Understanding PN10 and DN100 Specifications
What is PN10?
PN (Pressure Nominal) indicates the maximum pressure that a flange or valve can withstand at a specified temperature. PN10 signifies that the component can handle a maximum pressure of 10 bar (approximately 145 psi). This rating is critical for ensuring that the component can operate safely under expected conditions. For example, the components rated at PN10 are generally used in water and waste treatment applications, where pressures are relatively low but reliability is essential.
What is DN100?
DN (Diameter Nominal) refers to the nominal diameter of the pipe or fitting in millimeters. DN100 indicates a nominal diameter of 100 mm, or approximately 4 inches. This standardization allows for compatibility between various piping systems and components, making it easier to replace and repair parts. DN100 components are widely used in various industries, from petrochemical to municipal water systems.
Types of PN10 DN100 Components
Weld Neck Flanges
Weld neck flanges are commonly used in high-pressure applications. They feature a long neck that provides a smooth transition from the pipe to the flange, reducing stress concentration. Their design allows them to be welded directly to the pipe, making them suitable for high-stress environments. Companies like www.valvias.com and www.wermac.org offer a range of weld neck flanges in DN100 size.
Loose Flanges
Loose flanges, also known as lap joint flanges, are used primarily for low-pressure applications. They consist of two parts: a stub end and a flange that can slide over the stub end. This design allows for easier alignment and installation, making them ideal for temporary installations or situations where frequent disassembly is necessary. www.gteek.com provides a variety of loose flanges suitable for DN100 applications.
Gate Valves
Gate valves are essential components for regulating flow in piping systems. They are designed to be fully open or fully closed, providing a tight seal when closed. For DN100 applications, gate valves rated at PN10 are commonly used in water supply systems. The Meson Group (www.mesongroup.com) offers a robust range of gate valves that cater to this specification.
Flat Flanges
Flat flanges are widely used in general piping applications. Made from stainless steel, these flanges have a flat surface that allows for easy installation with gaskets. They are suitable for both low and moderate-pressure applications and are often found in HVAC and plumbing systems. Products can be sourced from suppliers like www.nieruf.com.
Forged Flanges
Forged flanges are made from forged steel, which makes them strong and durable, suitable for high-stress applications. They often feature a thicker design, allowing them to withstand higher pressures. For DN100 applications, forged flanges rated at PN10/16 are essential in industries such as oil and gas. Companies like en.stainlesseurope.com provide various options.
Slip-On Flanges
Slip-on flanges are designed to slide over the pipe and are welded in place. They are easy to install and are frequently used in low-pressure systems. Their versatility makes them a popular choice for a range of applications, including process piping. More options are available at www.piping-world.com.
