Fittings and Flanges Blind Flange Pipe Fittings Pipe Flange Blind Carbon Steel / Stainless Steel / Cu Ni Flange
Pipe flanges are protruding rims, edges, ribs, or collars used to make a connection between two pipes or between apipeand any type of fitting or equipment component. Pipe flanges are used for dismantling piping systems, temporary or mobile installations, transitions between dissimilar materials, and connections in environments not conducive to solvent cementingA.
Blind flange is used to close ends of piping systems. It is a kind of round plate with no center hold but with all the proper bolt holes. This blind flange is available in various sizes and materials and is used to provide positive closer on the ends of pipes, valves or equipment nozzles. This flange helps in easy access to a line once it has been sealed. The blind flange is sometimes custom made or machined to accept a nominal sized pipe to which reduction is being made. This reduction can be a threaded reduction or welded reduction.

| Type | Pressure Capacity | Pipe Sizes | Applications / Advantages |
| Blind | Very high | All | Closing pipes, flow pressure testing |
| Lap joint | Low | All | Systems requiring frequent disassembly |
| Slip-on | Low | All | Low installation cost, simple assembly |
| Socket weld | High | Small | Smooth bore for better fluid flow |
| Threaded | Low | Small | Attachment without welding |
| Welding neck | High | All | High pressures and extreme temperatures |
Features :
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.
Blind flanges are made to fit standard pipes in all sizes.
Application: Due to its good comprehensive performance, flange is widely used in basic projects such as chemicals, construction, water supply, drainage, petroleum, heavy and heavy industries, refrigeration, hygiene, water heating, fire protection, electricity, aerospace, and shipbuilding.
