Heat-insulation Corrosion-resistance Bidirectional Directly Buried External Pressure Type

Products


	[Structural Features] The product consists of working bellows, protection bellows, heat-insulation materials and movable covers. Axial movements of thermal pipelines created by temperature difference can be compensated by bellows axial expansion. Protection bellows and other components protect working bellows from erosion of harsh surroundings and extend service life of the product greatly. This type of expansion joints can be buried directly against the erosion of soil and underground water and compensation of movements is quite a lot.

	Material of Bellows: SUS 304(SUS 321 and SUS316L are also available) Nominal Diameter: DN150-DN1200 Working Pressure: PN2.5/6/10/16/25 Working Temperature: -80℃/+450℃ Connection: 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.
