Le pipe yentsimbi engenamthungo isetyenziswa kakhulu ekwenziweni kweepayipi zebhoyila kunye nezitshintshi zobushushu, inika isiqinisekiso esiqinileyo semveliso yemizi-mveliso.

Amanqaku aphambili

GB/T5310imibhobho yentsimbi esemgangathweni engenamthungo yenziwe ikakhulu nge-Cr-Mo alloy kunye ne-Mn alloy, kwaye iiklasi eziphambili ziquka20G, 20Mg, 20MoG, 12CrMoG, njl. Ezi zinto zinamandla aphezulu obushushu kunye nokumelana ne-oxidation, kwaye zingasetyenziswa ixesha elide kwiindawo zokusebenza ezinzima ngaphandle kokusilela. Phakathi kwazo:

20G: Intsimbi yesakhiwo sekhabhoni esemgangathweni ophezulu eneplastiki elungileyo kunye nokuqina, esetyenziswa rhoqo kwimibhobho yebhoyila enoxinzelelo oluphakathi noluphantsi.
20Mg: Ukongeza i-manganese kwi-20G kuphucula ngakumbi amandla kunye nobunzima bezinto, ezifanelekileyo kwiipayipi zebhoyila ezinoxinzelelo oluphakathi noluphezulu.
I-20MoG: I-Molybdenum yongezwa kwi-20G, nto leyo ephucula kakhulu ukumelana nobushushu kunye nokuqhekeka, kwaye ifanelekile kwiipayipi zebhoyila ezinoxinzelelo oluphezulu.
12CrMoG: Intsimbi yesakhiwo se-alloy equlethe i-chromium kunye ne-molybdenum, enokumelana okuhle kakhulu ne-oxidation kubushushu obuphezulu kunye namandla obushushu obuphezulu, ifanelekile kwiipayipi zebhoyila ezinoxinzelelo oluphezulu kakhulu.
Amanqanaba esinyithi esakhiweyo se-alloy

Iindidi zentsimbi ezakhiwe nge-alloy zeepayipi zentsimbi ezingenamthungo ze-GB/T5310 nazo ziquka i-15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, njl. Ezi ndidi zepayipi zentsimbi zineempawu ezahlukeneyo zoomatshini kunye noluhlu olufanelekileyo ngokweekhemikhali ezahlukeneyo kunye neenkqubo zonyango lobushushu:

I-15MoG kunye ne-20MoG: Ukongezwa kwesixa esifanelekileyo se-molybdenum kuphucula kakhulu amandla obushushu obuphezulu kunye nokumelana nokugqwala kombhobho wentsimbi.
12CrMoG kunye15CrMoG: Ukongezwa kwe-chromium kunye ne-molybdenum kwandisa ukumelana ne-oxidation kunye namandla obushushu aphezulu embhobho wentsimbi, kwaye kufanelekile kwiindawo ezinamaqondo obushushu aphezulu kunye noxinzelelo.
I-12Cr2MoG kunye ne-12CrMoVG: Ulwakhiwo lwe-alloy luphuculwa ngakumbi, lunamandla obushushu aphezulu kunye nokumelana ne-oxidation, kwaye lusebenza kakuhle kakhulu kwiindawo ezixineneyo.
Izicelo
Iipayipi zentsimbi ezingenamthungo eziqhelekileyo ze-GB/T5310 zisetyenziswa kakhulu kwiipayipi zebhoyila nakwii-heat exchangers, ikakhulu kwizixhobo zobushushu obuphezulu kunye noxinzelelo oluphezulu ezifana neebhoyila zesikhululo samandla, iibhoyila zemizi-mveliso, kunye neebhoyila zobushushu obungcolileyo. Ezi pipes zentsimbi ezingenamthungo zinokumelana noxinzelelo oluphezulu kakhulu lokusebenza kunye namaqondo obushushu, ukuqinisekisa ukusebenza kakuhle kunye nobomi obude beebhoyila kunye nee-heat exchangers. Ukongeza, ezi pipes zentsimbi zikwasetyenziswa kwizixhobo zokutshintsha ubushushu kwishishini le-petrochemical, nto leyo eyandisa ngakumbi iindawo zazo zokusebenza.
Isishwankathelo
Iipayipi zentsimbi ezingenamthungo ze-GB/T5310 ezisemgangathweni ziye zaba yimveliso ekhethwayo kwiipayipi zebhoyila ezinoxinzelelo oluphezulu nangaphezulu ngenxa yeempawu zazo ezintle zezinto kunye noluhlu olubanzi lwezicelo. Nokuba yi-20G, 20Mg, 20MoG, 12CrMoG kunye nezinye izinto, okanye i-15MoG, 20MoG, 12CrMoG kunye nezinye iintlobo zentsimbi ezakhiweyo, zonke zibonisa ukumelana okugqwesileyo kwe-oxidation kubushushu obuphezulu kunye namandla obushushu aphezulu, zibonelela ngeziqinisekiso ezinokuthenjwa zokusebenza ngokukhuselekileyo nangokufanelekileyo kwezixhobo zoshishino.
