Wopanga:Gulu la zitsulo
Mtundu Wogulitsa:Chitoliro chachitsulo chosawoneka
Gawo lazinthu:ASTM A106 GRA B
Ntchito:Kutentha kwambiri komanso kayendedwe kake, petrochemical, m'badwo wamphamvu, mafakitale
Kupanga Kopanga:Womalizidwa kapena wozizira wopanda pake wopanda pake
Muyezo:Astm A106 / ASME sa106
Kulemeletsa
A106 GRA B NACA chitoliro chimapangidwa kuti ligwiritse ntchito wowawasa, pomwe kuwonekera kwa hydrogen sulfide (h₂s) kapena zinthu zina zongono. Zingwe zachitsulo zimapanga ma pace mapaipi omwe amapangidwa kuti apereke kukana kwapadera kuti athetse kupsinjika (SSC) ndi Hydrogen-issogle-madera oyambitsidwa ndi kutentha kwambiri. Mapaipi awa amakumana ndi Miyezo ya Mr 0175, ndikuwonetsetsa kuti ali oyenerera kuti azigwiritsa ntchito mafuta ngati mafuta & mpweya, kukonzanso mankhwala, ndi m'badwo wamphamvu.
Kuphatikizika kwa mankhwala
Kuphatikizika kwa mankhwala a A106 G Nace chitoliro chimakonzedwa kuti chikhale cholimba komanso kukana, makamaka m'malo owawasa atumiki.
| Elementi | Min% | Max% |
| Kaboni (c) | 0.26 | 0.32 |
| Manganese (Mn) | 0,60 | 0.90 |
| Silicon (SI) | 0.10 | 0.35 |
| Phosphorous (p) | - | 0.035 |
| Sulfure (s) | - | 0.035 |
| Copper (CU) | - | 0.40 |
| Nickel (ni) | - | 0.25 |
| Chromium (CR) | - | 0.30 |
| Molybdenum (mo) | - | 0.12 |
Ndondomeko iyi idapangidwa kuti ipereke mphamvu powonetsetsa chitolirocho chimatha kupirira malo obiriwira a acidic.
Makina
A106 GRA B NACA Chipikika chimapangidwa kuti lizichita zinthu zambiri mopambanitsa, ndikupangitsa kuti mphamvu zonsezi zikhale zovuta komanso kutentha.
| Nyumba | Peza mtengo |
| Gwiritsani mphamvu (σ₀.₂) | 205 mpa |
| Mphamvu yayikulu (σb) | 415-550 MPA |
| Elongition (el) | ≥ 20% |
| Kuuma | ≤ 85 hrb |
| Zimakhudza kulimba mtima | ≥ 20 J pa -20 ° C |
Mphamvuzi zimatsimikizira kuti chitoliro cha nativala chimatha kupewa kusokonekera komanso kupsinjika pamachitidwe ovuta monga kupanikizika kwambiri, kutentha kwambiri, komanso madera owawasa.
Kukana kwa Corrosion (HIC & SSS)
A106 GRA B NACA Chipika chimapangidwa kuti lizikambasuliratu zinthu zowunjikiza, ndipo zimayesedwa mwamphamvu za hydrogen zomwe zimapangidwira kusokonekera (HIC) ndi Kupsinjika kwa SC175. Kuyesaku ndikofunikira pakuwunika chitoliro cha chitoliro chogwiritsa ntchito malo omwe hydrogen sulfide kapena mankhwala ena acid alipo.
HIC (Hydrogen itayikidwa kusokonekera) kuyesedwa
Kuyesedwa uku kumawunikira kukana kwa chitoliro cha hydrogen-yotsekemera komwe kumachitika chifukwa cha malo owawasa, monga omwe ali ndi hydrogen sulfide (h₂s).
SSC (kupsinjika kopsinjika) kuyesera
Kuyesaku kumayesa kuthekera kwa chipika kuti mupewe kusokonekera mukakumana ndi hydrogen sulfide. Imayang'anira zochitika zowawa za malo owawa ngati mafuta ndi minda yamafuta.
Mayeso onsewa akuwonetsetsa kuti A106 G NAM B NAace Puip imakumana ndi zofuna za mafakitale omwe amagwira ntchito m'matumbo okalamba, ndipo chitsulo sichingalepheretse kusweka ndi mitundu ina ya kutukuka.
