Precision rolled tube
              The GRINM has abundant of experiment and theory of tube rolling technology. At present there are LD80, LD60, LD30, LD15, LD8, and other specifications of the precision rolling mill. The 5 series aluminum precision thin-walled tubes which can be flared and curved forming are produced. The diameter is 6 ~ 150mm. The wall thickness is 0.3 ~ 2.5mm.The accuracy of wall thickness and other dimension is more stringent than the national standard of high precision level. They are used for aerospace. In addition, precision titanium alloy thin-walled tubes are produced. The diameter is 2~ 120mm. The wall thickness is 0. 1~ 3mm. They are used for aviation fuel pipeline.
