Direct manufacturer-sourced solutions offering high corrosion resistance, safety certifications, and premium flow-control capabilities.
Established in 2003, Shaanxi Kerlimar Engineers Co., Ltd. has spent over two decades developing high-integrity piping systems and structural materials for key energy industries globally. Our core product portfolio encompasses a comprehensive variety of pipes in carbon steel, alloy steel, and stainless steel, alongside top-grade seamless pipes, straight seam welded pipes, spiral welded pipes, and matching precision-crafted pipe fittings. We strictly manufacture in compliance with international engineering standards, including ASTM, ASME, EN, and JIS, to guarantee superior quality, competitive pricing, timely delivery, and a perfect lifecycle service.
Guided by our visionary Chairman, Mr. Ming SUN, we integrate advanced environmental protection and technological innovation into our corporate DNA. In response to global decarbonization mandates and early goals for double carbon society, we expanded our R&D scope in 2019 to include pioneering clean energy technologies, specifically focusing on vertical axis wind power systems to overcome mechanical bottlenecks in modern green power generation.
Understanding the rigorous parameters required by modern utilities and engineering firms when sourcing stainless steel gas piping systems.
Industrial, commercial, and utility sectors demand safety assurance systems for transport gas distribution. Sourcing gas pipes from China requires matching global regulations and standards. Mechanical stability, thermal durability, and exceptional resistance to localized chemical corrosion are non-negotiable qualities. Our stainless steel gas piping solutions address these issues by conforming to standard specifications:
Adherence to global standards like ASTM A312 (standard for seamless and welded austenitic stainless steel pipes), ASTM A269 (general service tubing), and EN 10217-7 (pressure purposes). This guarantees safe performance under high-pressure dynamics.
Utilization of premium austenitic alloys (TP304, TP304L, TP316, TP316L). The addition of Molybdenum in 316-grade variants provides outstanding resistance to chloride-induced pitting, making it suitable for marine environments and critical industrial chemical lines.
Unlike traditional copper or carbon steel pipes that are prone to scaling and embrittlement, stainless steel prevents chemical deterioration from wet gases and volatile sulfur compounds, lowering maintenance costs.
Our commitment to continuous technological development has earned us recognition at high-profile domestic and international forums. In December 2020, Shaanxi Kerlimar won the National High-Tech Enterprise Certification. In June 2021, we were invited to participate in the prestigious China-Finland High Technology Match Conference to foster cross-border energy solutions.
Additionally, we competed in the 11th China Innovation and Entrepreneurship Competition in August 2022, securing the Excellence Award. Highlighting our dedication to modern environmental frameworks, we were invited to participate in the Dubai COP28 Conference in December 2023, showcasing our alignment with international decarbonization efforts.
By refining our 10KW-500KW series of clean technology structures and pipeline integrations, we actively support global double carbon goals, providing solid support for keeping global temperatures below the critical 1.5°C threshold.
As global energy grids pivot from fossil fuels to clean hydrogen, materials science must adapt to the physical properties of light gas containment.
The main challenge with hydrogen transportation is its small atomic size, which allows gas to penetrate steel structures, causing hydrogen embrittlement. Standard carbon steel pipes often crack under high hydrogen concentration, but Shaanxi Kerlimar's austenitic stainless steel series is specifically processed to resist hydrogen penetration. The high nickel content in our alloys stabilizes the material structure, ensuring safety even in environments transport blends of up to 30% hydrogen.
Providing pipeline networks for municipal natural gas transport. High-grade stainless steel eliminates leaks, reduces pressure losses, and prevents safety hazards caused by corrosion under urban streets.
At cryogenic temperatures of -162°C, carbon steel becomes brittle and fractures easily. Our austenitic stainless steel pipes maintain high fracture toughness, making them ideal for handling liquefied natural gas.
Specially engineered pipes designed for petrochemical processing plants and ammonia synthesis setups where toxic and flammable gases must be directed safely through localized hot zones.
Ensuring global procurement standards are met with transparent testing, certified compliance, and reliable logistical processes.
Every stainless steel gas pipe manufactured by Shaanxi Kerlimar undergoes testing to verify its structural integrity and leak resistance under high-pressure conditions:
Our logistical systems prepare all pipes for international transport, using plastic caps for end protection, wooden crating, and rust preventative oil layers to prevent oxidation during sea transport.
Addressing key technical and operational questions from engineers and procurement teams.
Stainless steel provides superior corrosion resistance, especially against sour gas containing moisture and carbon dioxide or trace amounts of hydrogen sulfide. It prevents scaling, maintains clean interior surfaces for optimized gas flow dynamics, and has lower maintenance requirements, which offsets its higher initial cost over the pipeline's lifecycle.
TP304 is suitable for general land-based gas transport networks where environmental corrosion is moderate. TP316L contains 2-3% Molybdenum and has a lower carbon limit, providing protection against pitting in marine environments, chemical processing lines, and setups exposed to harsh coastal air.
Yes, we provide full OEM support, supplying outer diameters from 6mm up to 630mm and wall thicknesses from Schedule 5S up to Schedule XXS. We customize dimensions to meet specific operational pressure profiles and project design requirements.
Our involvement in advanced vertical axis wind turbines, wind power research, and low-carbon tech has refined our metallurgy expertise. Our systems are engineered to prevent micro-fissures and stress corrosion cracking under cyclical stress loads, aligning with global climate goals.
Ensuring structural integrity across transitions, bends, and distribution junctions.
