Product Description Product DescriptionBLIND FLANGEBlind Flange is a solid disc-shaped pipe flange without a center hole. It is used to close the end of the pipe or to block a section of the pipe. It is detachable. Blind flange is an indispensable component for end blocking or maintenance isolation in the pipeline system.STRUCTURAL ADVANTAGESComplete Sealing And Isolation Capability:The blind flange is a solid structure with no center hole. It can completely block the pipeline fluid and achieve complete sealing. It is the most reliable sealing component at the end of the pipeline or the isolation section, which can prevent the leakage of the medium, seepage, or the entry of foreign impurities.The Structure Is Extremely Simple, And The Strength Is High:The blind flange is directly processed from a solid metal plate, which effectively avoids the structural weaknesses of conventional flanges such as center holes and openings. The overall force is more uniform, and the strength is higher than that of the perforated flanges of the same specifications, which is more suitable for pressure-bearing occasions.Easy To Install And Disassemble:It is consistent with the appearance of the standard flange plate, and can be tightened or loosened with the other flange by bolts at any time. It is quick and convenient to install, repair, or replace, and is suitable for frequent disassembly and temporary closure applications.Product ParametersTECHNICAL PARAMETERSProductsSteel FlangeFlange Size1/2"-24"; DN15-DN600Flange Class150#; 300#; 400#; 600#; 900#; 1500#; 2500#Flange MaterialCarbon Steel; Stainless Steel; Duplex Steel; Copper Nickel Etc.Flange Material GradeASTM A105,ASTM A350 LF1.
