Established in 2003, Shaanxi Kerlimar Engineers Co., Ltd. has spent over two decades at the forefront of the metallurgical and piping industry. As a premier China Seamless Black Steel Pipe Manufacturer, we integrate deep engineering expertise with a global distribution network. Our commitment to E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) is reflected in our adherence to ASTM, ASME, EN, and JIS standards.
In 2020, we achieved the National High-tech Enterprise certification, a testament to our focus on technological innovation. Our reach extends beyond simple manufacturing; we are active participants in global climate action, represented at the Dubai COP28 Conference, highlighting our shift toward sustainable production and clean energy solutions.
Chinese manufacturers utilize massive industrial clusters, particularly in Shaanxi and Hebei, to minimize raw material costs. This allows for competitive pricing without compromising the metallurgical integrity of the carbon steel.
From mandrel mills to cold-drawing processes, the precision of Seamless Black Steel Pipes from China has evolved to meet the highest tolerances required for high-pressure oil and gas transportation.
With a robust export infrastructure, companies like Kerlimar ensure "Timely delivery and perfect service," crucial for large-scale EPC projects in the Middle East, Europe, and the Americas.
Black steel pipe is named for the dark-colored iron oxide coating formed on its surface during the manufacturing process. Unlike galvanized pipe, it does not have a zinc coating, making it ideal for gas transport where zinc flaking could clog valves. The "Seamless" designation refers to the lack of any longitudinal weld seam, achieved through a piercing process of a solid billet.
To ensure global compatibility, our products meet rigorous specifications:
The global steel pipe industry is shifting toward Digitalization and ESG. Procurement managers are no longer just looking for the lowest price; they are seeking "Information Gain"—data on the carbon footprint of production, the traceability of ore, and the environmental impact of the lacquer coating used on black steel pipes.
At Shaanxi Kerlimar, we have pioneered the integration of Vertical Axis Wind Power Technology into our manufacturing ecosystems. This clean energy initiative, led by Mr. Ming SUN, solves the energy bottleneck of traditional heavy manufacturing, making our production process greener and more sustainable.
Established in 2003, engaging in international trade of pipes (Carbon Steel, Alloy, Stainless), including seamless, straight seam, and spiral welded varieties. Our standards encompass ASTM, ASME, EN, and JIS.
Since 2019, focused on clean energy and new vertical axis wind power research. With 40+ patents and participation in COP28, we are driving the "Whole Society Double Carbon Goals" through high-efficiency, low-cost engineering.
Structural support in airports, high-speed rail stations, and stadiums where high load-bearing capacity is required.
Natural gas distribution and oil refineries requiring pipes that can withstand extreme internal pressures.
Offshore platforms and shipbuilding where reliability in harsh environments is non-negotiable.
Large-scale commercial heating and cooling systems utilizing black steel for its thermal stability.
