Metal Expansion Joint And Rubber Bellow Compensator
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.
Rubber Compensator
We can provide the most comprehensive selection of rubber expansion joints on the market, covering a wide range of applications and products of various sizes. By adopting the latest rubber and cord technology, we can provide the most effective solution to meet the performance requirements of any pipeline system. We can also develop special rubber expansion joints for special application installations.
Our rubber expansion joints can provide different standard flanges and different rubber properties. Therefore, the model and specification of rubber expansion joint shall be correctly selected according to the medium, pressure and temperature of each application.
It is composed of rubber and rubber-fiber fabric composite materials, steel flanges, sleeves, and thermal insulation materials. They are mainly used for pipes connection. The flexible connection between the pipes has the function of shock absorption, noise reduction, sealing, medium resistance, easy displacement and installation, and is an ideal accessory for shock absorption, noise reduction, smoke reduction and dust removal in the field of environmental protection.
