Product Introduction
BELLOWS EXPANSION JOINT
Bellows expansion joint, also known as compensator or flexible joint, is made of high-performance flexible components designed to absorb thermal expansion, contraction, and mechanical displacement in industrial pipelines. Manufactured with precision-engineered metallic bellows (stainless steel, alloy steel), with its axial, lateral and angular compensation, expansion joint effectively mitigates pipeline stress, reduce noise, damp vibration transmitted from pumps, boilers and rotating equipment, etc. Therefore it helps maintain pipeline alignment, protect connected equipment, and extend overall system's service life. Compliant with international standards (ISO, DIN, ASME), our expansion joints are customized for diverse pressure, temperature, and displacement requirements.
Bellows material: SS304/SS321/SS316L/T1~T10/800/Hastelloy C276
Bellows type: round/oval/rectangular shaped, single-layer or multi-layer
Other parts material: Carbon steel, stainless steel, PTFE
End connection: flange, welded, clamp, thread (for small diameters)
Heat treatment: Solution annealing, Annealing, Stress relieving
Surface treatment: pickling & passivation, electropolishing, sandblasting, brushing/satin finish, mirror polish, hot-dip galvanizing, powder coating
