Ma Iulai 8, 2023, ua hoʻouna mākou i ka ASTM A335 P92 seamless alloy pipes i Italia, a hāʻawi iā lākou i ka manawa. I kēia manawa, ua hana mākou i 100% hoʻopaʻa paʻa, e komo pū ana i ka pahu PVC, ka ʻeke ʻeke i ulana ʻia, a me ka ʻeke pepa i piha i ka sponge, hiki ke hoʻohana hou ʻia e like me nā kaula hao holoʻokoʻa e hoʻohana ʻia e hoʻopili i nā paipu, a ua hoʻopiha ʻia nā paipu e pili ana iā lākou. anti-collision bubble pepa a me ka sponge filling paper, a hoʻopili hope ʻia i loko o nā pahu lāʻau. Ma waho o ka pahu lāʻau, hoʻohana mākou i kahi kāʻei kila ikaika loa e hoʻoponopono i ka pahu, i mea e pale ai i loko a me waho o ka paipu holoʻokoʻa.
ʻO ka hāʻawi ʻana i nā huahana mai nā mea kūʻai aku Italia ua kau i kahi kumu ʻoi aku ka maikaʻi no kā mākou mākeke ʻEulopa, a ke kakali nei mākou i kā mākou hui hou ʻana!
ʻO ka ASTM A335 P92 he paipu kila kila ʻole, ka mea i hoʻohana nui ʻia i nā mea kanu wela i nā makahiki i hala iho nei, ka mea nui no nā paipu mahu a me nā paipu mahu.
A335 P92 haku mele mele: 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≤0.50~ N: ≤0.02 Ti: ≤0.01 Zr≤0.01Nb: 0.04~0.09 W: 1.5~2.0 B: 0.001~0.006
ʻO ka ASTM A335 P92 ka mea hoʻoheheʻe ʻole ʻia o ka paipu kila kila: ikaika tensile ≥ 620Map, ikaika hua ≥ 440Mpa, elongation ma hope o ka haki ʻana ≥ 20%
ASEM SA335 P92 Seamless Alloy Steel Pipe Ke kūlana hoʻouna: Normalizing + Tempering
ʻO ASEM A335 P92 ka nui o ka paipu kila kila: 60.3-765*2-120, nā anawaena maʻamau 60.3, 73, 88.9, 114.3, 168.3, 219.1, 273.1, 323.9, 405.6, 60.5 0, 660 , 711, 762, a me nā nui ʻē aʻe hiki ke hoʻopilikino ʻia e like me nā koi o ka mea kūʻai aku.
ʻO ka noi nui o ASME SA335 P92 alloy steel pipe: hoʻohana nui ʻia i ka hana ʻana i nā superheaters a me nā reheater no nā pūʻulu generator nui.
ʻO ka maʻamau ʻAmelika ʻo ASTMA335 alloy pipe e pili ana i ka pae kila P11, P12, P5, P9, P91 mea.
ʻO A335 P11 kahi code waiwai i hoʻopuka ʻia e ka ASTM (American Society for Testing and Materials), a ʻo ka maʻamau ʻāina e pili ana ʻo 15CrMo, kahi mea hao hao.
ʻO ASTM A335 P5 e pili ana i ke kila kila kūloko: 1Cr5Mo. ʻO ke ʻano metala o 1Cr5Mo he martensite, nona ke kūpaʻa oxidation maikaʻi ma kahi o 650 degere Celsius, ka ikaika wela maikaʻi ma lalo o 600 degere Celsius, ka haʻalulu maikaʻi a me ka conductivity thermal, a hoʻohana nui ʻia i nā turbines mahu.
ʻO ka maʻamau ʻAmelika astm a335p91 e like me ka maʻamau 10Cr9Mo1VNb. T91/P91 (10Cr9Mo1VNb)
Ka hoʻohui waiwai o P91 (mea hoʻohui wt%):
C 0.08~0.12; Mn 0.30~0.60; Si 0.20~0.50; P ≤0.02; S ≤0.01; Kr 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
ʻAmelika maʻamau maʻamau kila paipu a106 seamless kila paipu mea kekahi huahana me ka nui loa.
No ka paipu kila maʻamau ʻo ʻAmelika ʻAmelika, ʻo A106 me A106-A, A106-B. Ua like ka mua me ka waiwai 10# home, a ua like ka mea hope me ka mea 20# hale.
Ka manawa hoʻouna: Jul-10-2023
