ANSI ASA法兰 ANSI ASA Flanges – Non rotatable
MDC ASA-style flanges mate with standard 150 lb. ASA-ANSI flanges. Flanges are offered with choice of smooth face or O-ring groove. Eight flange sizes are detailed in this section. They are available blank or bored to fit tube sizes 1-1/2″ through 12″ O.D.
The vacuum seal is made by compressing an O-ring between a mating pair of flanges. The pair includes a smooth face flange and an O-ring grooved flange.

Flanges are fabricated from type 304 stainless steel with a surface finish of 32 micro-inches. All corners are chamfered 45°. Sealed flange assemblies are useable to 10-8 Torr and can be baked to 200°C. The maximum temperature for sustained use is 150°C.
Note that repeated bakeout to 200°C can cause deterioration of O-rings and require their periodic replacement.
Applications include use with various types of vacuum chambers, manifolds, furnaces, diffusion pump stations, valves, test equipment, pumps, special viewports, and a variety of experimental devices.
