Heat Exchanger Tube ASTM B677 TP904L SMLS Tube
ASTM B677 TP904L Seamless (SMLS) Tubes are high-performance austenitic stainless steel tubes specifically designed for heat exchanger applications in industries requiring excellent corrosion resistance and durability. These tubes conform to the ASTM B677 standard, which specifies seamless stainless steel tubing, and are made from TP904L, a low-carbon, high-alloy stainless steel grade.
Key Features of TP904L Seamless Tubes:
1. Material Composition:
TP904L is a super austenitic stainless steel alloy with high levels of chromium (19-23%), nickel (23-28%), molybdenum (4-5%), and copper (1-2%). This composition provides outstanding resistance to corrosion, particularly in environments with strong acids like sulfuric, phosphoric, and acetic acids.
2. Seamless Construction:
The seamless (SMLS) design ensures uniform strength and eliminates the risk of weak points in the tube, making it highly reliable for high-pressure and high-temperature applications.
3. High Corrosion Resistance:
TP904L offers excellent resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC), especially in chloride-rich environments.
4. Heat Resistance:
These tubes perform well at elevated temperatures, maintaining structural integrity and corrosion resistance in heat exchanger applications.
5. ASTM B677 Standard Compliance:
Tubes produced under this standard undergo stringent quality control, ensuring precise dimensions, superior mechanical properties, and excellent surface finish.
Chemical Composition:
| Grade | Ni | Cr | Mo | Mn |
| ASTM B677 TP904L | 23.0 – 28.0 | 19.0 – 23.0 | 4.0 – 5.0 | ≤ 2.00 |
Mechanical Properties:
| Grade | Yield Strength | Tensile Strength | Elongation |
| ASTM B677 TP904L | Approximately 215 MPa (31 ksi) | Approximately 490 MPa (71 ksi) | 35% |
Common Applications:
· Chemical Processing: Used in heat exchangers, condensers, and reactors exposed to corrosive acids and chemicals.
· Oil and Gas Industry: Ideal for offshore platforms, desalination plants, and other chloride-rich environments.
· Power Generation: Suitable for heat exchangers in power plants dealing with high temperatures and corrosive fluids.
· Fertilizer Industry: Used in urea plants and other aggressive chemical applications.
· Pharmaceutical and Food Industries: For equipment requiring high corrosion resistance and contamination-free operation.
