At Yuhong Group Co., Ltd., we deliver custom, factory-tested skid-mounted process systems (Process Skid Packages) tailored for the oil & gas, petrochemical, refining, and energy industries. By integrating high-efficiency shell and tube heat exchangers, pressure vessels, air coolers, structural steel bases, and smart instrumentation, our turnkey skids provide plug-and-play field installation that drastically minimizes site labor and downtime.
In addition to complete skid manufacturing, we are a leading OEM supplier of high-precision internal replacement parts, including engineered u tube bundles, finned tube bundles, custom heat exchanger tubesheets, and forged structural accessories.
For technical specifications, engineering designs, or quotation inquiries, email us at jimmy@steelseamlesspipe.com.
A process skid (skid-mounted system) is a self-contained, block-fabricated equipment system mounted within a structural steel frame. Instead of assembling individual shell & tube heat exchangers, valves, pumps, and control systems on-site, Yuhong Group designs, fabricates, pipes, codes, and hydro-tests the entire system inside our advanced manufacturing facilities.
Our customized skids seamlessly integrate:
Shell and Tube Heat Exchanger units for severe temperature and pressure operations.
Modular cooling units featuring high-surface-area finned tube bundle assemblies.
Gas/liquid separators, filtration units, control valves, piping manifolds, and electrical wiring.
We engineer process skids suited for harsh environments, corrosive process fluids, and sour gas applications ($H_2S$ service adhering to NACE MR0175/ISO 15156):
Gas Conditioning & Fuel Gas Regulating Skids: Utilizes custom u tube bundle heat exchangers for gas preheating and liquid separation.
Oil & Gas Separation & Metering Skids: Integrated with high-pressure separators and precision flow loops.
Chemical Injection & Heat Recovery Skids: Modular units incorporating specialized alloy shell and tube heat exchangers for maximum energy recovery.
Air-Cooled Heat Exchanger Skids: Features heavy-duty finned tube bundle modules for offshore and desert environments with scarce water resources.
Carbon Steel: ASTM A106 Gr. B, A516 Gr. 70 (HIC/SOHIC resistant grades available).
Stainless Steel: Austenitic 304/304L, 316/316L, 321, 347H for chemical resistance.
Duplex & Super Duplex: S31803 (2205), S32750 (2507) for marine, brine, and high-chloride environments.
Nickel Alloys: Inconel 625, Incoloy 825, Hastelloy C276 for extreme sour crude and elevated temperature loops.
Whether ordering a complete skid or sourcing replacement parts for plant turnarounds, our component manufacturing capacity covers all critical items:
| Skid & Heat Exchanger Component | Technical Function & Role in System | Available Material & Design Standards |
| U Tube Bundle / Straight Tube Bundle | The primary thermal transfer core in the shell and tube heat exchanger; handles expansion naturally without expansion joints. | Stainless Steel, Nickel Alloys, Duplex, Carbon Steel (ASME Sec VIII / TEMA Class R, C, B) |
| Finned Tube Bundle | Expands external heat transfer surface area significantly for forced-draft or induced-draft air cooling modules. | Extruded Aluminium Fins, KL-Fin, L-Fin, Embedded G-Fin on Seamless Base Tubes |
| Heat Exchanger Tubesheet | Heavy forged disk securing the tube bundle; precision-drilled via multi-axis CNC machines to prevent cross-leakage. | Forged Carbon Steel, Stainless Steel Clad, Solid Alloy Forgings (SA266, SA336) |
| Baffles & Tie Rods | Directs fluid flow across tube passes to eliminate dead zones, optimize heat transfer, and prevent flow-induced vibration. | Carbon Steel, 316L Stainless Steel, Brass, Anti-vibration Rod Baffles |
| Valves, Manifolds & Instrumentation | Regulates pressure, temperature, and fluid routing across the skid package automatically via PLC/DCS interfaces. | Flanged or Welded Globe, Ball, Check Valves; Smart Transmitter Arrays |
| Structural Steel Base Frame | Heavy I-beam/channel frame engineered to withstand lifting, sea transport, wind loads, and operational vibration. | ASTM A36, Structural Carbon Steel with Epoxy or Marine-grade Coatings |
Plug-and-Play Installation: Pre-wired, pre-piped, and factory-tested units eliminate up to 80% of field assembly time and labor costs.
Uncompromising Quality Control: Every u tube bundle and heat exchanger tubesheet undergoes strict non-destructive testing (NDT), including RT, UT, MT, and Hydro-static testing prior to skid mounting.
Minimized Plant Footprint: Compact, 3D-modeled multi-tier designs save valuable plot space in refineries and offshore platforms.
Single-Source Accountability: From raw seamless piping and finned tube bundle fabrication to skid structural welding, Yuhong Group manages the complete value chain.
In skid units carrying high-velocity multiphase fluids, piping and tube bundle vibration can cause joint cracking or flange leaks.
Solution: Yuhong applies finite element analysis (FEA) and flow-induced vibration assessment during design. We incorporate heavy-duty clamp supports and specialized baffle structures inside our shell & tube heat exchangers.
Because process piping and exchanger shells operate at higher temperatures than the structural base frame, thermal growth must be accommodated.
Solution: Slotted bolt holes, sliding saddles, and flexible piping loops are integrated to absorb axial and radial movement, extending seal life on the heat exchanger tubesheet.
Comprehensive OEM Capabilities: Supplying both full-scale modular skids and replacement tube bundles for quick delivery during plant maintenance turnarounds.
International Standards Compliance: ASME Code Stamped, TEMA Certified, PED compliant, and API compliant.
Global Shipping Experience: Fully boxed, protected, and sea-worthy transport preparations for safe arrival at overseas job sites.
