ANSI B16.5 RAISED FACE SLIP-ON Flange

General Introduction
ANSI B16.5 is a widely used standard in the piping industry in the United States and many other parts of the world. It specifies the dimensions, tolerances, materials, and pressure - temperature ratings for raised face slip-on flanges and other types of pipe flanges. A raised face slip-on flange is a key component in piping systems, designed to connect pipes, valves, pumps, and other equipment, allowing for easy assembly, disassembly, and maintenance.
Design and Structure
Raised Face: The raised face of the flange provides a better sealing surface compared to a flat face. It has a raised circular area in the center that mates with the gasket to form a tight seal. This design helps to prevent leakage and is suitable for applications where a higher level of sealing integrity is required.
Slip-On Design: The slip-on flange is designed to slide over the end of the pipe. It has an inside diameter that is slightly larger than the outside diameter of the pipe. Once the flange is slipped onto the pipe, it is welded in place. This type of flange is relatively easy to install and is commonly used in low to moderate pressure applications.
Dimensions and Specifications
Diameter: ANSI B16.5 defines standard sizes for flanges, ranging from 1/2 inch to 24 inches.
Materials
ANSI B16.5 raised face slip-on flanges are available in a variety of materials, including carbon steel, stainless steel, alloy steel, and other materials depending on the specific application requirements. Carbon steel flanges are commonly used for general-purpose applications where corrosion resistance is not a major concern. Stainless steel flanges are preferred in applications where high corrosion resistance is required, such as in the chemical and food processing industries.
Applications
ANSI B16.5 raised face slip-on flanges are widely used in various industries, including oil and gas, chemical processing, power generation, water treatment, and many others. They are used in pipelines that transport fluids such as oil, gas, water, chemicals, and steam. In the oil and gas industry, they are used in refineries, pipelines, and offshore platforms. In the chemical industry, they are used in chemical plants for the transportation of various chemical substances.
