Why Choose Fulihua for JIS Flanges?
JIS flanges require specific dimensional compliance that differs meaningfully from ASME and EN standards — bolt circle diameter, flange thickness, and face dimensions all follow JIS-specific tables. Fulihua's engineering team is experienced in JIS B2220 dimensional requirements, and we maintain dedicated tooling and inspection gauges for JIS production. Material certificates per EN 10204 3.1/3.2, JIS-compliant marking, and third-party inspection are all available.
