Abstract: Production equipment, technical parameters and process of viscoelastic anti-corrosion materials developed independently by the Pipeline Research Institute of CNPC are described, and a tracking test is conducted for cathode disbonding at 70 ℃, 120 d hot water soaking, peel strength at 23 ℃, shear strength, insulation resistivity, density, impact strength, water absorption and other properties of the material inaccordance with relevant standards such as GB/T4472-84, DIN30670-91, SY/T0414-2007, ISO21809-2008 and GB/T23257-2009. The results show that all performance indexes are in line with the relevant standards. The material with good corrosion resistance has been widely used in the field coating for welded joint, valve chambers and stations in the 2nd West-to-East Gas Pipeline, which basically ensure the safeoperation of the Pipeline.
