Its market presence is international, with export-oriented listings indicating sales to more than 20 or 30 countries depending on the source, alongside a sizable installed base of corrugated pipe extrusion lines.
History and development
Zhongyun’s business history is closely tied to the growth of China’s plastic pipe equipment sector. Public registration information identifies the company as established on 27 March 2000, with its legal representative listed as Zhang Qizhi in one business-profile source. The company’s own materials present it as a long-established specialist in corrugated-pipe equipment manufacturing, with a continuing focus on technology development and industrial upgrading.
Several development milestones are visible in the available sources:
- The company expanded from a pipe-equipment maker into a broader group structure, with official and semi-official materials describing Weifang Zhongyun Machinery Co., Ltd. and Weifang Zhongyun Science and Research Co., Ltd. as core business entities within Zhongyun Group.
- Factory listings and product pages indicate that Zhongyun built a substantial manufacturing base, citing multiple production bases, a provincial R&D center, and a large plant footprint.
- Company news materials report that in 2026 Zhongyun was included in Weifang’s green factory list and that its double-wall corrugated pipe production line was recognized as a basic-level intelligent factory, underscoring continued digitalization and process modernization.
Business operations and structure
Zhongyun is primarily an industrial equipment manufacturer rather than a plastics processor. Its public materials describe the company as focused on the manufacture of plastic corrugated pipe production equipment, and this segment is presented as one of the group’s core businesses alongside wind-power-related equipment in some company descriptions.
The company’s operating profile, as described across supplier and exhibition-style listings, includes:
- Manufacturing footprint: multiple production bases and a provincial R&D center.
- Workforce and scale: sources variously cite more than 300 employees or about 480 employees, reflecting differences in reporting date and platform.
- Export orientation: an international customer base in Europe, the Middle East, South Asia, and other markets.
- Integrated service model: design, manufacture, installation support, and after-sales service.
Because the available sources are primarily company and marketplace listings, detailed audited segment reporting is not publicly available from the material provided.
Products and technologies
Zhongyun’s best-documented products are corrugated pipe extrusion lines and related machinery used to manufacture pipes for drainage, municipal infrastructure, cable protection, and other industrial applications. The company’s product listings specifically mention equipment for:
- PE / PP / PVC double-wall corrugated pipe lines
- HDPE corrugated pipe machines
- PVC corrugated pipe production lines
- PP double-wall SN8 corrugated pipe extrusion lines
- Corrugated pipe cutters and pipe corrugators
Technical materials from the company and supplier platforms suggest that Zhongyun’s equipment emphasizes:
- High-output extrusion
- Stable forming of corrugated profiles
- Precision machining and manufacturing
- Automation and cost reduction in pipe production
- Longer service life and improved operating efficiency
The company also states that it has developed more than 10 advanced key technologies and 30 patents, and that its equipment has received awards in connection with multiple pipe-system categories, including PE/PP/PVC double-wall corrugated pipes, aluminum-plastic composite pipes, PP-R pipes, one-step PEX pipes, and UHMW-PE pipes. A company news item notes the installation of Makino horizontal machining centers, which indicates an emphasis on precision machining capability in core production.
Applications and end markets
Zhongyun’s machinery serves manufacturers that produce plastic pipes for a range of downstream infrastructure and industrial uses. Based on the product categories listed in company and distributor materials, the main end markets include:
- Drainage and sewerage systems
- Municipal infrastructure

The company’s corrugated-pipe lines, including large-diameter HDPE systems, suggest a strong presence in infrastructure-oriented applications where structural stiffness, ring strength, and production consistency are important.
Global presence and market position
Zhongyun positions itself as a specialized Chinese manufacturer with export sales in multiple regions. Source material indicates customers in more than 20 countries or more than 30 countries, including Russia, Japan, Iran, Iraq, Romania, Ukraine, and other markets. One product listing states that the company has delivered 700+ sets of corrugated pipe extrusion lines, while another indicates annual output capacity for corrugated pipe lines of 80 sets per year on a product page.
Industry-facing descriptions present Zhongyun as a significant domestic specialist in corrugated pipe machinery rather than a diversified plastics conglomerate. The company is also identified in a government or industry source as a specialized, refined, distinctive, and innovative “little giant” enterprise in Shandong, which is a Chinese designation for advanced small and medium-sized manufacturers with strong specialization and innovation capacity.
Sustainability and environmental initiatives
Zhongyun’s public materials increasingly frame manufacturing improvement through the language of green manufacturing and intelligent factories. Company news reports that the firm was selected for Weifang’s green factory list in 2026 and that its double-wall corrugated pipe production line was recognized as a basic-level intelligent factory.
The company’s own website also emphasizes producing corrugated pipes in an efficient, flexible, and sustainable manner through continuous technological innovation. In practical industrial terms, this likely reflects:
- lower unit energy consumption through improved line design,
- more stable extrusion and reduced waste,
- higher production efficiency,
- and digitized control to improve process consistency.
No detailed public environmental inventory, emissions dataset, or life-cycle assessment was identified in the provided sources.
