Stainless steel pipe is a kind of hollow long round steel, which is mainly used in industrial transportation pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and so on. Lisaks, kui painde- ja väändetugevus on samad, on kaal kergem, mistõttu kasutatakse seda laialdaselt ka mehaaniliste osade ja insener-konstruktsioonide valmistamisel.
