Detailed Information:

RatnaExports.com is a reputed paddle spacer 304 Manufacturer in India, per the ASME B16.48 standard. Our offered Spade and Spacers, commonly called Line Blinds, are similar to Spectacle Blinds in that they function similarly. The spade or spacer is installed between two flanges and is bolted to the wall. When the line needs to be open, the Spade Ring Spacer is used, and if it needs to be blocked or closed, the Paddle Blind or Spade or Spade is used. A Paddle Spacer can be swapped over from an open to a closed position by removing only half of the bolts and swapping the Paddle Spacer for the ring spacer. The bolts are then re-installed and tightened. The handle on the pipe will indicate whether the Spade Spacer or the Ring Spacer is being used.

Typically, it is common for a Spade Blind or Paddle Spacer to have a hole on the handle, whereas a Spade Blank or Paddle Blind does not have a hole on the handle. For large sizes, Spades Paddle Blinds and Spacers are the preferred choices. The Paddle Spacer 304 is most commonly used for maintenance when a section of pipe or a device needs to be isolated. Thus, since this is semi-permanent isolation and safe, it is best to use a Spade and Spacer in maintenance operations to ensure safety.

There is no doubt that RatnaExports.com is one of the leading suppliers and exporters of Paddle Spacer 304, also known as paddle blinds and blanks. This type of flange is a significant member of the line blind family. This equipment is not of the contemporary type, but it is equipped with pipes to isolate a pipe and segregate it, blocking the flow completely. Many different materials are available to us, such as Inconel, stainless steel, and others. 

Aside from the fact that these are very portable and lightweight, there is no doubt that they are ideal for industries with limited space because of their lightweight and portability. However, they are also beneficial for industries with limited space because of their portability and lightweight. Aside from the fact that it is made of a sole metal disc with a handle, it is also equipped with flanges sized to fit pipes of an outsized diameter. Our company aims to provide high-quality paddle flanges to its customers continuously, as we keep all international norms or industry guidelines in mind when making these paddle flanges. There is usually a period during which pipelines are cleared and maintained, along with a period during which they are being maintained.
