Ukumelana nokubola kombhobho wentsimbi ekhandiweyo eTshayina
Ngenxa yokuba umbhobho wentsimbi engenamthungo wediphu ushushu-dip uyigalvanized, umyinge wegalvanized uphezulu kakhulu. Umyinge wobunzima bomaleko owenziwe ngamazinki ungaphezulu kwama-microns angama-65, kwaye ukuxhathisa kwayo kokubola kwahluke kakhulu kunombhobho owenziwe ngamazinki ashushu. Abavelisi bemibhobho ehlala igalvanized rhoqo bavumelekile ukuba basebenzise imibhobho enamanzi abandayo njengemibhobho yamanzi neyegesi. Uluhlu lwezinki lombhobho wensimbi obandayo luluhlu lwe-electroplating, kwaye i-zinc layer ihlukaniswe kwi-substrate yombhobho wensimbi. Uluhlu lwe-zinc luncinci, kwaye i-zinc layer ifakwe nje kwi-matrix yombhobho wensimbi, ekulula ukuwa. Ke ngoko, ukuxhathisa kwayo kukonakala. Kwizindlu ezitsha, akuvumelekanga ukusebenzisa imibhobho yentsimbi ebandayo njengemibhobho yentsimbi yokubonelela ngamanzi. Emva kokuchola, imibhobho yensimbi engenamthungo ye-API icocwa kwi-ammonium chloride okanye i-zinc chloride isisombululo se-aqueous okanye i-ammonium chloride kunye ne-zinc chloride exutywe kwitanki yesisombululo esinamanzi. Ukuze kuqinisekiswe umgangatho, i-electro galvanizing (i-cold plating) ayisetyenziswa kakhulu. Kuphela loo mashishini amancinci anezixhobo ezincinci kunye nezixhobo ezindala asebenzisa i-electro galvanizing, ngokuqinisekileyo, ixabiso labo lincinci. UMphathiswa wolwakhiwo uphelise ngokusesikweni umbhobho wegalvanized ongasemva obandayo, ongazukwenziwa i-electrogalvanized kwixesha elizayo. Kukwenza isinyithi esityhidiweyo siphendule nge-matrix yentsimbi ukuvelisa i-alloy layer, ukwenzela ukudibanisa i-matrix kunye ne-coating. Idiphu eshushu yokugalela intsimbi kukuchola umbhobho wentsimbi kuqala, ukuze kususwe ioksidi yentsimbi kumphezulu wombhobho wentsimbi, uze uyithumele kwitanki yokugalela idiphu eshushu. I-Hot dip galvanizing ineenzuzo zokugquma okufanayo, ukunamathela okuqinileyo kunye nobomi benkonzo ende. 1. Iyunithi yepleyiti ephakathi: ivelisa ubukhulu becala iipleyiti ezibanzi nezityebileyo zokuvelisa imibhobho edityanisiweyo ye-arc yobude. I-longitudinal submerged arc welded pipes inomgangatho othembekileyo kwaye isetyenziswa ngokubanzi kumgca oyintloko we-oyile kunye negesi yokuhanjiswa koxinzelelo oluphezulu.
I-Steckel Mill:I-Steckel mill ibandakanya i-rociprocating roughing mill kunye ne-4-high reciprocating finishing mill. Iipilisi ezimbini ezishushu zekhoyili zifakwe kwimigca yokuhambisa kumacala omabini omatshini wokugqiba. Itheyibhile ye-roller ye-output idla ngokubandakanya inkqubo yokupholisa i-laminar kunye nesikhululo se-coiling. Kwilitye lokusila le-steckel, imbali ye-thermomechanical yobude bentsimbi engenastainless stamping ingqiniba yofakelo lwengqiniba itshintsha kakhulu, ngakumbi kwimveliso ye-micro stainless steel stainless stamping elbow fittings, nto leyo eya kuchaphazela ngamandla isidanga so recrystallization, ukukhula kweenkozo kunye nemvula ekugqityweni. ilitye lokusila, kwaye ikhokelele kutshintsho olumandla kwi-microstructure yokugqibela kunye neepropathi zobude bentsimbi engenastainless izitampu zofakelo lombhobho we-elbow.
Semi continuous Mill:kuquka i-1 Steckel mill kunye ne-5 yokugqiba i-mill. Kwilitye lokusila elingaqhubekiyo, ukuqengqeleka okushushu kofakelo lwemibhobho ekugqityweni kokupasa kuyaguquguquka ukusuka kwelinye icala ukuya kwelinye. Ixesha eliphakathi kokudlula kwilitye lokugqiba lidla ngokuba ngaphantsi kwe-3S.
I-CSP eqhubekekayo ukuphosa nokuqengqeleka:kwintsimbi ephantsi yekhabhoni yemanganese equlathe i-niobium, i-vanadium kunye ne-titanium composite I-Microalloying kumgca wokuvelisa we-CSP, ukuqengqeleka okufanelekileyo okulawulwayo, ukupholisa okulawulwayo kunye neenkqubo zokujija kunokuqinisekisa ukuba iipropati zoomatshini kunye ne-microstructure yofakelo lwemibhobho iyahlangabezana neemfuno zobugcisa zengqiniba ye-X60 yentsimbi engenastainless stamping kwaye indlela yophuhliso lwezifakelo zemibhobho yengqiniba yentsimbi yanamhlanje. I-CSP yaseChina eqhubekayo yokuphosa kunye nomgca wemveliso uphuhlise i-X60 yensimbi engenasici yokudibanisa i-elbow fittings, ngelixa abanye abavelisi be-CSP e-United States nakwamanye amazwe baye baphuhlisa kwaye bavelisa i-high-grade steel stainless stamping elbow fittings X60, X65 kunye ne-X70. Inkqubo yenkqubo kukuba kukho ulwahlulo oluphakathi kwi-slab eqhubekayo yokuphosa. Ukupheliswa kocalucalulo olusembindini ekuqhubeni ukuphosa isilabhu esibhityileyo ngombhobho wentsimbi engenamthungo yingxaki engundoqo yobugcisa ukuqhubela phambili nokuphucula umgangatho wentsimbi engenastainless izitampu zofakelo lwengqiniba. Iipleyiti ezisetyenziselwa i-stainless steel stamping elbow zisetyenziswa ikakhulu i-A3 kunye ne-16Mn eveliswe ngu-Angang kunye nabanye abavelisi kwi-1960 kunye ne-1970s. Ngokunyuka kwedayamitha yombhobho kunye noxinzelelo lokuhambisa, Amandla epleyiti yokufaka umbhobho akakwazi ukuhlangabezana neemfuno. Emva kweminyaka yoo-1980, zonke iifektri zepetroleum ezidityanisiweyo zemibhobho zaqala ukusebenzisa iipleyiti zentsimbi zemibhobho eziveliswe ngokwemigangatho ye-API yaseMelika. Ngelo xesha, ngenxa yetekhnoloji engekavuthwa yabenzi beepleyiti zentsimbi yasekhaya estainless stamping engqiniba, iipleyiti ezisuka kwamanye amazwe zazisetyenziswa ikakhulu.
