A bypass connection, often referred to as a "Flow Through Connection," is a pipe or passage that runs directly through an object, typically a plug or valve, from one end to the other.
This direct passage allows for flow to continue uninterrupted, even when the primary function of the object (like a plug blocking a pipe) is active. Think of it as a detour built right into the object itself.
Here's a more detailed breakdown:
-
Function: The primary function of a bypass connection is to provide an alternate route for fluids (liquids or gases) when the normal pathway is blocked or restricted.
-
Applications: Common uses include:
- Filling piping for testing: As the reference mentioned, a bypass connection can be used to fill a pipeline with air or water for pressure testing purposes, even with a plug in place.
- Pressure equalization: Bypasses can equalize pressure on either side of a valve or plug, making it easier to open or remove.
- Maintaining flow during maintenance: In some systems, a bypass allows flow to continue around a component being serviced or repaired, preventing complete shutdown.
- Safety relief: Bypasses can be incorporated into safety systems to relieve excess pressure and prevent damage.
-
Example: Imagine a pipeline needs to be tested for leaks. A plug is inserted to isolate a section. A bypass connection built into the plug allows water to be pumped into that isolated section for the test, even though the plug is blocking the main flow path.
-
Synonyms: Besides "Flow Through Connection," you might also hear terms like "bypass line" or "bypass circuit," although these often refer to more complex systems rather than a simple passage through an object.
In summary, a bypass connection is a simple yet effective way to provide an alternate flow path, offering flexibility and utility in various piping and fluid handling systems.
