Blind Flanges
Blind flanges are sometimes supplied with NPT fittings which allow pressure test connections to be fitted.
They are used to blank off the ends of pipe.
They are also used to blank off the ends of valves and pressure vessel opening.
Considering factors like internal pressure and bolt loading, blind flanges, especially in the larger sizes, are the most highly stressed of all types of flanges.
Since the maximum stresses in a blind flange are bending stresses at the center, they can safely be allowed to be higher than in other types of flanges.
Reducing Flanges
Reducing flanges are designed for use in changing diameters in a piping system. A reducing flange comprises a flange with one specified diameter having a bore of a different and smaller, diameter. Except for the bore and hub dimensions, the reducing flange will have dimensions of the larger pipe size. These flanges are used at the outlet side of the expansion joint to increase the size of the flange. This is considered to be an economical method to make a transition in size.
Materials: Carbon Steel, Stainless Steel Grades, Duplex Steel.
Size: 0.5"NB TO 48"NB.
Slip-on Flanges
The slip-on flanges have a low hub because the pipe slips into the flange prior to welding. It is welded both inside and out to provide sufficient strength and prevent leakage. They are ideal for low pressure applications.
Weld Neck Flanges
Weld Neck Flanges are confined to special applications. Their chief merit lies in the fact that they can be assembled without welding this explains their use in extremely high pressure services, particularly at or near atmospheric temperature, when alloy steel is essential for strength and where the necessary post weld heat treatment is impractical.
