Rectangular metal expansion joints are commonly used for rectangular ducting applications in power generation and industrial industries KE-Burgmann designs rectangular metal expansion joints inhouse, using a unique, dynamic computer software, based on and continuously updated with the results obtained from testing programs

Rectangular design parameters:

• Pressure capability
• Instability
• Stresses due to deflection
• Fatigue life
• Spring rate and forces

Determination of a design is affected by other variables:

• diameter
• materials
• material availability
• convolution form (pitch, depth, number of ply, thickness of ply)
• manufacturing capability

Important considerations before installation of rectangular expansion joints:

• improved plant efficiency
• reduced plant size
• ease of assembly
• ease of and trouble-free operation
• safety
