We offer ASME Certified Forged Tube and Plate Round Cake in ASME SB171 C61400 designed for heat exchanger applications in accordance with ASME Section VIII and TEMA standards. This product has excellent corrosion resistance and mechanical properties and is particularly suitable for heat exchanger equipment in seawater, brine and aggressive chemical media. Our forged tube sheet discs are manufactured in strict accordance with international norms and undergo comprehensive non-destructive testing to ensure high quality and reliability.
C61400 is an aluminum-bronze alloy widely used in heat exchangers and marine equipment. It complies with ASME SB171 standards and has the following features:
| attribute | description |
|---|---|
| Key Ingredients: | Copper (Cu 83-87%), Aluminum (Al 6.0-8.5%), Iron (Fe 2.0-4.0%) |
| Corrosion resistance | It has strong corrosion resistance to seawater, salt water, acidic and alkaline liquids, and is especially suitable for preventing pitting and crack corrosion. |
| Mechanical properties | High strength and good performance, with a tensile strength of 485 MPa and a yield strength of ≥ 170 MPa. |
| Thermal conductivity | Good conductivity and conductivity for heat exchanger applications. |
| weldability | Good welding performance, easy to process and assemble. |
Forged tube plate discs need to pass strict non-destructive testing before delivery to ensure material quality and safety in use. The following are the main non-destructive testing methods:
| Detection method | objective | Standard reference |
|---|---|---|
| Probe Detection (UT) | Check the material for defects such as cracks, delamination, and porosity | ASME Volume V |
| Magnetic Particle Detection (MT) | Detects surface and near-surface defects, such as cracks and inclusions | ASME Volume V |
| Staining Penetrant Testing (PT) | It is used to detect surface opening defects, such as cracks, holes | ASME Volume V |
| Dimensional inspection | Ensure that the diameter, thickness and tolerance of the disc meet the requirements of the drawing | ASME Section VIII and Customer Requirements |
