Established in June 2021 with a registered capital of 78 million Yuan, Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. has grown rapidly to become a prominent leader in the industrial pressure vessel and environmental protection manufacturing sectors. Located within the Sanhe Economic Development Zone, Langfang City, our state-of-the-art facilities produce heavy-duty processing machinery, pressure piping systems, and customized, non-standard compression vessels.
Through our dedicated integration of engineering design, structural welding, thermodynamic research, and high-precision testing, we service energy markets, chemical tail gas purification, VOC mitigation, BOG helium extraction, and biosecurity sterilization. We remain committed to helping global industries maximize process efficiency while minimizing carbon footprints.
Our engineering superiority lies in our R&D partnership with China's leading research institutes and world-class cryogenic experts.
Collaborative partnerships with Tsinghua University and the Institute of Physics and Chemistry Technology, Chinese Academy of Sciences (CAS). We have secured multiple patents and independent intellectual property protections for mixed refrigerant cycles, cryogenic separations, and thermal processes.
Licensed under A2 Class Pressure Vessel Manufacturing and pressure pipeline component guidelines. We are fully certified under GB/T19001-2016 (ISO 9001:2015), Sinopec HSSE, and CNPC Health, Safety, and Environment Management Systems.
We are a certified national high-tech enterprise. Our customized environmental skids, VOC thermal treatment, desulfurization columns, and recovery plants actively contribute to global carbon emissions reduction and clean air initiatives.
Compression vessels are critical components in petrochemical refining, natural gas liquefaction, biochemical sterilization, and environmental scrubbers. High-pressure compression vessels must be engineered to endure extreme environments, ranging from cryogenic liquids (-196°C) to superheated industrial steam. Structural integrity is preserved using Finite Element Analysis (FEA) to calculate localized stress concentrations, ensuring safety under cyclical loading.
Our A2 class manufacturing capabilities permit the construction of thick-walled high-pressure cylinders. These vessels utilize advanced metallurgy, including low-temperature carbon steels (e.g., SA-516 Gr. 70) and austenitic stainless steels (e.g., SS304/316L). Standardized non-destructive testing (NDT), such as Radiographic (RT), Ultrasonic (UT), and Magnetic Particle testing (MT), is carried out to guarantee flawless weld seams before hydro-testing.
Choosing a wholesale manufacturer from China provides significant advantages in raw material access, specialized engineering, and manufacturing speed. By leveraging Langfang's industrial corridor, we gain direct access to premium domestic steel producers, cutting down transit times and lowering raw material costs.
Operating a high-pressure compression vessel requires compliance with localized regulatory frameworks. To guarantee global safety and smooth import processes, Hebei Hongke Qingneng aligns its engineering and fabrication practices with international standards:
Our localized support division provides complete documentation packages, including material test reports (MTRs), hydro-test charts, NDT logs, and welding procedure specifications (WPS). We work alongside third-party inspectors like SGS, TÜV, and Bureau Veritas to simplify final acceptance testing.
Our compression vessels and skid assemblies support a wide range of industrial applications:
The global compression vessel industry is transitioning toward smart, integrated systems. Instead of field-installing separate tanks and piping, modern projects use pre-piped, pre-wired skid units equipped with smart instrumentation. The demand for green hydrogen, bio-LNG, and carbon capture technology (CCUS) requires vessels capable of holding gas at higher pressures with zero leak rates. Additionally, helium extraction from BOG (Boil-Off Gas) has emerged as a high-value technology to recover helium resources during LNG operations.

We hold the Chinese A2 Level Pressure Vessel Manufacturing License, Pressure Pipeline Component Manufacturing License, ISO 9001 (GB/T19001-2016) certification, and environmental management credentials. We also design and fabricate vessels compliant with ASME Section VIII and PED 97/23/EC standards for overseas markets.
Yes. Our CAS and Tsinghua-trained engineering team specializes in custom designs. We perform stress calculations and finite element analyses to build customized shell-and-tube heat exchangers, high-temperature sterilizers, cryogenic vessels, and separation skids to your exact dimensions and process specifications.
We perform 100% Non-Destructive Testing (NDT) including Radiographic Testing (RT), Ultrasonic Testing (UT), Magnetic Particle Testing (MT), and Dye Penetrant testing. This is followed by hydrostatic and pneumatic testing to verify mechanical strength and structural integrity before shipment.
Skid-mounted systems are fully integrated modules where the vessels, piping, valves, instrumentation, and electrical controls are pre-installed on a heavy-duty structural steel frame at our factory. This transforms installation into a quick plug-and-play connection, minimizing field welding and electrical work.
We design vessels for temperatures as low as -196°C for cryogenic liquid storage (LNG, liquid nitrogen, liquid oxygen) and high-vacuum configurations. Our high-pressure vessels can support designs exceeding 10 MPa depending on wall thickness, diameter, and metallurgical limits.
