Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. was established in June 2021 with a registered capital of 78 million yuan. Located in the high-tech industrial hub of the Sanhe Economic Development Zone, Langfang City, we focus on the R&D, custom design, and precision manufacturing of industrial pressure vessels, multi-stage filter housing systems, and environmental recovery machinery.
Our comprehensive production facility holds the A2 level pressure vessel manufacturing license, pressure pipeline component manufacturing license, ISO9001/GB/T19001-2016 quality system certification, and the prestigious Sinopec HSSE / China Petroleum Health, Safety, and Environment Management System certifications. As a recognized municipal R&D platform, we combine academic excellence from Tsinghua University and the Chinese Academy of Sciences (CAS) to deliver robust engineering upgrades.
Our primary capabilities extend across environmental protection equipment, industrial refrigeration (-40℃ to -180℃), coalbed methane/natural gas purification, VOC mitigation, BOG helium extraction, and custom pressure filter vessels engineered to handle corrosive, high-pressure, and thermal-extreme applications.

Why global enterprises source industrial-grade pressure vessel housings from Hebei Hongke Qingneng.
Utilizing Finite Element Analysis (FEA) and PV Elite design platforms, we simulate extreme thermal, pressure, and wind loads. This guarantees our filter housings withstand high cyclic loads in refineries and petrochemical plants.
Our ASME-equivalent A2 level certification ensures structural integrity. Every welded seam on our carbon steel, SS304, or SS316L housings undergoes Non-Destructive Testing (RT/UT/MT/PT) and hydrostatic pressure verification.
Located in the Langfang Industrial Corridor adjacent to major steel mills and international ports (Tianjin), we secure high-grade raw materials at optimized rates. This allows us to offer cost-competitive manufacturing cycles without compromising on alloy purity.
How our advanced filter vessels and skid systems resolve critical industrial challenges globally.
Filter housings play an essential role in preventing catalytic bed fouling, turbine blade erosion, and valve blockages in gas pipelines. Our customized separators and coalescer housings filter out fine rust, liquid hydrocarbons, and moisture from raw shale gas or coalbed methane prior to cryogenic liquefaction.
High-temperature steam sterilization releases corrosive gases, heavy vapors, and particulates. Our heavy-walled filter vessels act as primary separation units in mobile and centralized medical waste plants, isolating volatile organics and bio-contaminants at temperatures exceeding 134°C.
Our multi-stage exhaust gas purification skids integrate custom vessels filled with structured adsorbents and high-efficiency particulate coalescers, effectively removing 99.9% of VOC emissions in chemical tail gas processing lines.
The shift towards smart, durable, and highly compliant process vessels.
Global industrial sectors are under intense pressure to decarbonize, reduce fugitive emissions, and enhance energy conservation. In response, modern filter housing engineering has evolved beyond standard vessels to encompass smart-monitoring capabilities and advanced alloy materials. At Hebei Hongke Qingneng, our R&D team addresses these shifts by redesigning vessels with integrated differential pressure sensors, hydraulic quick-opening closures, and duplex stainless-steel linings.
Whether for high-purity natural gas filtration, hydrogen blending lines, or industrial-scale cold traps, the selection of the filter housing dictates the efficiency of the entire process loop. Key design parameters such as gas velocity, flow path dynamics, and shell corrosion allowances are calculated using advanced software to eliminate thermal stress zones and bypass routes.
Furthermore, as plants move toward modular skid-mounted systems, filter housings must be compact yet capable of handling extremely high throughputs. By designing bespoke shell and tube heat exchangers and non-standard pressure vessels that integrate filtration directly within processing skids, we save up to 35% footprint space for offshore and remote gas-field setups.
Real-world deployments proving the durability and efficiency of our engineering.
Answering the core questions that procurement managers, pipeline designers, and compliance engineers ask during vetting.
An A2 level pressure vessel manufacturing license is a statutory qualification under Chinese regulations (GB/T standards) indicating that the factory is certified to design, fabricate, and test medium-to-high pressure vessels. This is comparable to ASME Section VIII Division 1 certification. Working with an A2-certified factory like Hebei Hongke Qingneng ensures that all structural welding, heat treatment, raw material trace certifications, and pressure testing protocols are legally audited by third parties and verified for high-risk gas/chemical environments.
We work with high-grade alloys, including Stainless Steel 304, 316L, Duplex Stainless Steels (such as S32205/S31803), and Hastelloy when required. Our engineering team calculates precise corrosion allowances based on the stream composition (e.g., presence of H2S, CO2, chlorides) and fluid velocity to prevent stress corrosion cracking and pitting. All internal housing surfaces can undergo passivation, pickling, or electro-polishing to match high-purity specifications.
We specialize in custom sizing, high-pressure ratings (up to 30 MPa and higher depending on the application), quick-opening design closures (e.g., band clamps, swing bolts, segment rings), and multiple nozzle orientations to fit existing site footprints. We also integrate support structures, platforms, clean-in-place (CIP) connections, thermal jackets, and sensor pockets for real-time differential pressure (DP) and temperature tracking.
Yes. Guided by researchers from Tsinghua University and the Chinese Academy of Sciences, we have designed and delivered over 50 modular skid projects, including LNG liquefaction plants, coalbed methane purification systems, and mobile waste treatment units. We construct and wire the entire skid (valves, instrumentation, filters, heat exchangers, PLC control panels) at our factory, performing comprehensive structural and functional testing before shipping for rapid plug-and-play installation on-site.
Each custom vessel and filtration skid is delivered with a complete quality assurance dossier. This includes raw material Mill Test Certificates (MTCs), welding procedure specifications (WPS) and procedure qualification records (PQR), welder certificates, Non-Destructive Testing reports (NDT - RT/UT/PT/MT), paint thickness testing, hydrostatic test charts, and third-party inspection reports (where applicable) to satisfy import customs and plant safety audits.
