The DN100 flange is a critical component in piping systems, designed to connect pipes with a nominal diameter of 100 millimeters. It is widely used in various industries, such as water treatment, chemical processing, and oil and gas, thanks to its durable design and capacity to endure high pressures and temperatures. Commonly manufactured from materials like carbon steel and stainless steel, or alloy steel, DN100 flanges come in different types, including slip-on, weld neck, and blind configurations, to suit specific application needs. Their reliable performance and ease of installation make DN100 flanges essential for ensuring the integrity and efficiency of fluid transport systems.
Characteristics Of DN100 Flanges
Indicates the diameter of both the flange and the connected pipe. For DN100, this corresponds to 100 mm.
DN100 flanges are available in various pressure ratings, typically categorized as Class 150, Class 300, Class 600, and so on. These ratings represent the maximum pressure the flange can safely handle at a given temperature.
The thickness of the flange varies depending on the type and pressure rating, with thicker flanges used for higher pressure applications.
Types Of Flanges
Slip-on flange is designed to slide over the pipe and is then welded in place. Its ease of alignment and installation makes it a preferred option for various applications.
Weld neck flange features an extended tapered neck that is welded to the pipe, it offers exceptional strength and resistance to high pressure. It is often used in high-stress applications.
A blind flange is a solid flange that covers the end of a piping system, used to seal off a section of the pipeline.
Installation Of DN100 Flanges
- Ensure that the surfaces of both the flange and the pipe are clean and free from any debris. Inspect for any damage or defects;
- Align the flange with the corresponding pipe or fitting. Proper alignment is crucial to avoid stress on the flange and ensure even pressure distribution;
- Insert bolts through the flange holes and tighten them in a crisscross sequence to apply uniform pressure. The use of a torque wrench is recommended to achieve the manufacturer's specified torque values;
- For welded flanges, apply welding procedures as per industry standards. Ensure that the welds are inspected for quality and compliance;
- Perform pressure tests to confirm the integrity of the connection. Look for leaks and ensure that the flange can withstand the intended operating pressure.
Considerations For Choosing DN100 Flanges
Take into account the particular requirements of the application, including pressure, temperature, and fluid type, to choose the appropriate flange type and material.
Ensure that the selected flanges comply with relevant industry standards, such as ASME, ANSI, or API, to guarantee compatibility and safety.
Choose a flange type that aligns with the installation method available on-site, whether it be welding, threading, or bolting.
