Metal compensator must pay attention to the welding work during the installation process. Do not allow welding slag to splash onto the bellows surface and cause other mechanical damage to the bellows. After welding is completed, the welded area should be de-rusted. Generally tap the welded area with an iron bar until the metal luster is revealed. When checking, if there is no leakage and false welding, it is regarded as meeting the construction standard. It is important to note that expansion joints do not absorb torque, so they are not allowed to be twisted when they are installed. The pipeline equipped with expansion joints should be opened and closed gradually during the operation of the valve to avoid sudden changes in temperature and pressure in the pipeline, which may cause damage to the bracket or expansion joint.
