Ke kila kila 316Ti 1.4571
Pili kēia pepa ʻikepili i ke kila kila 316Ti / 1.4571 wela a me ke anu i ʻōwili ʻia a me ka ʻili, nā huahana semi-hoʻopau ʻia, nā kaola a me nā koʻokoʻo, uea a me nā ʻāpana e like me nā paipu seamless a welded no nā kumu kaomi.

ke kila kuhiliʻole 316TI paipu puʻupuʻu / puʻu capillary
ʻO ka hale kūkulu hale, nā puka, nā puka makani a me nā mea kaua, nā modula o waho o ke kahakai, ka ipu a me nā paipu no nā tankers kemika, hale kūʻai a me ka lawe ʻana i nā kemika, nā meaʻai a me nā mea inu, ka lāʻau lapaʻau, ka fiber synthetic, ka pepa a me nā mea kanu textile a me nā moku kaomi.Ma muli o ka Ti-alloy, kūpaʻa ke kū'ē i ka corrosion intergranular ma hope o ke kuʻi ʻana.
