The status and defects of the pressure piping of ammonia refrigeration is studied. Based on the inspection of the pressure piping of dozens of refrigeration companies, a lot of problems and defects are found and classified. The main reasons are that the blueprints from the unqualified companies are used and the construction regulations are violated. So the advices on the construction of the pressure piping and the processing method of the defects are given.
