Stainless Steel Blind Flange
Class 300 Blind Flange Manufacturers, Check Price List of Dn100 PN16 Blind Flange
Dinesh Industries is a manufacturer and supplier of stainless steel pipe fittings in different grades and scales. We manufacture flanges of all types as well. Our Stainless Steel Blind Flange is used widely in applications where the pipeline has to be terminated. The blind end or the plate of the flange seals the connection so that the flow ends with the blind flange. As a leading Stainless steel blind flange manufacturer we supply these flanges in different types of stainless steels. The 304, 316 and duplex are some of the most commonly used materials for applications that use flanges.

Our SS blind plate flanges can therefore be made with any of these material grades depending on the application’s material grade. Also, there are standards to cover the different dimensions of the flanges. The SS blind flange ANSI /ASME B16.5 for example is a specification that covers the flanges ranging from ½ inches in nominal size to 24 inches. Likewise, there are other specifications that cover different SS blind flange dimensions for different purposes. We produce flanges with international quality standards and test them before supplies. We are also a stockiest of the SS blind flange en 1092-1 and other types. Please contact us for more product information and supplies.
