Rectangular Metallic Pipe Expansion Joints

Rectangular Metallic Pipe Expansion Joints Introduction

‌Rectangular metal expansion joint‌ is a widely used device in industrial piping systems. Its main functions include compensating for the axial, lateral and angular thermal deformation of the pipeline, absorbing equipment vibration, reducing the impact of vibration on the pipeline, and absorbing the deformation of the pipeline caused by external forces such as earthquakes and ground subsidence. The material of the rectangular metal expansion joint is usually Corten steel or stainless steel, which has the characteristics of large cross-section, low pressure,high temperature and optimized waveform. It is mainly used for conveying gas or dusty gas pipelines and fan outlets to absorb displacement or shock absorption. This expansion joint has good flexibility, corrosion resistance, high temperature resistance and long fatigue life. Therefore, it is suitable for gas turbine exhaust systems, connection parts of turbines or condensers, exhaust ports of water heaters, sealing of pressure ventilation fans, exhaust gas discharge pipelines, AC heat exchangers, precipitators and other steam and large pipeline systems.

The connection methods of rectangular metal expansion joints are mainly welding and flange connection. If it is a flange connection,the flange connection size of the other party needs to be provided. This expansion joint is generally large in shape, so it cannot withstand too much pressure and is usually used in duct systems. Its application industries include steel, electricity, petrochemical, cement, etc. With the progress of society and the improvement of environmental awareness, the application of rectangular metal expansion joints in various pipelines is becoming more and more extensive.
