Established in the mountain city of Chongqing, China in 2002, ChongQing Orient Mechanical and Electrical Technology Co, LTD (“Orient”) is a comprehensive technology company that specializes in non-destructive testing, corrosion monitoring, maintenance, technical consultation, technical cooperation and delegated sales of special maintenance tools and equipment in petrochemical, electric power and other industries. entity.

We have nearly twenty years of experience in heat exchanger and air cooler tube bundle eddy current and rotary ultrasonic IRIS inspection; furnace tube creep defect inspection and evaluation; urea high-pressure equipment comprehensive corrosion inspection; turbine rotor blade and shroud rivet defect inspection and other aspects.

Our testing technology, testing quality and testing efficiency are highly recognized by customers around China. By developing close and in-depth cooperation with relevant domestic and foreign testing equipment companies, testing and inspection institutes, and scientific research institutions, we strive to provide our users with first-class technology and services.

Orient has a group of highly-competent technical personnel in chemical machinery, corrosion and protection, metal materials, non-destructive testing, computer technology, and automation. More than 80% of our special equipment inspection and testing personnel hold certificates of eddy current intermediate (level II) or even higher level.

The founder of Orient, Mr. Zhou Qingmu, went to Stamicarbon in the Netherlands to receive proprietary technology training in urea equipment corrosion detection, comprehensive defect evaluation and defect repair, and participated in the technical development of “heat exchanger tube exchange technology”, “cleaning technology of urea unit stripper” and “repair technology for corrosion and failure of urea high-pressure equipment”.
