assemblies and restrained assemblies.

Metal expansion joint.

Externally pressurized metal expansion joint external pressurization eliminates bellows squirm large axial movement maintenance free. The pressure load produced by internal pressure is contained by hinged parts and it is not necessary to install strong fix points and robust guiding in piping system. Due to this reason. The most common fitting configurations are flanges or beveled weld ends.

Metal expansion joint engineering. Hinged single expansion joint consists of metal bellows flanges or pipe ends and restraint system with axis of rotation. Hinged expansion joint can only accept angular movement. Senior flexonics engineers manufactures and markets metal expansion joints and is recognized as the leader in the expansion joint industry.

Expansion joints may contain one or more bellows and are frequently designed with anchors and pipe alignment guides to prevent bowing and buckling in a piping system. Keyser metal expansion joints design. Metragator metal expansion joint. The metal bellows element consists of a number of convolutions formed into the wall of a relatively thin gauge cylinder usually of stainless steel or other high nickel alloys.

In order to evaluate the loads upon piping supports or equipment the determination of the forces and movements required is essential in order to move an expansion joint. The tefbellows is an expansion joint that combines the properties of metal and ptfe into the most advanced expansion joint available for highly corrosive piping systems. Bellows not directly exposed to abrasive media heavy wall housing protects from external damage max working pressure. Normal design temperatures are from 300f to 400f and they will retain their pressure carrying capacity up to 1 200f in an upset condition sufficient time for system shut down and replacement.

Metal expansion joints fall into 2 different basic categories. Axial angular and lateral expansion joints. Hose master s in house product and failure analysis lab can identify various failure modes whether a result of fatigue corrosion deformation or from a host of other possible causes. A key to permanently solving any tough metal expansion joint application is to accurately identify the root cause s of past failure modes of products removed from service.

The in line pressure balanced metal bellows expansion joint is used in a straight piping run to absorb axial movement with minimal thrust forces imposed on the system anchors each in line pressure balanced expansion joint is designed for a specific pressure temperature and axial compression rating.
