5.1 Overall normal temperature test
5.1.1 Test conditions
a. · Filtration degree: room temperature
b, medium: diesel
c. Equipment: pressure test pump, test tank, various conversion joints and tools, · general measuring tools, etc., 5.1.2 Test content
. Sealing test: put the assembled products into the test tank with the corresponding inner diameter, pressurize them from the center tube to 15MPa, stabilize the pressure for 5min, and the products without leakage are qualified.
b. Strength test: pressurize the qualified products from the center tube to 20MPa, stabilize the pressure for 5min, and the products without leakage and deformation of the steel body after the test are qualified.
