Understand Dimensions of Stainless Steel 316 1500 Class Flange Dimensions To Simple diagram

Naysha Steel and Alloy provides a comprehensive guide on analyzing the composition of Stainless Steel 316 1500 Class flanges with the help of a simplified illustration. Stainless Steel 316 1500 Class flanges, having excellent resolving plastic and highly corrosion resistant properties, are the components of piping systems that are highly valued. It is very necessary to understand the dimensions of their correct installation and continue with the maintenance.

SS 316 Flanges manufactuere, supplier

The dimensions are classified into the Nominal Pipe Size (NPS), which is often from ½ inch to 24 inches with the pipe size the flange is designed to accommodate. The Flange OD (Outside Diameter) refers to the exterior diameter of the flange, including the area occupied by the bolt circle, while the Flange Thickness (T) is the thickness of the flange from the interior base up to the exterior edge of the diameter surface and varies upon the pressure class and nominal pipe sizes (NPS). The Flange Slight (H) is computed from the bottom covering of the hub to the top of the flange face and is critical for determining the amount of usable space in the piping system. Moreover, the diameter of the Bolt Circle Diameter (BCD), which is the diameter of the circle formed by the centers of the bolt holes, is also guaranteed which enables even distribution of the bolts during installation.

But, these characteristics should be understood properly since a flange must be chosen for the specific application and in the light of compatibility with the rest of the pipelines. Naysha Steel and Alloy provide the industry of the world with top brand stainless steel 316 1500 flanges that are tried and tested to fit any industrial requirement down to the very last detail, so that you no longer need to obsess over the stability of your installation.
