Established in 2003, Shaanxi Kerlimar Engineers Co., Ltd. has spent over two decades cementing its reputation as a premier global supplier and manufacturer of high-performance piping systems. Our core specialization lies in the engineering and distribution of carbon steel, alloy steel, and stainless steel materials.
We provide a comprehensive range of products including Seamless Pipes, Straight Seam Welded Pipes (ERW), and Spiral Welded Pipes (SSAW), along with precision-matched pipe fittings. Every component we manufacture adheres strictly to international standards such as ASTM, ASME, EN, and JIS, ensuring that our clients receive products that excel in reliability, safety, and longevity.
Unlocking value through superior metallurgy and precision threading technology.
Threaded carbon steel pipes are the backbone of high-pressure fluid transportation. We utilize CNC precision machining to offer NPT (National Pipe Thread) and BSPT (British Standard Pipe Taper) threads, ensuring leak-proof connections for oil, gas, and steam applications.
To extend service life in harsh environments, our carbon steel pipes undergo rigorous surface treatments including hot-dip galvanizing, 3PE coating, and FBE epoxy lining. This "Information Gain" approach ensures our pipes outlast standard market offerings by 30%.
Using premium grades like ASTM A53, A106 Grade B, and API 5L, we guarantee superior tensile strength and ductility. Each batch undergoes non-destructive testing (NDT), hydrostatic testing, and ultrasonic inspection.
China accounts for over 50% of global steel production. This scale allows Shaanxi Kerlimar to offer competitive pricing without compromising on the metallurgical quality of our threaded pipes. Our integrated supply chain ensures rapid lead times for large-scale infrastructure projects.
Beyond traditional manufacturing, we are integrating AI-driven quality control and automated welding processes. As noted by our chairman, Mr. Ming SUN, we are committed to technological innovation that solves industrial bottlenecks while maintaining environmental stewardship.
Modern Chinese factories are no longer just "low cost." We are "high quality." With certifications in ISO 9001, API 5L, and CE, our products meet the stringent requirements of the North American, European, and Middle Eastern markets.
At Shaanxi Kerlimar, we believe industrial growth must coexist with environmental protection. Our chairman, Mr. Ming SUN, a dedicated environmentalist, has steered our research toward "New Vertical Axis Wind Power Technology."
With over 40 authorized patents, we are solving the bottlenecks of traditional wind power through rail maglev, grid structures, and land floating technologies. Our steel pipes are not just for oil; they are the structural framework for the next generation of renewable energy infrastructure, contributing to the "Double Carbon" global goal.

Thermal insulation pipes and high-pressure steam lines for traditional and nuclear power plants, ensuring thermal efficiency and safety.
In 2020, we earned the National High-tech Enterprise certification. Our journey of innovation has taken us to the China-Finland High Technology Match Conference and the 11th China Innovation and Entrepreneurship Competition (Excellence Award).
Notably, in 2023, we were invited to the Dubai COP28 Conference, showcasing our commitment to controlling global temperature rises. When you choose Shaanxi Kerlimar, you are partnering with a company recognized by global institutions for its integrity and forward-thinking engineering.
Carbon steel threaded pipes offer high tensile strength, ease of installation without specialized welding in some cases, and excellent pressure resistance. They are cost-effective and highly versatile for industrial plumbing and gas lines.
We use automated CNC threading machines and verify every thread against international ring and plug gauges to ensure compatibility and a perfect seal under pressure.
Yes, as a leading manufacturer, we provide OEM services including custom lengths, specific threading (NPT/BSPT), and advanced coatings like 3PE, Galvanizing, or FBE to meet project-specific requirements.
Seamless pipes are made from a solid billet and can withstand higher pressures, making them ideal for critical oil/gas apps. Welded pipes (ERW/SSAW) are more cost-efficient for structural and low-to-medium pressure applications.
We invest heavily in R&D for vertical axis wind power and utilize energy-efficient manufacturing processes to reduce the carbon footprint of our steel production, as showcased at COP28.
