Anti‑Corrosion Noise‑Suppressing Steel Expansion Bellows for Metallurgical Processing
Product Description


1. High temperature and high pressure resistance: This is the most significant advantage compared to rubber expansion joints. It can operate in temperatures of several hundred degrees or even thousands of degrees (with insulation layer) and under pressures of several megapascals.
2. Corrosion resistance: The main material is usually stainless steel (such as 304, 316L) or other corrosion-resistant alloys, which can adapt to various harsh chemical media.
3. High reliability and long service life: With correct selection and installation, it has a very long fatigue life (i.e., the number of displacement cycles it can withstand).
4. Wide application range: It can be used from ultra-low temperature liquid hydrogen and liquid oxygen to high-temperature flue gas and hot air, from high vacuum to high-pressure conditions.
Core Functions and Roles

1. Compensation of Displacement - Core Function
(1) Axial Displacement: Absorbing compression or tension along the pipeline axis.
(3) Angular Displacement: Compensating for angular deviation at the pipeline connection.
(4) Combined Displacement: Absorbing two or three of the above displacements simultaneously.
It can effectively address the dimensional changes of the pipeline caused by thermal expansion and contraction, equipment vibration, foundation settlement or installation errors, release stress, and prevent damage to the pipeline, supports, or equipment.
2. Vibration and Noise Reduction
The metal corrugated pipe has good elasticity and can isolate and absorb mechanical vibrations and fluid pulsations generated by equipment such as fans, pumps, and compressors, reducing system noise.
3. Sealing
Provides a leak-free flexible connection, which is particularly crucial when transporting flammable, explosive, toxic, or expensive media.
1. Thermal pipeline network: Regional heating pipelines, pipelines for absorbing steam or hot water with thermal displacement.
2. Petrochemical industry: Process pipelines in refineries and chemical plants, catalytic cracking units.
3. Electric power industry: Flue gas and air ducts of power plant boilers, steam-water pipelines.
4. Metallurgical industry: Air supply systems and flue gas systems of blast furnaces, hot blast stoves, and converters.
5. Aerospace: Engine pipeline systems.
6. Shipbuilding: Engine exhaust systems, various ship pipelines.
