Product Description

Products Details

Grooved split flange is a type of flange used in piping systems that utilizes grooves for quick and safe connections. The grooved design is easy to install and remove, making it a popular choice for connecting pipes, valves and other components across industries. The split flange design allows the flange to be installed or removed without disassembling the entire piping system.

ANSI Class 125 and 150 cover pressure ratings for flanges, valves, and fittings. ANSI Class 125 flanges are designed for low pressure applications, while ANSI Class 150 flanges are suitable for high pressure applications. Specific standards for grooved flanges may vary, and you should refer to the manufacturer’s documentation and industry standards.

When dealing with grooved flanges, you may encounter standards from the following organizations:

American National Standards Institute (ANSI): ANSI sets standards for all aspects of piping systems, including flanges.

American Society of Mechanical Engineers (ASME): ASME standards, such as ASME B16.1 and ASME B16.5, cover flanges and flange accessories.

International Organization for Standardization (ISO): ISO standards may also include flange specifications.

Manufacturer’s Specifications: It is critical to refer to the specific documentation provided by the manufacturer of the grooved split flange. Manufacturers often provide detailed information about design, materials, and usage guidelines.

Because standards and product specifications may continue to evolve, it is recommended to review the latest documentation, contact manufacturers, and refer to the latest industry standards to ensure accurate and up-to-date information.
