The pipe nipple is a short piece of pipe usually with external/male threads in both ends or in one end for connecting two other pipes or fittings. The threads at two ends can be the same or different types, such as NPT thread to BSP thread nipples are also exist. And the pipe nipple is one of the most popular categories of pipe fittings. Hebei sanvo is one of the quality pipe nipple suppliers and manufacturers in China, exporting various types of pipe nipples. The pipe nipple sizes are American standard 1/8"-8", German standard DN6-DN150, and British standard 1/8"-6", etc; The pipe nipple materials are carbon steel or stainless steel; The surface finish is galvanized or black; The end type is TOE or TBE; The pipe types of pipe nipples are welded pipe or seamless pipe. So, there are carbon steel pipe nipple, stainless steel pipe nipple, galvanized pipe nipple, black pipe nipple, TOE pipe nipple, TBE pipe nipple, welded pipe nipple, and seamless pipe nipple, etc.

You will find the most direct, yet detailed answers to basic questions, you often ask about carbon and stainless steel pipe nipples.
Without further ado, here we go:

What Is A Pipe Nipple?

In plumbing and piping, a nipple is a fitting, consisting of a short piece of pipe, usually provided with a male pipe thread at each end, for connecting two other fittings.

The length of the nipple is usually specified by the overall length with thread. It may have a hexagonal section in the center for a wrench to grasp (sometimes referred to as a "hex nipple"), or it may simply be made from a short piece of pipe (sometimes referred to as a "barrel nipple" or "pipe nipple"). A "close nipple" has no unthreaded area; when screwed tightly between two female fittings, very little of the nipple remains exposed. A close nipple can only be unscrewed by gripping one threaded end with a pipe wrench which will damage the threads and necessitate replacing the nipple, or by using a specialty tool known as a nipple wrench (or known as an internal pipe wrench) which grips the inside of the pipe, leaving the threads undamaged. When the ends are of two different sizes it is called a reducer or unequal nipple.

Threads used on nipples are BSP, BSPT, NPT, NPSM, and Metric.
