Blind Flanges

Image
These Flanges are used as a termination point to a piping system. Blind-Flanges have a blank surface with bolt point to fit a pipe. Flange JPI Class 150 BL RF A20 B3 A Blind flange is round plate which has all of the relevant boltholes but no center hole, and because of this feature this flange is used to close off the ends of a piping systems and pressure vessel openings. It also permits easy access to the interior of a line or vessel once it has been sealed and must be reopened. The 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. Blind Flang

Welding neck flanges

The Welding neck flanges 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 becuase of its inherent structural value. It is expensive because of the design.

The types of pipe flange

Image
A pipe flange is disc, collar or ring that attaches to pipe with the purpose of providing increased support for strength, blocking off a pipeline or implementing the attachment of more items. Pipe flanges are usually welded or screwed to the pipe end and are connected with bolts. A gasket is inserted between the two mating flanges to provide a tighter seal. Pipe flanges are either custom with dimensions provided by the customer or they are manufactured according to published specifications. Several organizations and associations have published specifications that provide dimensional information as well as pressure specifications at different temperatures. Sunny Steel manufactures custom flanges and stocks 6 basic types of pipe flanges. Although, these are the 6 most common types of pipe flanges, Sunny Steel is a custom flange manufacturer as well and is able to create just about any type of flange necessary for your requirements.
