Unconstrained bellows compensator have achieved the final target of"non-restrictive"of pipe support spacing,which has been developed based on the singleaxial type, the duplex pul rod axial type and the duplex axial type with seats, which not only possesses the columnar stability but also has the self-guid-ing capacity lt is able to conquer errors with features such as small in volume, sare andreliable, able to eliminate common phenomena such as distorionand non-stability easily happened in axial type expansion joints in the past.
The unconstrained corrugated compensator in the corrugated pipe using single, double or multi-layer U-shaped wave, unconstrained compensator corrugated pipe and guide sleeve material for 1cr18ni9ti austenitic stainless steel, other materials for low carbon steel or low alloy steel.The unconstrained bellows compensator is exactly the same as the ordinary axial compensator in determining the distance between the fixed supports and calculating the thrust of the fixed supports.

Structural Characteristics of unconstrained bellows compensator(Bellows Expansion Joint):
Welded components:
One end of the directional protection tube is welded to the main directional plate.
The internal guide tube (enclosed within the directional protection tube) is welded to the secondary directional plate and the adjacent connecting pipe.
The positioning plate is welded to the directional protection tube.
This configuration provides robust support and directional stability, while the positioning plate prevents the bellows from flattening under tension.
Product feature：
1.The determination of the space between the fixed support and the calculation of the thrust of the fixed support of the unconstrained corrugated compensator are exactly the same as that of the ordinary axial compensator. In order to make the project stable and reliable, the unconstrained compensator is required to be installed near the fixed support, but also requires three guide supports within the distance between each fixed support.
2.The unconstrained bellows compensator can be applied to the overhead and trench laying of pipelines, or the directly buried laying with compensation. At this time, the inspection well or dark room should be set up where the unrestrained compensator is located.
3.unconstrained corrugated compensator used in pipeline axial compensation, compensation amount is large, with strong self-guiding and super bending ability, which can simplify the design of pipeline guide bracket, so that the guide bracket spacing installation can be adjusted.
