Pipe sans couture (1)
WT: 0,5-120 mm
Longueur: 3-16m
Application: Pétrole, génie chimique, électricité, chaudière
Norme: ASTM A335 / A335M, ASTM A213 / 213M, DIN17175-79, JIS3467-88, GB5310-95
Matériel: P5, T5, P11, P12, STFA22, P22, T91, T9, WB36
Le tuyau en alliage est une sorte de tuyau en acier sans couture, ses performances sont beaucoup plus élevées que celles du tuyau en acier général sans couture, car ce type de tuyau en acier contient plus de Cr, sa résistance à haute température, sa résistance à basse température, ses performances de résistance à la corrosion est bien meilleure que les autres Tuyau en acier, de sorte que le tuyau en alliage est largement utilisé dans les industries du pétrole, de l'aérospatiale, des produits chimiques, de l'énergie électrique, de la chaudière, des militaires et d'autres.
