12Cr1MoVG kiʻekiʻe puʻe kila paipu maikaʻi
Hoʻonui ʻia ke kahua noi o 12Cr1MoVG alloy pipe e hāʻawi i kahi ākea ākea no ka hoʻomohala ʻana i ka ʻoihana. Wahi a ka noiʻi ʻana o 12Cr1MoVG alloy pipe lālā o Kina Special Steel Association, e hoʻonui ʻia ke koi no ke kiʻekiʻe 12Cr1MoVG alloy pipe lōʻihi ma Kina e 10-12% i kēlā me kēia makahiki i ka wā e hiki mai ana. Hoʻokaʻawale ʻia o ka paipu huila 12Cr1MoVG.
ʻO ka pōmaikaʻi nui loa o 12Cr1MoVG alloy pipe hiki ke hana hou ʻia 100%, e like me ka hoʻolālā aupuni o ka mālama ʻana i ke kaiapuni, ka mālama ʻana i ka ikehu a me ka mālama waiwai. Paipai ke kulekele aupuni i ka hoʻonui ʻana i ke kahua noi o ka paipu alloy 12Cr1MoVG kiʻekiʻe.
Ma muli o nā kaʻina hana like ʻole, ua māhele ʻia i loko o ka paipu kila ʻole i ʻōwili ʻia (extruded) a me ka paipu kila ʻole i huki ʻia (rolled). Hoʻokaʻawale ʻia ka paipu i huki ʻia (rolled) i ka paipu pōʻai a me ka paipu ʻano kūikawā.
a. Hōʻike holo kaʻina hana
ʻO ka paipu kila maʻemaʻe i ʻōwili ʻia (hoʻokuʻu ʻia): ʻo ka pahu pōʻai pōʻai → hoʻomehana → perforation → ʻekolu ʻōwili keʻa o ka ʻōwili, ʻōwili mau a extrusion paha → ka wehe ʻana o ka paipu → ka hoʻoemi ʻana (a i ʻole ka hoʻohaʻahaʻa ʻana) → ka hoʻoluʻu ʻana → ka paipu blank → hoʻopololei → hoʻāʻo hydrostatic (a i ʻole ka ʻike kīnā) → hōʻailona → hale kūʻai.
ʻO ka paipu kila ʻole i huki ʻia i ke anu (olokaʻi ʻia): ʻo ka paipu pōʻai pōʻai → hoʻomehana → perforation → poʻomanaʻo → annealing → pickling → ka ʻaila ʻaila (pale keleawe) → kaha kiʻi anu (cold rolling) → blank tube → wela → straightening → hydrostatic test (flaw ʻike) → hōʻailona → hale kūʻai.
