METHOD FOR CHECKING LEAKAGE PORTION OF CONDENSER AND HEAT EXCHANGER TUBE

摘要

PURPOSE: A method for checking leakage portion is provided to check the leakage portion in an accurate and rapid manner regardless of the thickness of tube and foreign substances. CONSTITUTION: A method comprises a first step of depositing a foam(20) to both sides of a plurality of tube sheets of a condenser or heat exchanger, through a foam depositing device(10); and a second step of checking the portion where the deposit foam is depressed, by applying vacuum into the condenser. The foam depositing device has a flexible pipe(40) arranged at a foam bomb(30) which contains the foam, and an extended pipe(50) is connected to the flexible pipe. The extended pipe has a foam deposition adaptor(60) arranged at an end of the extended pipe, and the foam deposition adaptor is formed into a dual structure including an inner pipe(61) having holes(62) for uniformly discharging foam, and an outer pipe(63) for discharging foam through an open surface(64).
