Steel nipple refers to a seamless steel pipe or a welded steel pipe made of carbon steel pipe and cuts into a short galvanizing process after an externally threaded stud made in processing. Generally, the welded nipple fitting includes two kinds of hot-dip galvanized and electro-galvanized, having a rust and corrosion advantage.
