Yuhong Group, a Chinese manufacturer and exporter of steel pipes, tubes and heat exchanger components, has successfully completed and shipped a new batch of ASTM A213 T11 alloy steel seamless tubes for a heat exchanger project. The shipment left our factory on schedule, marking another milestone in our continuous support for the global power generation, petrochemical and refining industries.
Project Overview
ASTM A213 T11 is one of the most widely specified alloy steel grades for heat exchanger and boiler applications. It is a chromium-molybdenum alloy steel (1.25% Cr, 0.5% Mo) that offers an excellent balance of high-temperature strength, oxidation resistance and weldability, making it ideal for service temperatures up to approximately 550°C (1022°F).
The tubes supplied in this project were manufactured to meet the strictest international requirements, ensuring reliable long-term performance in demanding thermal cycling environments.

- Hydrostatic test – 100% pressure tested to ensure leak-free integrity
- Eddy current test – full-length non-destructive examination
- Dimensional inspection – OD, WT and length checked by third-party inspectors upon request
- Third-party inspection – SGS, BV, TUV or client-nominated inspectors welcome at any stage
Packaging and Shipping
Tubes were bundled with anti-rust treatment, wrapped in waterproof material and securely packed into seaworthy wooden crates for ocean freight. Loading was supervised by our QC team to ensure the cargo arrived in perfect condition. Thanks to our efficient production planning, the complete order was delivered strictly on schedule.
