لوله تیوب خالی است كه برای انتقال محصولات و همچنین فشار به كار می رود.
محصولات عبارتند از سیال، گاز فاضلاب، پودرها، دانه های ریز و یا خیلی ریز و یا خیلی چیزهای دیگر.
فشار نیز قدرت هیدرولیكی است ما معمولا هنگامی به تیوب لوله اتلاق می كنیم كه برای خطوط لوله بكار می رود.
اما این تعریف به طور كلی هر چیزی را برای كاربرد مشابه با آنچه گفته شد در بر می گیرد.
