The threaded nipples are made of black tube electroplated or hot-dip galvanized steel pipes. They are used to connect two internally threaded galvanized steel pipes and fittings. The nipples are wrapped by internal threaded fittings. The tight nipples have no threadless areas and are almost not exposed. Threaded nipples are used in commercial and industrial environments to transmit water, oil, gas or air through pipe systems. Threaded nipples are a quick and economical component that can be easily added to these pipe systems. Closed pipe nipples do not require welding, so they can be easily and conveniently installed for daily use.
