Tube Bundle for Fixed Tube Sheet Exchanger Fixed Tube Sheet Bundle
Product Overview
We are a qualified pressure vessel manufacturer. The Tube Bundle for Fixed Tube Sheet Exchanger is a non-detachable integrated heat exchange assembly, consisting of shell, heat exchange tubes, tube sheets and baffles. Permanently welded as a whole, it is manufactured strictly following pressure vessel standards for industrial fixed heat exchange equipment.
Product Description
The Tube Bundle for Fixed Tube Sheet Exchanger is the indispensable core assembly of rigid tubular heat exchangers. Different from floating head tube bundles, the two end tube sheets are firmly fixed on the shell-side cylinder of the heat exchanger and are immovable. The internal baffles are arranged at equal intervals to stabilize the overall structure and enhance fluid turbulence.
Each welding joint adopts composite technology of tube expansion and welding to eliminate medium channeling between tube side and shell side. All metal parts undergo rust prevention treatment. Finished bundles pass hydraulic pressure test and air tightness inspection. This product effectively solves heat transfer attenuation, corrosion damage and scaling blockage of old tube bundles.

Core Advantages
1.Double-end fixed welding structure, high integral rigidity and strong vibration resistance
2.Precision expansion welding process, tight sealing without medium cross-leakage
3.Optimized baffle layout to improve turbulence and heat transfer efficiency
4.Anti-corrosion surface treatment, suitable for long-term continuous operation
5.Standard interchangeable size, convenient for direct equipment replacement
Packaging and Transportation
The tube bundle is polished and derusted. All pipe orifices are sealed with dust-proof plugs. The tube sheet and baffle surfaces are wrapped with shockproof foam. Reinforced wooden frames are used for outer packaging. Fixed binding prevents tube bending, collision deformation and dust contamination during long-distance transportation.
Applications
It is widely used for replacement and maintenance of fixed tube sheet heat exchangers in chemical, petroleum, heating and water treatment industries. It can be sold with expansion joints, gaskets and flanges. It has stable sales due to low replacement cost and strong versatility.

FAQ
Q: What is the structural feature of Fixed Tube Sheet Bundle?
A: It adopts tube sheet fixed welding structure without movable parts. The overall rigidity is higher than floating head bundles, featuring strong pressure resistance and stable structure, not easy to vibrate and deform.
Q: What working conditions is this tube bundle suitable for?
A: It is suitable for medium with low scaling rate and small temperature difference, such as industrial circulating water, clean oil and conventional chemical fluid. It is widely used in steady continuous production equipment.
Q: Why need to replace the old fixed tube sheet bundle?
A: Long-term medium scouring and corrosion will cause tube wall thinning, scaling accumulation and reduced heat transfer efficiency. Severe welding seam corrosion will lead to medium leakage, affecting normal production operation.
Q: Can this tube bundle be disassembled for cleaning?
A: It cannot be disassembled. The tube side can be cleaned by high-pressure water flushing, and the shell side adopts chemical circulating cleaning. It is not recommended for severely polluted and easy-scaling media.
Q: What qualification documents can you provide?
A: Provide material certificate, hydraulic test report and welding nondestructive testing report. 18-month warranty, with installation matching guidance and lifelong technical support.
