Feature: Long-neck flanges are typically made of heat-resistant materials (e.g., carbon steel ASTM A105, stainless steel 316L) and their integrated structure maintains stability at high temperatures (up to 600°C for some materials). The neck design also helps dissipate partial heat, reducing thermal deformation.
Application: Essential in high-temperature boiler systems (e.g., power plant steam boilers). The flanges connect the boiler’s steam outlet to pipelines, withstanding long-term high-temperature steam (around 300-450°C) without losing structural integrity or sealing.
