Product Description
AES Type Heat Exchanger for Oil Refinery Service
ASME SA179 Tube Bundle & SA266 Gr.2N Tubesheet Robust Process Design
Yuhong Group: Engineering Critical Equipment for the Energy Sector
Yuhong Group Co., Ltd. provides engineered solutions for demanding industrial processes. Our expertise covers the design, fabrication, and supply of ASME-coded shell and tube heat exchangers, pressure vessels, and their vital components. We specialize in replacement tube bundles, U-tubes, heat exchanger tubes, and all associated parts including tubesheets, baffles, and channel heads, with a focus on reliability in severe service environments.
Product Profile: AES Heat Exchanger for Refinery Applications
The AES Type (floating head) heat exchanger is a workhorse design in oil refineries, valued for its ability to handle thermal expansion and facilitate maintenance. This unit features a replaceable tube bundle constructed with ASME SA179 carbon steel tubes and a sturdy SA266 Grade 2 Normalized (Gr.2N) carbon steel tubesheet, making it a durable and cost-effective solution for various refinery heating, cooling, and condensation duties.
Key Construction & Component Details
Major Assembly Specification / Material Function & Refinery-Specific Rationale
Removable Tube Bundle Tubes: ASME SA179 Allows for easy replacement during turnaround. SA179 tubes offer good heat transfer for hydrocarbons, water, and steam services.
Stationary & Floating Tubesheets ASME SA266 Gr.2N (Normalized) The normalized heat treatment provides improved and more uniform mechanical properties (strength, toughness) for reliable performance under thermal cycling.
Shell & Floating Head Assembly Shell: SA516 Gr.70; Head Assembly: Gasketed The floating head accommodates differential expansion between shell and tubes, a common occurrence in refinery temperature swings.
Baffle System SA516 Gr.70 Configurable (single/double segmental) to manage shell-side flow of refinery streams (crude, residues, etc.) and minimize fouling.
Channel & Cover SA516 Gr.70 or SA105 Provides access to tube ends for inspection and cleaning without disturbing shell-side piping.
Technical Focus: Why AES Heat Exchangers Excel in Refineries
The AES type (Rear Head Removable Floating Head Heat Exchanger) is a classic design specified in the TEMA standards. Its widespread adoption in refineries stems from several key engineering advantages:
  • Thermal Stress Resistance: Refining processes involve intense temperature fluctuations. The floating head design allows the tube bundle to expand and contract freely, avoiding destructive thermal stress caused by excessive temperature differences.
  • Easy Maintenance and Cleaning: Refining feedstocks are prone to fouling. The AES design enables the entire tube bundle to be withdrawn, facilitating thorough mechanical cleaning and significantly shortening maintenance downtime.
  • Versatile Fluid Handling: Features a wide design pressure and temperature range, making it suitable for heat exchange requirements of various refining fluids, from light naphtha to heavy residual oil.
Core Advantages and Customized Engineering Services
  • Optimized for Refining Conditions: Material selection and design parameters are tailored to refining fluid characteristics to balance heat transfer efficiency and equipment service life.
  • Maximized Operational Uptime: The removable tube bundle design minimizes production impact during scheduled maintenance, aligning with rigorous turnaround planning schedules.
  • Flexible Engineering Adaptation: We perform thermal and hydraulic calculations based on your specific process data to optimize tube bundle and baffle design.
  • Total Cost of Ownership Advantage: Reasonable initial investment combined with easy-to-maintain design delivers excellent long-term value.
Typical Refinery Applications
  • Crude oil preheating networks
  • Overhead distillate condensers or coolers
  • Product coolers (diesel, vacuum gas oil)
  • Coolers for lubricating oil and seal oil systems
  • Heavy oil heaters or heat exchangers

We installed this heat exchanger at our petrochemical facility in Jubail Industrial City back in March. The ASME VIII-1 certification was non-negotiable for us, and this unit delivered exactly what we needed. The SA516 Gr485 shell material has held up exceptionally well against our high-temperature process streams, even during the peak summer months when ambient temperatures exceed 45°C. What impressed me most was the quality of the welding—our inspection team did radiography testing on random seams, and all passed with flying colors. The supplier kept us updated throughout fabrication with photos and progress reports, which built a lot of trust. We've had zero leaks or performance issues since startup. Definitely planning to order another unit for our expansion project next year.

We purchased this heat exchanger for a critical amine service in our Texas plant. The ASME VIII-1 stamp gave us the confidence we needed for regulatory compliance. Upon arrival, our third-party inspector did a thorough check—he was impressed by the weld quality and the precise thickness of the SA516 Gr485 shell. It's been running continuously for six months now with zero issues. The documentation package (including material test reports and NDT reports) was complete and well-organized. Definitely a supplier we'll consider for future expansions.
