Product Description

Huazhan Steel Blind Flange

Product Description

A blind flange is a solid steel piece with no bore (interior diameter) and primarily designed to cap off a line. As the majority of flange connections allow for the passing through of air or fluid via an interior opening, blinds give the ends of pipe connections a well formed termination point or rerouting of the media in question towards another portion of the pipe assembly.Opt for a blind flange in these cases, as well as in instances when a pipe line requires a future modification such as the installation of a valve or fitting to reroute flow.

We have many carbon steel and stainless steel Blind Flanges, or steel end-caps, in various sizes and ASME ratings in stock. Additionally, we can manufacture your metal pipe flanges in any available alloy upon request. We can coat our carbon steel products with various options to prevent rust. These options include flat black paint, galvanized coating, zinc plating, and yellow zinc chromate plating. Customers can request any of these coatings for their products.

Face Types Of Blind Flanges:
Raised Face Blind Flange: It has a raised serrated surface around the center for improved sealing. Typically utilized with a spiral wound gasket.

Flat Face Blind Flange: This type of blind flange contains a flat surface, suitable for low-pressure applications. Typically paired with a rubber/neoprene gasket.
Ring Type Joint (RTJ) Blind Flange: This type utilizes a metal ring gasket for high-pressure and high-temperature applications. A gasket is usually metallic.
High Hub Blind Flange: It combines the characteristics of a blind and the extension of a hub flange for added strength.

Benefits Of Using Blind Flanges:
* Leak Prevention:Blind flanges create a secure seal, preventing leaks in the pipeline.
* Maintenance Convenience:They make it easy to isolate sections for maintenance without disrupting the entire system.
* Pressure Relief: Blind flanges can be used for pressure relief when necessary, typically when ports are created in their body.
* Safety: They ensure safety during pressure testing and maintenance by blocking off hazardous substances.
* Versatility: Blind flanges are suitable for various pipe materials and sizes.
* Cost-Efficiency: They are cost-effective solutions for sealing pipe ends and reducing downtime.
* Easy Installation: It is simple to install and remove as needed.
* Longevity: Blind flanges are durable and corrosion-resistant, extending their lifespan.
* Customization: They come in various materials, including stainless steel, carbon steel, and more, to suit specific applications.
* Adaptability: Blind flanges are suitable for high-temperature and high-pressure environments.
* Reduced Maintenance Costs: They minimize the need for frequent maintenance and repairs.
*No Flow Restriction: Since they have no bore, blind flanges do not obstruct flow when not in use.
* Uniform Stress Distribution: They distribute stress evenly across the flange face.
* Compatibility: They are compatible with different flange types, making them versatile in various systems.
* Enhanced Safety: They reduce the risk of accidents and environmental damage by providing a reliable closure.

 

Applications:
* Pressure Testing: Blind flanges seal off pipeline sections during pressure testing, ensuring safety and accuracy.
* Isolation: They are employed to isolate sections of a pipeline for maintenance or repairs, preventing the escape of hazardous substances.
* Temporary Closure: When a pipeline is temporarily not in use, blind flanges can seal it off securely.
* End Cap: Blind flanges are often used as end caps in vessels and tanks to maintain pressure or remove contaminants.
* Instrumentation and Inspection Ports: They can serve as access points for inspection or the installation of measurement instruments like pressure gauges and thermometers.
