“ For the upgrade project of our refining unit at the Houston plant, we chose Yuling’s shell and tube heat exchangers. They not only comply with China’s GB151 standard but also perfectly meet the ASME process requirements in the US. Under the high-temperature crude oil heat transfer condition, the equipment operated continuously for 12 months without failure, and its efficiency was 10% higher than that of the previous supplier. What’s more surprising is that Yuling’s team provided a remote solution within 2 hours for cross-timezone technical questions, completely changing our perception of the service efficiency of Chinese suppliers. ”

“ As a European refrigeration equipment integrator, we have extremely high requirements for the precision and compliance of heat exchangers. Yuling’s plate heat exchangers (compliant with NB/T47004 standard) not only passed ISO 9001 certification but also adapted to the European EN 13445 pressure vessel specification. For our miniaturized refrigeration unit needs, their technical team completed the customized design within 3 weeks. The heat transfer uniformity and energy consumption performance of the final equipment fully meet German industrial standards. ”

“ Our ship project required air-cooled heat exchangers adapted to the high-salt marine environment. Yuling’s products (compliant with GB/T15386 standard) not only met the corrosion resistance requirements but also completed delivery 2 weeks in advance—which was critical to our ship schedule. After commissioning, the equipment operated stably under high-temperature conditions in tropical waters. Later, Yuling also arranged technicians to provide on-site maintenance guidance at the Singapore port, and the service professionalism was no less than that of local suppliers. ”
