Overview
Metal Expansion Joint

Metal expansion joint is a kind of compensator made of metal like stainless steel 316L and 254 etc. It can expand and contract along the axis of the pipeline, and also allows a small amount of bending. Axial bellows expansion joints are used on pipelines for axial length compensation. In order to prevent exceeding the allowable compensation amount, protective pull rods or protective rings are arranged at both ends of the corrugated pipe, and guide brackets are arranged on the two ends of the pipe connected to it. In addition, there are corner and lateral expansion joints, which can be used to compensate for the corner and lateral deformation of the pipeline. The advantage of this type of expansion joint is to save space, save materials, and facilitate standardization and mass production.
Our products are widely applied on the EGCS system, 254 material is highly recommended as good corrosion resistant performance in acid environment. Thanks to the good process and quality control, our products are much durable and gain a lot of favorable comments from shipowners and shipyards.
