Chitoliro chachitsulo chosasunthika chimapangidwa popanda kuwotcherera ndi njira zotentha zogwirira ntchito monga kugudubuza kotentha kwa perforated. Ngati ndi kotheka, chitoliro chotenthetsera chikhoza kuzizira kwambiri mpaka mawonekedwe omwe mukufuna, kukula ndi magwiridwe antchito. Pakalipano, chitoliro chachitsulo chosasunthika ndiye chitoliro chomwe chimagwiritsidwa ntchito kwambiri pamagawo opanga petrochemical.

Kuyang'anira: kusanthula kwamapangidwe amankhwala, kuyesa kwamakanika, kuyesa kwa flattening ndi kuyesa kuthamanga kwamadzi kuyenera kuchitidwa papaipi yachitsulo yomwe imagwiritsidwa ntchito pamayendedwe ambiri amadzimadzi.

GB5310, GB6479, GB9948mitundu itatu ya muyezo zitsulo chitoliro, kuwonjezera pa chubu zoyendera madzimadzi ayenera kuyesedwa, komanso chofunika kuchita flaring mayeso ndi zotsatira mayeso; Zofunikira pakuwunika kwamitundu itatu iyi yamapaipi achitsulo ndizovuta kwambiri.

GB6479muyezo umapanganso zofunikira zapadera pa kutentha kochepa komwe kumakhudza kulimba kwa zinthu.

GB3087 muyezo zitsulo chitoliro, kuwonjezera pa zonse zofunika mayeso zoyendera madzimadzi zitsulo chitoliro, komanso amafuna ozizira kupinda mayeso.

GB/T8163 muyezo zitsulo chitoliro, kuwonjezera pa mayeso ambiri amafuna kuti madzimadzi zoyendera zitsulo chitoliro, malinga ndi zofunika za pangano kuchita flaring mayeso ndi ozizira kupinda test.The zofunika kupanga mitundu iwiri ya mipope si monga okhwima. monga aja a mitundu itatu yoyambirira.

Kupanga: GB/T/8163 ndi GB3087 muyezo zitsulo chitoliro kutengera ng'anjo lotseguka kapena Converter smelting, zosafunika zake ndi zilema mkati ndi zambiri.

GB9948ng'anjo yamagetsi yosungunula. Ambiri amawonjezedwa ku ng'anjo yoyenga ndi zosakaniza zochepa komanso zolakwika zamkati.

GB6479ndiGB5310miyezo okha amanena zofunika kuyenga kunja kwa ng'anjo, ndi zosafunika osachepera ndi zilema mkati ndi apamwamba zinthu khalidwe.

Miyezo ingapo yapaipi yachitsulo yomwe ili pamwambayi imapangidwa mwadongosolo kuchokera kutsika kupita kumtunda:

GB/T8163＜GB3087＜GB9948＜GB5310＜GB6479

Kusankha: nthawi zonse, GB/T8163 muyezo zitsulo chitoliro ndi oyenera kutentha kapangidwe ndi zosakwana 350 ℃, kuthamanga ndi zosakwana 10.0mpa mankhwala mafuta, mafuta ndi gasi ndi zinthu sing'anga anthu;

Pazinthu zamafuta, mafuta ndi gasi sing'anga, pamene kutentha kwapangidwe kuli kopitilira 350 ℃ kapena kupanikizika kuli kokulirapo kuposa 10.0mpa, ndikofunikira kusankha.GB9948 or GB6479muyezo zitsulo chitoliro;

GB9948 or GB6479muyezo uyenera kugwiritsidwanso ntchito pamapaipi oyendetsedwa pafupi ndi haidrojeni kapena m'malo omwe amatha kuwononga dzimbiri.

General kutentha otsika (zosakwana -20 ℃) ​​ntchito mpweya zitsulo chitoliro ayenera kugwiritsidwa ntchitoGB6479muyezo, kokha umatchula zofunika za otsika kutentha zimakhudza kuuma kwa zipangizo.

GB3087 ndiGB5310Miyezo imayikidwa mwapadera pamiyezo ya chitoliro chachitsulo chowotcha. "Malamulo oyang'anira chitetezo cha boiler" adatsindika kuti zonse zomwe zimalumikizidwa ndi machubu otenthetsera ndizoyang'aniridwa, kugwiritsa ntchito zinthuzo ndi muyezo kuyenera kutsatira malamulo achitetezo cha boiler, chifukwa chake, boiler, malo opangira magetsi, kutentha ndi kupanga petrochemical. chipangizo ntchito pagulu nthunzi chitoliro ayenera kugwiritsidwa ntchito (ndi dongosolo supply) GB3087 kapena muyezoGB5310.

Ndikoyenera kudziwa kuti khalidwe la miyezo yabwino yazitsulo zachitsulo, mitengo yachitsulo yachitsulo ndi yokwera kwambiri, mongaGB9948kuposa mtengo wamtengo wapatali wa GB8163 uli pafupifupi 1/5, kotero, posankha mfundo zazitsulo zachitsulo, ziyenera kuganiziridwa molingana ndi zomwe zimagwiritsidwa ntchito, zonse zodalirika komanso zachuma. Tiyeneranso kukumbukira kuti machubu achitsulo molingana ndi GB/T20801 ndi TSGD0001, GB3087 ndi GB8163 sizigwiritsidwa ntchito mu GC1 mapaipi (pokhapokha ngati akupanga, mtundu wosachepera L2.5, ungagwiritsidwe ntchito pakupanga mapaipi a GC1(1) Kuthamanga kosaposa 4.0Mpa).

(2) Chitoliro chochepa cha aloyi chachitsulo chosasunthika

M'malo opangira petrochemical, miyeso yachitsulo yosasunthika yomwe imagwiritsidwa ntchito nthawi zambiri ya chitsulo cha chromium-molybdenum ndi chromium-molybdenum vanadium chitsulo ndi.

GB9948 "Chitoliro chosasunthika chachitsulo chamafuta amafuta“

GB6479 "Kuthamanga kwambiri kwachitsulo chosasinthika chitoliro cha zipangizo za feteleza“

GB/T5310 "Machubu achitsulo opanda msoko a ma boilers othamanga kwambiri“

GB9948ili ndi zitsulo za chromium molybdenum: 12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo ndi zina zotero.

GB6479ili ndi kalasi yachitsulo ya chromium molybdenum: 12CrMo, 15CrMo, 1Cr5Mo ndi zina zotero.

GB/T5310ili ndi zitsulo za chromium-molybdenum ndi chromium-molybdenum vanadium zitsulo zakuthupi: 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, etc.

Mwa iwo,GB9948amagwiritsidwa ntchito kwambiri.
