From March 11 to 14, 2024, an audit team consisting of four auditors from Rhyne Technology (Shanghai) Co., Ltd. conducted an on-site audit of the company's quality, environmental, and occupational health and safety management systems. This audit was a recertification audit of the management systems. Through the four-day review, the evaluation team of experts gave full recognition to the company's production site management and service site management levels, and the company successfully passed the 2024 management system recertification audit.
On the morning of March 11, the first meeting was attended by the company's management representatives Gu Wenyong, Deputy General Manager Jiang Wei, Chief Engineer Zheng Anli, and managers of various departments, along with experts from the three-system review team.

During this certification audit, the audit team also conducted an on-site review of the service situation of the Terrence after-sales service team.
On the morning of March 14, Fang Wei, the manager of the after-sales service department, led an after-sales service team composed of three after-sales engineers to the user's site to replace the regulator parts.
After entering the site, the service team first observed the surrounding situation, and Manager Fang assigned work tasks and safety precautions.

Before formally entering the work area, first pull up the warning line, open the pressure regulation box cabinet door for ventilation, and check for any gas leaks;

The after-sales service engineer diagnosed the fault on-site, initially determining it to be an issue with the regulator valve, and removed it. After comparing the old and new parts and obtaining the customer's approval, it was replaced.

During the maintenance of the equipment, to ensure the safety of personnel, one of the after-sales engineers continuously performs safety supervision, checking for gas leaks around the equipment.

After the equipment maintenance is completed, organize the site and keep the equipment tidy. After a series of tasks are completed, fill out the maintenance record form, have it confirmed by the customer, and invite the customer to evaluate the service team's service.

To prevent risks before they 'ignite,' the company will strictly adhere to all standards in research and development, design, and production, provide customers with safe and reliable products, and follow operational protocols during on-site services to ensure efficient and safe service.
