In order to simplify the coating process and reduce the cost of field joints，the applicability of spraying polyurea in field joints was studied in the paper. The field joints anti-corrosive coating of subsea pipeline were prepared by using polyurea from A domestic company and B foreign company. A systematic and comprehensive analysis of the coatingproperties was studied. The results showed that both polyurea coating had excellent mechanical properties，electrical insulation，water resistence and tensile strength retentionafter heat treatment. But the interface bonding between them and the substrate failed aftercathodic stripping，and the tensile strength retention rate of the two coatings after salt，alkali and acid treatment was poor.
