Forged Flange Carbon Steel are less carbon-free than molten flanges in general. They are flat, the constructions is fairly lightweight and the molten flange has superior mechanical properties. Improper methods of forging can often result in broad or irregular grains, it is higher to harden cracking and forging than the casting flange
Flange Carbon Steel are used to connect pipes with each others, to valves, to fittings, and to specialty items such as strainers and pressure vessel, a cover plate can be connected to create a blind flange. Flanges are joined by bolting, and sealing is often completed with the use of gaskets or other methods.

TYPE OF FLANGE CARBON STEEL:
1.Welding neck flange.
These Carbon Steel Flanges are popular for their long conical collar with the accompanying wire, their end is welded to the bottom. The tube's inner diameter is similar to that of the flange carbon steel. This feature of wp11 fittings is a segment conduit that is essentially stable, with the little change of creating frictions in the gases or liquids that flow through it. The long arm, and the smooth transformation of the same thickness .
2. SLIDING FLANGES (SLIP-ON).
The tube penetrates the cube of the same in this form of carbon steel flanges without touching the plane of the touch face to which it is connected by means of internal and external welding seams.
Owing to the lower accuracy of the tube duration and better flexibility of place it can be regarded as easier then the neck flange carbon steel. Its mechanical conditions are usually fine for resistance and exhaustion, but much weaker than neck flanges.
3. BLIND FLANGES.
They are designed to cover the ends of the tubing, valves or tube openings, due to various operating pressure. This form of WPHY 42 Fittings is, from a technological point of view, the one that can endure the most extreme working conditions. In Terminals where temperature is a function element or vector or cycling movements, it is advisable to render the closures by coupling neck and blind flange carbon steel.
