ANSI B16.47 Series A BL Flange is a large diameter flange that follows the American National Standards Institute (ANSI) B16.47 standard. It belongs to the blind plate (BL) flange of Series A. The following is its introduction:
Standard Specification
ANSI B16.47: This standard is mainly for large diameter steel flanges, including provisions on dimensions, tolerances, materials, pressure-temperature grades, etc., to ensure the interchangeability and reliability of flanges in large diameter pipeline systems. Series A is generally applicable to large diameter sizes within a specific range.
Material Properties
Material such as carbon steel, stainless steel, and alloy steel are usually used. Different materials are suitable for different working environments and media to meet the requirements of large diameter pipeline systems in terms of strength and corrosion resistance.
Structural Features
Blind plate structure: BL means blind plate. This flange has no through hole in the middle. It is used to block the end of large diameter pipelines to prevent medium leakage and ensure the safety and normal operation of the pipeline system.
Large size: Suitable for large diameter pipelines. Due to its large diameter characteristics, more structural strength and stability factors need to be considered to withstand the pressure of the medium in the pipeline.
Application areas
Petrochemical: In the petroleum and chemical industries, it is used for end plugging of large-diameter pipeline systems, such as at the ends of large storage tanks and transmission pipelines in refineries and chemical plants, to ensure system safety and convenient maintenance.
Natural gas: In large-diameter pipeline systems for natural gas transportation, especially at the ends or branches of long-distance transmission pipelines, it can effectively seal and isolate the pipelines.
Electricity: In large-diameter pipeline systems such as steam and water supply in large thermal power plants, it plays a role in sealing and isolation to ensure the normal operation and maintenance of equipment.
