Modern polished stainless steel pipes aren't just about aesthetics. We utilize mechanical, chemical, and electrochemical polishing to achieve Ra values < 0.2µm, essential for preventing bacterial adhesion in high-purity applications.
The rise of the pharmaceutical and semiconductor industries in Southeast Asia and North America has tripled the demand for Bright Annealed (BA) and Electropolished (EP) piping systems.
As part of our commitment at COP28, we integrate recycled steel scrap and low-carbon manufacturing processes to reduce the carbon footprint of every ton of stainless steel produced.
Established in 2003, Shaanxi Kerlimar Engineers Co., Ltd. has spent over two decades mastering the international trade of piping solutions. Our expertise spans across carbon steel, alloy steel, and high-grade stainless steel. We specialize in seamless, ERW, and spiral welded pipes that meet stringent ASTM, ASME, EN, and JIS standards.
Our chairman, Mr. Ming SUN, is a visionary environmentalist who has steered the company toward technological innovation. Since 2019, we have expanded into clean energy, specifically vertical axis wind power technology, securing over 40 patents. This commitment to innovation is reflected in the precision and reliability of our stainless steel products.

When procuring polished stainless steel, understanding the finishing roadmap is critical for operational efficiency:
The global stainless steel pipe market is shifting from "bulk procurement" to "solution-based procurement." Enterprises are no longer just looking for a supplier; they are looking for a Lifecycle Partner. This includes:
Focus on "Dead-Leg" prevention and internal roughness control to ensure CIP (Clean-in-Place) efficiency.
Transitioning to high-molybdenum stainless steel grades to withstand offshore corrosive environments.
Demanding full traceability and material test reports (MTR) according to ASME BPE standards.
In December 2020, Shaanxi Kerlimar won the national High-tech Enterprise certification. Our technological prowess was further validated at the 11th China Innovation and Entrepreneurship Competition, where we received the Excellence Award. This spirit of excellence is infused into our stainless steel manufacturing lines, ensuring that every polished pipe we export is a product of high-tier engineering.
Mechanical polishing uses abrasive belts to grind the surface, which can leave microscopic scratches. Electropolishing is a chemical process that dissolves the outer layer, creating a smoother, more corrosion-resistant surface.
316/316L is superior for marine environments because it contains Molybdenum, which provides much higher resistance to chloride pitting and crevice corrosion compared to 304.
Each pipe is individually sleeved in plastic, followed by reinforced woven bags or seaworthy wooden cases. This prevents surface scratching and atmospheric contamination during sea freight.
We strictly follow ASTM A312, A213, A269, and EN 10217-7. All products come with EN 10204 3.1 certification for full material traceability.
Navigating the complexities of international trade requires more than just a good product. At Shaanxi Kerlimar, we provide comprehensive compliance documentation, including Mill Test Certificates (MTC), Certificate of Origin, and SGS/BV third-party inspections upon request. Our localization support ensures that whether you are in Europe, the Americas, or the Middle East, the pipes you receive meet both international benchmarks and local safety regulations.
As we look toward the future, the integration of Smart Manufacturing and AI-driven quality control on our production lines ensures that the "Famous Polished Stainless Steel Pipe" isn't just a title—it's a promise of uninterrupted performance and industrial longevity.
