Metal corrugated compensator pipe fittings role

Metal corrugated compensator pipe fittings role
Metal corrugated compensator in metal corrugated compensator, one is spiral corrugated pipe, and the other is annular corrugated compensator. Spiral metal corrugated pipe is a spiral arrangement of pipe shell, there is a spiral ascending angle between two adjacent corrugations, all the corrugations can be connected by spiral line. Absorb earthquake . Deformation of the pipe by ground subsidence. Absorb equipment vibration and reduce the impact of equipment vibration on the pipe. Compensation absorber pipe axial. Transverse. Angular thermal deformation.
Corrugated compensator performance tests include: stiffness test, stability test, fatigue test, yield rupture test, vibration test, impact test, high temperature fatigue test, etc.
① stiffness test: the axial stiffness, transverse stiffness, bending stiffness measurement methods and boundary conditions are required, and the number of tests and data processing methods are given.
② fatigue test: the axial type, straight pipe pressure balance type, hinge type, pull the type and other structural forms of compensators simulate the actual deformation conditions of the fatigue test, the test method and determination criteria.
③ vibration test: the vibration test vibration form, frequency range, vibration acceleration, the requirements of the scanning time of each frequency band is given.
④ Impact test: the impact acceleration, pulse duration, the number of impact effects and the boundary conditions of the impact test are specified.
