NDL Black Nipple 1/2" X 36" BPF113BS-D36

The NDL BPF113BS-D36 is a 1/2 inch by 36 inch black iron pipe nipple with threaded ends for gas piping and threaded pipe assemblies.

Sizing a gas piping system is a calculation rather than a matter of matching the appliance connection. The pipe must deliver the required volume of gas at adequate pressure to every appliance, with all of them operating simultaneously, and the required size depends on the total connected load, the length of the run, the number of fittings, the gas type, and the allowable pressure drop.

Undersized gas piping produces symptoms that are frequently misdiagnosed. Appliances operate acceptably alone but perform poorly when several run together, burners may not reach full input, and a furnace may short cycle or fail to maintain its firing rate. The technician arrives to find the appliance apparently at fault when the piping is the constraint.

Manufacturers and codes publish sizing tables that give capacity against pipe size and equivalent length, and working through the table is the correct approach when adding an appliance to an existing system.

Adding a load to piping sized for the original appliances is a common way to create this problem.

Confirm pipe size, length, and thread specification against the design. Support piping adequately, protect it from mechanical damage, and pressure test and leak test the installation before returning any appliance to service.
