Blind Flanges Manufacturer

Specialized Blind Flanges Manufacturer, ASME B16.47 / ANSI B16.5 Dummy Flange Dimensions, BLFF Flange, BLRF Flange.

Blind flanges don’t have a center hole, and are used to blind and seal a pipeline, A pressure vessel, and block the inflow of the fluid. Blind flanges allow easy to access the pipelines, as they can be fluently unbolted to let the operator execute conditioning inside the terminal end of the pipe.

Blind Flanges are manufactured without a bore and used to blank off the end of the pipelines, and pressure vessel openings. Blind Flanges, particularly in the larger sizes, are the most largely stressed-out flange types. However, utmost of these stresses are bending types near the center, and since there’s no standard inside perimeter, these flanges are suitable for advanced pressure temperature applications.

We are supplying blind or dummy flanges to petrochemical, oil, gas, and allied industries in the USA, UK, Qatar, Mexico, Nigeria, Saudi Arabia, Kuwait, Iran, Kazakhstan, Bahrain, Vietnam, Indonesia, Norway, Ghana, Colombia, Azerbaijan, Libya. We are having a large inventory of ASTM A105 Blind Flange, Series A and Series B Blind Flange, Class 150, Class 300, Class 600, Class 900, Class 1500, Class 2500, Blind Flanges, EN 1092-1 Type 05 Blind Flange, AWWA C207 Class D, Class B.
