The expansion joint is a flexible part that can effectively compensate for axial displacement. In general, the expansion joint consists of a bellows, an end tube, a bracket, and a flange. In addition, expansion joints can be divided into two types, one is a metal expansion joint, and the other is a non-metallic expansion joint. In this article, I will introduce you to the precautions for installing the expansion joint.
As an elastic compensating element, the expansion joint has many advantages such as reliable operation, good performance, and compact structure. Expansion joints are widely used in chemical, nuclear and metallurgical industries. In terms of its shape, U-shaped expansion joints are the most widely used components. However, what should we pay attention to when installing the expansion joint?
1. Before installation, we should check the model and specifications of the expansion joint, and the bracket configuration of the pipeline should meet the design requirements.
2. For an expansion joint with an inner tube, we must make the inner tube direction and the medium flow direction consistent. In addition to this, the planar angular expansion joint should be consistent with the displacement plane.
3. For expansion joints that require cold tightening, the easily deformable auxiliary components should be removed after the pipe is installed.
4. In addition to pre-deformation and pre-stretching, it is strictly forbidden to adjust the displacement at the expense of the deformation of the expansion joint to prevent the normal function of the expansion joint, reduce the service life, and increase the load on the pipe and bracket configuration.
5. During the installation process, the welding slag is strictly prohibited from splashing onto the surface of the expansion joint to destroy the equipment.
6. Install the expansion joints according to the drawings made by the pipe and the installation instructions of the expansion joints.
7. After the installation is complete, remove the yellowed shipping fixing screw before the system is operational.
The above are the precautions for installing the expansion joint, including pre-installation, installation and post-installation precautions.
