Bis Certification For Steel pipe flanges Steel pipe flanges are critical components used to connect, terminate, or modify flow in piping systems. Bureau of Indian Standards (BIS) mandates manufacturers to obtain BIS license under IS 6392:2020 for these flanges. This standard ensures that flanges meet stringent quality, safety and performance criteria, including precise dimensions, material specifications and pressure ratings. IS 6392:2020 compliance guarantees reliability and interoperability across various industrial applications such as oil and gas, chemicals and water treatment. Obtaining a BIS license symbolizes adherence to high manufacturing standards, promoting confidence and safety in the piping infrastructure.
