Spade Flange manufacturer

ANSI B16.5 Stainless Steel Paddle Blanks and Spade Blind Flange manufacturer in India

Flange is a plate or ring which can be formed as a rim to end the pipe which connects two pipes, valves or pumps. It is usually welded or screwed. There are many types of flanges and are available in various sizes. A spectacle blind flange is generally used to fit between two pipe flanges. There are 3 types of spectacle flange, such as spacer flange, spade flange and spectacle blind flange.

Spade Flange

Spade blind flange is also known as spectacle blind flange, it is a metal disc which is attached to the pipe and its one end is opened or blocked in order to allow or block the flow of the liquid whenever required. Blind spade flange is a solid flange whose main purpose is to block one section of the pipe when it is not in use. Similar to standard pipe flange, this is also raised face or flat faced. Ring gasket is use for raised f ace and full-face gasket used for flat faced. This reversible spade flange is used in industries like chemical, pipeline and other allied industries. The standard form of flange is ASME 16.48 Flange. The diameter of this depends upon the size and thickness of the pressure class of flange. The materials used in this are stainless steel and carbon steel. ASME 16.48 Spade flange is thus manufactured by our Regal Sales Corp. as this is the oldest steel firm in India.

What Does Spade Flange means ?

Spade flange is a round piece of metal that is fixed between the flange and the bolts are being screwed. This shuts down the pipe, to prevent the mixing of polluted water and allows the engineers to work on the pipeline. This is also known as paddle blanks and blinds. It is usually design in pipeline industry for extensive pipe cleaning operations. These are used to stop the performance of the pipeline during maintenance period and these are more reliable than isolation Valve.
