The rectangular metal bellows expansion joint adopts the optimized design of the American EJMA standard. Produce rectangular metal bellows expansion joints with different materials, waveforms, and structural forms according to customer requirements. It has the characteristics of good flexibility, corrosion resistance, high temperature resistance, and long fatigue life. We have been supplying to hundreds of customers both domestically and internationally for many years, with stable and reliable product quality. Mainly used 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, condensers, and other steam and large pipeline systems. Gas or dusty gas pipelines and fan outlets are used to absorb displacement or shock absorption.
Performance characteristics of rectangular metal corrugated pipe expansion joint: The material of rectangular metal corrugated pipe expansion joint is usually made of Corton steel or stainless steel, which is characterized by large cross-section, low pressure, high temperature, and optimized waveform. It is mainly used for conveying gas or dusty gas pipelines and fan outlets, and is used to absorb displacement or shock absorption.
Rectangular metal bellows expansion joint angle structure form: The correct structure and angle structure form of the rectangular metal expansion joint will be determined by its purpose and working conditions. Rectangular metal expansion joints with V-shaped corner structures can be used under low pressure environmental conditions. The most suitable application of U-shaped structure under high-pressure environmental conditions.
Application scope of rectangular metal bellows expansion joint:
Rectangular metal expansion joint gas turbine exhaust system, connection parts of turbine or condenser, exhaust port of water heater, sealing of pressure ventilation fan, exhaust gas discharge pipeline, AC heat exchanger, precipitator and other steam and large pipeline systems.
Design concept of rectangular metal corrugated pipe expansion joint:
It is very important to specify the axial displacement of the expansion joint to indicate the direction of displacement applied to the expansion joint, especially on large rectangular pipelines. When lateral displacement is applied to "critical areas", it needs to be matched with an equal amount of axial displacement, which is much better than simply applying lateral displacement to "non critical areas". In many instances, a longer composite rectangular metal expansion joint is the only practical solution. The range of raw material selection for rectangular metal expansion joints is very wide, including 300 series austenitic stainless steel and high nickel alloys.
