I-diain enkulu yentsimbi engenasithulo yentsimbi

Imoda 400 yi-Nickel-Coper Allorety, ikakhulu idityaniswe nge-nickel (malunga ne-63%) kunye nobhedu (malunga ne-28-34%), kwaye iqulethe imali encinci yentsimbi, i-manganese, ikharbon kunye nesilicon. Eli alloy lisetyenziswa ngokubanzi kwimimandla eyahlukeneyo yeshishini ngenxa yokunganyangeki kwe-corosions yayo kunye neepropathi zoomatshini.

Umbhobho wentsimbi ye-carbon womelele kakhulu, ukunganyangeki kwempembelelo kwaye akukho lula ukubola. Ihlala isetyenziswa kwizakhiwo kunye neebhulorho, umkhondo kunye nemveliso yemveliso kunye ne-automotole.

I-carbon skel inamandla amakhulu e-thensile kuyo nayiphi na impahla. Inokugoba kwaye yolule kuyo nayiphi na imilo ngaphandle kokuphulukana namandla. Sebenzisa eli nqaku, umbhobho wensimbi ye-carbon unokuba mncinci kwaye ugcine amandla okuquka izixhobo zokuhamba phantsi koxinzelelo oluphezulu.

Iityhubhu ze-weldied ze-weldied zinabadidi olusebenziseka kakhulu njengoko zinokuba zizinto ezincinci kwaye ezinkulu zentsimbi zineendidi ezininzi: ILasw, SSAW, yejwayi.

I-A106 umbhobho wentsimbi engenamthungo ngumbhobho wentsimbi engenamthungo oveliswe ngokungqinelana noluntu lwaseMelika luvavanyo kunye nezixhobo (i-ASTM). Lo mgangatho ucacisa izinto, ubungakanani, inkqubo yokwenziwa, iipropathi zoomatshini kunye nezinye iimfuno zemibhobho yentsimbi, ijolise ekuqinisekiseni imibhobho kunye nokuthembeka kwemibhobho yentsimbi kwizicelo ezahlukeneyo zeShishini.

Imibhobho yentsimbi engenasifo ihlala isetyenziswa kwiindawo ezininzi ezinobuntu ngenxa yomsebenzi obalaseleyo wokulwa, ukuze imiphetshu isetyenziselwa iminyaka emide kuneminye imibhobho yentsimbi ephezulu yentsimbi iminyaka.

Umbhobho wentsimbi ye-Allow luhlobo lombhobho we-carbon, inombhobho ofanayo we-carbon ye-carbon, kodwa ikwanjalo ikwayamahluko.

I-carbon pipe yensimbi yile nto ivakalayo-i-pipe yenziwe kwi-carbon yentsimbi, i-Steel Aloloty eneentsimbi kunye nekhabhoni. Izinto ezihlalayo ezomeleleyo, umbhobho wentsimbi yekharbon usetyenziswa kumashishini anzima njengezibonelelo, ukuthunyelwa kunye nokuchumisa kwamachiza. Umxholo wekhabhoni ephezulu unika intsimbi yentsimbi ephantsi, esenza ukuba ibe yinto engathandekiyo kwaye iqine kwaye ikwazi ukusasaza ubushushu.

I-API 5l ye-GAGAND i-pipe ngumphunga onomaleko we-zinc kumphezulu wombhobho wentsimbi. Ubukho bohlobo lwe-zinc kunika i-pivanity yombhobho wokunganyangeki. Iipropathi zeekhemikhali ze-zinc zisebenza ngakumbi kunensimbi. Kwindawo ebonakalayo, i-zinc iya kunyanzelisa i-iron, ngaloo ndlela ikhusela i-matrix yombhobho wensimbi evela kwi-corrosion.

Intsimbi engenasimo inesingqala sokuxhaphaza kunye nokunganyangeki okuhle. Ngenxa yokusekwa kwe-chromium engasebenziyo ye-chromium oxide (CR2O3) kumphezulu wensimbi engenasimo, le filimu inamathele kumhlaba wesinyithi kwaye isebenza njengesithintelo

I-carbon stiel stiel ye-welding kunye netyhubhu isetyenziswa kwiimeko zoxinzelelo oluphezulu. Banganyangeki kakhulu ukothusa kunye nokuhambahamba, kubenza balungele ukuthobela ulwelo.

Umbhobho wentsimbi ye-carbon womelele kakhulu, ukunganyangeki kwempembelelo kwaye akukho lula ukubola. I-CS ikwalingana phantsi kwenkcazo yentsimbi yentsimbi, kodwa umahluko omkhulu ukwindlela yokwenza. Inziwa ngokuqengqeleka, inyanzela, kunye nokuzoba iindlela.

