Leading the market with high-performance alloys and custom fabrication.
The global stainless steel pipe coil market is undergoing a significant transformation. As industries move toward continuous processing to minimize leakage points and labor costs, the demand for extra-long, seamless coiled tubing has skyrocketed. In sectors like offshore oil and gas, these coils are critical for control lines and chemical injection systems where reliability is non-negotiable.
China has emerged as a global hub for high-precision ERW and SSAW manufacturing. By integrating advanced metallurgical processes with cost-effective logistics, Chinese manufacturers now provide the backbone for international infrastructure projects, meeting rigorous ASTM, ASME, and EN standards.
Moving beyond standard 304 and 316L, the industry is seeing a shift toward Duplex (S31803) and Super Duplex alloys. These materials offer superior pitting resistance and mechanical strength, essential for the emerging Hydrogen economy and aggressive chemical processing environments.
Pioneering the next generation of fluid handling technology.
Integration of real-time monitoring and AI quality control ensures zero-defect production in coiled tubing. Automated ultrasonic testing and laser diameter measurement are now standard in our premium production lines.
Aligned with Shaanxi Kerlimar’s environmental vision, we are implementing "Green Steel" initiatives. This includes utilizing renewable energy in the smelting process and optimizing the strength-to-weight ratio of pipes to reduce transport emissions.
Developing coils capable of withstanding 20,000+ PSI for deep-sea exploration and high-pressure chemical reactors, pushing the limits of seamless cold-drawn technology.
Established in 2003, Shaanxi Kerlimar has been a cornerstone of international trade for over 21 years. We specialize in carbon steel, alloy steel, and stainless steel materials, encompassing seamless pipes, straight seam welded pipes, and spiral welded pipes.

Our Chairman, Mr. Ming SUN, is a visionary environmentalist driving technological breakthroughs. Since 2019, we have expanded into clean energy, specifically vertical axis wind power technology, to solve traditional energy bottlenecks.
Recognized as a National High-Tech Enterprise, we have won excellence awards in the China Innovation and Entrepreneurship Competition and participated in global summits like COP28 in Dubai.
Tailored application scenarios for localized requirements.
Providing seamless stainless coils for solar thermal heat exchangers and geothermal energy systems. Our pipes ensure maximum heat transfer efficiency and thermal stability.
High-molybdenum stainless steel coils (316Ti / 904L) designed specifically to resist chloride-induced stress corrosion cracking in seawater environments.
Bright annealed (BA) and Electropolished (EP) coiled tubing that meets stringent sanitary requirements, preventing bacterial growth and contamination.
Stainless steel coils significantly reduce the number of orbital welds required in a system. Fewer welds mean fewer potential failure points (leaks), reduced inspection costs (radiography/X-ray), and a more compact design for high-efficiency heat transfer.
For high-precision applications, ASTM A249 and ASTM A269 are common. A249 covers welded tubes for boilers/superheaters, while A269 is for general service. Our factory ensures that ERW and SSAW pipes meet these rigorous dimensional and metallurgical tolerances.
We utilize multi-layer protective coatings and high-grade alloy selection. Our anti-corrosion solutions are tested via salt spray testing and electrochemical impedance spectroscopy to guarantee long-term performance in buried or submerged conditions.
Yes. By utilizing specialized alloy steels and thermal insulation technologies, we provide pipes designed for cryogenic service (-196°C) as well as high-temperature steam applications (up to 800°C).
The research into new vertical axis wind turbines allows us to understand structural stress and material fatigue at a deeper level. This cross-industry expertise helps us engineer better steel solutions for the renewable energy sector, integrating lightweight materials with high structural integrity.
