Patent (CN 222056998U) for "a jacketed reactor with high mixing degree of materials"

Yangzhou Tongyang Chemical Equipment CO. LTD (hereinafter referred to as "TongYang") has received positive feedback from customers in the market, mainly in terms of technological innovation, service support and market expansion. 

Below is the information analysed from the comprehensive search results:

1. Technological innovations and patent achievements

Patent for High Mixing Kettle: In November 2024, Tong Yang Chemical obtained the patent (CN 222056998U) for "a jacketed reactor with high mixing degree of materials" authorised by the State Intellectual Property Office (SIPO). Through the unique design of stirring blades (triangular structure + secondary shear), this equipment significantly improves the dispersion and mixing effect of high viscosity materials, reduces the resistance, and solves the pain point of uneven mixing in chemical production. This innovation directly responds to the customer's demand for efficient production equipment, and the technological advantage has become the core basis for positive feedback.

2. Market performance and client recognition

Long-term cooperation and performance growth: According to the record of ICBC Yangzhou branch visit, Sun Guilong, chairman of Tongyang Chemical, mentioned that the company has developed from "annual sales of a few million" to "nearly 300 million" scale, and ICBC's continuous financial support (e.g., relocation of the bonded area in 2022, reloading workshop construction in 2023) has helped to upgrade production capacity. 

Customers' affirmation also reflects their trust of us.

Major projects in production: In February 2025, its "10,000-tonne catalytic cracking reaction distillation equipment production project" completed construction, and the project payment guarantee fund entered the stage of refund announcement, indicating that the large-scale project has been successfully landed, and the client (Yangzhou City Baitai Construction Co., Ltd.) did not raise any objections, which side by side confirms the satisfaction of the equipment delivery.

Market Coverage: The products are sold to more than 20 provinces, cities and autonomous regions across the country and exported overseas, and the wide customer base corroborates the market acceptance of the equipment.

3. Services and financial support reinforce client trust

Deepening cooperation between banks and enterprises: ICBC Yangzhou Branch listed Tong Yang Chemical as a key target of the "Thousands of Enterprises and Ten Thousand Households Visit", and took the initiative to provide customised financing solutions to solve the enterprise's financial problems in expansion. This close financial service relationship has indirectly improved Tong Yang's responsiveness to customer needs (e.g., shortening delivery cycle, optimising after-sales service).

Customer feedback mechanism: the company adheres to the principle of "customer satisfaction, integrity first", and through its subsidiary Longshengda to provide technical service system, covering the design, manufacturing, installation of the whole process, reducing the threshold of customer use.

4. Qualification and production capacity to guarantee the quality of equipment

Complete industry certifications: Holding A2 class pressure vessel manufacturing licence, D1/D2 pressure vessel design licence, PetroChina engineering qualification, etc., in line with high standard safety norms.

Advantage of technical cooperation: cooperating with universities in the research and development of tower separation, crystallisation and evaporation technology, solving the pain points of customers in expanding production in the field of environmental protection and emission reduction.

5. Summary

The positive feedback on TongYang stems from its patented technology to solve production pain points, its ability to deliver major projects, its perfect after-sales service system, and the reliability of its qualification guarantee. Customer recognition is reflected both in the ten-year growth of sales (million → nearly 300 million) and in the smooth acceptance of large-scale projects and the continuous expansion of domestic and international markets. In the future, school-enterprise cooperation and financial support may further strengthen its technology iteration and cash flow.
