Weld Neck flange (CL-900-RTJ-2″)

Weld Neck flange (WN-RTJ), Class 900, Size 2 inches, Thickness: 80 inches, Production standard: ASME B16.5

Weld Neck flange (CL-900-RTJ-2″) is a type of 2 inch diameter flange made for pipes with 2 inch inside diameter. weld neck flanges with Class 900 are designed to withstand higher-pressure compared to lower class flanges and are usually used in applications that require high-pressure resistance. Class 900 for Weld Neck flange is equal to the nominal pressure of 150 bar. Also, the maximum pressure tolerance according to this class is 255 psi and the maximum pressure is 2220 psi.


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

2- Bore: Weld Neck flange (CL-900-RTJ-2″) has a central hole to connect to the pipe.

Pressure and temperature: This flange can withstand 2220 psi pressure if the temperature is less than 37 degrees Celsius, and if the temperature is around 537 degrees Celsius, the highest pressure that can be tolerated is 225 psi.

3- Materials: carbon steel, stainless steel and alloy

4- Application: oil and gas, petrochemical, power plant and chemical industries

When selecting a flange, including a weld neck flange with Class 900, factors such as pipe size, material compatibility, temperature and pressure requirements must be considered. To ensure that the flange is suitable for your intended application, consult with experts and engineers in the field or relevant industry standards and guidelines such as ASME B16.5 are necessary.
