Stainless steel bellows
Stainless steel bellows
Nominal diameter: DN15 ~ 4000mm
Nominal pressure: PN0.6 ~ 2.5MPa
Temperature: -40 ℃ ~ + 300 ℃
Main material: 304,316 L stainless steel, carbon
Medium: liquid, gas and other
Design criteria: GB / T12777-2008, GB / T14525-199
Working principle
Stainless steel corrugated pipe is used to take advantage of the bellows effective elastic deformation of the elastic deformation to absorb the pipeline, pipe or container by the thermal expansion and contraction and other reasons dimensional changes arising from a compensation device, belonging to a compensation element. Absorption of axial, lateral, and angular displacements.
Use
1, compensation absorption pipe axial, transverse, angular thermal deformation.
2, bellows expansion device to facilitate the installation and removal of the valve pipe.
3, absorbing equipment vibration, reduce the impact of equipment vibration on the pipeline.
4, to absorb the earthquake, subsidence of the pipe deformation.
Structural materials
1, bellows: stainless steel 304,316 L, 321, etc.
2, flange, take over: carbon steel, stainless steel 304,316 L, 321, etc.
3, rod bolts, nuts: carbon steel
Installation Precautions
1, the medium chloride ion content ≤ 25PPM.
2, welding slag splash bellows.
3, must follow the product flow signs installed.
4, both ends of the bellows must be properly set guide bearing and fixed bearing.
5, does not allow the deformation of corrugated compensator to forcefully adjust the installation of pipe position error.
6, Do not use the installation rod or limit rod lifting.
7, after the installation is complete, remove the transport rod and limit rod with a yellow mark.
