Experience & Expertise: For over two decades, the Chinese steel industry has transitioned from high-volume production to high-precision engineering. As a leading China Steel Carbon Pipe Supplier, the focus is now on Semantic Search relevance—meaning we don't just provide "pipes," we provide engineered solutions for high-pressure fluid dynamics, thermal stability, and structural integrity. Shaanxi Kerlimar Engineers Co., Ltd. (est. 2003) represents this evolution, blending 21 years of trade expertise with cutting-edge manufacturing standards including ASTM, ASME, EN, and JIS.
Optimizing carbon steel pipelines for the Oil & Gas, Desalination, and Urban Infrastructure sectors with integrated valve and fitting systems.
Leveraging automated LSAW/ERW lines and IoT-driven quality control to ensure 100% traceability and zero-defect output.
Full adherence to ISO 9001, API 5L, and CE certifications, ensuring seamless entry into EU, North American, and GCC markets.
Shaanxi Kerlimar Engineers Co., Ltd. was established in 2003, has long been engaged in international trade business, mainly a variety of pipes, carbon steel, alloy steel, stainless steel material, seamless pipe, straight seam welded pipe, spiral welded pipe and matching pipe fittings. Manufacturing standards for ASTM, ASME, EN, JIS and so on, in line with international standards. We are providing good quality, price competition, timely delivery, perfect service!
The roadmap for carbon steel pipe focuses on Grade X80 and X100 development. By optimizing the micro-alloying of Niobium and Vanadium, we increase tensile strength while reducing wall thickness, leading to significant cost savings in logistics and installation for global enterprises.
Beyond traditional 3LPE/3LPP, the future lies in Nano-Composite anti-corrosion layers. These coatings offer superior resistance to cathodic disbondment, extending pipeline life in subsea and highly acidic soil environments to over 50 years.
As the world pivots to the Green Hydrogen Economy, our carbon steel pipes are undergoing "Hydrogen Embrittlement" testing. We are developing specialized internal linings and low-carbon weld chemistries to support 100% pure hydrogen transport.
The chairman of the company: Mr. Ming SUN, is a strong environmentalist and a fan of technological innovation. He cares about climate change and environmental protection, and makes continuous efforts and takes action for it.
Began in 2019, in response to national innovation, we launched clean energy technology R&D, focusing on new vertical axis wind power technology. To solve wind power bottlenecks, we focus on research of rail maglev, land floating, and grid structures. More than 40 patents have been authorized by the State Intellectual Property Office, spreading our new technology to global markets.
The "Information Gain" for modern procurement teams lies in understanding Supply Chain Transparency. In the Steel Carbon Pipe sector, China’s Factory 4.0 integration means:
In December 2020, we won the national High-tech Enterprise certification. In June 2021, we were invited to participate in the China-Finland High Technology Match Conference. By August 2022, we participated in the 11th China Innovation and Entrepreneurship Competition, winning the Excellence award.
Currently, we have completed 10KW-500KW series experiments. With efficiency, low cost, and high security, this series will contribute to the "Double Carbon" goals andrural revitalization, supporting the goal of controlling global temperature rise below 1.5°C.
We provide comprehensive MTC (Material Test Certificates) to EN 10204 3.1 or 3.2. This ensures that every pipe supplied meets the specific yield strength and impact toughness required by global engineering firms.
Understanding regional regulations (e.g., Saudi Aramco 9-SAMSS-091 or Shell DEP) is our forte. We offer localized documentation and bilingual support to bridge the communication gap between the factory and site engineers.
For large-scale infrastructure, we offer Just-In-Time (JIT) delivery. By staging inventory in bonded warehouses, we mitigate the risks of site delays and storage costs for our partners.
Seamless pipes are manufactured via extrusion and have no weld seam, making them ideal for high-pressure applications. Welded pipes (ERW, LSAW) are formed from steel plates and are more cost-effective for large diameters and lower-pressure applications. As a leading supplier, we provide both based on your project's safety factor requirements.
Quality is maintained through a 21-year refined process involving raw material chemical analysis, hydrostatic testing, flattening tests, and ultrasonic inspection. Our ISO 9001 certification and "High-tech Enterprise" status validate our commitment to rigorous QC standards.
Yes. For low-temperature service, we supply ASTM A333 Grade 6 pipes. For corrosive environments, we offer external 3LPE coatings and internal epoxy linings, significantly increasing the lifespan of the pipeline.
Lead times vary depending on specification, but typical production cycles range from 30 to 45 days. Our strategic location in Shaanxi with access to major transport hubs ensures streamlined logistics to any global port.
