Engineered to international quality standards, providing high-efficiency recovery, treatment, and processing for industrial plants.
Established in June 2021 with a registered capital of 78 million Yuan, Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. has quickly emerged as a premier R&D-driven manufacturer in the Sanhe Economic Development Zone of Langfang City. Positioned within China's elite industrial manufacturing corridor, we focus on the engineering, design, and fabrication of advanced liquefaction systems, environmental protection equipment, and non-standard pressure vessels.
Our production line strictly implements global quality controls, supported by our A2 Level Pressure Vessel Manufacturing License, Pressure Pipeline Component Manufacturing License, GB/T19001-2016 (ISO 9001) quality system certification, and the rigorous Sinopec HSSE / China Petroleum Health, Safety, and Environment Management System certifications. As a recognized Langfang Municipal R&D Platform, we operate with a dual mission: offering high-efficiency machinery that minimizes carbon emissions, and delivering robust engineering that complies with regional and international codes.
Through deep academic integration with Tsinghua University and the Institute of Physics and Chemistry Technology of the Chinese Academy of Sciences (CAS), we provide global clients with proprietary cryogenic systems, boil-off gas (BOG) treatment solutions, VOC recovery modules, and advanced medical waste processing skids.
Our technologies are driven by leading experts in cryogenic physics, thermal thermodynamics, and chemical engineering from China's most prestigious research institutions.
Holding a Ph.D. from the Institute of Physics and Chemistry Technology, Chinese Academy of Sciences (CAS), Dr. Sun is a National Senior Engineer. He has spearheaded numerous high-level initiatives under the National 863 Program, the Natural Science Foundation, and major aerospace/military projects. His achievements include the Excellent Young Paper Award in Engineering Thermodynamics, the First Prize of Science and Technology of the China Coal Industry, and the Special Prize of Technological Invention from the Chinese Society of Refrigeration. Under his leadership, our factory holds over 20 independent R&D patents.
A PhD candidate and Senior Engineer at the CAS Institute of Physics and Chemistry Technology, Dr. Zou oversees Hebei Hongke's commercial affairs and operations. He has led projects under the "12th Five-Year Plan" for national technology specials, published 24 peer-reviewed academic papers (including 11 SCI/EI index publications), and holds 5 national invention patents. Dr. Zou was awarded the Special Award of the 7th China Refrigeration Society Technological Invention Award and the Silver Medal of the 19th China International Industry Expo.
Dr. Cheng earned his Doctor of Engineering from the CAS Institute of Physics and Chemistry Technology. He is a primary architect of our "Skid-mounted Natural Gas Liquefaction Unit Series." He specializes in phase change heat transfer characteristics and flow properties of multi-component mixed refrigerants. His foundational research in cryogenic flow ensures our wholesale liquefaction plants operate with industry-leading thermodynamic efficiency. He holds the First Prize of Science and Technology from the Beijing Municipal Government.
From custom process designs to global industrial deployment, we align academic precision with high-capacity factory output.
Our mixed refrigerant cycle (MRC) systems reduce operational energy consumption by up to 15% compared to traditional expander cycles, backed by thermodynamic research from CAS.
Our factory processes conform to ASME Section VIII, CE/PED, and GB standards. We undergo rigorous non-destructive testing (NDT), radiographic tests, and helium leak detection.
Every system is designed to support decarbonization objectives, capturing fugitive methane emissions, refining BOG, and isolating high-purity helium resources.
Leveraging China's manufacturing ecosystems to provide premium wholesale pricing and reliable project timelines.
Operating from our specialized facility in Langfang, Hebei, Hebei Hongke Qingneng integrates the structural, material, and logistical advantages of China's primary industrial base. This strategic location allows us to procure raw steel, high-performance cryogenic valves, and instrumentation from certified local suppliers, drastically reducing shipping costs and fabrication lead times.
Unlike small fabricators, our wholesale operations benefit from vertical integration. We manage everything under one roof: from structural plate rolling and high-frequency automated welding to cryogenic piping assembly and cold box vacuum insulation. This concentration of processes minimizes quality losses, limits subcontracting overheads, and guarantees that international buyers receive systems built to precise mechanical tolerances at factory-direct pricing.
Access to top-tier, low-temperature stainless steel (SS304/SS316) from verified domestic mills, ensuring robust cryogenic performance down to -196°C.
State-of-the-art automatic welding manipulators, plasma cutters, and dedicated clean rooms for cold box assembly to prevent particulate contamination.
100% radiographic inspection of critical weld joints, hydrostatic pressure testing, and high-vacuum helium mass spectrometer leak detection.
Skid-mounted, containerized structures designed for standard maritime shipping container footprints, lowering transport costs and simplifying onsite assembly.
Our systems deployed in real-world scenarios, solving complex cryogenic, municipal, and bio-safety challenges across diverse industries.
High-temperature hydrolysis systems deployed at biomedical centers for bio-safe, non-hazardous residue containment and volume reduction.
Fully integrated, truck-mounted medical waste sterilization units for flexible, rapid-response deployments in remote municipal sectors.
Compact skid-mounted LNG system recovering flare gas from remote oilfields, converting waste gas into high-value liquid fuel.
Industrial scale high-temperature steam autoclaves serving metropolitan hospitals with continuous feed, automated sterilization cycles.
Ensuring seamless integration of machinery in target markets through regulatory alignment and lifecycle engineering support.
Different regions demand strict adherence to local engineering codes. At Hebei Hongke, we bridge the gap between regional fabrication and international compliance. Our technical department is fully conversant in the application of the ASME Boiler and Pressure Vessel Code (Section VIII, Division 1 and 2), the European Pressure Equipment Directive (PED 2014/68/EU) for CE marking, and the Russian TR CU certifications.
By aligning design math, material selection, and structural safety margins with these codes, we ensure our clients experience zero compliance friction during local municipal inspections and plant startup phases.
Operating high-pressure liquefaction equipment requires professional calibration. We provide end-to-end site support, deploying senior technicians to oversee foundation alignment, cold box piping integration, and electrical testing.
Additionally, our systems are equipped with industrial IoT telemetry, allowing our engineers in China to remotely assist with diagnostic monitoring, parameter tuning, and troubleshooting. Through local regional partners, we also maintain a responsive stock of critical spare parts, including valve seats, pressure transmitters, and cryogenic seals.
