Weldneck Flange (CL-150-2″)

Weldneck flange (RF), Class 150, Dimensions 2 inches, Standard ASME B16.47 (A182)

The weldneck flange (CL-150-2″) has a neck, meaning it has a long, tapered hub with a circular bore. This flange is welded to the pipe and creates a tight and rigid connection. Welded throat flanges are known for their high strength and reliability, which makes them suitable for high-pressure applications, such as in the oil and gas or petrochemical industries.



1- Neck: The weld neck flange has a long neck or throat to connect to the pipe through welding.

2- Resistance: the weld neck flange (CL-150-2″) has high strength against pressure and heat due to the working pressure of 150.

3- Bore: Weldneck flange (Class 150- 2 inches) has a central hole (Bore) to connect to the pipe.

4. Materials: carbon steel, stainless steel and alloy

5- Application: It is used in various industries including oil and gas, petrochemical, power plant and chemical industries.

When specifying a weld neck flange, it is important to consider other factors such as: pressure rating (class), material compatibility, and any industry-specific standards or regulations that apply to your application. Because class 150 in the weldneck flange indicates an allowable working pressure between 20 to 285 psi. These flanges are suitable for medium and medium-heavy pressure applications. Weld neck flanges are available in various sizes and pressure ratings to suit various pipe requirements.


It must be ensured that the weld neck flange selected meets the specific requirements of your piping system. It also meets the relevant standards and specifications. Consulting with a qualified engineer or referring to industry standards such as ASME B16.5 can help in choosing the right flange.
