Products


	[Structural Features] This type of expansion joints consists of one bellow which is used to carry the external pressure , one sleeve, two end rings and some other components. The expansion joints, with good self-conductance, is widely used in heat supply network. It can absorb most axial movements but do not carry the thrust created by the bellow’s pressurization.

	Material of Bellows: SUS 304(SUS 321 and SUS316L are also available) Nominal Diameter: DN65-DN1200 Working Pressure: PN2.5/6/10/16/25 Working Temperature: -80℃/+450℃ Connection: Flanged connections or pipe end connection Material of Connection: Carbon steel GB/T 700 for standard use(Special material of connection to meet specific customer & industry requirements) Other choices: Inner sleeve, carbon steel, SUS304(SUS 321 and SUS316L are also available) Notes: If you have any other requirement, please contact us
