Rectangular metal expansion joint performance features: The material of rectangular metal bellows expansion joints is usually selected as carbon steel or stainless steel, featuring large cross-section, low pressure, high temperature, and optimized waveforms. They are mainly used for gas or dust-laden gas pipeline and fan outlet, designed to absorb displacement or reduce vibration.
Angle structure form: The application and working conditions will determine the correct structure and angle form of the rectangular metal expansion joint. Rectangular metal expansion joints with a V-shaped angle structure can be used under low-pressure environmental conditions. For high-pressure environments, a U-shaped structure is more suitable.
Rectangular metal expansion joint — Single oblique V-shaped structure:
This is a common and cost-effective structural design, suitable for thermal expansion and easily connected to pipelines via bolted or welded methods. It is an option for low cycle and vibration-free applications.]
Rectangular metal expansion joint — double bevel V-configuration
This triangular structure is slightly more expensive in production costs compared to the single-angled design. However, it offers a longer service life under the same operating conditions.
Rectangular metal expansion joint — Mirror finish V-type angle structure
This structural design is primarily used for low-pressure applications. Its features include a long service life and cost savings compared to a double-angled design.
Rectangular metal expansion joint — rounded U-shaped structure
When in use, consider this structure if the pressure reaches 2 bars and both vibration and cycle life are significant factors. The rounded structure expansion joint is expensive in terms of production costs.
