ASTM A335 P5ʻO ka paipu wela kiʻekiʻe Ferritic Seamless kila kila o ke kūlana ʻAmelika. ʻO ka paipu Alloy kahi ʻano o ka paipu kila humuhumu, ʻoi aku ka kiʻekiʻe o kāna hana ma mua o ka paipu kila humuhumu maʻamau, no ka mea, ʻoi aku ka nui o ka C i loko o kēia ʻano paipu kila, ʻoi aku ka liʻiliʻi o ka hana ma mua o ka paipu kila humuhumu maʻamau, no laila ua hoʻohana nui ʻia ka paipu Alloy i ka petroleum, Aerospace, Chemical, Electric Power, Boiler, Military a me nā ʻoihana ʻē aʻe.

ʻO ka paipu kila kila he nui nā mea ʻē aʻe ma mua o ke kalapona e like me Nickel, Chromium, Silicon, Manganese, Tungsten, Molybdenum, Vanadium a me nā palena palena o nā mea ʻē aʻe i ʻae ʻia e like me Manganese, Sulfur, Silicon, a me Phosphorus.

Ke kila kila kūloko e pili ana: 1Cr5MoGB 9948-2006"Paipu kila humuhumu maʻamau no ka haki ʻana o ka ʻaila"

• Uku: 30% Waihona, 70% L/C A i ʻole B/L Kope A i ʻole 100% L/C Ma ka ʻIke
• Ka nui o ke kauoha liʻiliʻi loa: 1 PC
• Ka Mana Hoʻolako: Ka Waihona Makahiki 20000 Tons o ka Paipu Kila

• Ka Manawa Alakaʻi: 7-14 mau lā inā ma ka waihona, 30-45 mau lā e hana ai
• Hoʻopili ʻia: Nalowale ʻeleʻele, Bevel a me ka pāpale no kēlā me kēia paipu hoʻokahi; Pono e hoʻopili ʻia ʻo OD ma lalo o 219mm i loko o ka pūʻolo, a ʻaʻole e ʻoi aku kēlā me kēia pūʻolo ma mua o 2 tons.

Kaʻina hana: Hoʻāʻo paʻakikī:

1. ʻŌwili wela (paipu kila wili ʻole i hoʻokuʻu ʻia): ʻōwili paipu poepoe → hoʻomehana → perforation → ʻōwili keʻa ʻekolu-ʻōwili, ʻōwili mau a i ʻole extrusion → wehe ʻana i ka paipu → ka nui (a i ʻole ka hōʻemi ʻana) → hoʻoluʻu → hoʻopololei → hoʻāʻo kaomi wai (a i ʻole ka ʻike ʻana i nā hemahema) → māka → mālama

2. Kahaki anu (ʻōwili) paipu kila humuhumu: paipu poepoe billet → hoʻomehana → perforation → poʻomanaʻo → annealing → pickling → aila (plating keleawe) → kahaki anu multi-pass (ʻōwili anu) → paipu hakahaka → mālama wela → hoʻopololei → hoʻāʻo kaomi wai (ʻike kīnā) → māka → mālama

Hoʻopili ʻana:

ʻO ka hoʻopili ʻōlohelohe/hoʻopili pūʻolo/hoʻopili pahu/pale lāʻau ma nā ʻaoʻao ʻelua o nā paipu a pale pono ʻia no ka lawe ʻana i ke kai a i ʻole e like me ke noi.
