High-precision piping systems engineered for critical infrastructure and extreme environments.
Established in 2003, Shaanxi Kerlimar Engineers Co., Ltd. has spent over two decades at the forefront of the metallurgical supply chain. Our expertise spans the global trade of carbon steel, alloy steel, and high-grade stainless steel seamless pipes.
Unlike traditional brokers, we integrate advanced engineering knowledge with robust manufacturing standards such as ASTM, ASME, EN, and JIS. This ensures that every component—from straight seam welded pipes to intricate spiral welded systems—meets the rigorous demands of international fluid transmission and structural engineering.
The evolution of stainless seamless steel pipe technology from traditional cold-drawing to AI-optimized heat treatment.
Our roadmap emphasizes the development of Duplex and Super Duplex stainless steels (e.g., S32205, S32750). These materials offer double the strength of standard austenitic steels and superior resistance to chloride stress corrosion cracking, vital for offshore energy.
Utilizing vacuum annealing and controlled atmosphere quenching to eliminate intergranular precipitation. This ensures the long-term structural integrity of pipes used in high-temperature chemical processing and steam generation.
Implementation of Electrolytic Polishing (EP) and ultra-fine mechanical honing. For the pharmaceutical and semiconductor sectors, we achieve Ra < 0.25μm, preventing bacterial growth and ensuring ultra-high purity fluid transport.
In 2020, Shaanxi Kerlimar earned the National High-tech Enterprise certification. Our manufacturing philosophy is deeply rooted in the "Smart Factory" concept, combining vertical integration with decentralized quality control.
Where high-performance stainless steel meets world-class engineering challenges.
Corrosion-resistant seamless pipes (TP316L, TP317L) designed for acidic environments, crude oil distillation, and hydrocracking units where reliability is non-negotiable.
Supplying the next generation of vertical axis wind turbines and thermal control systems. Our stainless pipes facilitate high-efficiency heat exchange in clean energy modules.
High-chromium and molybdenum-rich alloys that withstand the aggressive "pitting" nature of saltwater, essential for ship-to-shore transfer and desalination plants.
Sanitary grade stainless steel pipes meeting FDA and EHEDG standards, featuring "seamless" interior joints to prevent product entrapment and contamination.
Precision small-diameter tubing for control systems, offering high pressure-bearing capacity and vibration resistance for aerospace and automotive testing.
Rectangular and square section tubes providing aesthetic brilliance combined with the structural strength of seamless engineering for modern sky-rise facades.
Bridging the gap between Chinese manufacturing power and local regulatory requirements.
We provide full certification for ASTM A312, A213, A269 and European EN 10216-5. All pipes undergo Hydrostatic Testing, Eddy Current Testing, and Ultrasonic Examination (UT).
To provide 100% reliability to global buyers, we welcome inspections from SGS, BV, Lloyd’s Register, and TUV. Transparency is the bedrock of our "Reliable Company" status.
Beyond shipping, we offer engineering consultation for pipeline design, welding procedure specifications (WPS), and material selection to optimize Total Cost of Ownership (TCO).
Mr. Ming SUN, Chairman of Shaanxi Kerlimar, believes that industrial growth must harmonize with environmental preservation. Since 2019, the company has pivoted toward clean energy technology research.
By focusing on vertical axis wind power—addressing bottlenecks like suspension, rail maglev, and floating structures—Kerlimar is contributing to the global "Double Carbon" goals. Our stainless steel pipes are a critical component in these new energy infrastructures, ensuring that we build a future that is both durable and green.
