Development Journey

1982	Chemical packing manufacturer established
1992	Securing administrative licenses for the design and manufacturing of chemical equipment marks a successful corporate transformation.
2005	Establishing a large-scale fixed-bed reactor production line for the chlor-alkali industry
2007	Wuhan Donghai Petrochemical Heavy Equipment Co., Ltd. Wuhan Base Completed
2008	Obtain an A1/A2 Special Equipment Manufacturing License Establish a Process Equipment Engineering Company to deliver a comprehensive engineering R&D service platform encompassing modular engineering design, equipment manufacturing, project management, and technical consulting—primarily focused on melamine technology for small- and medium-sized chemical units.
2009	Obtained the ISO9001-2008 Quality Management System Certification. Obtaining the ASME U Stamp Authorization Certificate Our company has successfully manufactured an 8,200 mm diameter equipment unit for the 600,000-ton-per-year methanol project.
2010	The municipal sludge treatment technology and complete equipment project has been approved by the National Science and Technology Innovation Fund. The high-pressure heat exchanger for the 30,000-ton-per-year diesel hydroprocessing unit has successfully passed acceptance testing (design pressure: 12.2 MPa, material: 12Cr2Mo1R + 0Cr18Ni10Ti).
2011	A -101°C-grade alloy low-temperature steel pressure vessel has passed the provincial and ministerial-level assessment of new technologies and innovative products.
2012	Obtain an A1/A2 Special Equipment Design License Participating in the development of non-nuclear internal components for Tsinghua University's third-generation nuclear power plant; the pressure vessel manufactured for this project has a maximum pressure rating of 17.5 MPa. Developing a Highly Efficient Multi-Stream Spiral Tube Heat Exchanger In the ethylene glycol project, the carbonylation reactor with a diameter of 4,600 mm is the largest heat exchanger produced by our company.
2014	Facilitating the technology transfer for ammonia-carbon separation and melamine off-gas treatment systems, while also developing and completing a new dimethyl carbonate production technology along with pilot-scale unit operation. In the 800,000-ton methanol project, the methanol inlet-outlet tower heat exchanger, with a length of 29,405.5 mm, is the largest heat exchanger produced by our company. The newly developed, highly efficient coiled-tube heat exchanger has been used for the first time in the Jiujiang Zhongke polypropylene plant.
2015	The high-efficiency coil-type reactor developed is used in coal-to-ethylene glycol and sulfur recovery units. Synthesis Reactor in the Coal-to-Methanol Production Project Completion of equipment supply for the JUMBO project PTA/PET plant destined for export to the U.S. (including heat exchangers and vessels) Completion of equipment for the crude oil atmospheric and vacuum distillation unit exported to Tajikistan (including heat exchangers, vessels, and towers)
2016	Completed the delivery of 7 units for the Iraq Graf Oilfield project to Malaysia.
2017	Completion of equipment for the Hub Coal-Fired Power Project (2 x 660 MW) in Pakistan’s Hub Export Project
2018	The highly efficient tubular heat exchanger design software V1.0 has been awarded the Computer Software Copyright Registration Certificate by the National Copyright Administration. Awarded the "2018 Top 100 Suppliers in China's Petrochemical Industry" by the China Petroleum and Chemical Industry Federation Independently developed, designed, and manufactured a 4000mm-diameter, 200,000-ton-per-year cyclohexanone dehydrogenation reactor featuring a short-circuit-resistant spiral baffle system.
2019	Delivering 1.8 million tons/year of reformed mixed feed heat exchange equipment to Sinopec (Guangdong) Refining & Chemicals. Coiled-tube heat exchanger receives Sinopec EPEC's A-level product quality rating
