B16.5 A105 Carbon Steel Blank Flange Product introductionFigure-8 Blank, also known as figure 8 flange or spectacle blind flange which is combination of the two that can be rotated to function as Single Bind or a Ring Spacer. This kind of flange is generally a piece of metal than is cut to fit between two pipe flanges and usually sandwiched between two gaskets a spectacle blind is often made from two metal discs that are attached to each other by a small section of steel. The shape is similar to a pair of glasses or spectacles - hence the name spectacle blind flange. One end of the blind will have an opening to allow flow through the pipe during operation and the other end is solid to block flow during maintenance. They are generally installed as a permanent device to separate process piping system.Spectacle Blind Flange  is usually used on the oil line with two different functions:If the spade is put in between the flanges, it stops the fluid's passage;If the spacer is put in between the flanges, the passage of the fluid is allowed.SpecificationTypesSpectacle Blind Flange/Figure-8 Blank/Figure-8 Flange StandardsASME B16.48MaterialsCarbon steel A105, A516 Gr. 60/65/70, A350 LF2, A694 F60-65, stainless steel A182 F304/304, F316/316L, alloy steel AISI Gr.1, Gr.5, Gr.9, Gr.91, Gr.11, Gr.22,duplex stainless steel F51, F53, F55, F44,DimensionsFrom 1/2" NPS to 24" NPSPressure ClassFrom class 150 to class 2500, PN6, PN10, PN16, PN25, PN40, PN64 Face Type Flat Face (FF), Raised Face (RF), Ring Type Joint (RTJ)Surface treatmentPolished version on request Inspection/testDirect-reading Spectrograph, Hydrostatic testing machine, X-ray detector, Ultrasonic flaw detector, Magnetic particle detectorMill's certificateEN10204 3.1 Marking Buyer or seller's logo/standard/material/dimension/heat noPacking In wooden case or carton box depends on quantity Lead time 3 days for stock, 15-20days for fresh production depends on quantityCompany ProfileFrom 1989 to now, Kingmetal Steel focus on manufacturing and distributing pipeline products including piping, fitting, flange, valve and fastener in stainless, carbon, alloy and duplex steel.
