4. Key Features & Advantages
High-Temperature Resistance: Suitable for up to 1150°C (continuous use).
Corrosion Resistance: Excellent resistance to oxidation, sulfidation, and acidic environments.
Seamless Design: No welds, ensuring leak-proof performance under high pressure (up to 30 MPa).
Certified Quality: Complies with ASTM A312, ASME SA312, EN 10216-5, and JIS G3459.
Q: How does TP310S compare to standard 304/316 tubes? A: TP310S has higher Cr/Ni content, offering 3x better oxidation resistance at temperatures above 800°C.
Q: Can you supply custom sizes? A: Yes! We support OD: 6–1200mm, thickness: 0.5–50mm, and lengths up to 18m.
