Product Description
Our rectangular metal bellows expansion joints, designed with optimized American EJMA standards, are produced to meet various material, wave pattern, and structural requirements as specified by customers. They feature excellent flexibility, corrosion resistance, high-temperature tolerance, and long fatigue life. Having supplied to both domestic and international clients for many years, our product quality remains stable and reliable.Primarily used for gas turbine exhaust systems, turbine or condenser connections, hot water heater exhaust outlets, pressure ventilation fan seals, exhaust gas ducts, AC heat exchangers, sedimentation tanks, and other steam and large pipeline systems. Gas or dust-laden gas conveying pipes and fan outlets for absorbing displacement or vibration reduction.
Rectangular metal corrugated expansion joint performance features:Rectangular metal bellows expansion joints are typically made of Corten steel or stainless steel, characterized by large cross-sections, low pressure, high temperatures, and optimized wave patterns. They are mainly used in gas or dusty gas pipeline transmission and fan outlets, designed to absorb displacement or reduce vibration.
Rectangular metal corrugated pipe expansion joint angular structure form:The application and working conditions will determine the structure of the correct rectangular metal expansion joint and the form of its angles. A rectangular metal expansion joint with a V-shaped angle structure can be used under low-pressure environmental conditions. Under high-pressure conditions, a U-shaped structure is more suitable.
Rectangular metal corrugated pipe expansion joints application scope:
Rectangular metal expansion joints for gas turbine exhaust systems, connections for turbines or condensers, exhaust outlets for water heaters, sealing for pressure ventilation fans, exhaust gas pipelines, AC heat exchangers, sedimentation tanks, and other steam and large pipeline systems.
Design Considerations for Rectangular Metal Bellows Expansion Joints:
Axial displacement of expansion joints is crucial to indicate the direction of displacement applied to them, especially on large rectangular pipelines. When lateral displacement is applied to "critical areas," it should be accompanied by an equal amount of axial displacement, which is much more effective than applying lateral displacement only to "non-critical areas." In many cases, a longer, compound rectangular metal expansion joint is the practical solution. The range of raw material options for rectangular metal expansion joints is very wide, including 300 series austenitic stainless steel and high-nickel alloys.
