Flanges dimensions

Diameters and bolt circles for standard ASME B16. What is the size of a flange? The following charts are for reference use only. RTJ flanges dimensions are covered in ASME B16. Pipe Flanges and Flanged Fittings for size NPS ½” to 24” for above NPS 26” to 60” it should be as per ASME B16.

During dimensional inspection of flange, you should check for.

Slip on flange dimensions are covered in ASME B16. This dimension is commonly associated with “true” lap joints. Industry standard is to make to the slip on length through the hub. Not only does Texas Flange offer carbon steel pipe flanges and flanged fittings, but we also supply stainless steel flanges that are used for a wide range of projects. Weld neck flange dimensions are covered in ASME B16.

Plate flanges can be ordered both for waterworks and petrochemical applications. Bar flanges and Forged Spec flanges can also be made per the dimensions in our catalog. The charts show the dimensions of ASME B16.

If possible also medium, pressure and temperature. Dimensions are in inches. Standard bore dimensions provided. See bore chart for other wall thicknesses. Class 6Slip-On Flanges.

Flat face option available. Socket weld flange dimensions are covered in ASME B16. All dimensions are in inches. Since the inner diameter of the flange is slightly larger than the outer diameter of the pipe, the SO flange can be directly connected to equipment or pipe by fillet weld at the top and bottom of the flange.

Lengths of alloy steel stud bolts do not include the height of the points. Bolt lengths not shown in the tables can be determined by reference to Appendix F of ANSI 916. A flange manufactured to meet ANSI standards (USA) for size, pressure ratings and temperature ratings.

We offer high quality ANSI standards flanges that are dimensionally accurate and highly resistant to corrosion. These slip on can sometimes have a boss or hub, and can be made with a bore to suit either pipe or tube. All lengths are calculated with a gasket thickness of mm. The dimensions of the bolts are calculated for the type weld neck flange.

Other types of flanges can be have different bolt hole diameters and thicknesses, so that the bolts even can have different dimensions. Limitation of Liability and Disclaimer.

K mm Hole H mm Bolts No. Carbon steel flanges mechanical properties and chemistry conform to ASTM A105. Flanges are furnished face drilled and spot faced or back faced.
