The important position of the deflector in the expansion joint1. Play a diversion role in the expansion joint, make the medium flowing in the expansion joint more stable, reduce structural vibration caused by the change of fluid flow characteristics when high-speed fluid flows through the bellows, a

1. Selection of corrugated expansion joint a. The corrugated expansion joint is only undergoes axial deformation, the stress on both ends is large, the middle part tends to deform to the side at any time. The compensation amount of each wave is generally only about 5-20mm, so the wave of the expans

Internal Liners in Expansion Joint Internal liners are recommended where the follwing conditions exist in a piping system:

TIPICAL CAUSES OF EXPANSION JOINT FAILURE Bellows expansion joints which have been properly designed and manufactured for specified piping system conditions have given many years of satisfactory service. Failures, of course,have occurred which are of concern both to users and to reputable expansi

Expansion Joint Glossary of Terms 1Fustar Bellows has adopted and encourages the use of the definitions of expansion joints and related equipment as published by The Expansion Joint Mnufactures Association. The definitions are taken,in part,from the Fifth Edition of the EJMA Standards. ANCHOR,DIRECT

EXPANSION JOINT INSTALLATION INSTRUCTIONS Metal Bellows Expansion Joints have been designed to absorb a specified amount of movement by flexing of the thingauge convolutions. If proper care is not taken during installation,it may reduce the cycle life and the pressure capacity of the expansion joint

Bellows Expansion Joint Torsional Deflection / Combined Deflections/ Cyclic Deflections Torsional Deflection Torsion refers to twisting one end of the bellows with respect to the other end, about the bellows centerline. Expansion joints are not normally expected to accept torsional deflection,

Expansion Joint Lateral Deflection & Angular Deflection Lateral Deflection Lateral refers to the direction perpendicular to the centerline of the expansion joint(in any plane). Other terms for this deflection are PARALLEL OFFSET and TRANSVERSE. This movement occurs with both of the ends of the expan
