Most applications, in particular, the oil and gas industry prefer equipment that lasts longer while also delivering excellent performance. Materials that can enhance the performance of a component. Usually, Stainless Steel Spectacle Blind Flange works well in highly corrosive areas. Grades like 316 or as referred to as marine grade steel are useful for marine engineering purposes or for use in coastal regions like docks etc. These areas are susceptible to getting corroded by exposure to salt sprays or seawater. For high-temperature applications, buyers have the choice of selecting alternatives like grade 321 or grade 347 to produce the ASME B16.48 Spectacle Blind Flange. Similarly, high-pressure applications require standard flanges. Which is why the range available for EN 1092-2 Spectacle Flange Pressure Ratinge ranges between class 150 to class 2500. For a cost efficient alternative manufacturers often recommend the use of Carbon Steel Spectacle Blind Flange.

But the drawback of using carbon steels is that they lack the corrosion resistance properties like stainless steel, making them an especially our choice in highly corrosive environments. Yet, these flanges are really hard and have good toughness. Like most flanges, it is possible to customise ASTM A350 LF2 Spectacle Blind Raised Face Dimensions per the requirements of the applications. This type of flange also consists of parts like thes Spectacle Blind Figure 8 ASME B16 48 which aid the worker in regulating the flow of media across piping systems.
