㉿Mark inscription allowed product/ Korea register of ahipping model approval
 

This is used to absorb the axialdirection expansion and contraction of a pipeline that occurs according to temperature changes. Since it is an internal pressure type, it is buckling-free and ensures smooth expansion/contraction.

Features

• Absorb the expansion & contraction of pipelines by temperature changes.
• Outstanding level of corrosion resistance : Parts materials come into contact with fluid are made of stainless steel.
• Outer tube has been used to prevent damage to the bellows from impact
