Manufacturer Of ANSI B16.5 Raised Face Blind Flange In India, Check DN15-1200 3000lbs Forged Carbon Steel Flanges Dimensions And Weight Chart, schedule 10 Ductile Iron Blind Flange At Lower Prices Compared To USA & UK.

ASME B16.5 Blind Flanges have diameters from ½ inches to 24 inches and they are made up of different materials. They are also made in different shapes according to the need. BLRF flange has a raised face which allows for much grip at installation and high tensile strength. Blind flange dimensions vary according to the specifications and types. Blind flange weight is important in considering for which application it is used for. Blind flange raised face will add up weight. the Blind flange weight chart can show the difference in weight for different material composition for bling flanges and raised face ones. Blind flange manufacturers in India produce different dimensions, weights and shapes of the stainless steel blind flange.

A comprehensive Blind flange size chart will provide an idea of the dimensions and blind flange sizes. ANSI Blind flange sizes for B16.5 specification range up to NPS 24. The thickness of the wall in the class 300 blind flange dimensions would be lower than the thickness of a class 150 flange due to the additional pressure it is excerpted onto.


What is Stainless Steel Blind Flange?


ASME B16.5 Stainless Steel Blind Flange Manufacturer in India

The classes are a way of blind flange pressure rating that allows customers to order the correct class for the appropriate need. Blind flange price in India is very competitive. It varies from supplier to supplier. The qualities differ as well. ASME B16.5 blind flange dimensions constitute to the price too. The smaller the size, the lower the weight and lower the price. Dimensions of the Stainless Steel Blind Flange can be different with different specification methods as well. The PN series is a way of specifying the pressure class in bars and the properties such as the hole size and bolt circle diameter. For example the pn16 blind flange dimensions would align with the PN number which is 16.
