High Quality Carbon Steel Flange in China
The welding neck flange is normally referred to as the "high hub" Flange. It is designed to transfer stresses to the pipe, thereby reducing high stress
Concentrations at the base of the Flange. The welding neck flange
Is the best designed butt-welded flange of those currently
Available because of its inherent structural value. It is expensive
Because of the design.
Threaded (Screwed) Flanges:
The threaded flange is similar to the slip-on flange, but the bore is threaded. Its chief merit is that it can be assembled without welding,
Explaining its use in low pressure services at ordinary atmospheric
Temperatures and in highly explosive areas where welding create a hazard
Process: Free Forging, Mould Forging, Upset Forging.
