Frequently Asked Questions
Q: What is ASTM A688 TP316/316L tube?
A: It's feedwater heater tubing designed for high corrosion resistance. The TP316/316L grade contains molybdenum, enhancing performance in chloride-rich environments compared to TP304L.
Q: TP316L vs TP304L—which is better?
A: TP316L outperforms in highly corrosive environments, especially with chlorides present. TP304L offers excellent value for moderate corrosion applications and costs less. Your environment dictates the best choice.
Q: What are typical applications?
A: Power plant feedwater systems, steam condensers, heat recovery units, and industrial heat exchangers where tube failure could compromise safety or production.
Q: Can you supply U-bent tubes?
A: Yes. We manufacture U-bent configurations to your specifications, reducing on-site bending requirements and installation time.
Q: What documentation do you provide?
A: Every shipment includes Material Test Certificates (MTC 3.1 or 3.2), dimensional reports, and additional documents like WPS/PQR or UT/RT reports upon request.
