Technical Information

In our industry, there are two classifications of specs that govern how our products are made. Those categories are:

Dimensional Specs

These specs indicate what physical dimensions (size and shape) we will apply to the product we make for you. Primarily, we specialize in the ANSI B16 specs; they make up roughly 80% of our customer orders. As for outside diameter (OD), we can make flanges that range from ½” OD to 71″ OD.

Material Specs

These specs designate which raw materials your products will be made from. In general, flanges are made in SA-105 and LF-2
