It mainly engages in the manufacturing, processing, and research and development of flange and petrochemical equipment accessories. It is the earliest in China. , one of the more large-scale professional manufacturers of flange production and forgings forgings for pressure vessels. The company covers an area of ​​78,000 square meters, of which the construction area is 48,000 square meters, and currently has more than 420 employees, including more than 170 engineering and technical personnel with college degree or above, and has nearly 300 million yuan in fixed assets.

The company mainly produces various materials (carbon steel, alloy steel [including high and low temperature steel] and stainless steel [inclusive of steel for high and low temperature] according to various international and domestic standards (ASME, ASNI, DIN, GB, JB/T, SH, HG, DG, etc.). Forged steel flanges including double-phase steel], and steel forgings for various boilers and pressure vessels, as well as mechanical and marine forgings. The products are widely used in petrochemicals, electric power (nuclear power, wind power, thermal power), light industry, machinery, In the fields of metallurgy and ships, the "Ceylon" brand enjoys a high reputation in China.

The company has excellent production equipment and now has dozens of forging equipment, including one forging machine of 7000 tons and 3600 tons, one forging machine of φ10 meters and φ6.5 meters CNC ring mill, one forging machine of φ1.5 meters and φ1.3 meters One ring grinder, one 1.5-ton air hammer, two one-ton air hammers, one 2-ton and one-ton electro-hydraulic hammers, nine forging inlet and discharge machines and operating machines of various types, and forging is heated by natural gas. Nine furnaces, fifteen industrial resistance furnaces for heat treatment, and more than eighty metal processing equipment. Among them, the largest CNC vertical truck with an annual output of 60,000 tons has been formed for medium and high pressure flanges and various boilers and pressure vessels. Manufacturing capability of steel forgings. The maximum pressure of the flange produced can reach 2500Lb, the maximum diameter can reach about ten meters, and the maximum weight of a single piece can reach 60 tons. The company has relatively complete physical and chemical facilities, including more than 40 sets of advanced instruments such as universal material testing machines, impact testing machines, spectrometers, ultrasonic flaw detectors, etc., and has a high-quality and multi-category quality assurance management team, forming a team from raw materials to finished products. A complete set of testing methods and quality management systems provide reliable guarantees for meeting product quality.

The company holds complete qualifications and has successively obtained ISO 9001: 2015 Quality Management System/ISO14001: 2015 Environmental Management System/ISO45001: 2018 Occupational Health and Safety Management System Certification Certificate, Special Equipment Production License, Civil Nuclear Safety Equipment Manufacturing License , PED, ABS, BV certificates, and intellectual property rights, integration of industrialization and industrialization and energy management system assessment certificates, etc.

Since 2011, the company has been recognized as a high-tech enterprise in Jiangsu Province. The company has Jiangsu Province High-performance Nitrogen Control Stainless Steel Product Engineering Technology Research Center and Jiangsu Province Enterprise Technology Center, and Southeast University, Jiangnan University, Southeast University Chengxian College, Sanjiang University, Hefei General Machinery Research Institute, Wuxi Jiangda University Science and Technology Park Many universities and research institutes have established close strategic cooperative relations and carried out effective industry-university-research cooperation. The company has participated in the formulation (revised) of 6 national or industry standards, developed more than 20 high-tech products in Jiangsu Province, and owned 70 national patents (including 11 invention patents). In recent years, the company has successively obtained Jiangsu Province Specialized and New Small Giant Enterprise (Manufacturing) certification, Provincial Specialized and New Small Giant - Standard Leadership, and Enterprise Cultivation Project Application. In 2022, it has successfully obtained national specialization. The recognition of the special new little giant and the green factory in Jiangsu Province has pointed out the direction for the innovative development of the enterprise.

The company always follows the quality policy of providing customers with high-quality products and thoughtful services, adheres to the corporate purpose of "unity, practicality, diligence and innovation", and abides by its reputation. Over the years, it has served as a large petrochemical company such as Sinopec, CNPC, CNOOC and other large petrochemical companies and the boilers and pressures to accompany them. Container manufacturers provide a large number of steel forgings for flanges and boilers and pressure vessels. In particular, the successful development of various high-pressure flanges has ended the situation of various high-pressure flanges in China relying on imports, saving foreign exchange for the country, saving construction time, and making positive contributions to the localization of flanges. Since 2003, the company has been engaged in domestic large-scale petrochemical new and expanded projects such as Nanjing Yangba, Shanghai Saike, Hainan oil refining, Lanzhou Daethylene, Guangpec hydrogenation, Dalian oil refining, Qingdao oil refining, Fujian oil refining, Huizhou oil refining, Dushanzi Projects such as oil refining ethylene, Guangxi Petrochemical Hydrogenation, Fushun Petrochemical Hydrogenation, Jinzhou Petrochemical Hydrogenation, Sichuan Petrochemical Oil Refining, Dalian Hengli PTA, Zhejiang Yisheng PTA and other projects provide a large number of flange products and have received unanimous praise from customers.

In 1999, the company's products successfully entered the nuclear power field and became a supplier of flanges and forgings for the Qinshan Phase II project. Since 2006, it has been expanded to the second phase of Lingao and the second phase of Qinshan, Pakistan C2, Hongyanhe, Ningde, Yangjiang, Fangjiashan, Fuqing, Taishan, Fangchenggang, Sanmen, Haiyang, Sanao, Xudabao, Zhangzhou, Nuclear power projects such as Lufeng provide a large number of nuclear-grade products and become the main suppliers of China National Nuclear Corporation, China General Nuclear Corporation and National Nuclear Basic Nuclear Flanges.
