Established in 2003, Shaanxi Kerlimar Engineers Co., Ltd. has spent over 21 years defining the standards of the international pipe and fitting trade. Specializing in 6-inch Carbon Steel Pipes, alloy steel, and stainless steel variants, our reach extends across the global industrial landscape, from the oil fields of the Middle East to the infrastructure hubs of Europe.
As a National High-tech Enterprise certified in 2020, we don't just supply products; we engineer solutions. Under the leadership of Mr. Ming SUN, a visionary environmentalist, our company integrates traditional steel expertise with cutting-edge clean energy research, particularly in vertical axis wind power technology.
In the industrial nomenclature, "6 Carbon Steel Pipe" typically refers to two critical identifiers: NPS 6 (Nominal Pipe Size 6 inches) and ASTM A333 Grade 6. Both are pillars of modern industrial fluid transport.
A 6-inch pipe has an outside diameter (OD) of 6.625 inches (168.3 mm). Depending on the Schedule (SCH 40, 80, 160), the wall thickness varies to handle pressures from standard HVAC to extreme high-pressure steam lines.
Known for its low-temperature service capabilities, Grade 6 carbon steel is essential for LNG (Liquefied Natural Gas) transportation, maintaining impact toughness at temperatures as low as -45°C (-50°F).
Typical 6 carbon steel offers a minimum yield strength of 35,000 psi and tensile strength of 60,000 psi. Our pipes undergo ultrasonic and hydrostatic testing to ensure zero-leak integrity.
The global demand for 6-inch carbon steel pipes is surging due to the "Energy Transition" era. While the world moves toward renewables, the infrastructure required—hydrogen transport, CCUS (Carbon Capture, Utilization, and Storage), and geothermal loops—still relies heavily on the durability and cost-effectiveness of carbon steel.
Supply Chain Resilience: China's factory ecosystem, particularly in regions like Shaanxi and Hebei, provides a unique advantage. By leveraging the "Cluster Effect," Shaanxi Kerlimar ensures that raw material procurement, precision machining, and surface coating (like 3PE or FBE) happen within a tight geographic radius, reducing lead times by up to 30% compared to Western competitors.
At Kerlimar, we believe the future of steel is green. Our roadmap for 2024-2030 focuses on "Smart Piping Systems" and ESG compliance. We are not just a manufacturer; we are innovators invited to the China-Finland High Technology Match Conference and winners of the Excellence Award in the China Innovation and Entrepreneurship Competition.
Integration with Wind Power: Our research into vertical axis wind turbines (10KW-500KW units) utilizes the same structural integrity principles found in our high-grade seamless pipes. This cross-pollination of technology allows us to create more resilient pipe structures for offshore environments where wind and wave stress are constant.
In cold climates (e.g., Northern China, Eastern Europe, Canada), our Advanced Thermal Insulation Pipes are used for urban central heating, minimizing heat loss over kilometers of transit.
NPS 6 pipes serve as the primary conduits for intermediate product transfer. Our ASTM A106 Grade B seamless pipes offer the heat resistance required for refinery furnaces.
To combat saltwater corrosion, we supply Anti-Corrosion FBE Coated Pipes, ensuring a 50-year service life in aggressive maritime environments.
Supporting the infrastructure for our Vertical Axis Wind Turbines, carbon steel tubes provide the rigid framework for land-based and floating energy platforms.
