The introduction of internal pressure type bellows
Internal pressure type bellows is medium in the corrugated tube, on the basis of compressed corrugated absorption pipeline thermal expansion, need according to the environmental temperature pre-stretching before installation.
Within the inner pressure type bellows including axial pressure type bellows, buried inside pressure type bellows, material for 304.
In the axial pressure type corrugated pipe is mainly used to compensate the axial displacement, also can compensate the axial and lateral horizontal displacement or synthetic displacement, have the ability to compensate for angular displacement, angular displacement but usually don't apply it compensation. This kind of corrugated pipe has simple structure, low price, thus preferable.
Directly buried inside pressure type corrugated pipe is mainly used for buried pipeline axial compensation, at the same time it has strong bending capacity, so don't consider the effect of pipe sinking, buried type wave ?
