2.5-Convolution Flexible Bellows

2.5-DN16-D25.4-H11.5，Capable of compensating for displacement within specified ranges axially, laterally, or angularly, absorbing deformation caused by thermal expansion/contraction and vibration in pipelines and equipment.

Description

Advantages of 2.5-Convolution Flexible Metal Bellows

(Short-wave / Limited convolution design)

High Pressure Resistance & Rigidity

Only 2.5 convolutions provide strong structural stiffness, supporting extremely high working pressure without instability or squirming.
Excellent Stability & No Deformation Risk

Short body, firm shape, anti-buckling, ideal for high-pressure pipeline critical sections.
Low Spring Rate / Compact Installation

Ultra-compact length, saves space, perfect for narrow flange-to-flange mounting.
Concentrated Strength & Safety

Stress is evenly controlled within few waves, high safety factor for heavy-duty industrial systems.
Precise Limited Displacement Compensation

Absorbs small axial / minor lateral movement, suitable for precise equipment with strict position tolerance.
Long Service Life under High Loads

Robust wave design resists fatigue under pressure pulsation and mechanical shock.
Zero Leakage & Heavy-Duty Sealing

All-metal welded construction for steam, oil, gas, hydraulic and vacuum high-pressure applications.

Simple Comparison (quick for your catalog)

2.5 Convolution: High pressure, rigid, compact, strong → Heavy duty / High pressure
28 Convolution: Super flexible, large displacement → Thermal expansion / Vibration absorption
