Description of ASME B16.5 Threaded Flanges:
ASME B16.5 is a standard created by the American Society of Mechanical Engineers (ASME) that specifies the dimensions, materials, and performance requirements for threaded flanges. Threaded flanges are a type of flange used to join pipes or fittings with external threads.
Here is a description of ASME B16.5 threaded flanges:
Design and Dimensions: ASME B16.5 threaded flanges are designed to have a standard pipe thread (NPT) conforming to ANSI/ASME B1.20.1. The flanges have a cylindrical shape with a raised face or a ring-type joint face. The standard covers flanges ranging from 1/2 inch to 24 inches in size.
Pressure Ratings: The ASME B16.5 standard provides pressure-temperature ratings for threaded flanges. These ratings indicate the maximum allowable pressure at a given temperature. The pressure ratings range from 150 pounds per square inch (psi) to 2500 psi.
Materials: The standard specifies the materials for threaded flanges based on their application and compatibility with the fluid being conveyed. Common materials used for ASME B16.5 threaded flanges include carbon steel, stainless steel, alloy steel, and non-ferrous metals such as bronze or brass.
Face Types: ASME B16.5 threaded flanges come with two face types: raised face (RF) and ring-type joint (RTJ). The raised face flange has a flat gasket sealing surface and is suitable for most general-purpose applications. The ring-type joint face flange features a groove machined into its face and uses a metal ring gasket for sealing. RTJ flanges are commonly used in high-pressure and high-temperature applications.
Marking and Identification: ASME B16.5 threaded flanges are marked with relevant information such as flange size, pressure rating, material specification, and manufacturer's identification. This marking helps in proper identification and ensures that the flanges meet the required standards.
Installation and Assembly: Threaded flanges are assembled by screwing the male thread of the flange into the female thread of the connecting pipe or fitting. Proper tightening techniques and the use of suitable thread sealants or tape are essential to ensure a leak-free joint.
ASME B16.5 threaded flanges are widely used in various industries, including oil and gas, petrochemical, chemical, power generation, and water treatment. They provide a reliable and convenient method for joining pipes and fittings with threaded connections, allowing for easy installation, maintenance, and disassembly.

The Pressure-temperature Rating of ASME B16.5 Threaded Flanges:
The pressure-temperature ratings specified in ASME B16.5 for threaded flanges provide guidance on the maximum allowable pressure at various temperatures. These ratings are crucial for ensuring the safe and reliable operation of threaded flange connections. Here are some key points regarding pressure-temperature ratings:
Pressure Classes: ASME B16.5 threaded flanges are assigned pressure classes ranging from 150 to 2500. Each pressure class corresponds to a specific maximum pressure at a given temperature. The pressure classes are designated as Class 150, 300, 400, 600, 900, 1500, and 2500.
Maximum Pressure: The maximum allowable pressure for threaded flanges varies depending on the flange size, pressure class, and temperature. The higher the pressure class, the higher the maximum pressure the flange can withstand. For example, a Class 150 threaded flange has a lower maximum pressure compared to a Class 300 flange.
Temperature Range: ASME B16.5 provides temperature limitations for threaded flanges based on the material used. These limitations help prevent thermal stress or material failure. The temperature range typically spans from -20°F (-29°C) to 1000°F (538°C) for standard carbon and low-alloy steel flanges. Higher temperature ranges are available for specific materials like stainless steel or alloy steel.
Derating Factors: At elevated temperatures, the maximum allowable pressure for threaded flanges may need to be reduced due to the decrease in material strength and the potential for thermal expansion. ASME B16.5 provides derating factors that should be applied to the pressure ratings to account for these effects. The derating factors are specified based on the temperature range and the material of the flange.
Flange Material Selection: The pressure-temperature ratings also depend on the material of the threaded flange. Different materials have different mechanical properties and temperature limits. It is essential to select a flange material that is compatible with the system's fluid, pressure, and temperature requirements.
