Stainless Steel Plate Flanges

Applications

These plate flange reference tables detail outside and inside diameter sizes and bolt hole drilling pattens for various standard plate flanges. They are intended for estimating purposes only. Applications vary, confirm all dimensions with your engineering department prior to ordering.

Standard Flanges

Stainless Plate Products produces a wide variety of flat face slip-on flanges (also known as hubless or plate flanges). These high quality plate flanges have a wide variety of applications.

ASME/ANSI
B16.1-1989
ASME/ANSI
B16.5-1996

Advantages

Stainless steel plate flanges are produced from quality mill plate. Mill plate produced to the ASTM A240 and ASME SA240 standards is virtually free of voids, non-metallic inclusions and other defects. The inherent corrosion resistance of stainless steel is enhanced by the superior grain structure offered by plate products over forged or cast products.

As companies begin to look at life-cycle costing models, in almost every case, the slightly higher initial cost of stainless steel plate flanges is more than offset by the extended service life and the reduction of the normal maintenance costs.

Stainless steel plate flanges are a widely accepted alternative to cast or forged flanges in low pressure applications.
