Key Construction & Material Specifications

Component	Typical Material Standard	Design Function & Advantage
Heat Exchanger Tubes	ASME SB213 TP316L	Seamless, low-carbon stainless steel offering excellent resistance to a wide range of corrosive chemicals and chloride pitting.
Tubesheets	ASME SA182 F316L (Fixed End) / SA266 Gr.2 (Floating End)	The floating end tubesheet is not welded to the shell, allowing free expansion. Materials are selected for weld compatibility.
Shell & Shell Cover	ASME SA516 Gr.70 or SA240 316L	Contains the shell-side fluid. Material is chosen based on process requirements.
Floating Head Assembly	Includes Cover, Gasket, & Bolting	Allows the tube bundle to expand and contract independently of the shell, eliminating thermal stress. Easily removable for maintenance.
Channel & Channel Cover	ASME SA516 Gr.70 or SA240 316L	Houses the tube-side inlet and outlet, allowing easy access to the tube ends for cleaning.
Baffles	ASME SA516 Gr.70 or SA240 316L	Support tubes and direct shell-side flow to maximize heat transfer efficiency.

Technical Highlights & Design Advantages

• ASME U Stamp Assurance: Every exchanger is designed, fabricated, inspected, and stamped in accordance with the ASME Boiler and Pressure Vessel Code, Section VIII, Division 1. This provides global recognition of safety, quality control, and material traceability.
• Stress-Free Thermal Expansion: The floating head design completely isolates the tube bundle from the shell, allowing unrestricted differential thermal expansion. This prevents stress buildup and is critical for high-temperature applications or large temperature differences.
• Superior Maintainability: The entire tube bundle can be withdrawn after removing the rear cover, granting full access to the external tube surfaces for mechanical cleaning, inspection, or tube replacement. This makes it ideal for services prone to fouling.
• Corrosion-Resistant Core: The use of TP316L stainless steel tubes provides a robust defense against a broad spectrum of corrosive process streams, ensuring longevity and reducing lifecycle costs.

Typical Applications & Value Proposition

• Versatile Process Solution: Ideal for refinery services, chemical processing, high-temperature heat recovery, viscous fluid heating/cooling, and other applications requiring easy maintenance and thermal flexibility.
• Reduced Lifecycle Costs: The design drastically reduces downtime for maintenance and cleaning. Combined with the durability of TP316L tubes, this results in lower total cost of ownership over the equipment's lifespan.
• Global Project Compliance: The ASME U Stamp ensures the unit meets the stringent requirements for projects worldwide, facilitating approvals and accelerating deployment.

This AES floating head exchanger combines TP316L tubes with a floating head design, giving you both corrosion resistance and the ability to handle significant temperature differences between shell and tube sides. The removable floating head and bundle mean tube inspection and cleaning can be done without disturbing shell piping, which keeps maintenance downtime low in refinery and chemical service. Shell and channel components are available in SA516 and SA266 carbon steel with stainless steel wetted parts, balancing cost and corrosion performance. ASME U Stamp, PED and CE certification, complete documentation and installation support are included.
