Most premature heat exchanger failures originate not in the tubes, but in the tube sheet.
Misalignment of orifices, poor expansion joints, stress concentration, and thermal fatigue all ultimately manifest as leaks at the tube ends, inability to maintain pressure, inability to repair, and forced shutdown.
The core value of the Tube Sheet Heat Exchanger is to make the sealing points the "safest place."
How do we make a "high-risk location" the "most stable structure"?
Tube sheets are not ordinary steel plates; they are pressure-bearing core components.
Our tube sheets are made from integral forgings or precision-machined high-strength thick plates. Finite element analysis simulates the distribution of thermal stress and loads, reserving stress release zones to reduce thermal fatigue concentration, ensuring the tube sheet remains stable under high temperature and pressure environments.
Holes are not "drilled," but "precision-machined."
Our tube sheet heat exchanger uses a CNC deep-hole machining center to complete all tube holes. Hole spacing, perpendicularity, and roundness are checked online, and each tube "naturally enters," not under forced correction.
This is one of the key processes determining the heat exchanger's lifespan.
Tube-to-tube sheet connections employ a double sealing system.
Precision-controlled expansion joints form the first metal seal.
Automatic welding forms the second structural seal.
Effectively resisting thermal cycling, vibration, and media corrosion.
Structural design directly serves future maintenance.
The tube bundle is removable.
The tube sheet has maintenance margins.
Cleaning, plugging, and replacement paths are planned during the design phase.
