BL Flange

The function of blind flanges Blind flange, also known as blank flange, is a type of flange used to close the end of pipelines or containers. It is a solid disk with no openings or holes in the center. Blind flanges are typically used for the following purposes:   1. Closure: When a section of a pipeline needs to be closed off temporarily or permanently, a blind flange is installed at the end to fully seal it. This helps to prevent flow through pipelines and ensure the integrity of the system. 2. Adjust the flow rate and isolate the medium: When it is necessary to control or isolate the medium flow in the pipeline, blind flanges can play a role in flow regulation. 3. Inspection and testing: Blind flanges are commonly used for pressure testing, leakage testing, or visual inspection of pipeline systems. They provide a sturdy barrier that allows for safe and controlled testing without any fluid leakage. 4. Convenient for maintenance and repair: Due to its detachable nature, blind flanges are very useful in pipeline systems that require maintenance, cleaning, or overhaul. 5. Future expansion: In the event of additional pipeline sections being added in the future, blind flanges can be used as temporary closures until expansion occurs. It provides a convenient and safe way to seal the end of the pipeline until it is ready for connection. 6. Aesthetics and safety: Blind flanges can be used for aesthetic purposes when it is necessary to cover or hide the end of the pipeline. They also provide a safety measure to eliminate the risk of accidental entry or injury by sealing unused or open pipe ends. 7. Reduce production costs: In water or gas supply systems, the use of blind flanges can isolate or adjust parts of the pipeline that do not need to be used as needed, thereby reducing construction and maintenance costs.     During the use of blind flanges, the following points should be noted: 1. Ensure the sealing effect: The sealing performance of blind flanges is related to the safety of pipeline systems and the risk of environmental pollution. To ensure good sealing performance, correct installation, and firm fastening of the selected blind flange, in order to achieve a good sealing effect. 2. Choose a suitable blind flange based on pipeline pressure: According to the pressure level of the pipeline system, select the correct pressure level and size of blind flanges to ensure the safety and effectiveness of using blind flanges. 3. During installation, avoid damaging the pipeline: During the installation of blind flanges, extra caution should be taken to avoid human damage to the pipeline, which may lead to system leakage. 4. Regular inspections: Regularly inspect the installation of blind flanges, including sealing effectiveness and sealing performance.     Application scenarios of blind flanges in different industries 1. Industries such as petroleum, chemical, liquefied gas, and natural gas. In these industries, blind flanges are typically used for pipeline maintenance or on pipelines that require sealing when not used for fluid or gas transmission during a certain period of time. Blind flanges can prevent fluid or gas leakage, ensuring work safety while also avoiding environmental impact. 2. Pressure vessels. In pressure vessels, blind flanges are usually used to temporarily seal the inlet and outlet diameters for repair or accessory replacement work. 3. Food, pharmaceutical and other industries. Blind flanges can also be used in pipeline systems in industries such as food and medicine, especially when it is necessary to rotate or replace pipelines.     Blind flanges have multiple materials to choose from to meet specific requirements of pipeline systems, including carbon steel blind flange, stainless steel blind flanges, alloy steel BL flange, and other alloys blank flanges. They are manufactured in different sizes and pressure ratings to match the size and rating of the corresponding pipes.
