Authored by drafting participant Yuantai Derun, this guide breaks down core revisions: consolidated 6728+6723 frameworks, new laser cutting & mechanical property requirements, and revised Appendix B tolerances & galvanizing re-inspection rules. Get free PDF downloads of the official Chinese, English, and bilingual texts, plus grade mapping to EN 10219 & ASTM A500.
- EN 10255 vs ASTM A53 vs BS 1387: Cross-Reference Guide for Pipe SelectionJun 11,2026Compare EN 10255, ASTM A53 & BS 1387 steel pipes. Explore critical differences in dimensional tolerances, threading requirements, and multi-standard mill compliance.
- 1550x1550x80mm Heavy Wall Hollow Sections | YuantaiJun 8,2026Technical insights on manufacturing ultra-large 1550x1550x80mm square steel pipes using JCOE & Round-to-Square processes from Yuantai Derun.
- 10ga vs 3.4mm: The Steel Gauge Procurement TrapMay 6,2026The "Gauge Trap" causes costly steel procurement errors due to standard fragmentation. To ensure integrity, replace vague labels with exact metric values and ASTM standards. Always specify structural grades like ASTM A572 over merchant quality A575, as thickness alone doesn't guarantee strength. Finally, verify quality by measuring away from deformed cut edges with perpendicular calipers and using QR-based digital traceability.
- Steel Pipe Thickness: Avoid the 0.1mm Burr TrapApr 30,2026Most wall thickness readings are wrong by up to 0.3mm. It’s rarely a production issue—it’s the 'Burr Trap.' If you measure directly at the cut edge, you're measuring scrap metal, not the pipe. In this technical breakdown, we look at the exact QC protocols used at Yuantai Derun, from the 20mm offset rule to digital MTC verification, to ensure your 11 Gauge specs are 100% accurate.
- Can You Use Galvanized Pipe for Gas? What Every Contractor Should KnowApr 23,2026If you walk onto a job site and ask two plumbers whether you can use galvanized pipe for gas lines, you’ll likely get two different answers. Some will swear it’s a hazard; others will tell you they’ve been doing it for decades.
- Why Upgrade to High Strength Steel S275 to S960?Apr 17,2026Building "bigger" with more steel is dead. In 2026, HSS and UHSS are the essential bypass to bloated, high-carbon designs. By leaning out the structural skeleton, these materials reduce environmental impact while significantly lowering foundation and logistics overhead. Efficiency is the new strength.
- Are You Ignoring 11 Gauge Steel's Secrets?Apr 15,2026When you order 11 Gauge (3.0mm) structural steel, you aren’t just buying a thickness; you’re buying a personality. In the steel world, 11 gauge sits in a "Goldilocks zone"—too thick to be treated like sheet metal, yet too thin to behave like heavy plate.
