Metal expansion joint

Metal expansion joint

Metal expansion joints are critical components in pipeline systems for compensating thermal expansion and contraction, and absorbing vibrations. Made of corrosion-resistant metal materials (such as 304, 316 stainless steel), they are formed by combining corrugated tubes, flanges, or branch pipes. The corrugated tube design utilizes the elastic deformation of its folded structure to compensate for pipeline displacement in axial, transverse, or angular directions, alleviating stress in the system caused by temperature changes or equipment vibrations, thereby preventing pipeline rupture or joint leaks.   The product has strong pressure-bearing capacity and a wide temperature range (-270℃ to 1200℃), suitable for various medium conditions. It is widely used in industries such as petrochemical, power, and metallurgy. Installation is convenient, and dimensions and compensation amounts can be customized according to pipeline parameters, effectively ensuring the safe and stable operation of pipeline systems and extending equipment service life.
