Explore our engineering capabilities in heavy-duty gas recovery, mobile sterilization, and industrial-grade containment systems.
Pioneering Next-Generation Gas Purification and Pressure Vessel Systems
Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. was established in June 2021, with a registered capital of 78 million yuan. Located in the industrial core of Sanhe Economic Development Zone, Langfang City, we focus on the R&D and manufacturing of energy conservation and environmental protection systems. Our capabilities include various certified pressure vessels, medical waste treatment, coalbed methane/shale gas/natural gas purification, VOC treatment, industrial refrigeration, and BOG helium extraction.
Through close collaboration with academic heavyweights, we design filter housings and purification components that operate under extreme pressures and cryogenic environments, serving the petrochemical, environmental, and medical treatment industries globally.
Combining theoretical breakthroughs from top Chinese institutions with advanced manufacturing protocols.
Our team utilizes engineering talents from Tsinghua University and the Institute of Physics and Chemistry Technology, Chinese Academy of Sciences (CAS). We hold numerous independent intellectual property patents in skid-mounted liquefaction and containment.
We hold A2-level pressure vessel manufacturing licenses and pressure pipeline component manufacturing licenses. Certified to GB/T19001-2016 quality systems and Sinopec HSSE / China Petroleum Safety Management regulations.
Our systems reduce carbon emissions, prevent air pollution, and reclaim energy. We assist industries globally in meeting stringent environmental standards through safe VOC and gas desulfurization systems.

Dr. Sun is a national senior engineer who has led the National 863 Program and space cryogenic research. He holds awards like the First Prize of Science and Technology of China Coal Industry (2013) and Beijing Science and Technology Award (2016). He has overseen the implementation of over 50 skid-mounted liquefaction and filtration units.
Ph.D. candidate and senior engineer at the Institute of Physics and Chemistry Technology, CAS. He has managed several major science and technology initiatives and national aerospace projects. Author of 24 scientific papers (11 SCI/EI indexed) and holder of 5 national patents, he earned the Beijing Science and Technology Award First Prize in 2016.
Doctor of Engineering from CAS. Dr. Cheng specializes in skid-mounted natural gas liquefaction systems, phase-change heat transfer, and multi-component fluid flow dynamics. His process designs form the core of our non-standard pressure vessels and high-pressure filter housings.
Engineered for high-stress operating environments, from sub-zero liquefied gas fields to high-temperature bio-waste systems.
In modern process industries, filter housings are critical containment boundary components. As an A2-rated manufacturer, Hongke Qingneng designs and fabricates ASME-compliant vessel shells. Our systems are engineered to prevent gas bypassing, resist high pressures, and maintain high corrosion allowances in demanding fields:
Skid-mounted LNG processing requires filter housings capable of operating at -162°C. Thermal stress modeling is vital here; we utilize specialized SS304/SS316L structures to prevent hydrogen embrittlement and preserve sealing integrity.
H₂S and CO₂ removal systems require chemical-resistant housings. We supply heavy-duty, clad carbon steel and stainless vessels that resist sour environments, preventing sulfide stress cracking (SSC).
In animal carcass hydrolysis and medical waste sterilization, filter housings must handle high-pressure steam (up to 140°C) while trapping biological particulate matter and aerosols safely.
Technical Roadmap Highlight: We are integrating real-time pressure drop monitoring and high-efficiency particulate air (HEPA) coalescing filtration directly into our heavy-wall vessel flanges to reduce manual maintenance cycles.
Leveraging Hebei's manufacturing ecosystem to deliver high-precision vessels globally.
Our facility in the Sanhe Economic Development Zone provides strategic supply chain advantages. Our close proximity to domestic steel production hubs ensures immediate access to verified raw materials (ASTM plates, titanium, nickel alloys). This enables us to manufacture quickly while keeping costs low.
Our localized production lines integrate automatic welding systems, advanced non-destructive testing (NDT), radiographic examination (RT), ultrasonic testing (UT), and hydrostatic test bays. By utilizing these resources, we can complete projects 30-40% faster than western competitors without compromising on security standards.
