Understanding the China DN100 Flange Specifications and Applications

Flanges play a critical role in various piping systems, providing essential connections between pipes, valves, and other equipment. Among the many types available, the China DN100 flange has gained notable prominence in industrial settings, particularly in water supply and oil and gas transportation. This article aims to delve into the specifications, materials, types, and applications of the DN100 flange, shedding light on its importance in modern engineering.

Specifications of DN100 Flange

The term DN stands for Diameter Nominal, which is a standard measurement used to denote the nominal pipe size. In the case of the DN100 flange, it corresponds to a nominal diameter of 100 millimeters, or approximately 4 inches. This dimension is crucial as it affects both the flow capacity and the compatibility of the flange with pipes and fittings of the same nominal size.

The standard specifications for flanges in China generally adhere to the GB (Guobiao) standards. For the DN100 flange, the commonly referenced standards are GB 9113 (for slip-on flanges) and GB 17241 (for welded neck flanges). These standards dictate the dimensions, tolerances, and pressure ratings, ensuring a reliable and consistent product across various manufacturers.

Materials Used in DN100 Flanges

DN100 flanges are available in various materials, which impact their suitability for different applications. Common materials include

1. Carbon Steel Often used for its strength and durability, carbon steel flanges are suitable for low to medium pressure applications. 2. Stainless Steel Offering excellent corrosion resistance, stainless steel DN100 flanges are ideal for applications involving water, chemicals, or high-temperature environments. 3. Ductile Iron Known for its superior strength and wear resistance, ductile iron flanges are frequently used in municipal water systems. 4. Plastic For specific applications, especially in corrosive environments, plastic flanges can be employed due to their lightweight and non-corrosive properties.

Types of DN100 Flanges

There are several types of DN100 flanges, each designed for different purposes

1. Slip-On Flange This design allows the pipe to be slipped into the flange, making it easier to align during installation. It’s commonly used in low-pressure applications. 2. Weld Neck Flange Known for its tapered hub, this flange type is welded to the pipe, providing greater strength and resistance to high pressures. 3. Blind Flange Used to close the end of a piping system, blind flanges are essential in pressure applications where future access may be desired. 4. Socket Weld Flange Suitable for smaller-sized pipes, this flange quickly connects to a pipe by inserting it into the socket and welding around it.

Applications of DN100 Flanges

The DN100 flange's versatility makes it suitable for a wide range of applications. In the oil and gas sector, these flanges are routinely used in pipeline systems to connect different pieces of equipment. In water treatment facilities, DN100 flanges are often employed in pipes that transport potable water or wastewater, ensuring tight seals and preventing leaks.

Moreover, the construction industry utilizes DN100 flanges in various projects, from building water supply systems to installing HVAC systems. As industries continue to evolve, the demand for reliable and standardized flange solutions like the DN100 will remain high.

Conclusion

In summary, the China DN100 flange is an essential component in modern engineering, with its specifications, materials, types, and diverse applications highlighting its significance across various industries. Understanding these aspects can help engineers and procurement professionals make informed decisions when selecting flanges for their projects, ensuring efficiency and reliability in piping systems.
