EN 1092-1 is a European standard that specifies flanges and flange connections. Specifically, it specifies the requirements for the size, design, materials, and testing of flange connections. This standard is mainly used for the connection between pipeline systems and equipment, ensuring the reliability and safety of the connection.
Scope and Application
EN 1092-1 is applicable to flanges and flange connections, which are mainly used in liquid and gas pipeline systems, including industrial, construction, and utility fields.
Dimensions
The standard specifies a series of standard dimensions, including flange diameter, hole diameter, number and diameter of bolt holes, etc.
Design
The standard defines the design requirements for flanges, including the shape, grooves, and geometric characteristics of flange connections. This helps to ensure that the flange can withstand pressure and temperature under various working conditions.
Materials
The standard specifies the materials used in flange manufacturing, which helps ensure that flanges have the required chemical and physical properties in specific environments.
Testing
The standard has conducted a series of tests on flange connections to ensure that they meet the standard requirements. This includes pressure testing, sealing performance testing, and inspection of geometric characteristics.
Marking
EN 1092-1 requires relevant information to be indicated on the flange, such as manufacturer identification, size, material, etc., so that users can correctly select and install the flange.
The EN 1092-1 standard covers various types of flanges to meet different pipeline systems and engineering requirements. The standard defines a range of flange types.
Flange types
EN 1092-1 includes different types of flanges, such as Plate flange, Welding Neck flange, Slip-on flange, Blind flange, etc. Each type of flange has its unique purpose and design characteristics.
Pressure rating
The standard defines flanges with different pressure ratings to meet pressure requirements in different engineering and applications. The pressure rating is usually represented by PN (Pressure Normal), such as PN6, PN10, PN16, etc.
Size range:
EN 1092-1 specifies a standard size range for a series of flanges, including the diameter, aperture, number and diameter of bolt holes, etc. This ensures that flanges can be compatible for use in various piping systems.
Material:
The standard specifies the material requirements for manufacturing flanges, which helps to ensure that flanges have the required chemical and physical properties under specific operating conditions. Common flange materials include carbon steel, stainless steel, alloy steel, etc.
Connection methods:
The EN 1092-1 standard covers different connection methods, such as bolted connections, butt welded connections, etc., to meet different engineering and installation requirements.
