Why Helical Geometries out-perform straight shell-and-tube configurations in critical applications.
The helical coil path induces centrifugal forces on fluid particles, creating transverse Dean vortices. This boundary-layer disruption yields heat transfer coefficients 1.5 to 2.8 times higher than straight tubes.
The inherent flexibility of coiled configurations allows helical bundles to absorb severe thermal shocks and cycling (-196°C to +300°C) without joint fatigue, critical in cryogenic LNG and deacidification systems.
High surface area-to-volume density enables smaller containment footprints, allowing for skid-mounted modules that simplify transportation and minimize site installation costs.
Deploying advanced Euler-Euler CFD numerical simulations to accurately predict fluid phase transitions inside helical geometries, reducing pressure drops by 15%.
Adopting automated plasma welding for high-strength Super Duplex stainless steel and nickel alloys to improve H₂S corrosion resistance in sour gas processing plants.
Integrating real-time thermal sensors within helical headers to continuously monitor heat flux and predict fouling layers, maximizing operational uptime.
Our competitive advantage lies in the translation of advanced engineering sciences into reliable, heavy-duty industrial systems.

Senior Engineer specializing in structural flow design and scale-up models. Published 24 academic papers (11 SCI/EI indexed) and holds 5 patents. Spearheaded high-capacity skid-mounted natural gas liquefaction plant markets in China, securing the Technological Invention Award Special Prize (2015) and the 19th China International Industry Expo Silver Medal (2017).
Doctor of Engineering from CAS, specialized in phase-change heat transfer mechanisms and multi-component mixtures flow patterns. Key architect of the "Technology Development and Application of Skid-mounted Natural Gas Liquefaction Unit". Awarded the Beijing Science and Technology Award First Prize. Oversees thermodynamic simulation, mechanical optimization, and manufacturing lines.
Procurement managers in Europe and North America demand adherence to ASME Section VIII Div 1/2, CE-PED, and local environmental standards. We align our manufacturing processes to meet these criteria, performing RT (Radiographic Testing), UT (Ultrasonic Testing), and hydrostatic pressure tests for every custom-fabricated helical heat exchanger and pressure vessel before shipment.
Minimizing on-site engineering is key for remote operations, such as shale gas extraction in North America or gas recovery in Central Asia. Our pre-fabricated, skid-mounted gas treatment and liquefaction units are fully assembled and tested at our facility. This structural modularity reduces site work to basic hookups, accelerating time-to-market.
Processing sour gas containing H₂S and CO₂ calls for careful corrosion management. By utilizing premium alloys (such as SS316L, Duplex 2205, and Hastelloy), our purification and desulphurisation plants deliver stable service lifetimes, preventing flow-induced vibration and hydrogen embrittlement.
Our custom systems deliver performance across demanding industrial environments.
High-spec engineering solutions designed to meet specific process parameters and emissions standards.
Addressing critical engineering and sourcing questions from project operators.
In cryogenic LNG applications (operating down to -162°C or lower), temperature changes can cause significant thermal stress. Helical coil designs allow individual tubes to expand and contract independently, minimizing mechanical stress at tube sheets. The secondary vortex flow within the coils also increases heat transfer on the tube side, helping to achieve sub-cooling inside a compact skid footprint.
Our Quality Management System operates in compliance with GB/T19001-2016 and standard ASME guidelines. We perform non-destructive testing (NDT), including visual inspection, liquid penetrant testing (PT), ultrasonic testing (UT), and radiographic testing (RT) for load-bearing welds. Final validation is carried out via hydrostatic pressure testing to confirm structural sealing and meet pressure limits.
Yes. Our purification modules include custom absorption, deacidification, and desulphurisation towers. Depending on the input gas properties, we utilize specific wet processes or dry bed scrubbers made from erosion-resistant stainless steel or cladding alloys. This prevents corrosion and helps lower H₂S levels to meet pipeline specifications.
We manufacture industrial refrigeration and process chiller units with operating temperatures ranging from -40°C down to -180°C. These systems are used in applications such as vacuum cold traps (-135°C), deep freeze dryers, BOG gas recovery, and helium extraction systems.
We manufacture both centralized facilities and trailer-mounted mobile units. These systems utilize high-temperature steam sterilization (operating at 134°C to 140°C under high pressure) to process pathological waste, laboratory animal tissue, and medical plastics, complying with global public health and biosecurity regulations.
Collaborate with our CAS doctoral team to design, simulate, and fabricate custom helical heat exchangers, cryogenic pressure vessels, or skid-mounted liquefaction equipment tailored to your exact process specs.