Katundu wathupi
A106 GRA B NAace pipa ili ndi zinthu zotsatirazi zomwe zikuwonetsetsa kuti zimachitika modalirika pang'ono ndi kupsinjika:
| Nyumba | Peza mtengo |
| Kukula | 7.85 g / cm³ |
| Mafuta Omwe Amachita | 45.5 W / mu · K |
| Elastic modulus | 200 GPA |
| Kuchulukitsa kwa matenthedwe | 11.5 x 10⁻⁶ / ° C |
| Kusamala kwamagetsi | 0.00000103 ω ω ω m |
Izi zimaloleza chitoliro kuti chitoliro chikhalebe ndi umphumphu ngakhale mosiyanasiyana komanso kusinthasintha.
Kuyendera ndi Kuyesa
Zingwe zachitsulo zimagwiritsa ntchito njira zowunikira kuonetsetsa kuti A106 GRA B NAC B NAce Piva imakumana ndi miyezo yapadziko lonse lapansi. Mayeso awa akuphatikiza:
● Kuyendera kowoneka bwino:Kuwonetsetsa machiponi omwe amagwirizana ndi makampani.
● Kuyesa kwamatsenga:Ankakonda kuyang'ana luso la chitoliro kuti athe kupirira kupsinjika kwakukulu.
● Kuyesa kowononga (NDT):Njira monga ma akuyeso akupanga (UT) ndi Eddy Pakali pano (Eddy) amagwiritsidwa ntchito kuzindikira zolakwika zamkati popanda kuwononga chitoliro.
● Tudile, zoyeserera, komanso kuyezetsa kwamphamvu:Kuwunika makina omwe ali ndi zovuta zosiyanasiyana.
●Kuyesa Kwa Acid Acid:Kuphatikiza mayeso a HIC ndi SSS, monga mr 0175, kutsimikizira magwiridwe antchito owawasa.
Katswiri Wopanga Wachitsulo
Maluso opanga zitsulo zopanga zamatsenga zimamangidwa mozungulira malo osenda osenda ndikudzipereka kwambiri kuwongolera bwino. Ndili ndi zaka 19 zokumana nazo zamakampani, zitsulo zachikazi zimapangitsa kuti pakhale mapaipi apamwamba kwambiri omwe amakwaniritsa zofuna za ntchito zokopa kwambiri.
●Tekinolo Yabwino Yopanga:Zingwe zitsulo zimagwira ntchito zopangidwa ndi zojambulajambula zomwe zimaphatikizira zomwe zimaphatikizana kwambiri zomwe zimaphatikizira chipika chosawoneka, kutentha kwa kutentha, komanso njira zapamwamba zokutira.
●Kusinthana:Kupereka njira zothetsera mavuto, kuphatikizapo ma stades osiyanasiyana, zokutira, ndi chithandizo chamagetsi, zitsulo zachitsulo zojambula za kasitomala.
●Kutumiza Zinthu Padziko Lonse:Ndi luso lotumiza kunja kwa mayiko opitilira 100, zitsulo zozizwitsa zimatsimikizira zodalirika komanso panthawi yake zosonyeza mapaipi apamwamba padziko lonse lapansi.
Mapeto
A106 GRA B NACA chitoliro chochokera chachitsulo chazichilic chimaphatikiza zinthu zamakina, kukana kwa makina, komanso kudalirika mu ntchito youkira. Ndi yabwino kutentha kwambiri, kugwiritsa ntchito kwambiri mafakitale monga mafuta & mpweya, petrochemical, ndi mankhwala. Miyezo yoyeserera yokha, kuphatikizapo kuiyeza kwa HIC ndi SSS pa Mr 0175, onetsetsani kuti chitoliro cha chitoliro ndi kukana kuwonongeka m'maziko ovuta.
Kuthekera kwamisala yapakatikati, kudzipereka kwa mtundu, komanso zomwe zidapangitsa kunja
Sankhani gulu lachiberekero ngati bwenzi lanu lodalirika la mapaipi apamwamba osapanga dzimbiri ndi magwiridwe antchito komanso magwiridwe antchito osavomerezeka. Kuvomerezedwa!
