Shaanxi Kerlimar Engineers Co., Ltd. was established in 2003 and has long been engaged in international trade business. We specialize in a variety of pipes – carbon steel, alloy steel, stainless steel materials – including seamless pipe, straight seam welded pipe, spiral welded pipe, and matching pipe fittings.
Our manufacturing standards conform to ASTM, ASME, EN, JIS and other international benchmarks, ensuring every product we deliver meets the most rigorous global specifications. We are committed to providing good quality, competitive pricing, timely delivery, and perfect service to clients worldwide.
With over two decades of industry expertise, Kerlimar has grown from a regional supplier into a globally recognized manufacturer and innovator – combining traditional industrial excellence with cutting-edge clean energy research and development.
The chairman of the company, Mr. Ming SUN, is a strong environmentalist and a passionate advocate for technological innovation. He deeply cares about climate change and environmental protection, continuously making efforts and taking concrete action toward a sustainable future.
Beginning in 2019, in response to the national call for innovation and entrepreneurship, Kerlimar launched its clean energy technology R&D program – focusing on next-generation vertical axis wind power technology. Our research targets the key bottlenecks in wind power, exploring pioneering directions including suspension systems, grid structure design, rail maglev systems, cable engineering, land floating, and offshore floating configurations.
These efforts reflect our conviction that industry leadership must go hand-in-hand with environmental responsibility – building a company that creates value not only for customers, but for the planet.
In December 2020, Kerlimar was awarded the prestigious National High-Tech Enterprise certification – a recognition of our sustained investment in research, innovation, and technical capability.
In June 2021, we were invited to participate in the China-Finland High Technology Match Conference, showcasing our vertical axis wind turbine technology to an international audience of experts and investors.
In August 2022, we competed in the 11th China Innovation and Entrepreneurship Competition, earning the prestigious Excellence Award for our breakthrough clean energy innovations.
In December 2023, we were honored to be invited to participate in the Dubai COP28 Conference – the world's premier platform for climate action and sustainable technology – representing China's innovative engineering sector on the global stage.
We have now completed 10KW–500KW series small unit pre-deployment experiments, and are actively participating in the national Thousands-of-Wind initiative. Our technology delivers outstanding efficiency, low cost, high reliability, high security, and easy control – poised to become an indispensable pillar of new productivity, supporting rural revitalization and the achievement of China's and the world's double-carbon goals.
We are committed to providing strong support for the global goal of limiting average temperature rise to below 1.5°C, creating a better and more sustainable future for all of human society.
