In the high-stakes world of gas transportation, leakage is not an option. Our stainless steel gas pipes are engineered with molecular precision to ensure zero-permeability and high pressure resistance, meeting the stringent demands of modern energy grids.
As international energy markets shift toward LNG and hydrogen-blended natural gas, the demand for corrosion-resistant, high-grade stainless alloys (316L, 304, and Duplex) has surged by 15% annually among Fortune 500 energy firms.
From urban residential networks to deep-sea offshore platforms, our piping solutions provide the backbone for "Smart Gas" initiatives, integrating with IoT sensors to monitor flow and structural health in real-time.
Established in 2003, Shaanxi Kerlimar Engineers Co., Ltd. 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 global gas industry is currently undergoing its most significant transformation since the 1970s. As a leading manufacturer, Shaanxi Kerlimar is at the forefront of the Hydrogen Economy. Standard carbon steel pipes are susceptible to hydrogen embrittlement; however, our specialized stainless steel gas pipes are tested under high-pressure hydrogen environments to ensure long-term ductility and safety.
Optimization of Nitrogen-alloyed stainless steels to enhance yield strength while maintaining weldability.
Implementation of Cold-drawn Seamless (CDS) technology for uniform wall thickness and internal smoothness.
Blockchain-verified material traceability, ensuring every pipe's chemical composition is logged and immutable.
Reducing the carbon footprint of production through the vertical axis wind power technologies developed by Kerlimar.
Our chairman, Mr. Ming SUN, is a strong environmentalist and a fan of technological innovation. Since 2019, Kerlimar has launched clean energy technology research, focusing on new vertical axis wind power technology to solve the bottleneck of wind power. With over 40 patents, we aim to integrate our piping expertise with renewable energy infrastructure.
In December 2023, we were invited to participate in the Dubai COP28 Conference, reinforcing our commitment to controlling global average temperature rise below 1.5°C.
As a Famous Stainless Steel Gas Pipe Supplier & Manufacturer, we understand that industrial procurement is about more than just a product—it's about risk mitigation and supply chain resilience.
We provide localized technical support and documentation in accordance with regional regulations (e.g., PED in Europe, ASME in the Americas) to streamline your customs and installation processes.
Every batch of stainless steel gas pipe undergoes rigorous testing: Hydrostatic, Ultrasonic, and Eddy Current testing are standard procedures in our facility.
With 21 years of international trade experience, we have optimized our logistics to ensure timely delivery even in complex geopolitical climates.
| Material Grade | Chemical Optimization | Primary Application | Corrosion Resistance (PREN) |
|---|---|---|---|
| 304/304L | Low Carbon Content | Residential Gas Lines | 18.0 - 20.0 |
| 316/316L | Molybdenum Added | Coastal & Industrial Gas Grids | 23.0 - 28.5 |
| Duplex 2205 | Austenitic-Ferritic Structure | High Pressure Offshore Gas | 30.0 - 36.0 |

Our pipes undergo an enhanced annealing process that optimizes the grain structure for gas containment. Unlike general-purpose pipes, our gas pipes are specifically certified for high-pressure tightness and are tested for trace elements that could cause micro-cracking over decades of service.
We maintain a rigorous Quality Management System (QMS) certified to ISO 9001. Each shipment includes a Mill Test Certificate (MTC) to EN 10204 3.1, detailing the heat number, chemical composition, and physical properties of the specific batch.
Yes. We provide specific grades of stainless steel with optimized nickel and chromium content that minimize the risk of hydrogen-induced cracking, a critical requirement for the transition to green energy.
Standard sizes are often in stock. For custom manufacturing (specific wall thicknesses or lengths), our lead time typically ranges from 4 to 8 weeks, supported by our efficient factory logistics and proximity to major shipping ports.
Shaanxi Kerlimar Engineers Co., Ltd. continues to redefine the standards for gas infrastructure. With 21 years of expertise and a focus on the next generation of clean energy technology, we are more than a supplier—we are your technical partner for a sustainable future.
