1. Features
1.1. Low-pressure resistant design:
Use special materials (such as alloy steel, stainless steel) and thickened shell or tube wall to withstand working pressure up to tens of MPa.
1.2. Efficient heat transfer:
By optimizing the heat exchange structure (such as bellows or spiral flow channel design), the heat exchange efficiency is improved while minimizing the equipment volume.
1.3. Reliable sealing performance:
Use high-performance seals or welding technology to prevent medium leakage under high pressure.
1.4. Strong corrosion resistance:
It is often necessary to deal with corrosive media, and corrosion-resistant materials (such as titanium alloy, nickel-based alloy) are usually selected.
