Detailed Information:

RatnaExports.com  a leading manufacturer, supplier, and exporter of Spade Flanges, also known as Paddle Blanks and Blinds, as part of the line blind family, is a leading manufacturer, supplier, and exporter. Stainless Steel Spade Flanges are temporary devices installed on pipelines to segregate fluids or isolate a pipe by blocking the flow entirely. In addition to being lightweight and portable, our Inconel Paddle Blanks are also a great boon in industries that face space problems. Used single stainless steel blind was used to manufacture a compact metal disc with a handle and flanges of large-diameter pipes. They come with a handle as well. We are known for providing high-quality products at affordable prices. During the maintenance and cleaning of pipelines, Various metals will be using ANSI B16.48 Spade Flanges.

Using the Spade Ring Spacer if you intend to open the line is recommended while using the Paddle Blind or Spade if you want to block or close the bar. Changing from an open to a closed position is as easy as removing half of the bolts and switching over the Paddle Spacer. The removed bolts are then installed and tightened. A handle is attached to the pipe, indicating whether it is a Spade or a Ring Spacer installation.

Spade Blanks and Paddle Spacers with smaller sizes tend to have holes in the handle, while Spade Blanks and Paddle Spacers do not. It is preferred to use Spade Blinds and Spacers in larger sizes. Paddle Blanks are utilized in maintenance when it is necessary to separate a section of pipe or isolate a device. Use a Spade and Spacer during maintenance operations for safety reasons because this is semi-permanent isolation.

Many flanges, ranging from cast rings to forged ones, are used to join steel pipes mechanically or to join lines to pressure pumps, vessels, valves, and other equipment. The same standard flanges may have a flat or raised face.

RatnaExports.com is one of the leading suppliers of stainless steel flanges, in particular grades such as SS 304, 304L, 316L, and 904L, for corrosion resistance, durability, and many other physical properties. There is a high regard for stainless steel.
