ASME B16.47 Series B A105n Lined Carbon Steel Flanges CLASS 900
ASME B16.47 Series B CLASS 900 A105n Carbon steel lined flange
Description
Carbon steel lined flange are used for pipe isolation, and are mostly produced by welding or rolling processes. The flanges produced by these two processes have certain restrictions on bearing pressure. When the working pressure reaches a certain limit, deformation or other faults will occur. Therefore, rolling and welding flanges can only work in an environment with relatively small pressure.

Characteristic
Carbon steel lined flange can be made into smooth, concave convex and tenon groove sealing surfaces. Smooth butt welding flange is widely used. It is mainly used in welding technology. It has good application characteristics and performance, reasonable structure, large strength and stiffness and good sealing.
Application
Carbon steel lined flange is mainly used in oil and gas pipeline engineering, natural gas pipeline engineering, chemical plant, power plant, shipyard, pharmacy, dairy, beer, beverage, water conservancy, etc.
