BLIND FLANGE FOR PIPING HYDRAULIC TEST

摘要

PURPOSE: A blind flange for testing the hydraulic pressure of a pipe is provided to install the blind flange performing a function of a vent hole in a facility where constructing the vent hole is impossible, thereby smoothly performing a hydraulic test. CONSTITUTION: A blind flange for testing the hydraulic pressure of a pipe comprises a body(10) and a vent hole(13). The body includes a pipe guide protrusion(11), and a plurality of bolt coupling holes(12) is formed radically along the circumference of the body. The bent hole is formed for ventilation or drainage at a position separated from the center of the body.
