Haihao Group supplies ASME B16.5 threaded reducing flanges for Singapore client

What is a Threaded Reducing Flange?

A threaded reducing flange is a specialized type of pipe flange designed for connecting pipes of different diameters. It features a threaded bore, allowing for easy assembly without the need for welding. This type of flange is commonly used in low-pressure applications where welding is impractical or undesirable, such as in gas and water distribution systems.

Differences Between Reducing Flanges and Standard Flanges

Functionality:

Standard flanges connect pipes of the same diameter.

Reducing flanges allow for smooth transitions between pipes of different sizes, reducing turbulence and pressure loss.

Design:

Reducing flanges have an asymmetrical design with different inner and outer diameters.

Standard flanges have a uniform bore and bolt pattern.

Application:

Reducing flanges are ideal for pipeline systems requiring step-down connections.

Standard flanges are used in pipelines where diameter changes are not required.

Haihao Group’s ASME B16.5 Threaded Reducing Flange Production

Haihao Group recently completed the production of ASME B16.5 threaded reducing flanges for a client in Singapore. These flanges were manufactured from ASTM A105N carbon steel, ensuring high strength and durability for industrial applications.

Flange Specifications

The supplied flanges include the following sizes and pressure ratings:

1.5″ x 0.5″ 150#

0.75″ x 0.5″ 150#

2″ x 0.75″ 300#

1″ x 0.5″ 150#

These flanges meet ASME B16.5 standards, which specify dimensional requirements, pressure ratings, and material properties for pipe flanges and fittings.

Quality Control and Inspection

Haihao Group adheres to stringent quality control measures, ensuring each flange meets international standards. Our inspection process includes:

Dimensional Inspection – Measuring flange thickness, bore diameter, and bolt hole alignment.

Material Testing – Verifying chemical composition and mechanical properties of ASTM A105N steel.

Thread Inspection – Ensuring precise threading for a secure and leak-free connection.
