ANSI 150LB Stainless Steel Metal Exhaust Compensator Reinforced Metal Bellows Expansion Joint
Product Introduction
A bellows is a tubular structure with a corrugated shape, usually made of metal.It has high flexibility and elasticity, and can withstand large pressure and deformation. Bellows are widely used in various fields.
Benefits
1. Low stiffness and small elastic axial force
2. The operating temperature range is high and the corrosion
resistance is good
3. It can reasonably prevent shocks and reduce noise
4. Able to compensate for multi-dimensional orientation. Various
forms, large compensation amount, long service life
5. Be able to reasonably compensate or eliminate installation
deviations
Product features
1. Absorption of thermal expansion and cold contraction: Compensate for the change in pipe size caused by temperature
changes, that is, thermal expansion and cold contraction, thereby
reducing the stress concentration and potential damage in the
pipeline system.
2. Compensate for displacement: It can not only compensate for the axial displacement of the
pipeline, but also for the lateral and angular displacement, which
may be caused by factors such as pipeline installation error,
mechanical vibration or earthquake.
3. Vibration and noise reduction: The flexible structure of the corrugated compensator helps to
absorb and isolate vibration, reduce the impact of vibration on the
piping system and surrounding equipment, and also reduce the noise
level during operation.
