Flange by Pressure Class

Flanges are normally manufactured in seven basic ratings according to ASME B16.5: 150 Lb, 300 Lb, 400 Lb, 600 Lb, 900 Lb, 1500 Lb and 2500 Lb, we can manufacture all pressure class flanges as per customer drawing in ASTM / ASME / ANSI / JIS standards.

The number and diameters (mm) of the bolt holes are:
Class 150 - 12 x 25.4, | Class 300 - 16 x 28.6, | Class 400 - 16 x 34.9, | Class 600 - 20 x 34.9, | Class 900 - 20 x 38.1, | Class 1500 - 16 x 54, | Class 2500 - 12 x 73
