Flange Type Expansion Joint
Flange Type Expansion Joint is able to withstand the expansion and shortening of piping system due to temperature change and medium flow. It consists of inner expansion element, outer protective shell and flange connection part, with certain elasticity and displacement ability, which can effectively reduce the stress and deformation of pipeline and equipment due to temperature and pressure changes, and ensure the safe and stable operation of pipeline system.
Overview
Suggestion:
1. Select the appropriate type and specification of expansion joints. Different types and specifications of expansion joints are suitable for different working conditions and media, need to be selected according to the actual situation.
2. Check whether the expansion joint and its related parts are intact and undamaged before installation, and replace or replenish them in time if any damage or missing parts are found.
3. The installation should be checked and adjusted carefully according to the requirements to ensure that the installation position and connection of expansion joints are correct and reliable.
4. Pay attention to regular inspection and maintenance in use, clean the internal impurities and dirt in time to ensure the normal working condition of the expansion joint.
5. It is strictly prohibited to add other fasteners or pressure equipment in the flange connection part of the expansion joint, so as not to affect the normal work and safe and stable operation of the expansion joint.
