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

The normalized state of these flanges is highly uniform. We found no grain issues during subsequent NDT testing, and they fit the shell perfectly.

Fully meets the rigorous requirements of TEMA R standards. We used these SA266 Grade 2N flanges for a refinery project in Texas. The machining precision is impressive, and the sealing face finish is absolutely perfect.

Robust construction suitable for our tough operating environment. The vessel handles our coal-to-liquid hydrogenation process with Fischer-Tropsch syncrude—highly corrosive service. The internal cladding overlay (E309L/E347) has shown zero defects after 18 months operation. We appreciate the comprehensive spare parts list and recommended maintenance schedule. The manufacturer even provided on-site supervision during our first catalyst loading. Good value for African market conditions.
