Our ASME SA240 TP304 Tubesheet is a critical component for shell and tube heat exchangers, designed to support and secure the heat exchanger tubes while ensuring optimal thermal performance and mechanical stability. Manufactured in compliance with the ASME Boiler and Pressure Vessel Code, this tubesheet is made from SA240 TP304 stainless steel, ensuring superior resistance to corrosion, durability, and reliability. Each tubesheet undergoes PT (Penetrant Testing) to ensure it is free of surface defects and meets the highest quality standards.
ASME SA266 TP304 High-Pressure Tubesheet Chemical Composition
The SA240 TP304 stainless steel is an austenitic stainless steel known for its excellent corrosion resistance and mechanical properties. Below is the chemical composition of TP304:
| Element | Composition (%) |
| Carbon (C) | ≤ 0.08 |
| Manganese (Mn) | ≤ 2.00 |
| Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.030 |
| Silicon (Si) | ≤ 0.75 |
| Chromium (Cr) | 18.0 - 20.0 |
| Nickel (Ni) | 8.0 - 10.5 |
This composition provides TP304 with excellent resistance to oxidation, corrosion, and chemical exposure, making it ideal for heat exchanger applications.
ASME SA266 TP304 High-Pressure Tubesheet Mechanical Properties
