Established in 2003, Shaanxi Kerlimar Engineers Co., Ltd. has cemented its position as a global leader in the manufacturing and supply of high-grade stainless steel pipe rings, carbon steel tubes, and complex alloy pipeline components. For over 21 years, we have bridged the gap between advanced Chinese manufacturing and the stringent requirements of international infrastructure projects.
Our commitment to excellence is reflected in our adherence to global manufacturing standards, including ASTM, ASME, EN, and JIS. We don't just supply products; we provide engineered solutions that ensure the structural integrity and longevity of fluid transport systems worldwide.

Our pipe rings utilize high-grade SUS304 and SUS316L stainless steel. We implement precision cold-rolling and heat treatment processes to enhance tensile strength and eliminate stress points that lead to SCC (Stress Corrosion Cracking) in saline or acidic environments.
Utilizing CNC laser cutting and automated hydraulic forming, Kerlimar ensures dimensional tolerances within ±0.05mm. This precision is vital for high-pressure systems where pipe rings must allow for thermal expansion while maintaining structural support.
From electro-polishing to passivation, our surface treatment roadmap focuses on maximizing the chromium oxide protective layer. This technology extends the service life of pipe supports by up to 300% in offshore applications.
The global manufacturing landscape is shifting, and Shaanxi Kerlimar is at the forefront of Industry 4.0 integration. Our production facility utilizes IoT-enabled monitoring to track every stage of the manufacturing cycle for our stainless steel pipe rings.
Under the leadership of Mr. Ming SUN, a dedicated environmentalist, Kerlimar has expanded its technological horizon into clean energy. Our involvement in Vertical Axis Wind Power Technology and over 40 authorized patents demonstrates our commitment to the "Double Carbon" goals.
Our pipe rings and industrial components are designed to support the infrastructures of the future: hydrogen pipelines, offshore wind farms, and thermal control systems for green buildings. We believe that industrial growth must harmonize with environmental protection.
We navigate the complexities of international trade, ensuring all pipe rings meet CE, API, and ISO certifications. Our documentation process is streamlined for rapid customs clearance in EU, North American, and Southeast Asian markets.
By understanding local building codes and industrial standards (such as EN 10217 or ASTM A312), we tailor our manufacturing to fit specific regional project requirements, reducing on-site installation friction.
Our strategic location in Shaanxi allows us to leverage both the Belt and Road rail networks and major maritime ports, providing a dual-channel logistics advantage for both speed and cost-efficiency.
316L contains molybdenum, which significantly increases resistance to chlorides and marine environments compared to 304. It is essential for offshore oil & gas, chemical processing, and coastal infrastructure.
We utilize a multi-tier quality control system including ultrasonic testing (UT), radiographic testing (RT), and chemical composition analysis (PMI) to ensure every product meets the specified ASTM/ASME standards.
Yes. Our OEM capabilities allow us to design and manufacture custom pipe rings based on specific client blueprints, including variations in thickness, diameter, and locking mechanisms.
Standard orders typically ship within 15-30 days, depending on the volume and customization requirements. Our "China Factory 4.0" efficiency allows us to beat the industry average by 15%.
Absolutely. We are a certified High-tech Enterprise and emphasize environmental protection in our manufacturing, holding multiple patents in clean energy technology.
