THESE ARE FLEXIBLE ELEMENTS THAT ARE USED TO ABSORB DIMENSIONAL CHANGES OR MOVEMENT ON THE PIPELINES DUE TO THERMAL EXPANSION OR MOVEMENT OF PRESSURE VESSEL OR TO ABSORB VIBRATION DUE TO EXHAUST APPLICATION. THESE EXPANSION JOINTS ARE ALSO FABRICATED AND MANUFACTURED FROM THICK GAUGE MATERIALS, WHICH ARE USED IN HEAT EXCHANGER OR PRESSURE VESSELS OR FOR SPECIAL APPLICATIONS. EXPANSION JOINTS ARE OF VARIOUS TYPES SUCH AS AXIAL TYPE, DOUBLE UNIVERSAL TYPE, TIED LATERAL TYPE AND GIMBAL TYPE ETC. THE EXPANSION JOINTS ARE DESIGNED TO ABSORB AXIAL, LATERAL AND ANGULAR MOVEMENTS.THESE ARE ALSO USED FOR ISOLATION OF VIBRATION, VALVE SEALING AND INSTRUMENTATION. THE STANDARD RANGE OF EXPANSION JOINTS OR BELLOWS IS MADE OUT OF STAINLESS STEEL AISI 304 GRADES. HOWEVER THESE CAN ALSO BE MADE OF STAINLESS STEEL AISI 321, 316 TO MEET THE NEED OF HIGH PRESSURE AND HIGH TEMPERATURE. NORMAL SIZE RANGE AVAILABLE IS FROM 80 MM DIAMETER TO 1000 MM DIAMETER AND 3000 MM SIZES ARE MANUFACTURED ON SPECIFIC REQUIREMENT.
Such Expansion joints are exposed to high tempreature and high movements observed in kiln of cement manufacturing plants. We design (As per EJMA) and manufacture such Expansion Joints along with necessary factory lining and end fittings. This Bellows are manufactured by SS 321, 316 or 316L material with more than one ply to resist the inner tempreature from kiln line. Such Bellows needs Inner Slee
