Premium solutions engineered to meet rigorous international standards for safety, thermal efficiency, and environmental compliance.
For modern industrial operations handling liquefied natural gas (LNG), coalbed methane (CBM), industrial gases, and ultra-low cryogenic refrigeration, insulation vacuum technology represents the thin margin between peak process efficiency and catastrophic thermal losses. Vacuum insulation uses a double-walled vessel structure where the interstitial space is evacuated to a high vacuum (typically below 1x10⁻⁴ mbar) and packed with Multi-Layer Insulation (MLI), preventing heat transfer via conduction, convection, and radiation.
At Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd., we combine state-of-the-art physics with advanced engineering to fabricate custom A2-level pressure vessels, skid-mounted gas treatment units, and refrigeration systems that operate seamlessly between -40℃ and -180℃. Our academic collaboration with Tsinghua University and the Institute of Physics and Chemistry Technology of the Chinese Academy of Sciences (CAS) ensures that our thermodynamic models translate perfectly to real-world performance.

We supply diverse industrial niches with custom, robust solutions engineered from high-grade stainless steel and vacuum-insulated jackets:
Our manufacturing and engineering base in Langfang City utilizes cutting-edge automated welding, precision helium leak detection, and advanced mechanical polishing to guarantee long-term vacuum longevity and minimize degradation over decades of service.
Selected engineering projects delivered globally with verifiable high performance and reliability.
Procuring wholesale vacuum-insulated piping, cold traps, and modular pressure vessel systems from China offers distinct supply chain advantages. Our Langfang facility leverage mature domestic steel supply chains (guaranteeing premier grades like 304, 304L, 316, and 316L stainless steel) and specialized fabrication clusters. By integrating local metallurgy with advanced manufacturing automation, Hebei Hongke Qingneng offers premium thermal isolation systems at optimized capital expenditure (CAPEX) points compared to Western counterparts, without compromising on materials testing or design tolerances.
B2B procurement of high-vacuum and high-pressure process equipment requires strict adherence to localized jurisdictional codes. Our engineering team designs and manufactures systems matching ASME Sec VIII Div 1, CE-PED, GB150, and national environmental safety standards. Furthermore, we provide end-to-end documentation including welding procedure specifications (WPS), non-destructive testing (NDT) records (radiographic, ultrasonic, and magnetic particle examinations), and comprehensive vacuum rise/degradation reports.
As the global market shifts toward clean fuels and carbon neutrality, vacuum-insulated containment has become vital for liquid hydrogen (LH₂) and liquefied natural gas (LNG) distribution. High-efficiency gas processing equipment must support quick installation. Skid-mounted, modular designs—where purification, compression, refrigeration, and vacuum insulated barriers are integrated into a single structural steel frame—are now industry standard. This modular approach reduces on-site labor costs, minimizes site commissioning times, and ensures factory-tested vacuum integrity remains intact during transport.
Answering critical engineering questions regarding vacuum integrity, thermal performance, and manufacturing standards.
High-precision manufacturing capabilities for advanced industrial processes.
Designed for biochemical, laboratory animal residue processing, and pharmaceutical applications. Our cold trap systems operate under deep vacuum conditions to eliminate dynamic moisture from exhaust gas systems. We offer custom heat exchanges and pressure vessel designs that allow high temperature steam hydrolysis without compromising system longevity.
Our solutions for raw gas and coalbed methane treatment remove heavy hydrocarbons, carbon dioxide, and water vapor. These systems utilize vacuum-insulated piping and double-wall vessels to prevent condensation and solid hydrates inside cooling loops, optimizing thermal efficiency and system uptime.
