Characteristics of the Unconstrained Corrugated Expansion Joint
The determination of the distance between the fixed brackets and the calculation of the fixed support thrust of the Unconstrained Corrugated Expansion Joint are exactly the same as those of the ordinary axial type compensator. In order to make the project stable and reliable, in addition to being installed close to the fixed bracket, the unconstrained corrugated expansion joint also requires three guide brackets within the distance between each fixed bracket.
Unconstrained compensators can be used for overhead and trench laying of pipelines, and can also be used for compensated direct buried laying. In this case, an inspection well or dark room should be installed at the unconstrained compensator.
Unconstrained corrugated expansion joints are used for axial compensation of pipelines. They have large compensation amounts, strong self-guiding and super bending resistance, which can simplify the design of pipeline guide brackets and ensure even spacing between guide brackets. Can be adjusted at will.
