How to Quickly Determine Which Expansion Joint You Need


Metal Expansion joint can be divided into axial expansion joints and lateral expansion joints.

Axial expansion joint is to do the best effective to absorb the expansion along the pipeline.Conversely, movement not along the pipe direction can be used by lateral expansion joints.

Can choose Non-welded,moreaffordable price EH-150SG
Small nominal bore, threaded type EH-250SG
Large nominal bore, flange type, can also meet small lateral displacement EH-400SG
Less expensive than EH-400SG if not strictly required EH-500HE
Greater axial displacement is required EH-700/700H
With External Cover for protection EH-1000/1000H
Lateral Greater movement EH-810/810H
Longer length EH-800/800H
Angular movement with External cover EH-900/900H

The principle is the expansion and contraction of the pipeline caused by the temperature change of thermal expansion and cold contraction.When the temperature difference becomes larger and the pipeline is heated and expanded, the expansion joint will be squeezed and compressed by the pipeline. On the contrary, the pipeline will contract when it is cold, and the expansion joint will be stretched due to the contraction of the pipeline.

Therefore, if you want to purchase, please first determine whether you need the expansion joint, determine whether you use the axial or horizontal displacement, and then determine the specific one according to your other requirements, so that customers can select the type more quickly and efficiently even if you don’t know this.
