The bellows in the unconstrained compensator are single-layer, double-layer or multi-layer U-shaped. The bellows and guide sleeves are made of 1Cr18Ni9Ti austenitic stainless steel and other materials are low carbon steel or low alloy steel. Unconstrained compensators are identical to conventional axial compensators in determining the distance between fixed supports and calculating the thrust of fixed supports. The unrestrained expansion joint also greatly loosened the installation requirements in addition to the cancellation of stretching work. Unrestrained expansion joints can be installed in the pipeline like a short tube, without the need to cut the length of the pipeline and expansion joints equal to the length of the pipeline after the entire line of steel pipes are joined as required by other axial expansion joints. It is also convenient for transportation, installation and thermal insulation due to unrestrained expansion and strong shell.
Performance characteristics
1. The determination of the distance between the fixed supports and the calculation of the thrust of the fixed supports of the unconstrained corrugated compensator are exactly the same as those of the conventional axial compensator. In order to make the project stable and reliable, the unconstrained compensator requires three guide brackets in each fixed bracket space besides the installation near the fixed bracket.
2. Unconstrained compensator can be used in overhead and trench laying of pipeline, and can also be used in direct buried laying with compensation. At this time, unconstrained compensator should be set up inspection well or darkroom.
3. Unconstrained corrugated compensator is used for axial compensation of pipeline. It has large compensation amount, strong self-steering and super bending resistance, so it can simplify the design of pipeline guide bracket, and make the distance between guide bracket can be adjusted arbitrarily.
