Floating Head Assembly for Heat Exchanger Floating Head Assembly Heat Exchanger Head
Product Overview
We are a qualified pressure vessel manufacturer. The floating head assembly is a movable sealing component installed at the floating end of shell and tube heat exchangers. It independently bears tube-side pressure and compensates for thermal expansion, manufactured in strict accordance with pressure vessel codes to ensure high-temperature operation safety.
Products Description
The floating head assembly consists of floating head cover, sealing gaskets, fasteners and pressure rings. It is specially designed for floating head heat exchangers. Different from fixed components, this movable structure can slide freely inside the shell to offset thermal expansion difference between tube bundle and shell.
The floating head separates tube-side and shell-side medium without external leakage. High-quality anti-corrosion gaskets are adopted for durable sealing. Each assembly passes hydraulic pressure test and tightness inspection, solving tube bundle cracking and leakage caused by high-temperature thermal stress.

FAQ
Q: What is the main function of the floating head assembly?
A: It compensates the thermal expansion difference between the tube bundle and the shell, eliminates thermal stress, isolates two media, and prevents leakage. It is the key movable part of floating head heat exchangers.
Q: What is the difference between floating head and fixed tube sheet structure?
A: The floating head can move freely to adapt to high temperature difference; the fixed structure cannot expand and contract, which is easy to crack under high temperature. Floating head type is more suitable for harsh high-temperature working conditions.
Q: Why does the floating head assembly leak?
A: Long-term high temperature aging of gaskets, uneven sealing surface, loose fasteners and thermal deformation will cause medium leakage. Regular replacement of assembly accessories ensures tightness.
Q: Can you customize non-standard floating head components?
A: Yes. We support customized diameter, pressure grade, material and sealing structure according to drawings, which is compatible with various old floating head heat exchangers for replacement.
Q: What qualification documents can be provided?
A: Provide material certificate, hydraulic test report and forging inspection report.
