Tapoffs

Tap-offs, or tap-off connections, refer to points where a portion of a main line is diverted to feed a secondary line or equipment. The concept is common in fluid handling, electrical power distribution, and even beverage service, and the term implies a branch off a larger system without altering the primary flow.

In piping and fluid systems, a tap-off is a branch taken from a main pipeline. It may be created with a tapping tee, a welded branch, or a clamp-on saddle, and is designed to carry product to meters, tanks, or downstream equipment. Tap-offs must be sized for the expected flow and installed with appropriate isolation valves and pressure-rated fittings. Proper testing and inspection are required to maintain system integrity.

In electrical distribution, a tap-off connection provides a secondary circuit or voltage draw from a primary winding or feeder. This can be seen on distribution transformers with multiple secondary taps or on busbars where a branch feeder is connected. Tap-offs must comply with electrical codes, provide adequate protection, and account for voltage drop and fault clearance.

In the beverage industry, tap-offs describe the points where lines from kegs or tanks connect to taps serving draught beer or other beverages. These systems use sanitary fittings and regulator components to maintain product quality and hygiene.

Safety and standards: tap-offs are subject to industry-specific codes, including pressure, temperature, and cleanliness requirements in fluids, insulation and clearance in electrical systems, and sanitary standards in food and beverage applications.
