Ifektri Eshibhile Ipayipi Lodonga Olusindayo Elingenamthungo
Incazelo emfushane:
Ipayipi Elingenamthungo le-Heavy Wall Carbon Steel liwuhlobo lwepayipi elinogqinsi oluphakeme kunesilinganiso.Lezi zisetshenziswa ezimbonini ze-petrochemical, izimboni zamakhemikhali kanye nezimboni zamandla enuzi.Singabahlinzeki beshubhu yensimbi ye-carbon steel e-China abahlonishwayo abamelana nezingcindezi ezinzima nezingcindezi ngenxa yamandla odonga.Izicelo zihlanganisa uwoyela negesi, izindawo zocwaningo nentuthuko, imboni yezokuvikela kanye nezigayo ze-pulp nephepha.Ipayipi elisindayo elingenamthungo limakwe ngezinombolo zeshejuli yodonga olusindayo njenge-EH, XH ne-XS.
Ukuqamba izinto ezintsha, okuhle kakhulu kanye nokwethembeka yikona okuwumongo webhizinisi lethu.Lezi zimiso namuhla ngaphezu kwanini ngaphambili zakha isisekelo sempumelelo yethu njengenkampani esebenza emhlabeni wonke yosayizi omaphakathi Yefektri Eshibhile Ewugqinsi Wodonga Oluqinile lwepayipi, Samukela ngobuqotho abangane ukuze baxoxisane ngebhizinisi futhi baqale ukubambisana.Sithemba ukuhlanganisa izandla nabangane ezimbonini ezahlukene ukuze sikhiqize ikusasa elivelele elibonakalayo.
Ukuqamba izinto ezintsha, okuhle kakhulu kanye nokwethembeka yikona okuwumongo webhizinisi lethu.Le migomo namuhla eyengeziwe kunangaphambili yakha isisekelo sempumelelo yethu njengenkampani yamazwe ngamazwe ephakathi nendawoIpayipi Elisindayo LaseShayina kanye Nepayipi Lokuqina Odongeni, Senze izimakethe ezinkulu emazweni amaningi, njengaseYurophu nase-United States, eMpumalanga Yurophu naseMpumalanga Asia.Phakathi naleso sikhathi ngokubusa okunamandla kubantu abanekhono, ukuphathwa okuqinile kokukhiqiza kanye nomqondo webhizinisi.sihlala siqhubeka nokuzenzakalela, ukusungula izinto ezintsha zobuchwepheshe, ukuphatha ukuqamba kanye nokusungula umqondo webhizinisi.Ukulandela imfashini yezimakethe zomhlaba, izimpahla ezintsha zigcinwa ekucwaningeni nasekuhlinzekeni ukuze kuqinisekiswe ukuncintisana kwethu ngezitayela, ikhwalithi, intengo kanye nesevisi.
Kunamashejuli ahlukene kula mapayipi njengoba ephatha amazinga ehlukene okucindezela.Ngokuvamile kukhona ama-sch 80, 100, 120, 140 kanye no-160 anezindonga ezinzima.Ugqinsi olusindayo lwepayipi elingenamthungo kwesinye isikhathi lingaba namandla aphindwe kabili futhi lichazwa ngokuthi XXS noma XXS.Izinto zingahluka njengoba kukhona amamaki ahlukene ensimbi ye-carbon asetshenziselwa ukwenza izinhlobo ezahlukene zamapayipi ensimbi ensimbi.Ivolumu ephezulu, ukugeleza okuphezulu, amasistimu okucindezela okuphezulu njengezintambo zokuhambisa uwoyela negesi, izintambo zamanzi, nezinhlelo zokupholisa zemishini kagesi konke okusetshenzisiwe ngezinhlobo ezahlukene,
Amapayipi ensimbi angenamthungo aminyene asetshenziswa kakhulu endaweni yokonga amanzi, i-petrochemical, amakhemikhali, amandla kagesi, ukuchelela ngenkasa kwezolimo, ukwakhiwa kwamadolobha nezinye izimboni.Okokuthutha okuwuketshezi: ukuhlinzekwa kwamanzi kanye nokukhipha amanzi.Ukuthuthwa kwegesi: igesi yemvelo, umusi, i-liquefied petroleum gas.Ukusetshenziswa kwesakhiwo: kusetshenziswa njengamapayipi okunqwabelanisa ibhuloho;amatheku, imigwaqo, izakhiwo kanye nezinye izakhiwo.
