The expansion Office of Anhui Haoyuan Chemical Group Co., Ltd. is a technical team that dares to fight hard battles and is good at fighting hard battles. All staff work together and strive hard to advance the construction progress of Yingdong Coal-based Industrial Park project, to achieve the first phase of project construction start-up success on schedule, and to create the shortest record of the construction cycle of the same industry and similar projects.

_The whole staff of the Extension Office resolutely practiced the concept of "no safety, everything returns to zero", strictly grasped the safety management of the project, strengthened the safety inspection on the construction site, strictly guarded against "three violations", and eliminated the accident in its infancy. In the early stage of the project, the project personnel carefully demonstrated and studied the technical scheme of the project, and guaranteed the intrinsic safety of the project from the aspects of technology and equipment. During the construction of the project, the project team carefully demonstrates and refines all kinds of operation schemes, and strictly carries out the construction according to the formulated operation schemes, so that all operations can be controlled, safe and orderly, and the progress of the project has never been affected by safety accidents, thus ensuring the implementation of the project as planned.

_During the construction of the project, strict checks are carried out from the material entry inspection, the use of pipeline welding materials, the standard of pipeline groove, the control of welding process to the radiographic inspection after welding completion. The whole process of project participants is supervised, strict quality management system is implemented, supervision units and construction units are well coordinated, and zero tolerance is implemented for the quality problems during construction. If we find quality problems, we should punish them severely and start over again. In the process of project construction, eliminating all kinds of hidden dangers, eliminating the delivery of defective devices to production departments, shouldering the responsibility of expansion personnel, and building first-class devices.

_All the staff of the expansion office strive hard to overcome various unfavorable factors, such as high temperature and severe cold. In order to speed up the construction progress of the project, many comrades often work overtime to catch up with the progress. Many comrades eat and live on the site for a long time, busy in the construction site during the day and meet at night to solve the problems in the construction process. It is the selflessness of all the project personnel that overcomes all kinds of difficulties, guarantees the overall progress of the project and makes the device start successfully at one time.
