The American Standard flanges manufactured by our factory strictly comply with the international standard ASME/ANSI B16.5. They cover a wide range of high-quality materials including carbon steel (Q235B, A105) and stainless steel (304, 316L, 321). Various types of flanges are available for customization, such as slip-on flanges, weld neck flanges, blind flanges and socket weld flanges. With sizes ranging from 1/2" to 48" and pressure classes from 150LB to 2500LB, our products fully meet the requirements of different industrial scenarios.
Adopting advanced forging technology and precision machining processes, the flange blanks undergo normalization and tempering after high-temperature forging, which effectively enhances the toughness and strength of the material and prevents defects like cracks and blowholes. The sealing surfaces of the flanges are precisely ground to meet the required roughness standards, ensuring excellent sealing performance. Our flanges can operate stably under harsh working conditions such as high temperature (-20℃ to 600℃), high pressure and strong corrosion, thus guaranteeing the sealing performance and safety of pipeline system connections.
