Chitoliro chachitsulo chopanda msoko chimapangidwa popanda kusungunula pogwiritsa ntchito njira zogwirira ntchito zotentha monga kupondaponda kotentha koboola. Ngati pakufunika, chitoliro chogwiritsidwa ntchito chotentha chikhoza kuwonjezeredwa kuzizira molingana ndi mawonekedwe, kukula, ndi magwiridwe antchito omwe mukufuna. Pakadali pano, chitoliro chachitsulo chopanda msoko ndicho chitoliro chomwe chimagwiritsidwa ntchito kwambiri mu mayunitsi opanga petrochemical.

(1)Chitoliro cha chitsulo chosapanga dzimbiri cha kaboni 

Kalasi ya zinthu: 10, 20, 09MnV, 16Mn mitundu yonse 4

Muyezo: GB8163 “Chitoliro chachitsulo chosasunthika chonyamulira madzi”

GB/T9711 “Mikhalidwe yaukadaulo yoperekera mapaipi achitsulo m'makampani amafuta ndi gasi”

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

GB/T8163:

Kalasi ya zinthu: 10, 20,Q345, ndi zina zotero.

Kukula kwa ntchito: kutentha komwe kwapangidwa ndi kochepera 350℃, kuthamanga kwa mpweya ndi kochepera 10MPa mafuta, mafuta ndi malo ogwiritsira ntchito anthu onse

GB6479:

Kalasi yazinthu: 10, 20G, 16Mn, ndi zina zotero.

Kuchuluka kwa ntchito: mafuta ndi gasi okhala ndi kutentha kwa kapangidwe kake kwa -40 ~ 400℃ ndi kuthamanga kwa kapangidwe kake kwa 10.0 ~ 32.0MPa

GB9948:

Kalasi ya zinthu: 10, 20, ndi zina zotero.

Kuchuluka kwa ntchito: sikoyenera nthawi ya GB/T8163 ya chitoliro chachitsulo.

GB3087:

Kalasi ya zinthu: 10, 20, ndi zina zotero.

Kukula kwa ntchito: boiler yothamanga kwambiri komanso yapakatikati, nthunzi yotentha kwambiri, madzi otentha, ndi zina zotero.

GB5310:

Kalasi ya zinthu: 20g, etc.

Kukula kwa ntchito: chotenthetsera cha nthunzi chotentha kwambiri cha boiler yothamanga kwambiri

Kuyang'anira: Kusanthula kapangidwe ka mankhwala, mayeso a mphamvu, mayeso ophwanyika ndi mayeso a kuthamanga kwa madzi kuyenera kuchitika pa chitoliro chachitsulo chomwe chimagwiritsidwa ntchito ponyamula madzi ambiri.

GB5310, GB6479, GB9948Mitundu itatu ya chitoliro chachitsulo chokhazikika, kuwonjezera pa chubu choyendera madzimadzi, iyeneranso kuyesedwa, komanso kuyesedwa koyatsa moto ndi mayeso okhudzika; Zofunikira pakuwunika kupanga kwa mitundu itatu iyi ya mapaipi achitsulo ndizovuta kwambiri.

GB6479muyezo umaperekanso zofunikira zapadera kuti zinthu zikhale zolimba kwambiri kutentha.

Chitoliro chachitsulo chokhazikika cha GB3087, kuwonjezera pa zofunikira zonse zoyesera za chitoliro chachitsulo choyendera madzi, komanso chimafuna mayeso ozizira opindika.

Chitoliro chachitsulo chokhazikika cha GB/T8163, kuwonjezera pa zofunikira zonse zoyesera za chitoliro chachitsulo chonyamula madzi, malinga ndi zofunikira za mgwirizano kuti tichite mayeso oyaka moto ndi mayeso opinda ozizira. Zofunikira zopangira mitundu iwiriyi ya mapaipi sizokhwima ngati za mitundu itatu yoyamba.

Kupanga: Chitoliro chachitsulo cha GB/T/8163 ndi GB3087 chimagwiritsa ntchito smelting yotseguka ya uvuni kapena chosinthira, zodetsa zake ndi zolakwika zake zamkati ndizochulukirapo.

