Expansion Joint will be effective with Building construcsion faces, concrete slabs, and pipelines expand and contract due to warming and cooling from seasonal variation, or due to other heat sources. Before expansion joint gaps were built into these structures, they would crack under the stress induced. Other types of expansion joints can include: fabric expansion joint, metal expansion joints, rubber expansion joint, etc. NFA Fabric Expansion Joints is flexible connectors designed to provide stress relief in ducting systems by absorbing movement caused by thermal changes. They also act as vibration isolators, shock absorbers and in some instances, make up for minor misalignment of at joining ducting or equipment. NFA Metal Expansion Joints are flexible connections, installed in piping and ducting systems to accommodate expansion and vibration caused by changes in temperature, pressure and/or media. NFA Rubber Expansion Joints are used to provide relief from stresses caused by thermal movement and mechanical activity in piping and ducting system. The other main job is to reduce noise, isolate vibration, compensate for misalignment and prolong the life of notive equipment. They are also provide excellent resistance to shock and wear.
