Introduction to Flange Plates for Connecting Equipment and Installation Principles and Application Standards of Flanges
Introduction to Flange Plates for Connecting Equipment:
Flanges are used in pipeline systems that handle corrosive media. They are available in various stiffness levels to suit different pressure requirements. For example, flanges with lower rigidity are suitable for pressures up to 4 MPa, while welded flanges with higher rigidity are ideal for high-pressure and high-temperature applications. Flanges are typically made from carbon steel, and they are commonly known as Datong flanges. Datong flanges are used to connect two large-diameter pipes.
A typical flange connection consists of two flanges and multiple fastening bolts. Large flanges are manufactured from carbon steel. Low carbon steel offers excellent plasticity and low strength, and when the right amount of carbon is added, it becomes hard with reduced plasticity. Flange connections often need to withstand high tensile, compression, transverse, and shear forces. Large flanges are an excellent choice for such applications.
Flange connections are used to connect two pipes, pipe fittings, or equipment, as well as to connect two flanges, flange gaskets, and bolts. Some fittings and equipment come with their own flanges. Flange-threaded connections, flange welding, low-pressure small-diameter butt-welded flanges, and high-pressure and low-pressure large-diameter butt-welded flanges are commonly used.
Installation Principles and Application Standards of Flanges:
High-pressure flange connections secure two pipes, fittings, or devices between two flanges and connect them using bolts. Low-pressure small-diameter threaded joint flanges, high-pressure and low-pressure large-diameter butt-welded flanges, and welded flanges are used based on different pressure levels. The thickness of flanges and the diameter and quantity of connecting bolts vary depending on the pressure. Different high-pressure flange connection methods, components, and equipment are required according to specific conditions, so the detailed equipment components and devices are determined accordingly.
Flange gaskets also vary in material based on different pressure levels, ranging from low-pressure asbestos gaskets to high-pressure asbestos gaskets and metal gaskets. Large flange connections are convenient and can withstand substantial pressure. Flange connections are widely used in industrial pipelines. High-pressure flange connections are primarily used in pipe equipment. High-pressure flange connections play a vital role in pipeline construction, and the connection between the receiving end and the pipeline is of great importance and value. High-pressure flange connections secure two pipes, fittings, or devices between two flanges and fasten them with bolts to complete the connection.
High-pressure carbon steel flange blanks are often exposed to high-temperature and high-pressure conditions. Under the influence of high-temperature flue gas and steam, pipes may oxidize and corrode. Carbon steel flanges require steel pipes to exhibit high durability, oxidation resistance, corrosion resistance, and good structural stability. High-pressure carbon steel flange blanks are used in the manufacturing of superheater tubes, reheater tubes, pipelines, main steam pipes, and more for high-pressure and ultra-high-pressure boilers.
SIB16.5 carbon steel flange systems have a pressure rating of 150 pounds, with RF (Raised Face) representing the sealing surface type for carbon steel flange blanks. The -48 indicates that the standard size for carbon steel flange blanks ranges from 18 inches to 48 inches, and carbon steel flange blanks can be obtained through conventional processing.
