Intshayelelo yomgangatho ophezulu wekhabhoni yolwakhiwo lwentsimbi kunye nealloyi yolwakhiwo lwentsimbi yemibhobho yentsimbi engenamthungo yoxinzelelo oluphezulu nangaphezulu kwemibhobho yebhoyila yomphunga.
GB/T5310imibhobho yentsimbi esemgangathweni engenamthungo ziimveliso ezikumgangatho ophezulu ezenzelwe uxinzelelo oluphezulu kunye nemibhobho yebhoyila yomphunga.Zenziwe nge-high-quality carbon structural steel kunye ne-alloy structural steel materials ukuze kuqinisekiswe ukusebenza kwazo okugqwesileyo kunye nokuthembeka kwiindawo eziphezulu zokushisa kunye noxinzelelo oluphezulu.Lo mbhobho wensimbi ongenamthungo usetyenziswa ngokubanzi ekwenzeni imibhobho yebhoyila kunye nokutshintshana kobushushu, ukubonelela ngesiqinisekiso esiqinileyo sokuveliswa kwemveliso.
Amabanga aphambili
GB/T5310imibhobho yentsimbi esemgangathweni engenamthungo yenziwa ikakhulu nge-Cr-Mo alloy kunye ne-Mn alloy, kwaye amabakala aphambili abandakanya20G, 20Mg, 20MoG, 12CrMoG, njl. Ezi zixhobo zinamandla aphezulu okushisa kunye nokumelana ne-oxidation, kwaye zingasetyenziselwa ixesha elide kwiindawo zokusebenza ezinzima ngaphandle kokungaphumeleli.Phakathi kwabo:
20G: I-carbon structural steel high quality kunye neplastiki enhle kunye nokuqina, esetyenziswa ngokuqhelekileyo kwimibhobho yebhoyili ephakathi kunye nephantsi.
I-20Mg: Ukongeza i-manganese kwi-20G iphucula ngakumbi amandla kunye nobunzima bezinto eziphathekayo, ezifanelekileyo kwimibhobho yebhoyili ephakathi kunye noxinzelelo oluphezulu.
I-20MoG: I-Molybdenum yongezwa kwi-20G, ephucula kakhulu ukuchasana nokushisa kunye nokuxhatshazwa kwe-creep, kwaye ifanelekile kwimibhobho yebhoyili ephezulu.
12CrMoG: I-alloy structural steel equkethe i-chromium kunye ne-molybdenum, ene-high-temperature oxidation resistance and high-temperature-high-temperature, ifanelekile kwimibhobho yebhoyili ye-ultra-high-high-pressure.
Ingxubevange yolwakhiwo amabakala entsimbi
I-alloy structural steel grade ye-GB / T5310 standard seamless steel pipes iquka i-15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, njl. Ezi zigaba zemibhobho yentsimbi zineepropati ezahlukeneyo zomatshini kunye noluhlu olusebenzayo ngokweendlela ezahlukeneyo zonyango lwemichiza :
I-15MoG kunye ne-20MoG: Ukongezwa kwexabiso elifanelekileyo le-molybdenum liphucula kakhulu amandla okushisa aphezulu kunye nokumelana nokubola kombhobho wensimbi.
12CrMoG kunye15CrMoG: Ukongezwa kwe-chromium kunye ne-molybdenum kwandisa ukuxhathisa kwe-oxidation kunye namandla aphezulu obushushu bombhobho wensimbi, kwaye ifanelekile kwiindawo ezinokushisa okuphezulu kunye noxinzelelo.
I-12Cr2MoG kunye ne-12CrMoVG: Ukwakhiwa kwe-alloy kuphuculwe ngakumbi, kunye namandla obushushu obuphezulu kunye nokumelana ne-oxidation, kwaye iqhuba kakuhle ngokukodwa kwiindawo eziphakamileyo.
Usetyenziso
I-GB/T5310 imibhobho yentsimbi esemgangathweni engenamthungo isetyenziswa kakhulu kwibhoyila yebhoyila kunye nokutshintshana kobushushu, ikakhulu kubushushu obuphezulu kunye nezixhobo zoxinzelelo oluphezulu ezifana nezibhoyila zesikhululo samandla, iibhoyila zemizi-mveliso, kunye neebhoyila zobushushu benkunkuma.Le mibhobho yensimbi engenamthungo inokumelana noxinzelelo oluphezulu kakhulu lokusebenza kunye namaqondo obushushu, iqinisekisa ukusebenza ngokufanelekileyo kunye nobomi obude beebhoyili kunye nabatshintshisi bobushushu.Ukongezelela, le mibhobho yensimbi iphinda isetyenziswe kwizixhobo zokutshintshiselana kobushushu kwishishini le-petrochemical, ngakumbi ukwandisa iindawo zabo zesicelo.
Isishwankathelo
Imibhobho ye-GB/T5310 esemgangathweni yentsimbi engenamthungo ibe yimveliso ekhethwayo yoxinzelelo oluphezulu nangaphezulu kwemibhobho yebhoyila yomphunga ngenxa yezinto ezigqwesileyo zezinto eziphathekayo kunye noluhlu olubanzi lwezicelo.Nokuba yi-20G, i-20Mg, i-20MoG, i-12CrMoG kunye nezinye izinto, okanye i-15MoG, i-20MoG, i-12CrMoG kunye namanye amabakala ensimbi ye-alloy, zonke zibonisa ukuxhathisa okuphezulu kwe-oxidation kunye namandla aphezulu obushushu, ukunika iziqinisekiso ezithembekileyo zokusebenza ngokukhuselekileyo nokusebenzayo. izixhobo zoshishino.
