The Wuhan Donghai-manufactured coiled-tube heat exchanger from AP Company successfully passed the factory acceptance test.

On December 16–17, 2020, Air Products (China) Investment Co., Ltd. (hereafter referred to as AP), along with a five-member delegation from Jiangsu Debang Xinghua Chemical Technology Co., Ltd. (hereafter referred to as Debang), conducted inspection witnessing and final product acceptance for the six wound-tube heat exchangers manufactured by our company for Debang’s 350,000-ton-per-year ammonia synthesis project featuring low-temperature methanol washing technology.

The users reviewed documents related to the design, manufacturing processes, and inspection records of the six coil-type heat exchangers. They exchanged ideas and discussed the advanced features and reliability of the key machining processes used during manufacturing. Additionally, the team fully endorsed the latest seismic-resistant technology recently adopted by Wuhan Donghai. The acceptance group conducted on-site inspections and observed selected inspection milestones as outlined in the ITP plan, verifying the associated data and records. They also strengthened inspection requirements and increased the sampling rate for critical equipment components and weld seams.
After two days of inspection, verification, and fruitful exchanges, the acceptance team concluded that the product quality of Jiangsu Debang Project is excellent. Meanwhile, Wuhan Donghai is advised to continue diligently preparing for all necessary steps prior to the upcoming shipment. During this period, representatives from AP Company also engaged in an extensive discussion with our team regarding the R&D history, design philosophy, calculation methods, and manufacturing technology development of our company’s wound-tube heat exchangers.
