Product Description

.ASME B16 47 SER A WN RF 42IN THK=0 75IN CL300# ASTM A105

The ASME B16.47 Series A standard covers large diameter steel flanges from 26 inches to 60 inches in size. The "WN" stands for "weld neck," and "RF" stands for "raised face." The 42IN refers to the size of the flange, and THK=0.75IN refers to the thickness of the flange. The "CL300#" indicates that the flange is designed to withstand pressure up to 300 pounds per square inch. ASTM A105 is a standard specification for carbon steel forgings for piping applications.

This type of flange is commonly used in high-pressure and high-temperature applications, particularly in the oil, gas, and petrochemical industries. It is important to ensure that the flange material, dimensions, and pressure ratings are suitable for the specific application and operating conditions.
