Customized Flexible Stainless Steel Exhaust Duct Compensator Bellows Metal Expansion Joint
The stainless steel bellows expansion joint consists of a bellows and two ends of the pipe.
The axial displacement of the pipeline is absorbed by the flexible deformation of the stainless steel bellows compensator, and the two ends of the pipe are connected to the pipeline.
The stainless steel bellows compensator is also called an expansion joint in customary manner; the connection methods are divided into flange connection and welding.

Bellow expansion Joint core features and advantages
High pressure resistance: The multi-layer structure can withstand higher pressure (up to tens of MPa) and is suitable for high-pressure environments.
Long life: The welding process reduces material fatigue and the number of dynamic cycles can reach more than one million times.
High-precision compensation: Strong axial, lateral and angular displacement compensation capabilities, suitable for complex working conditions.
Good sealing: The fully welded structure has no leakage risk and is suitable for high vacuum or corrosive media.
Wide temperature range: Depending on the material, the operating temperature can cover -200°C to +800°C.
Metal Bellows Expansion Joints Main application areas
Industrial valves: as valve stem sealing elements to prevent medium leakage (such as high temperature and high pressure valves).
Aerospace: pressure compensation and shock absorption of fuel systems and hydraulic systems.
Petrochemical and nuclear power: thermal expansion compensation and sealing of pumps and reactors.
Vacuum equipment: vacuum sealing of semiconductor manufacturing and vacuum furnaces.
Automotive industry: thermal displacement compensation of turbochargers and exhaust systems.
