Chemical Composition of C46400
The C46400 alloy, known for its excellent corrosion resistance and thermal conductivity, is composed of the following elements:
| Element | Percentage (%) |
|---|---|
| Copper | 85.0 - 90.0 |
| Tin | 4.0 - 6.0 |
| Lead | 1.0 - 2.0 |
| Zinc | Balance |
Mechanical Properties of C46400
C46400 exhibits impressive mechanical properties, making it suitable for demanding applications:
| Property | Value |
|---|---|
| Tensile Strength | 310 MPa |
| Yield Strength | 210 MPa |
| Elongation | 30% |
Tube and Tube Sheet Welding
Welding of tubes to the tube sheet in shell and tube heat exchangers is critical for ensuring integrity and performance. The C46400 alloy can be welded using techniques such as TIG (Tungsten Inert Gas) or MIG (Metal Inert Gas) welding, which provide strong joints and minimal distortion.
Welding Inspection
Heat exchanger tube and tube plate welding and inspection
1. Pre-welding inspection.
- Dimensional tolerance test;.
- Cleanliness inspection
- Pipe projection height inspection;
- Spot weld inspection.
2. Welding inspection.
- Welding start and finish points.
- Welding specification checking.
- Depth of fusion and molding of the first pass and the second pass.
3. Post-welding inspection.
- Appearance and molding inspection of the weld.
- Gas tightness test (0.03~0.05MPa.) or helium leakage of pipe and tube joints.
- Surface MT or PT inspection
- Non-destructive radiographic inspection.
- Hydrostatic test.
