Advanced non-standard pressure vessels and integrated gas processing solutions.
Established in June 2021 with a registered capital of 78 million yuan, Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. is a high-tech pioneer located in the industrial center of the Sanhe Economic Development Zone, Langfang City. Backed by elite partnerships with premier research institutions, we specialize in the design, engineering, and advanced manufacturing of environmental protection hardware, high-pressure equipment, and sophisticated cryogenic solutions.
Our multi-disciplinary operations encompass non-standard pressure vessels, medical waste autoclave systems, biological sterilization pipelines, and skid-mounted chemical processing configurations. Dedicated to carbon footprint reduction and industrial gas management, we deliver integrated recovery solutions for coalbed methane, shale gas, natural gas purification, and cryogenic helium extraction.
Modern heavy chemical industries, zero-emission gas processing, and bio-safety waste remediation systems require extreme structural integrity under high pressure and temperature differentials. Industrial oil pressure vessels function as the core reactors, phase separators, and storage units in complex gas liquefaction, desulphurisation, and cryogenic separations. In the wake of strict global environmental directives, simple containers are no longer sufficient. Today's global market demands high-performance, non-standard, and skid-mounted processing units capable of preventing toxic leakage while maintaining high thermodynamic efficiency.
The transition toward clean energy sources, such as liquefied natural gas (LNG), hydrogen vectors, and recycled coalbed methane (CBM), relies heavily on skid-mounted desulphurisation and heavy hydrocarbon removal systems. To address these demands, modern manufacturing must combine high-tensile metallurgical engineering with precision heat-exchange thermodynamics. This ensures safety, durability, and operational longevity in harsh environments.
Collaborating with Tsinghua University and the Institute of Physics and Chemistry Technology (Chinese Academy of Sciences), we leverage state-of-the-art academic breakthroughs to engineer advanced skid-mounted liquefaction and gas purification systems.
We hold the Chinese A2 level pressure vessel manufacturing license, pressure pipeline component manufacturing license, GB/T19001-2016 quality certification, and Sinopec HSSE / China Petroleum HSE safety credentials.
Our eco-focused processing equipment enables resource preservation and reduces carbon emissions, making key contributions to global air pollution mitigation and carbon neutrality initiatives.
Adapting pressure vessels and processing skids to local geographic, regulatory, and geological conditions is crucial for modern industrial applications. Below are the key scenarios where our customized equipment delivers reliable, long-term performance:
Our core R&D team consists of PhDs and senior engineers from top research institutions.
Operating in Langfang's Sanhe Economic Development Zone, Hebei, provides our factory with key structural advantages. We are positioned near major steel production centers, allowing us to source premium materials—such as high-grade carbon steel, specialized pressure vessel plates (Q345R, 16MnDR), and corrosion-resistant alloys (SS304, SS316L)—with short lead times.
By consolidating heavy cutting, automated welding, non-destructive testing (NDT), heat treatment, and hydrostatic validation within a single facility, we reduce logistics delays and maintain tight quality control. This integrated approach allows us to deliver high-quality, customized equipment on schedule, meeting the demands of large-scale international projects.
Our technical roadmap is designed to address the growing demand for higher processing efficiencies and reduced environmental impact. Key initiatives include:

Deploying high-pressure and cryogenic equipment globally requires strict adherence to international safety and engineering standards. We maintain comprehensive design controls and testing protocols to satisfy global regulatory frameworks:
In-depth insights into engineering specifications, customization capabilities, and compliance standards.
We select materials based on the operating temperature, design pressure, and chemical corrosiveness of the application. For standard pressure vessels, we utilize high-strength carbon steel plates like Q345R. For cryogenic installations (temperatures below -40°C down to -190°C), we specify low-temperature steels such as 16MnDR or 9% Ni steel. In corrosive environments containing H₂S or high-concentration CO₂, we manufacture vessels using SS304, SS316L, or dual-phase stainless steels, and offer explosion-bonded clad plates for cost-effective protection.
Our desulphurisation plants employ both dry-bed and wet absorption processes. The dry process utilizes high-capacity iron oxide or activated carbon catalysts to adsorb trace H₂S, which is suitable for polishing gas streams to pipeline specification. For high-volume acid gas processing, our wet processes use selective amines or advanced chemical solvents to strip H₂S and CO₂ from the natural gas, achieving removal efficiencies greater than 99.8% and preventing downstream pipeline corrosion.
Safety is critical for bio-hazardous processing. Our steam autoclaves feature automatic dual-door interlock systems to prevent accidental exposure and contain pressure. PLC control networks manage the sterilization cycle, maintaining temperatures at 134°C and pressures at 0.22 MPa. Off-gas and condensate lines are filtered and sterilized prior to release, preventing the escape of pathogens.
Skid-mounted systems consolidate piping, valves, heat exchangers, separation vessels, and electrical instrumentation onto a structural steel base frame. The skid is fully assembled, wired, and tested in our factory, reducing installation time and construction costs at the site. The modular design also allows for easier relocation as production needs shift.
Yes. As a licensed A2 manufacturer, we design and build vessels to match specific space, weight, and process requirements. We offer vertical and horizontal configurations, custom nozzle placements, multi-compartment designs, and specialized internal structures like demister pads, distribution trays, and internal heating coils.
We use professional mechanical modeling software and Finite Element Analysis (FEA) to simulate stresses and evaluate thermal expansion, wind loads, and seismic activities. This allows us to optimize wall thicknesses, reinforce high-stress nozzles, and design supports that prevent fatigue failure over the operational life of the vessel.
