Bellows Basics
Bellows Material Types
Inconel 625 316L S/S Hastelloy C-276 Inconel 600 316 S/S Incoloy 825 Monel 400 304L S/S Incoloy 800/800H 321 S/S 304 S/S

Types of Movement Torsional Movement Angular Movement Lateral Movement Axial Movement

Cyclic Deflections & Cycle Life Cycle Test on a 12 " diameter A240-321SS Bellows with 8 convolutions. The bellows has met the EMJA cycle life calculation of 1,000 cycles and failed in the root of the convolutions at 1,285 cycles. Temperature Change Repetitive Mechanical Movements Vibrations Stresses

Expansion Joint Failure
Common Bellows Material Failures
Failure Mode Typical Source Stress Corrosion Chlorides (austenitic stainless steels) Caustics, High Temp. Sulfurous Gas (nickel alloys) Fatigue Vibration Carbide Precipitation Unstabilized Materials at High Temperatures Squirm & Rupture Over Pressurization * Squirm is the phenomena whereby the centerline of a straight bellows develops a sideways or lateral bow.

Accessories
Protective Covers & Internal Liners

Accessories
Purge Connector
Used for systems where sediments collect between outside of the internal liner and the inside of the bellows element
Injected clear gas or liquid periodically or continuously blows collected material out

Accessories
Limit Rods