GB9948kusungunula ng'anjo yamagetsi. Zambiri zimawonjezeredwa ku njira yoyeretsera ng'anjo ndi zosakaniza zochepa komanso zolakwika zamkati.

GB6479ndiGB5310miyezo yokha imafotokoza zofunikira pakuyeretsa kunja kwa ng'anjo, ndi zodetsa zochepa ndi zolakwika zamkati komanso mtundu wapamwamba kwambiri wa zinthu.

Miyezo ingapo ya mapaipi achitsulo yomwe ili pamwambapa imapangidwa motsatira dongosolo la khalidwe kuyambira pansi mpaka pamwamba:

GB/T8163＜GB3087＜GB9948＜GB5310＜GB6479

Kusankha: nthawi zonse, chitoliro chachitsulo cha GB/T8163 chimayenera kupangidwa chifukwa kutentha kwa kapangidwe kake ndi kochepera 350℃, kupanikizika ndi kochepera 10.0mpa mafuta, mafuta ndi gasi komanso zinthu zogwiritsidwa ntchito pagulu;

Pa zinthu zamafuta, mafuta ndi mpweya, kutentha kwa kapangidwe kake kuli kopitilira 350℃ kapena kupanikizika kuli kopitilira 10.0mpa, ndikoyenera kusankhaGB9948 or GB6479chitoliro chachitsulo chokhazikika;

GB9948 or GB6479muyezo uyeneranso kugwiritsidwa ntchito pa mapaipi omwe amagwiritsidwa ntchito pafupi ndi haidrojeni kapena m'malo omwe dzimbiri limakhalapo.

Kutentha kochepa (kochepera -20℃) pogwiritsa ntchito chitoliro chachitsulo cha kaboni kuyenera kugwiritsidwa ntchitoGB6479muyezo, koma umatchula zofunikira pa kulimba kwa zinthu kutentha kochepa.

GB3087 ndiGB5310Miyezo yakhazikitsidwa mwapadera pa miyezo ya mapaipi achitsulo a boiler. "Malamulo oyang'anira chitetezo cha boiler" adagogomezera kuti zonse zolumikizidwa ndi machubu a boiler ndi za oyang'anira, kugwiritsa ntchito zipangizo ndi muyezo kuyenera kutsatira malamulo a chitetezo cha boiler, chifukwa chake, boiler, malo opangira magetsi, chipangizo chotenthetsera ndi petrochemical chomwe chimagwiritsidwa ntchito mu chitoliro cha nthunzi cha anthu onse chiyenera kugwiritsidwa ntchito (ndi makina operekera) GB3087 kapena muyezo.GB5310.

Ndikoyenera kudziwa kuti khalidwe la miyezo yabwino ya chitoliro chachitsulo, mitengo ya chitoliro chachitsulo ndi yokwera kwambiri, mongaGB9948Mtengo wa zinthu za GB8163 ndi pafupifupi 1/5, chifukwa chake, posankha miyezo ya zinthu za chitoliro chachitsulo, ziyenera kuganiziridwa malinga ndi momwe zimagwiritsidwira ntchito, zonse zodalirika komanso zachuma. Tiyeneranso kudziwa kuti machubu achitsulo motsatira GB/T20801 ndi TSGD0001, GB3087 ndi GB8163 sayenera kugwiritsidwa ntchito mu chitoliro cha GC1 (pokhapokha ngati ultrasonic iliyonse, khalidwe losachepera L2.5, lingagwiritsidwe ntchito mu chitoliro cha GC1(1) chomwe sichiposa 4.0Mpa).

(2) Chitoliro chachitsulo chopanda msoko chachitsulo chopanda aloyi

Mu malo opangira mafuta, miyezo ya mapaipi achitsulo chosapanga dzimbiri yogwiritsidwa ntchito kwambiri ya chitsulo cha chromium-molybdenum ndi chitsulo cha chromium-molybdenum vanadium ndi
