Established in 2003, Shaanxi Kerlimar Engineers Co., Ltd. has evolved into a cornerstone of the international pipe manufacturing and trade sector. With over two decades of metallurgical expertise, we specialize in high-performance carbon steel, alloy steel, and stainless steel materials. Our portfolio encompasses seamless pipes, straight seam welded (ERW), and spiral welded (SSAW) pipes, alongside a comprehensive range of precision-engineered pipe fittings.
Our operations are anchored in global standards including ASTM, ASME, EN, and JIS, ensuring that every ton of steel delivered meets the rigorous safety and performance requirements of modern infrastructure. Led by Mr. Ming SUN, a visionary environmentalist, Kerlimar bridges the gap between traditional heavy industry and the future of clean energy.
Carbon steel remains the backbone of global industrialization. As we move into 2024-2025, the demand for "4 Carbon Steel" varieties (Low, Medium, High, and Ultra-High carbon) has shifted toward high-strength-low-alloy (HSLA) alternatives. Manufacturers are no longer just focused on raw tonnage; the industry's focus has pivoted toward information gain through data-driven manufacturing and ESG (Environmental, Social, and Governance) compliance.
Leading manufacturers are adopting Electric Arc Furnace (EAF) technologies to reduce the carbon footprint of steel production by up to 75%.
The integration of IoT sensors within carbon steel pipelines for real-time stress and corrosion monitoring is becoming a standard requirement.
Global procurement teams are prioritizing suppliers who offer end-to-end transparency, from raw material sourcing to final logistics.
From the deep-sea oil rigs of the Gulf of Mexico to the hydrogen transport networks in Europe, carbon steel pipes serve as the primary conduit for energy. Shaanxi Kerlimar provides macro-scale solutions that address these complex logistical and technical challenges.
We provide API 5L line pipes and API 5CT tubing/casing designed for high-pressure, sour-service environments (H2S resistance). Our solutions focus on minimizing leakage and maximizing the lifecycle of the wellbore.
High-precision rectangular and square section tubes are the preferred choice for modern architectural skeletons. They offer high torque resistance and a superior strength-to-weight ratio compared to open sections.
Our advanced thermal insulation pipes utilize multi-layer composite technology to maintain fluid temperature over long distances, essential for district heating and LNG transport.
Corrosion is the primary enemy of municipal water systems. We offer epoxy-coated and galvanized solutions that extend pipe life to over 50 years with minimal maintenance.
Shaanxi Kerlimar is not just a steel supplier; we are an innovation hub. Since 2019, we have expanded our R&D into Vertical Axis Wind Turbine (VAWT) technology. This cross-industry synergy allows us to apply pipeline engineering principles—such as suspension systems, rail maglev, and structural grid designs—to the renewable energy sector.
API 5L, API 5CT, ISO 9001:2015, and CE certification. We provide full MTC (Mill Test Certificate) traceable to the heat number.
Partnering with local logistics hubs in Hebei and Shaanxi to ensure FOB/CIF/DDP delivery terms are met with surgical precision.
Third-party inspections (SGS, BV, TUV) are welcomed. We perform ultrasonic, eddy current, and hydrostatic testing on 100% of critical-service orders.
