NA PAPA MAHELE HAAHAA
Nui Pipe--1/4” Nominal a 42”OD
Mānoanoa Pā – Hōʻike 10 a hiki i ka XXH
Ua kūkulu ʻia nā kila kalapona haʻahaʻa haʻahaʻa no ka hoʻohana ʻana i nā mea haʻahaʻa haʻahaʻa a ʻoi aku hoʻi no nā moku kaomi welded.
He haʻahaʻa a hiki i ka medium-carbon (0.20 a 0.30%), kiʻekiʻe-manganese (0.70 a 1.60%), silika (0.15 a 0.60%) mau kila, nona kahi ʻano palaoa maikaʻi me ka hoʻopuehu carbide like.Hōʻike lākou i ka ikaika haʻahaʻa me ka paʻakikī a hiki i - 50°F (-46°C).
No ka hoʻomaʻemaʻe palaoa a me ka hoʻomaikaʻi ʻana i ke ʻano a me ka weldability, hiki i nā kila kalapona ke loaʻa i ka 0.01 a 0.04% columbium.Kapa ʻia nā kila columbium, hoʻohana ʻia lākou no nā shafts, forgings, gears, machine parts, and dies and gages.A hiki i ka 0.15% sulfur, a i ʻole 0.045 phosphorus, hoʻolilo iā lākou i ka mīkini manuahi, akā hoʻemi i ka ikaika.
ʻO LTCS he Nickel ma muli o nā pā kila kila i hoʻohana nui ʻia no nā noi haʻahaʻa haʻahaʻa ma lalo - 150 deg F. Hoʻohana nui ʻia i ka hana cryogenic o nā moku ākea, noi haʻahaʻa wela i ka mea kanu kemika ma lalo o -55 deg C.

Haʻahaʻa wela kalapona kila paipu quenching wela ma A3 + (30 ~ 50) ℃, ma ka hana, ua hoonoho mau i ka luna palena.High quenching wela wela paipu hiki ke hana haʻahaʻa wikiwiki, ili oxidation hoemi, a hiki ke hoʻoikaika i ka hana pono.He austenite like ʻole ka mea hana, pono ka manawa paʻa.Inā ʻo ka mana o ka umu ahi i hoʻokomo ʻia, pono e hoʻonui i ka manawa paʻa.A i ʻole, ʻaʻole lawa ka paʻakikī ma muli o ka hoʻomehana ʻole ʻia e ka hanana.Eia nō naʻe, lōʻihi loa ka manawa paʻa, e ʻike pū ʻia nā ʻano kīʻaha koʻikoʻi, oxidation a me ka decarbonization i nā maʻi koʻikoʻi e pili ana i ka maikaʻi quenching.Manaʻo mākou inā ʻoi aku ka nui o ka umu i hoʻokomo ʻia ma mua o nā palapala kaʻina hana, e hoʻonui ʻia ka manawa paʻa wela i ka 1/5.
Haʻahaʻa wela kalapona kila paipu ma muli o ka haʻahaʻa hardenability, pono ia e lawe i ka nui hooluolu ana o ka 10% paakai.Mea hana i loko o ka wai, pono hardenability, akā,ʻaʻole chilled, ina 45 # precision kila chilled i loko o ka brine, e hiki mawae o ka workpiece, keia no ka mea, i ka wa e hooluolu ai ka workpiece a hiki i 180 ℃, ka austenite hoohuli koke i ka lio s kino. ʻiʻo ma muli o ke kaumaha nui.No laila, i ka wā e hoʻomaloʻo koke ai ke kila hoʻoheheʻe a me ka hoʻoheheʻe ʻana i kēia pae wela, pono e lawe ʻia ke ala e hoʻolōʻihi i ka hoʻoilo.
Ma muli o ka paʻakikī o ka ʻike ʻana i ka mahana o ka wai, ka ʻike kūpono i ka hana ʻana, ke pau ka wai i ka hoʻoheheʻe ʻana i nā mea waiwai, hiki iā ʻoe ke hoʻomaʻalili i ka wai (e laʻa, ʻoi aku ka maikaʻi o ka ʻaila ʻaila).Eia hou, i ka workpiece i loko o ka wai, pono hana e mau e like me ka geometry o ka workpiece, e like me ka hana mau.ʻO ka mea hoʻoluʻu paʻa paʻa me ka mea hana paʻa, ka hopena i ka paʻakikī paʻa ʻole, ke koʻikoʻi ʻole ka waiho ʻana i ka deformation nui o ka mea hana, a me ka māhā.
