Manufacturing
The heavy equipment assembly workshop is equipped with over 230 units of various machinery, including large lifting equipment, underwater plasma cutting systems, and automated welding machines. The facility features a 160-ton heavy-duty crane and a sunken-style dock adjacent to the Deqing Branch of the Beijing-Hangzhou Grand Canal. This allows oversized cargoes measuring up to 50 meters in length, 10 meters in width, 7.5 meters in height, and weighing up to 500 tons to be shipped directly via the canal to major ports such as Shanghai, Ningbo, and Zhoushan.
The company employs senior and mid-level professionals specializing in cryogenics, low-temperature engineering, chemical machinery, welding, nondestructive testing, mechanical manufacturing, and instrumentation/electrical control. We maintain long-term collaborations with multiple science and engineering universities, including Zhejiang University and Lanzhou University of Technology. We are a specialized manufacturer of cryogenic air separation equipment, low-temperature liquid storage and vaporization systems, LNG liquefaction plants, and chemical processing equipment. Our company features advanced manufacturing capabilities and comprehensive quality assurance systems. Our facilities include domestically leading automated submerged arc welding machines, inverter welding machines, CNC milling equipment for tower internals, heavy lifting systems, cutting and rolling machinery, advanced sandblasting systems, and large annealing furnaces. Additionally, we are equipped with helium mass spectrometers for leak detection, the non-destructive testing lab, mechanical properties testing lab, and chemical analysis lab to ensure rigorous inspection and validation.
