ʻO ASTM A335 P9, i ʻike ʻia hoʻi ʻo ASME SA335 P9, he paipu kila ferritic seamless no ka lawelawe wela kiʻekiʻe meUNS No. K90941.
ʻO nā mea hoʻohuihui he chromium a me molybdenum. Loaʻa ka nui o ka chromium mai 8.00 - 10.00%, ʻoiai aia ka nui o ka molybdenum ma ka pae o 0.90% - 1.10%.
P9He ikaika maikaʻi loa a he kūpaʻa maikaʻi i ka pala i nā wahi wela kiʻekiʻe a hoʻohana nui ʻia i nā paila, nā lako petrochemical, a me nā kikowaena mana kahi e pono ai nā wahi wela kiʻekiʻe a me ke kaomi kiʻekiʻe.
⇒ Mea HanaPaipu kila me ka ʻaila huila ASTM A335 P9 / ASME SA335 P9.
⇒Anawaena o waho1/8"- 24".

⇒Ka lōʻihiNā lōʻihi kikoʻī a kaulele paha.
⇒Hoʻopilikino ʻana: Ke anawaena waho maʻamau ʻole, ka mānoanoa o ka paia, ka lōʻihi, a pēlā aku e like me nā koi.
⇒Nā mea hoʻohuiHiki iā mākou ke hāʻawi i nā kūlou mea like, nā flanges stamping, a me nā huahana kākoʻo paipu kila ʻē aʻe.
⇒Palapala hōʻoia IBRHiki ke hāʻawi ʻia kahi palapala hōʻoia IBR inā pono.
⇒PauʻO ka welau maʻamau, ka welau beveled, a i ʻole ka welau paipu i hui pū ʻia.
⇒Hoʻopili ʻana: hihia lāʻau, kāʻei kila a i ʻole ka uea kila e hoʻopili ana, pale hopena paipu plastik a hao paha.
⇒Ka halihali: ma ke kai a i ʻole ka mokulele.
Pono ka paipu kila ASTM A335 e humuhumu ʻole ʻia.
ʻO ka paipu kila humuhumu he paipu kila me ka ʻole o nā wili ma loko.
ʻOiai ʻaʻohe ʻano wili ʻia o ka paipu kila humuhumu ʻole i loko o kona ʻano, pale ia i nā pōpilikia palekana e pili ana i nā pilikia maikaʻi o ka wili ʻana. ʻAe kēia hiʻohiʻona i ka paipu humuhumu ʻole e kū i nā kaomi kiʻekiʻe, a ʻo kona ʻano kūloko like e hōʻoia hou i ka pono a me ka palekana o ka paipu i nā wahi kaomi kiʻekiʻe.
Eia kekahi, ua hoʻonui ʻia ka hilinaʻi o nā paipu ASTM A335 e ka hoʻohui ʻana o nā mea hoʻohuihui kūikawā no nā kūlana wela kiʻekiʻe a me ke kaomi kiʻekiʻe.
ʻO nā ʻano hana wela i loaʻa no ka mea P9 e komo pū me ka annealing piha a isothermal paha, a me ka normalizing a me ka tempering. ʻO ke kaʻina hana normalizing a me ka tempering he mahana tempering o 1250°F [675°C].
ʻO nā mea hoʻohuihui nui o P9Cra meMo, ʻo ia hoʻi nā metala chromium-molybdenum.
Cr (Chromium)Ma ke ʻano he mea nui o ka hui hao, hāʻawi ʻo Cr i ka ikaika wela kiʻekiʻe maikaʻi loa a me ke kūʻē ʻana i ka oxidation. Hoʻokumu ia i kahi ʻili chromium oxide mānoanoa ma luna o ka ʻili o ke kila, e hoʻonui ana i ke kūpaʻa a me ke kūʻē ʻana i ka pala o ka paipu i nā mahana kiʻekiʻe.
Mo (Molybdenum)ʻO ka hoʻohui ʻana o Mo e hoʻomaikaʻi nui i ka ikaika a me ke kūpaʻa o nā mea hao hao, ʻoi aku hoʻi i nā wahi wela kiʻekiʻe. Kōkua pū ʻo Mo i ka hoʻomaikaʻi ʻana i ka ikaika kolo o ka mea, ʻo ia hoʻi ka hiki ke kūʻē i ka deformation ma lalo o ka hoʻolaha wela lōʻihi.
