Introduction of Class 300 Weld Neck Flange
Flange is a connecting fitting commonly used to join pipes or pipe components together or to secure equipment to a surface. Flanges can typically be round or square and are used in various industrial applications.
Class 300 weld neck flange is recognized for its long-tapered hub that provides mechanical strength. Weld neck flanges are high integrity flanges and are available in all sizes, all common face types (flat, raised, RTJ), and all classes.
Class 300 weld neck flanges are used in severe and critical conditions. Some of these include high pressure, wide fluctuations in temperature and pressure, high temperature, fluids that are volatile and hazardous, and temperatures in the sub-zero range.

ASTM A105 Class 300 Weld Neck Flange
ASTM A105 is a commonly used standard developed by the American Society for Testing and Materials (ASTM), specifically for the manufacture of carbon steel forgings. This standard specifies the chemical composition, mechanical properties, and other related requirements of carbon steel forgings to ensure their quality and reliability. Class 300 refers to the pressure rating of the flange.
ASTM A105 forgings are mainly made of carbon structural steel, and their chemical