Imibhobho yentsimbi engenamthungo yi-Iron Carbon Allow ene-carbon yomxholo we-0.0218% ~ 2.11%. Ibizwa ngokuba yi-carbon sensi. Umbhobho wentsimbi engenamthungo luhlobo lombhobho wentsimbi esekwe kwiseti, apho kungekho manqanaba adibeneyo kwinxalenye engenanto. Njengoko i-china yokuqala yeNkonzo yeKlasi yokuqala, siya kubeka umgangatho wemveliso kunye nenkonzo kuqala.

I-SSAW yentsimbi yentsimbi kwinkqubo yemveliso, kufuneka sinikele ingqalelo kungcelele lwemicimbi. Ngaphandle kwezi zinto zilandelayo zovavanyo zilandelayo, ngokomgangatho we-API kunye neminye imigangatho efanelekileyo yabanye abasebenzisi, kodwa nemfuno yentsimbi yentsimbi, kunye nokuhlolwa kwe-chills kwi-100% ye-100% yentsimbi.

Imibhobho yentsimbi yecarbon inamabakala amaninzi okwanelisa izicelo ezahlukeneyo. I-A53 B, i-A53 B, i-A106b.alitions ye-Chemic Steec, i-A10

Intsimbi ye-carbon inamandla amakhulu e-thensile kuyo nayiphi na impahla. Inokugoba kwaye yolule kuyo nayiphi na imilo ngaphandle kokuphulukana namandla. Sebenzisa eli nqaku, umbhobho wensimbi ye-carbon unokuba mncinci kwaye ugcine amandla okuquka izixhobo zokuhamba phantsi koxinzelelo oluphezulu.

I-A790 i-dupplex yentsimbi yentsimbi yohlobo olukhethekileyo lombhobho wentsimbi engenanto, i-Microsta i-Microsse ibekwe ikakhulu i-austedite kunye nefreyiti.

Imibhobho isetyenziswa ekwakhiweni, ukuthutha kunye nemveliso. Balinganiswa ngokobubanzi babo bangaphandle, kunye needayari zangaphakathi ezingafaniyo ngokusekwe kubuncwane bodonga. Ezinye izicelo zifuna iindonga ezingaphezulu kunezinye, kuxhomekeka kwimikhosi yombhobho kufuneka ilawule.

Izicelo zoxinzelelo oluphantsi azifuni imibhobho yokuba namandla aphezulu kuba azivezwanga kuxinzelelo olukhulu. Ubungakanani bomhlaba obunqabileyo buvumela ukwenziwa kwexabiso eliphantsi. Izicelo ezizodwa ezikhethekileyo-ezinje ngemibhobho esetyenziswe kwi-oyile kunye nerhasi-ifuna ukuqiqa okuthe kratya.

I-Alo Alloty yensimbi ye-ALTM A335 ALTE STERER ye-ASME B36.10

Umbhobho wentsimbi ye-carbon ungoyena mntu usetyenziswa kakhulu kweyona misebenzi isetyenziswayo kunye nexabiso elifanelekileyo.erw yexabiso le-pipes yensimbi, kwaye i-erw ngolona hlobo lusetyenzisiweyo.

I-carbon sky yi-alloy enekharbon kunye nentsimbi, ngomxholo wekhabhoni ukuya kwi-2.1% ngokobunzima.

Izinto ezingafunekiyo zombhobho wensimbi ye-SSAW zibandakanya i-coil yentsimbi, i-welding wire, i-flux. Zonke izinto ezingafunekiyo kufuneka zigqitywe ngokungqongqo komzimba kunye neekhemikhali phambi kotyalo-mali.

  I-carbon skel inamandla amakhulu e-thensile kuyo nayiphi na impahla. Inokugoba kwaye yolule kuyo nayiphi na imilo ngaphandle kokuphulukana namandla. Sebenzisa eli nqaku, umbhobho wensimbi ye-carbon unokuba mncinci kwaye ugcine amandla okuquka izixhobo zokuhamba phantsi koxinzelelo oluphezulu.

Xa sithetha ngombhobho wobubanzi bedayamitha, ihlala ibhekisa kumbhobho kwi-weldid efana ne-lessaw yombhobho okanye umbhobho we-SSAW; Ngaphezulu, ikwabandakanya umbhobho omkhulu ongenamthungo kwezinye iimeko. Iya kuqatshelwa ukuba i-piholi yoxinzelelo oluphezulu lwe-dieameter ongenangqondo kukhethwa.

I-P265GH HACBON PAEL I-PAEL sisitya senqanawa sinamandla aphezulu, ubunzima obuphakamileyo kunye nokusebenza okuhle kwelding. Ineempawu ezintle ezenza zasetyenziswa ngokubanzi kwizicelo ezahlukeneyo zeshishini.

I-ASTM A335 I-Altty Pipe yentsimbi yindawo yentsimbi ye-alloy eveliswa ngokungqinelana ne-A335 yomgangatho omiselwe nguMbutho waseMelika ukuba uvavanywe kunye nezixhobo (i-ASTM).
