Explore our leading catalog of industrial purification, gas recovery, and heavy-duty pressure equipment engineered for complex processing environments.
Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. was established in June 2021 with a registered capital of 78 million yuan. Situated in the core industrial hub of Sanhe Economic Development Zone, Langfang City, we focus on the R&D and manufacturing of energy conservation and environmental protection systems.
We stand at the forefront of process engineering, specializing in custom A2-level pressure vessel manufacturing, biomedical waste sterilization systems, chemical tail gas (VOC) treatment plants, and advanced skid-mounted liquefaction facilities. Our engineering philosophy merges scientific theory with robust factory execution to serve demanding clean-energy applications globally.
Our technologies are driven by core scientific talents from Tsinghua University and the Institute of Physics and Chemistry Technology, Chinese Academy of Sciences (CAS).
Ph.D. from the Institute of Physics and Chemistry Technology, CAS. Recipient of the National 863 Program grants and major Natural Science Foundation projects. Winner of Beijing Science & Technology Award (1st Prize, 2016) and Chinese Society of Refrigeration Technological Invention Award (Special Prize, 2015). Presided over 20+ independent R&D patents.
Senior Engineer at the Institute of Physics and Chemistry Technology, CAS. Published 24 academic papers (11 SCI/EI indexed) and holds 5 patents. Spearheaded high-end manufacturing optimization and petrochemical-grade gas processing system deployment across China's major gas fields.
Ph.D. of Engineering from CAS. Leading researcher in multi-component phase change thermodynamics. Successfully implemented 50+ sets of small-scale skid-mounted LNG liquefaction systems. Designed advanced non-standard thermal exchangers and high-pressure steam distribution headers.
We bridge the gap between academic thermal engineering breakthroughs and rugged industrial manufacturing. Our production compliance profiles guarantee flawless field operation.
Our deep collaboration with national laboratories allows us to optimize phase-change characteristics under extreme heat exchange conditions. We hold proprietary patents on industrial refrigeration machinery working at temperatures from -40°C down to -180°C.
Our plant possesses the national A2-level pressure vessel manufacturing license, alongside specialized pressure pipeline component manufacturing permits. We are fully certified under GB/T19001-2016, Sinopec HSSE, and CNPC Quality, Safety and Environmental Management Systems.
Combining structural safety margins with lean manufacturing workflows to deliver high-integrity welded pressure vessels.
As an industry-leading manufacturer, our facility employs automated submerged arc welding (SAW), gas tungsten arc welding (GTAW), and orbital welding centers to maintain continuous weld integrity. By standardizing high-yield steel plate sourcing (Q345R, 16MnDR, and stainless grades 304L/316L), we minimize macro-porosity and heat-affected zone (HAZ) cracking.
Through our local integration in the Sanhe Economic Development Zone, Langfang, we run a completely vertical supply chain. From engineering plate rolling and heavy dished head pressing to post-weld heat treatment (PWHT) and non-destructive testing (NDT), all critical processes remain under direct in-house QC control.
100% heat number mapping from raw steel plate to finalized pressure vessel shell.
Digital radiographic testing (RT), ultrasonic testing (UT), magnetic particle (MT), and liquid penetrant inspection (PT).
Calculations verified through finite element analysis (FEA) software for high-pressure limits.
