Hunan Wangkun Pipe Industry Co., Ltd., established in 2017 and
headquartered in Tianxin District, Changsha City, Hunan Province,
is a specialized enterprise in the thin-walled stainless steel pipe
sector. Focusing on the R&D, production, and sales of stainless
steel pipes and fittings for urban water supply and drainage,
medical applications, and gas transmission, the company has been
recognized as a “High-Tech Enterprise,” “Specialized, Refined,
Distinctive, and Innovative Small Giant Enterprise,” and “Changsha
Gazelle Enterprise.” In 2025, it was once again selected as a
“Hunan Provincial Green Factory,” solidifying its position as the
industry leader in thin-walled stainless steel piping within Hunan
Province. The company has also been recognized as one of “China's
Top Ten Stainless Steel Pipe Brands.” As the enterprise that filled
the gap in thin-walled stainless steel pipe production in Hunan
Province within the Central China region, the company has been
included in the province's pool of potential listed companies for
2024.
I. Core Competencies: Scale, Technology, and Quality Control
1. Scale and Equipment: With registered capital of RMB 120 million,
the company operates a modern production base exceeding 30,000
square meters. It houses nearly 100 advanced machines covering the
entire production process—from cutting and pipe forming to
polishing and inspection—alongside multiple state-of-the-art German
pipe/fitting production lines. A dedicated 500-square-meter R&D
facility ensures seamless technology transfer and production
efficiency.
2. Technology and Industry-Academia-Research Collaboration: The
technical team has actively participated in formulating 15
national, industry, regional, and group standards, holding
approximately 35 patents (including 9 invention patents), with
technical capabilities recognized by the industry. Independently
developed intelligent pickling and passivation production processes
enhance pipeline corrosion resistance and safety by forming dense
passivation films. Collaborations with Central South University and
Xiangtan University established a CNAS-accredited national-level
laboratory meeting state testing standards.
3. Quality Control & Management System: Leveraging CNAS lab
expertise, university research resources, and advanced
pickling-passivation technology, we built a fully digitalized
intelligent production line. Certifications include Measurement
Management System and ISO tri-system accreditation. Core stainless
steel water pipes exceed European and American sanitary inspection
standards, with a 70-year service life—far surpassing PVC pipes'
20-year lifespan. Resistant to corrosion and scaling, they inhibit
harmful microbial growth. All products undergo 100% inspection,
consistently meeting food-grade quality requirements.
