metal bellows
1.1) function :sensing pressure and outputting the axial displacement or angle displacement by stretching or contracting
1.2) material :
alloy: stannum and bronze QSn6.5-0.1, brass H80,
stainless steel: 1Cr18Ni9Ti, 1Cr18Ni9, 0Cr19Ni9.
1.3)specifications:
outside diameter from 8—120mm,
corrugation number and stiffness are from the fable A=(a/n)*N/mm,
A: bellows stiffness ,
a: one corrugation stiffness,
n: corrugation number
1.4) stiffness tolerance: greater precision :+/-10%
1.5)working temperature:
Bronze alloy QSn6.5-0.1: -60--+100 °C
Stainless steel 1Cr18Ni9Ti, 1Cr18Ni9, 0Cr19Ni9 : -194--+400 °C
1.6) working media :
Bronze alloy QSn6.5-0.1, H80 : atmosphere or fresh water
Stainless steel 1Cr18Ni9Ti, 1Cr18Ni9, 0Cr19Ni9: atmosphere ,fresh water ,nitric acid, phosphoric acid, sodium hydroxide
1.7)special requirement: designing and manufacturing metal bellows according to customer’s requirements.
