Hydraulic Bulkhead union
A bulkhead union is a physical union (a type of hydraulic fitting product) as used in plumbing systems to connect two pipes together allowing the passage of water from one to the other. Hydrofit Engineers offers this type of hydraulic fittings union, which is a deferred type union that is generally used if one pipe or hose that must be connected is on side of wall or barrier and other pipe/hose is from another side. The bulkhead union permits a fluid to pass through the wall or barrier and seal around it.
It is composed of 2 halves that are bolted together by a flange. The flange is usually metallic and adapted to sealingly connect the ends of the first and second union members. The two connections of the union are respectively attached to one pipe or hose that must be connected. The union is then connected to the wall or barrier, with one portion of the union disposed on each side of the wall or barrier.
Key Features of Bulkhead Union
Hydraulic bulkhead union, what makes it special One of the important points about a hydraulic bulkhead union is that even when the pipes/hoses are under a lot of pressure, they still give you a non-leaking connection. The flanged design and use of quality seals help ensure that no fluid leaks out of the union, maintaining a tight seal.
Another positive to this combination is their ruggedness. The above unions find great utility particularly where corrosive or abrasive fluids are involved since the union must be capable of resisting such exposure for long periods of time. Furthermore, the union must be able to resist high temperature and pressure without being destroyed or immobilized.
Types of Bulkhead Union
You’ll find a variety of options for hydraulic bulkhead unions, which are designed to meet the needs of a range of different applications. Size of pipes/hoses and the kind of fluid that passes through; operating parameters are the factors when considering a bulkhead Union.
Threaded Bulkhead: A popular form of hydraulic bulkhead union is the threaded union. This union is intended to be screwed onto the pipes, or hoses that you want to connect together and stay connected so that it will not leak. Threaded unions are common when working with smaller pipes or hoses and not receiving heavily corrosive or abrasive fluids.
Flanged Bulkhead: A flanged union is also another popular type of hydraulic bulkhead union. This kind of union is secured with a bolted flange and prevents the fluids from leaking out of the hub. The name flanged union appears more commonly when the pipes or hoses are larger and the fluid being transferred is toxic, caustic or abrasive.
Compression Bulkhead: Compression fitting union: This is the third category of a hydraulic bulkhead union. This union is joined using a compression fitting to connect the pipes or hoses, ensuring that it remains leak free. Compression fitting unions are often employed in systems where relatively small pipes or hoses are used and the fluid being transferred is not too corrosive or abrasive.
In summary, it is evident that hydraulic bulkhead unions and couplings have a significant role to play in fluid transfer. In use, they enable pipes or hoses located on either side of a wall or barrier to be intercoupled such that fluid may be conveyed between them without leakage. When choosing a hydraulic bulkhead union, consider factors such as the size of the pipes or hoses that are being connected, the type of fluid requiring transfer and operating conditions to ensure that it can source what you need in your application.
