HOSE TERMINOLOGY Annular – A Hose profile that is designed so each convolution is a separate circle or ring. Braid – Woven wire cover placed over hose which prevents elongation of the hose and permits higher working pressure. Close Pitch- More corrugations per foot which renders the longest f

Bellows Expansion Joint Styles Axial Joint Axial bellows expansion joints are designed to accommodate compressive or extension movements along the bellows longitudinals axis.Movements available can be specified as amounts from a “neutral length”.The neutral length is the theoretical length before mo

Assembly Installation Fustar Corrugated hose is engineered to provide maximum service life when properly installed. Improper installation,incorrect flexing or careless handling in an application will reduce the effective service life of the hose and cause premature failure of assembly. The following

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

Bellows Type Deflections --- Axial Deflection In order to properly apply expansion joints to piping systems, it is necessary that both the piping specialist and the expansion joint designer each understand not only how the piping flexes, but how the various expansion joint types function and what

Bellows DesignThe bellows is the flexible element of expansion joint.It must be strong enough circumferentially to withstand the pressure and flexible enough longitudinally to accept the deflections for which it was designed , and as repetitively as necessary with a minimum resistance. This strength
