Blind Socket Weld Flange

E S Haji & Co , the leading Flange Manufacturer in Chennai talks about Blind Socket Weld Flanges in this blog, giving an outline of where it is used and why it is used and focusing on the salient key features. Thus, making it easier for the customers to understand the product better and make their choice accordingly.
In this Blog E S Haji & Co renders the reason as to why Slip-On Flange is the most common type in the flange industry and enhances the purposes it serves in the industrial sector.

Socket weld flanges are similar to a slip-on flanges in outline, but the bore is counter–bored to accept pipe. The diameter of the remaining bore is the same as the inside diameter of the pipe. Socket welds have an internal recess on the inside diameter to allow for a smoother flow of the process fluid. The positive of this is that is creates a smooth bore with the proper welding and grinding. The negative of this type of flange is that it can be more expensive than a slip-on due to more intricate machining, and they can be less readily available than slip-ons due to the fact that the bottom half of the inside diameter must be made to the same schedule as the pipe that is being used(you must specify the schedule needed). The socket weld flanges are attached to the pipe by a fillet weld around the hub of the flange. An optional interval weld may be applied in high stress application.

Why is it used ?
Blind flanges are used to blank off the pipeline, valves or pumps. These flanges can also be sometime used as a inspection cover. E S Haji ‘s range of blind flanges can be customized to meet the specifications and requirements of the clients.

Where is it used ?
The Socket Weld Flanges were initially developed for use on smaller sizes of pipe at higher pressure ratings. Socket weld flange’s biggest use is in high pressure systems such as hydraulic and steam lines. They are used on lower pressure temperature as well today. E S Haji & Co offers these flanges in carbon steel and stainless steel.

Key Features
The recess on the inside diameter allows for a good fit of the pipe allowing for a smooth flow of liquid.

Work well for smaller sizes and higher pressure temperature conditions.

Similar to slip-on flanges, but must specify the pipe schedule they will be used for with socket welds.
