Standaard wanddikte
· Nominale wanddikte van pijpen: e = K (0.5 + 0.001 * DN)
· Waar, DN: nominale diameter; K: coëfficiënt (K = 7, 8, 9, 10, 11, 12-)
· Nominale wanddikte van buisleidingen:
· E = 7 + 0.014 * DN (K = 14)
· E = 6 + 0.012 * DN (K = 12)
· Nominale ijzeren wanddikte ≤ 6, de grensafwijking van de nominale wanddikte is -1,3
· Nominale ijzeren wanddikte> 6, de grensafwijking van de nominale wanddikte is - (1.3+ 0.001DN)
Belangrijkste toepassingen van nodulair gietijzer buizen
· Watertoevoerleiding en gasleiding
· De overdracht van corrosiebestendige materialen
· Op grote schaal gebruikt in de stedelijke watervoorziening, drainage, gas engineering
