Our History
Founded in the early 1990s, the company is located in the industrial heartland of the Yangtze River Delta, boasting complete industrial supporting facilities and superior port access. Over more than 30 years of dedicated development, it has evolved from a small processing workshop into a leading modern manufacturer of polyethylene pipe fittings in China. We specialize in the R&D, production and global import & export of PE pipe and fitting systems for gas supply and water drainage.
In the early stage of the industry, the domestic market for high-performance plastic gas pipe fittings was dominated by foreign brands. Leveraging independent material research and mold innovation, we took the lead in breaking through core production technologies and realizing the localized mass production of electrofusion fittings, ending the long-term monopoly of overseas products and driving the industrialization of plastic pipe network fittings across the country.
Throughout its development, the company has accomplished major milestones including full-range product expansion, construction of intelligent production bases, establishment of R&D platforms and standardized joint-stock reform, forming an integrated industry-university-research operation model.
Currently, we employ over 300 staff, among whom more than a quarter are professionals engaged in material R&D, mold design, fluid engineering and quality inspection. We maintain long-term technical cooperation with multiple domestic universities and material research institutes to tackle key problems such as pipe material modification and fitting structure optimization, and have undertaken numerous provincial, ministerial and national scientific research projects.
While deeply cultivating the domestic municipal supporting market, we ventured into international trade at an early stage. With products complying with international standards, we have steadily expanded our business to many countries worldwide.
After rounds of market upgrading and technological accumulation, we have moved beyond simple OEM production and grown into a full-industry-chain comprehensive service provider covering raw material formula development, independent mold manufacturing, large-scale production, product testing and certification, domestic and overseas project supporting as well as cross-border supply services.
We have built solid reputation and brand influence in the domestic and international gas pipe fitting sector. Ranked among the key tax-paying industrial enterprises locally for consecutive years, the company is also an appointed supporting supplier for major domestic gas groups.
Our Factory
Our enterprise owns two standardized and modern industrial production parks. Covering a total land area of nearly 300 mu with a total construction area exceeding 60,000 square meters, the parks adopt a zoning layout for production workshops, finished product warehouses, professional testing laboratories and new product trial-production workshops. All infrastructure and overall plant layout are constructed in accordance with EU environmental production specifications and national green factory standards of China, fully catering to diversified demands including mass production for bulk foreign trade orders, batch stock preparation and customized processing services.
The production parks consist of five dedicated functional zones: intelligent injection molding for electrofusion fittings, finishing processing for butt fusion fittings, assembly for steel-plastic composite fittings, precision processing for PE valves, and extrusion molding for PE pipes. Every workshop is fitted with independent constant temperature & dust removal systems, waste gas purification devices and reclaimed water recycling facilities. All environmental protection equipment has passed official EIA approval, with all discharge indicators meeting import environmental standards of European and American countries.
Our warehouse adopts a 3D intelligent shelf system, where goods are categorized by specification, type and export destination with sufficient permanent stock. This supports fast response to full-container overseas orders and shorter lead time. Multiple large container loading platforms are available on site. Located within a short drive from Shanghai Port and Ningbo Port, our plant enjoys convenient land transportation, offering remarkable sea freight advantages in delivery efficiency and overall logistics cost.
Supported by complete hardware facilities, our factory maintains stable and large-scale production capacity. The annual output reaches more than 15 million pieces of various PE pipe fittings, hundreds of thousands of sets of steel-plastic transition fittings, tens of thousands of professional PE valves and 50,000 tons of PE pipes. As one of the few domestic production bases capable of mass-producing large-diameter non-standard pipe fittings, we are competent to undertake OEM private labeling and ODM customized development businesses for overseas engineering projects.
The whole factory has implemented the 6S refined on-site management system and full visual control over the entire production process. Global purchasers can make appointments anytime for on-site factory audits or remote video tours covering the whole production chain.
