The transverse expansion joint of the small pull rod is composed of two bellows, an intermediate nozzle and a small pull rod with a limiting nut.
There are two ways to connect the transverse expansion joints and the pipes of flanges: flange connection and welding.
In addition to compensating the lateral displacement and angular displacement of the curved pipe, the transverse expansion joint can also compensate for the axial displacement. The axial compensation and the lateral compensation (X0, Y0) in the sample are used separately as the maximum value of axial compensation or lateral compensation. This case should satisfy the following relation, respectively:
X1 < Xo Y1 < Yo
The actual values of X1 and Y1 are used individually for axial compensation or lateral compensation.
When the compensator has axial displacement and lateral displacement simultaneously, the selection of the two compensation quantities (X1, Y1) should satisfy the following formula:
At this point, X1 and Y1 are the actual values of axial displacement and lateral displacement at the same time.
The resultant displacement can be compensated in axial, angular, transverse and all directions. The small pull rod can not bear the internal pressure thrust.
The transverse expansion joint of a small pull rod is composed of two bellows, which are connected by the middle pipe, and the structure parts such as pull rod, end plate and spherical and conical washer. The bellows are made of 1Cr18Ni9Ti or SUS304 material, while absorbing the lateral displacement, the axial displacement is also absorbed.
