Typical Specifications
Core Description
Heat Exchange Area
1㎡ – 5000㎡
Non-standard area customizable, covering lab testing to large scale industrial production
Design Pressure
-0.1MPa ~ 35MPa
Adapts to vacuum, atmospheric, and high pressure conditions for steam, oil, gas, and chemical media
Design Temperature
-200℃ ~ 600℃
Adjustable based on medium type (thermal oil / steam / process fluid) and process requirements
Main Material
Carbon steel, 304/316L stainless steel, titanium, Hastelloy, nickel based alloy
Matches extreme conditions of strong corrosion, high temperature, and high pressure for durable service
Structure Type
Fixed tube sheet, floating head, U tube
Floating head / U tube relieves thermal expansion stress for large temperature differences; fixed tube sheet offers lower cost
Tube Specification
Φ12–50mm, length 1–12m
Smaller diameter delivers higher efficiency; longer tubes reduce footprint
Heat Transfer Coefficient
Water water: 800–2000 W/(m²·K)Gas water: 50–300 W/(m²·K)
Corrugated / double wall tubes improve efficiency by over 20%
Sealing Type
Gasket seal, welded seal, expanded seal
Welded / expanded + gasket combination ensures zero leakage for flammable and explosive media
