T/WZBF 038-2023 Ventilation leakage detection technical requirements for valves
Abstract
Main technical content: This standard specifies the basic requirements for the leakage detection technology of valves, including inspection, testing, test classification and grade identification, implementation of control, marking, valve certificates of conformity, re-testing, and the leakage measurement method using the suction method. It is applicable to valves with leakage requirements that operate at temperatures ranging from -29°C to 538°C, with a nominal size of ≤ DN600 and a nominal pressure of ≤ PN250 or CLASS 1500.
