I-Stainess yentsimbi yentsimbi yentsimbi yentsimbi

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.

Imibhobho yentsimbi engenamthungo isuselwa kwintsimbi eqinileyo esekwe kwiphepha lesizwe esiqinileyo esaziwa ngokuba "zii-billets" ezifudumeleyo kwaye ziphoswe i-roub ye-roub.

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.

Yintoni umbhobho wentsimbi ye-alloy kunye nento malunga nokuchazwa kunye nezibonelelo zayo.

I-SSAW yentsimbi yentsimbi (i-SPIRAL i-arc ye-pipe yensibho yentsimbi) yenziwa ngokutyibilikiswa kwe-sping roul, kunye nombhobho weSpiral Dipe, kunye ne-SPIL PAIM PIP ye-ARC ye-Arc engaphakathi kunye namalungu asezantsi.

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

Umbhobho wentsimbi ye-carbon womelele kakhulu, ukunganyangeki kwempembelelo kwaye akukho lula ukubola.

I-carbon skel inepropathi elungileyo kubukhali namandla, kwaye ayibizi kakhulu kunezinye izithambisi. Ukunyuka kwepesenti yecarbon kuyakuphakamisa ubunzima kunye namandla, kodwa kuya kuba kukungabi ngaphantsi.

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

Umbhobho wombane we-Welding we-Weldied (i-Erw) yenziwa ngababandayo, ukubanda kube yintsimbi yentsimbi kwi-tube ejikelezileyo kwaye uyikhuphe ngothotho lwe-risles ukufumana umthungo. Imiphetho emibini ke yenzelwa ngaxeshanye ngokufudunyezeleka ngaxeshanye ngefreyimu ephezulu kwaye icekeceke kunye ukwenza iqhina. I-Erw Seam Seam ayifuni intsimbi yefilitha.

Umbhobho wentsimbi ye-carbon unelona nqanaba lisetyenzisiweyo ngokubanzi ngenxa yemisebenzi eninzi kunye nexabiso elifikelelweyo

I-Asme B36.10 I-Butt Wood Doipe engenasithumbi inamandla, ukunganyangeki kwempembelelo kwaye akukho lula ukubola. . Inokugoba kwaye yolule kuyo nayiphi na imilo ngaphandle kokuphulukana namandla.

Imibhobho yentsimbi ye-Allow yinto enye inokukhethwa kumbhobho wentsimbi.Imibhobho yentsimbi ye-Allow iyafana nombhobho we-carbon ofanayo kodwa usenawo umahluko.

Umbhobho wentsimbi ye-Allow luhlobo lombhobho we-carbon, unombhobho ofanayo wombhobho wekhabhoni ye-carbon, kodwa ikwayamahluko okhethekileyo.astm A355 imele imibhobho yentsimbi kwaye igobe kwimigangatho yaseMelika.

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-diain enkulu yentsimbi engenasithulo yentsimbi

I-ASTM A312 i-T304 \ / 304l \ / 304h, 316 \ / 316 i-310l, i-310l, i-310l, i-310l, i-S3180, 32750, i-S32550

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.

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

I-API 5l B i-pipe yentsimbi yintsimbi ende enecandelo elinomnqamlezo kwaye akukho mthungi zijikeleze. Yenziwe ngentsimbi yekhabhoni. I-carbon intsimbi yi-iron-carbon alloy ene-iron njenge-matrix kunye nekhabhoni njengeyona nto iphambili. Umbhobho wentsimbi ye-carbon unamandla aphezulu kwaye unokumelana noxinzelelo oluthile kunye noxinzelelo.

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.

I-A53 yintsimbi yekharbon efana ne-A106 B ekuqulunqweni kweekhemikhali kunye nemveliso. Nangona kunjalo, i-A106 ye-A106 kufuneka ibe ngaphandle ngelixa i-a53 yombhobho enokuba yeyokufihlakeleyo okanye idyile.

Intsimbi enganyangekiyo kwimithombo yeendaba ebuthathaka ye-courrosveves efana nomoya, isitya kunye namanzi okanye intsimbi engenazinzi kubizwa ngokuba yintsimbi engenasiseko. Umbhobho wentsimbi engenamthungo luhlobo lombhobho wentsimbi esekwe kwiseti, apho kungekho manqanaba adibeneyo kwinxalenye engenanto. Umbhobho wentsimbi ye-Well yimveliso ye-tublar eyenziwe ngeplate eflethi, eyileweyo, igobile kwaye ilungele ukwelding.

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.

I-carbon ye-carbon yentsimbi kunye nokukwazi ukumelana noxinzelelo, umbhobho wentsimbi ye-carbon usetyenziswa kwiintlobo ngeentlobo zamashishini anzima njengezibonelelo, iinqanawa, izixhobo zokuchumisa izichumisi.

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.

Ububanzi bayo bangaphakathi be-carbon yentsimbi buye bakhulu kunezo ezinye izinto ezinje ngobhedu okanye ngeplastiki, ngoko ke umthamo werhasi uyamkhulu.

I-ASTM A106 i-A106 isetyenziswa rhoqo kumaqondo obushushu aphezulu kunye neenkqubo zoxinzelelo zendlela. Yeyona ntlobo ixhaphakileyo ye-carbon ye-carbon yentsimbi kwishishini namhlanje. I-A106 ye-A106 ye-B ilungele ukugoba, ibeka i-welding, i-welding kunye neyo.

I-90 degree i-pume yentsimbi kukutshintsha umkhombandlela wamanzi ngama-90 isidanga, sikwabizwa ngokuba luhlobo oluthe nkqo kuyo yonke inkqubo esetyenziswayo, kuba kulula ukwakhiwa kwentsimbi kunye nesakhiwo. Umsebenzi wayo kukutshintsha umkhombandlela we-fluid ngama-90 degrees, oko kukwabizwa ngokuba luhlaza.

Umbhobho wentsimbi ongenamthungo luhlobo oluthandwayo lwemibhobho ngenxa yomsebenzi we-AN-TI ongumsebenzi we-AN-TIOY luhlobo lombhobho wekhabhoni, kodwa ikwanayo umahluko othile.
