Ma Iulai 8, 2023, ua hoʻouna mākou i nā paipu kila kila ASTM A335 P92 seamless i Italia, a ua hāʻawi iā lākou i ka manawa kūpono. I kēia manawa, ua hana mākou i ka 100% pack i hoʻoikaika ʻia, me ka pack PVC, ka pack ʻeke ulana, a me ka pack pepa i hoʻopiha ʻia me ka huʻahuʻa, hiki ke hoʻohana hou ʻia. Hoʻohana ʻia nā kaula kila e hoʻopaʻa i nā paipu, a ua hoʻopiha ʻia nā paipu ma ko lākou ʻaoʻao me ka pepa pehu anti-collision a me ka pepa hoʻopiha huʻahuʻa, a ua hoʻopaʻa hope ʻia i loko o nā pahu lāʻau. Ma waho o ka pahu lāʻau, hoʻohana pū mākou i kahi kāʻei kila ikaika loa e hoʻopaʻa i ka pahu, i mea e pale ai i loko a ma waho o ka paipu holoʻokoʻa.
ʻO ka lawe ʻana mai o nā huahana mai nā mea kūʻai aku Italia ua hoʻokumu i kahi kahua maikaʻi aʻe no kā mākou mākeke ʻEulopa, a ke kakali nei mākou i kā mākou hana like aʻe!
ʻO ASTM A335 P92 kahi paipu kila kila humuhumu ʻole, ka mea i hoʻohana nui ʻia i nā mea kanu mana wela i nā makahiki i hala iho nei, ʻo ia hoʻi no nā paipu mahu nui a me ka hoʻomehana hou ʻana i nā paipu mahu.
ʻO ka hoʻohuihui kemika A335 P92: C: 0.07~0.13 Si: ≤0.50 Mn: 0.30~0.60 P≤0.020 S≤0.010 Cr: 8.50~9.50 Mo: 0.30~0.60Ni≤0.40 V:0.15~0.25 N:0.03~0.07 Al: ≤0.02 Ti: ≤0.01 Zr≤0.01Nb: 0.04~0.09 W: 1.5~2.0 B: 0.001~0.006
ʻO nā waiwai mechanical o ka paipu kila kila ASTM A335 P92: ikaika tensile ≥ 620Map, ikaika hua ≥ 440Mpa, elongation ma hope o ka haki ≥ 20%
Kūlana Hoʻouna Paipu Kila Alloy ʻO ASEM SA335 P92 Seamless: Normalizing + Tempering
ʻO ka nui o ka paipu kila kila ASEM A335 P92: 60.3-765*2-120, nā anawaena i hoʻohana pinepine ʻia he 60.3, 73, 88.9, 114.3, 168.3, 219.1, 273.1, 323.9, 355.6, 406.4, 457.2, 508, 559, 610, 660, 711, 762, a hiki ke hoʻopilikino ʻia nā nui ʻē aʻe e like me nā koi o ka mea kūʻai aku.
ʻO ka noi nui o ka paipu kila kila ASME SA335 P92: hoʻohana nui ʻia i ka hana ʻana o nā superheaters a me nā reheater no nā set generator nui
ʻO ka paipu huila ASTMA335 maʻamau ʻAmelika e pili ana i ka mea kila P11, P12, P5, P9, P91
ʻO A335 P11 kahi code mea i hoʻopuka ʻia e ASTM (American Society for Testing and Materials), a ʻo ke kūlana aupuni e pili ana he 15CrMo, kahi mea kila alloy.
Pili ʻo ASTM A335 P5 i ke kila hui kūloko: 1Cr5Mo. ʻO ke ʻano metala o 1Cr5Mo he martensite, nona ke kūpaʻa oxidation maikaʻi ma kahi o 650 degere Celsius, ikaika wela maikaʻi ma lalo o 600 degere Celsius, hoʻopili haʻalulu maikaʻi a me ka conductivity thermal, a hoʻohana nui ʻia i nā turbine mahu.
Ua like ke kūlana ʻAmelika astm a335p91 me ke kūlana aupuni 10Cr9Mo1VNb. T91/P91 (10Cr9Mo1VNb)
Ka haku mele ʻana o ka mea o P91 (mea hoʻohui wt%):
ʻO C 0.08~0.12; Mn 0.30~0.60; Si 0.20~0.50; P ≤0.02; S ≤0.01; Cr 8.0~9.5;
Mo 0.85~1.05; V 0.18~0.25; Nb 0.06~0.1; N 0.03~0.07; Al ≤0.04; Ni ≤0.4
ʻO ka paipu kila kila maʻamau ʻAmelika A106 he huahana nui loa ka paipu kila kila.
No ka paipu kila maʻamau ʻAmelika ka paipu kila ASTM A106, aia pū ʻo A106-A a me A106-B i loko. ʻO ka mea mua, ua like ia me ka mea 10 # kūloko, a ʻo ka mea hope, ua like ia me ka mea 20 # kūloko.
Ka manawa hoʻouna: Iulai-10-2023
