Aggregate 123 items were finished and 807 pieces of equipment were maintained. All the quality inspection and control process was well executed and all the maintenance items were checked , tested, and accepted to be qualified, except some that didn’t have the testing condition ready. The operation safety and technical indicators of all the tested equipment reached or exceeded the expectation.
The periodical maintenance job had the Hanas Group delicacy management philosophy as the guiding though.
