The process flow for the 88.9 ×5.49 N801 thermal insulation tubing produced by the 159MPM mill train is introduced. The causes leading to the defects of the thermal insulation tubing and their distribution are analyzed and thus countermeasures for these defects are proposed. After the measures are taken, the yield strength of the tubing is increased from 599.8 MPa to 618.5 MPa while the product percent of pass for the tubing products is improved greatly, reaching to as high as 94.04 percent.
