["Ich habe diese neue Normung noch nicht gründlich untersucht, aber nacherererst einmal einenschauend, scheint es sich um die Berechnungsformel für den Drucktestobereich von DL/T 5854--2216 zu handeln. Die周向应力有可能是引用DL/T 5854--2216 公式3.3.3-3 纵向应力有可能是引用DL/T 5854--2216 公式3 pérdida3.3.4. Die zulendliche Druckbelastigung für industrielle Rohre wird nach GB/T 281的来规定，因为两个规范的许用应力值不一样。"
