摘要：
Method to make a tubular element (10) to transfer abrasive materials such as concrete, inert materials or suchlike, wherein the tubular element (10) comprises an external tubular component (11) made of steel and an internal tubular component (12), coaxial to the external tubular component (11). The internal tubular component (12) is made of chromium carbide, or other similar material resistant to wear.
