Established in 2003, Shaanxi Kerlimar Engineers Co., Ltd. has stood at the forefront of the global industrial piping sector. With over 21 years of dedicated expertise, we serve as a premier manufacturer and international trade leader specializing in carbon steel, alloy steel, and stainless steel pipeline solutions.
Our commitment transcends simple manufacturing; we provide integrated engineering support that aligns with ASTM, ASME, EN, and JIS standards. As a recognized High-tech Enterprise, our portfolio includes seamless pipes, straight seam welded pipes, spiral welded pipes, and a comprehensive range of matching pipe fittings designed for high-pressure and high-temperature environments.
Leading the shift from traditional metallurgy to advanced performance alloys.
We are pioneering the use of micro-alloyed carbon steel to enhance yield strength without compromising weldability. Our technical roadmap focuses on grain refinement and controlled cooling processes (TMCP) to produce fittings that withstand extreme Arctic or deep-sea conditions.
Integration of 3LPE, FBE, and innovative graphene-based coatings. Our research ensures that the molecular bond between the carbon steel substrate and the protective layer is impervious to cathodic disbondment, extending pipeline life by up to 50 years.
Utilizing cold-drawn and hot-induction mandrels to ensure uniform wall thickness in elbows and tees. This precision minimizes flow turbulence and erosion-corrosion at the joints, critical for high-velocity liquid transport.
How we leverage smart manufacturing to ensure resilience and efficiency.
The Shaanxi Kerlimar manufacturing ecosystem is undergoing a digital transformation. By integrating IoT (Internet of Things) sensors across our production lines, we achieve real-time monitoring of heat treatment cycles and forging pressures. This "Smart Factory" approach ensures that every carbon steel fitting—from a simple flange to a complex lateral tee—meets the exact spectral analysis and mechanical property requirements before it leaves the floor.
Each fitting is laser-etched with a unique QR code linked to its Mill Test Certificate (MTC), ensuring 100% traceability from raw ingot to final installation.
In response to global "Double Carbon" goals, our factory has optimized induction heating systems, reducing carbon emissions per ton of steel processed by 18%.
Strategic stockpiling of raw materials and diversified logistics partnerships ensure that we meet "Just-in-Time" delivery demands even during global shipping fluctuations.
Tailored engineering for the world's most demanding sectors.
API 5L and API 6A compliant fittings for high-pressure sour gas environments. Our products are tested against HIC (Hydrogen Induced Cracking) and SSC (Sulfide Stress Cracking).
Leveraging our 40+ patents in vertical axis wind power tech, we design structural pipe components that serve as both transport conduits and structural supports for green energy infrastructure.
High-volume supply of carbon steel fittings for district heating, water desalination, and municipal wastewater treatment plants, focusing on cost-effective durability.
Navigating international regulatory frameworks is a core competency at Kerlimar. We don't just ship products; we provide localized compliance assurance. Whether it's PED (Pressure Equipment Directive) for Europe, CRN (Canadian Registration Number) for North America, or GOST standards for the CIS region, our documentation team ensures seamless customs clearance and site acceptance.
Our involvement in the Dubai COP28 Conference and the China-Finland High Technology Match Conference underscores our role as a global collaborator in sustainable engineering standards.
Led by Chairman Mr. Ming SUN, a visionary environmentalist, Shaanxi Kerlimar has diversified into clean energy technology. Since 2019, we have invested heavily in vertical axis wind power R&D, solving bottlenecks in suspension, grid structures, and rail maglev technologies. This synergy between "Steel and Wind" allows us to offer unique insights into the circular economy, where steel production supports the very renewable energy that will eventually power it.
While both are standard grades for moderate and high-temperature service, WPB is the most common carbon steel grade. WPC offers slightly higher tensile and yield strength, often required in specific structural applications. Shaanxi Kerlimar provides both, ensuring compliance with your project's specific stress analysis.
We welcome inspections from SGS, BV, ABS, and Lloyd’s. Our quality control system is designed to provide these agencies with full access to testing logs, chemical analysis reports, and hydrostatic test results to ensure total transparency.
Thanks to our Industry 4.0 integrated scheduling, standard fittings are available for immediate dispatch, while custom-forged components typically range from 4 to 8 weeks, depending on material availability and complexity of the heat treatment required.
Yes, we provide dedicated project managers for Large-scale EPC (Engineering, Procurement, and Construction) contracts, offering technical consultation from the design phase through to on-site commissioning.
