Blind Flanges are used for testing the flow of gas or liquid through a pipeline or vessel. It helps to close the end of piping systems or vessel openings. It allows easy access to the pipeline when there is a requirement to work done inside the line. They are used in high pressure applications available in all grades, materials, size and specifications.
Blind pipe flanges are typically provided with a raised face, flat face, or RTJ facing. The standard height is 1/16" when a raised face is required under 400#. The standard height is 1/4".for blind pipe flanges of 400# and above. Hebei Mingda manufactures blind pipe flanges in various materials such as stainless steel, carbon steel, alloy steel and monel according to the various standard ANSI/ASME/ASTM according to the customer requirement.
