Product Description

Within the heart of a reciprocating piston compressor lies a sophisticated packing box, an intricate assembly of diverse sealing components nestled between the compressor cylinder and its middle body. The paramount mission of this ingenious setup is to ensure an impeccable seal, effectively thwarting any high-pressure gas from escaping along the piston rod's path. With precision-engineered packing components, meticulously assembled from multiple sets of sealing rings, they tenaciously grip the piston rod's friction surface under the formidable influence of gas pressure. This dynamic integrity gradually diminishes cylinder pressure, executing an unparalleled defense against any potential gas leakage.

Wenzhou Jianqing Industrial Company Strategically situated in the south Zhejiang Marine Economic Development Zone (Oujiang Estuary), our location is nationally recognized for developing a cutting-edge industrial cluster.
A heritage of excellence dating back to 1977, the history of our company is marked by three distinct phases of growth: Phase 1 (1976-1990), Phase 2 (1992-2002), and Phase 3 (2002-2023). It all began in 1976 when visionary founder Chen Jianqing, alongside his dedicated friends, embarked on a journey to craft high-quality valves. Despite facing numerous challenges, they triumphantly delivered their first batch of valves under limited processing conditions, thus securing the company's initial capital. By 1977, through relentless pursuit of excellence, they partnered with Longwan school office to establish the pioneering Wenzhou Tianlong Petrochemical Machinery Factory, focusing on the production of sealing rings. Although the early years were fraught with challenges due to a simplistic product structure and imperfect technical capabilities, the founders demonstrated resilience, addressing production and sales hurdles with ingenuity and determination.
In 1979, driven by a vision for expansion, the company diversified its product offerings beyond initial sealing components to include air valves, packing parts, pistons, piston rods, connecting rods, and bearing bushings. By 1984, the enterprise transitioned into the private sector, rebranded as Wenzhou Air Compressor Valve Factory, and proudly became Wenzhou's first manufacturer specializing in compressor components.
In 1990, our products gained market recognition, enabling us to join the ranks of designated production enterprises of the Petrochemical Industry Bureau (formerly the Ministry of Chemical Industry). We became esteemed members of the refining and chemical spare parts network of China National Gas Corporation, and part of the spare parts resource market of China Petrochemical.
In 1992, a strategic shareholding reform led to our rebranding as Wenzhou Jianqing Industrial Company, marking a pivotal shift in our organizational trajectory.
Entering the new millennium, we embraced continuous innovation, transitioning from import imitation to independent design and research and development. Through incremental advances, we have solidified our standing in the industry.
Product category introduction: Jianqing Industrial's core offerings include three major wear-resistant components: air valves, piston ring support rings, and packing rings, as well as gas regulators (actuators) and check valves. Our design philosophy has undergone significant evolution, particularly evident in our air valves, which have advanced from initial metal mesh designs to a diverse array of structural types such as ring inclined, mushroom, and infinity valves.
Our extensive client base spans across various Chinese provinces, including esteemed entities like Yanshan Petrochemical, Cangzhou Petrochemical, Shijiazhuang Refining and Chemical, State Pipeline Network, Xinhai Shihua, Dagang Oil Field, Haiwei Petrochemical, Shanxi Luan, PetroChina Jingtang LNG, and others. We are also proud suppliers to Daqing Petrochemical, Daqing Refining and Chemical, Harbin Petrochemical, Fushun Petrochemical, Dalian Petrochemical, Western Pacific Petrochemical, Jilin Petrochemical, Baolai Group, Jilin Oilfield, among others. In East China, our clientele includes Zhenhai Petrochemical, Zhejiang Petrochemical, CNOOC Daxie Petrochemical, Qilu Petrochemical, Qingdao Petrochemical, Sinochem Quanzhou Petrochemical, Jinling Petrochemical, Yangtze Petrochemical, Wanhua Chemical Group, and more. Recently, we have expanded into international markets, exporting to Brunei, Russia, the Middle East, and beyond through major engine manufacturers. We anticipate further expansion into these promising markets.
