Carbon Steel ASTM A333 GR.1 Low Fin Tube For Economizers and Oil Coolers

Carbon Steel A333 GR.1 Base Tube

Mechanical Properties:

• Tensile Strength: ≥380 MPa (55 ksi)
• Yield Strength: ≥205 MPa (30 ksi)
• Elongation: ≥35% (longitudinal), ≥25% (transverse)
• Impact Toughness:
• Charpy V-Notch impact energy ≥18 J at -45°C.
• Designed to prevent brittle fracture in low-temperature environments.

A333 GR.1 Low Fin Tube Application

A333 GR.1 Low Fin Tube Strength
Pressure Resistance: Suitable for high-pressure applications (e.g., shell-and-tube heat exchangers) due to seamless base tube and robust fin design.
Thermal Strength: Maintains stability in temperatures from -45°C to ~425°C (carbon steel limit).
Low fins enhance heat transfer efficiency by 1.5–3 times compared to smooth tubes, reducing thermal stress.
Corrosion and Fouling Resistance:Low fin spacing reduces fouling, extending service life by 30% in viscous fluids (e.g., hydrocarbons).
Compatible with corrosive environments when clad with stainless steel or alloys.

Conclusion: Why Choose A333 GR.1 Low Fin Tube?
You would select an A333 Gr.1 Low Fin Tube when you need:

• High Efficiency with Liquids: For duties involving viscous liquids, hydrocarbons, or refrigerants where heat transfer is the limiting factor.
• Reliability in Cold Service: For applications operating below ambient temperature down to -45°C, where material toughness is non-negotiable.
• Reduced Operating Costs: To save on energy and maintenance costs over the long term, justifying the higher initial investment.
• Space Constraints: To maximize heat transfer in a limited physical footprint.
