Что такое pup-piece ?

[tl_canella]

Добрый день! Пожалуйста, помогите разобраться, что такео pup-piece в следующем контексте
In the event that the pipeline overlap is insufficient at the tie-in point, a pup piece will be installed. The pup piece length will not be less than one diameter (1.0 D) of the steel pipe.

Заранее спасибо! =))

This short gap is where a piece of pipe must be placed (cut, beveled, fitted and welded) to connect the two fittings that don't touch. The short piece of pipe is called a "Pup" piece. The piece of pipe or "Pup" can be pretty much any length however when it gets to be around a foot in length it is no longer called a "Pup". A long piece of pipe is just a piece of pipe. The really short ones are called a "Pup".
