Product Description
U-Tube heat exchanger tubes are stainless steel tubes bent into a U-shape for use in shell and tube heat exchangers. This design allows for thermal expansion compensation, easy tube bundle removal, and efficient heat transfer. Manufactured from seamless or welded stainless steel, these tubes offer excellent corrosion resistance and high reliability in demanding thermal applications.
Key Features:
Precision U-bending with consistent radius
Allows free thermal expansion – no stress on tube sheet
Easy maintenance – the tube bundle can be removed and cleaned
Smooth internal surface for optimal heat transfer
Available in various bend radii and leg lengths
Seamless or welded & drawn construction
