How Are The Pressure Levels Of Common Flanges Divided?

Different flanges are commonly utilized in various settings, leading to varying pressure levels. In chemical engineering, for instance, the primary application of large stainless steel flanges is in high-temperature resistant pipelines. Consequently, these flanges possess exceptional material strength, giving them an excellent capacity to withstand high pressures.

Hence, forged flanges are frequently requested by customers due to their enhanced pressure-bearing capacity resulting from the forging process, which increases the structure's density. Therefore, customers often find it necessary to obtain forged flanges in order to meet their specific requirements.

Large stainless steel flanges are categorized into different grades such as PN25, PN6, PN10, PN16, PN25, PN40, etc., based on their compression resistance. The compression resistance requirements for these flanges are clearly defined in both domestic and international standards. Among them, PN10 and PN16 are the most commonly used grades. Flanges, also known as flange flanges or flanges, play a crucial role in connecting shafts and pipes. They are used to join pipe ends and connect equipment, such as reducer flanges, to the inlet and outlet of equipment. The standards ensure the quality and performance of these flanges, making them highly reliable in various applications.

A flange connection or flange joint is a type of connection consisting of flanges, gaskets, and bolts that work together as a unified sealing structure. This detachable connection allows for easy assembly and disassembly, with the flanges serving as the main connecting elements. The use of gaskets ensures a tight seal, while bolts secure the joint tightly in place. This type of connection is commonly used in industrial applications, such as piping systems, mechanical equipment, and structural components, where reliability and strength are critical.

The strength series of a flange is represented by its pressure rating, which is not identical to the design pressure but has a certain correlation with it. As the pressure level increases, the flange's strength also increases. It is crucial to note that the pressure rating serves as a measure of the flange's ability to withstand higher pressures.

When selecting a pipeline for a process device, it is important to consider the material, design temperature, and design pressure in order to determine the appropriate pressure level. This can be accomplished by referencing the temperature and pressure curve found on the flange standard, which helps to determine the appropriate pressure level for the pipeline. Once the pressure level has been determined, it becomes easier to select the appropriate valves and other pipe fittings to ensure proper operation and safety. Therefore, taking these factors into account is crucial when designing a pipeline system for a process device.

Flange standard systems classify pressure levels into European and American systems, namely PN1.6, PN2.5, and CL150/PN2.0. In some cases, these standards are combined when dealing with hot environments. As flanges are utilized in diverse applications, their pressure levels vary accordingly. For instance, in the field of chemical engineering, large stainless steel flanges find usage in high-temperature resistant pipelines, resulting in excellent material strength to withstand pressure. This claim stresses the importance of considering pressure-bearing performance in relation to the specific application of flanges.

The increased density of a structure is one of the main reasons why customers frequently request forged flanges. This is because the forging process enhances the material's density, making it incredibly durable and able to withstand significant pressure and stress. As a result, forged flanges are often the preferred choice for a wide range of industrial and manufacturing applications, where durability and reliability are of utmost importance. By utilizing forged flanges, companies can ensure that their equipment and machinery is built to last, delivering optimal performance and minimizing the risk of breakdowns or downtime.
