Dimensions are in inches. Weights are in pounds.
Note:
Sizes are nominal inside diameters of pipe or shell used with Welding Neck flanges, and nominal OD of pipe or shell used with Slip-On flanges. Larger sizes, as well as intermediate sizes, can be furnished.
Bolt lengths are calculated based on bolting on slip-on to one blind. Any other bolting combination will cause variance in bolt length.
Bolt hole diameter 1/8in. larger than bolt diameter
