Spectacle blind flange, is made by a steel spade and spacer, united by a welded handle. Spectacle blind may have a different type of joint face (RR Raised Face, FF Flat Face, RTJ Ring Joint), depending the type of flange.
The rtj spectacle blind flange is usually used on the oil line with two different function:
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.
The rtj spectacle blind flange is inserted between two flanges: in order to guarantee a perfect waterlight two gaskets are normally mounted, one on each side of rtj spectacle blind flange.
China Spectacle Blind Manufacturer Yaang supplies API 6A F51 RTJ Spectacle Blind Flange, 3-1/8 Inch, 5000PSI.

A spectacle blind flange is machined from a single piece of metal that is cut to match the pipe size, fit between two pipe flanges and requires an additional gasket when it is installed. Also, the bolts will need to be lengthened depending on what piping class and size blind is used. The thickness of the spectacle blind is specified based on the line pressure and pipe size.
API and ASME/ANSI flanges - comparing dimensions and pressure ratings
Although the dimensions of ASME and API flanges may sometimes be compatible for bolting - using the same bolt circle and the same number of bolts - they do not share the same pressure rating system.
ASME rates the pressure of a class based on the material of construction and the design temperature
API specifies allowable materials and gives it a specific pressure rating
The difference between ASME/ANSI and API is the fabrication material and a higher rated API operating pressure.
ASME/ANSI flanges are commonly used in industrial process systems handling water, steam, air and gas. API flanges are manufactured for high strength operating refinery systems with products such as oil and explosive gases.
The flange standards API 6A and ASME/ANSI B16.5 have the same dimensions - but the API 6A flanges are rated for higher pressures as indicated below:
