Established in 2003, Shaanxi Kerlimar Engineers Co., Ltd. (Sunwin Brand) has spent over two decades cementing its reputation as a global leader in high-performance piping systems. We specialize in an extensive range of materials including carbon steel, alloy steel, and premium stainless steel.
Our commitment to excellence is reflected in our adherence to international manufacturing standards such as ASTM, ASME, EN, and JIS. By integrating supply chain agility with rigorous quality control, we ensure our global partners receive competitive pricing, timely delivery, and unparalleled technical support.
Our R&D is currently focused on developing specialized stainless steel pipes resistant to hydrogen embrittlement. As the world shifts toward green hydrogen, Sunwin is positioning its products to be the backbone of the next energy revolution.
Lead by Mr. Ming SUN, a visionary environmentalist, we are pioneering vertical axis wind turbine technologies. By integrating grid structures, rail maglev, and floating land designs, we solve traditional wind power bottlenecks.
The future of piping is "intelligent." We are exploring the integration of IoT sensors within our pipe fittings to provide real-time data on flow rates, pressure fluctuations, and corrosion levels for industrial 4.0 applications.
Sunwin leverages the "China Factory 4.0" model, combining automated manufacturing with a highly integrated supply chain to deliver high-precision stainless steel products with zero-defect goals.
Our centralized procurement and logistics hub in Shaanxi ensures that even complex, large-scale orders are processed with peak efficiency, reducing lead times by up to 30% compared to traditional manufacturers.
From the raw melt to the final polish, every Sunwin stainless steel pipe undergoes ultrasonic testing, hydrostatic pressure tests, and spectral analysis to ensure 100% compliance with ASTM/ASME standards.
As participants in the Dubai COP28 Conference, we implement closed-loop water systems and energy-efficient smelting processes, minimizing the carbon footprint of every ton of steel produced.
Sunwin Stainless Steel is not just a product; it’s a critical component for global infrastructure. We provide tailored solutions across diverse sectors:
We maintain ISO 9001:2015, CE, and PED certifications. Our products are exported to Europe, Southeast Asia, and the Middle East, meeting all local regulatory requirements for pressure equipment.
Our engineering team provides localized support, including on-site consulting and material selection guidance, ensuring that the steel grade matches the specific environmental stressors of your project.
With over 40 domestic and numerous international PCT patents, we provide our partners with innovative, proprietary technology that gives them a competitive edge in their local markets.
Whether you require high-precision stainless steel pipes for a chemical plant or innovative support for wind energy infrastructure, Shaanxi Kerlimar Engineers Co., Ltd. has the technical depth and manufacturing capacity to deliver.
