Flange Bellows SS316 High Resistance Ptfe Lined Flexible Expansion Joint
Flange Bellows are precision-engineered flexible pressure components with integral flange connections, core structure is the corrugated metal bellows (usually stainless steel), combined with flanges at both ends for direct bolted installation to piping or equipment. Primarily designed to absorb axial, lateral and angular misalignment in piping systems, as well as compensate thermal expansion and contraction caused by temperature fluctuations, while dampening vibration and reducing mechanical stress on pipelines, valves and heat exchange equipment. Featuring excellent sealing performance, high pressure and temperature resistance, corrosion resistance and structural stability, they are widely used in petrochemical, power, metallurgy, HVAC and industrial process piping systems, especially suitable for harsh working conditions requiring reliable connection and flexible compensation.
Ptfe Lined Flexible Expansion Joint have the following characteristics:
Taking into account the advantages of this product, its service life greatly exceeds that of existing steam hoses. Long term use does not require replacement, greatly reducing usage costs, improving efficiency, and being economical and practical.
