Metal Bellows Benefits
Multi-Ply , Multi Wall Laminated Metal Bellows Benefits

The most important feature of FLEXPERT Metal Bellows Expansion joints is the multi-ply/multi-wall laminated bellows structure of the metal bellows elements. The metal bellows are manufactured from multi-wall laminated tube of plies ranging in number from 2 to 20 depending up on diameter and specified operating pressure and other design parameters.

Each of the thin layer acts as a nearly neutral fiber which offer significantly lower resistance to movements in the piping system than a single wall metal bellows. Significantly less force is required for actuating the laminated bellows.

Multi-Ply , Multi Wall Laminated Metal Bellows Benefits

Thus with the same dimensions FLEXPERT multi-wall bellows can accept significantly more movements with ease. The stresses induced on the individual layers of FLEXPERT multi-wall bellows are a fraction of the stresses induced in the single wall bellows of equal thickness. This results in highest possible service life of the FLEXPERT laminated bellows.

  • Increasing Flexibility & Reducing Deflection Forces.
  • Higher Pressures & Lower Thrust Forces
  • Lower Spring Rates & Higher Elasticity.
  • Minimal Installation length due to high Elasticity.
  • Fail safe design due to Multi-Wall Bellows Unit
  • High corrosion resistance can be attained economically for Laminated Bellows.

Design and Manufacturing

We design and manufacture single as well as multi-ply metal bellows.The bellows is the basic element of an expansion joint and the following characteristics are given special attention during the bellows design process.

Flexibility
Thin gauge material is used in the manufacture of multi-ply bellows giving enhanced flexibility coupled with lower deflection forces.
world class Expansion Bellows
Maximum Travel
Maximum axial, lateral and angular movements are optimized considering the lowest possible spring rates and shortest overall length.

axial expansion joints
Fail-Safe Design
Bellows are designed for safety . In case system fail or occurrence of excessive operation conditions.
Expansion Joints – Designed to Withstand Extreme Pressure
Cycle Life
The contour of the thin gauge multi-ply convolution is designed to minimize pressure and deflection induced stresses . Full load thermal cycles are evaluated with relation to total travel.
