Class 300 Flanges
We are highly recognized in this field of manufacturing and supplying the huge range of technically sound Class 300 Flanges. These are all in confirmation to ANSI-B16.5 Class 300 Slip-on standards and are widely demanded for various industrial applications. We have made use of various materials in fabricating these ranges like Carbon Steel, Alloy Steel, Stainless Steel, Mild Steel and that too available in all grades. These are highly suitable with the application to relatively low pressure piping systems.