Isihluthulelo sekhwalithi yamapayipi ensimbi anezindonga eziwugqinsi kufanele kube ukufana kokuqina.Ukushuba okungalawuleki kodonga lwamapayipi ensimbi anezindonga eziwugqinsi kuthinta ngokuqondile ikhwalithi nokusebenza kwamapayipi ensimbi, amapayipi ensimbi anezindonga eziwugqinsi, namapayipi ensimbi anobubanzi obukhulu obungenamthungo.Ngokuvamile isetshenziselwa ukucubungula okuhlukahlukene kanye nokucutshungulwa kwezingxenye eziwugqinsi.,, ubukhulu bodonga obufanayo bepayipi lensimbi buzothinta ngokuqondile ikhwalithi yezingxenye ezingemuva kokucubungula, udonga lwepayipi yensimbi enogqinsi alulawulwa, futhi ikhwalithi yonke yensimbi ayiqinile.
Amapayipi ensimbi anezindonga eziwugqinsi abhekisela kumapayipi ensimbi anobubanzi bepayipi nobukhulu bodonga obungaphansi kwama-20. Ikakhulukazi asetshenziselwa amapayipi okubhoboza i-petroleum geological, amapayipi aqhekeka amakhemikhali e-petrochemical, amapayipi abhayela, amapayipi anamapayipi kanye namapayipi anesakhiwo anembe kakhulu ezimoto, ogandaganda kanye. ezondiza.Izinga lamapayipi ensimbi angenamthungo aqinile anezindonga lincike ekufaneni kokuqina kodonga.
I-tube billet eyindilinga → ukushisisa → ukubhoboza → ukugoqeka okuphambana kwamaroli amathathu, ukugoqeka okuqhubekayo noma ukukhishwa → ukuhlubula → ukusika (noma ukunciphisa ububanzi) → ukupholisa → ukuqondisa → ukuhlola okuqhutshwa ngamanzi (noma ukutholwa kwamaphutha) → ukumaka → indawo yokugcina impahla.
Izakhiwo zemishini zamapayipi ensimbi anokuqina kodonga ziyinkomba ebalulekile yokuqinisekisa ukusebenza kokugcina kokusetshenziswa (izakhiwo zemishini) yamapayipi ensimbi okuqina okuqina kwamapayipi ensimbi, futhi kuncike ekubunjweni kwamakhemikhali kanye nesistimu yokwelapha ukushisa kwepayipi lensimbi.Ngakho-ke, ngokuya ngezidingo ezihlukene zohlelo lokusebenza, izici zemishini zamapayipi ensimbi anokuqina odongeni olusindayo zethulwa ngokuqondile ezicini zamandla aqinile, iphuzu lesivuno, kanye nobude.
1. Amandla okuqina
Enqubweni yokuqina, amandla amakhulu (Fb) isampula eliwathwalayo uma liphuka ingcindezi (σ) etholwe endaweni yasekuqaleni ye-cross-sectional (So) yesampula, ebizwa ngokuthi amandla e-tensile (σb), kanye iyunithi ingu-N/mm2 (MPa).Imele ikhono eliphezulu lensimbi yokumelana nokulimala ngaphansi kwamandla aqinile.
2. Iphuzu lesivuno
Okokusebenza kwensimbi okunomphumela wokukhiqiza, ingcindezi lapho isampula ingaqhubeka nokukhula ngaphandle kokukhuphuka kwamandla ngesikhathi senqubo yokwelula (ihlala ingashintshi) ibizwa ngokuthi iphoyinti lokukhiqiza.Uma amandla ehla, amaphuzu okukhiqiza aphezulu naphansi kufanele ahlukaniswe.Iyunithi yephoyinti lesivuno ngu-N/mm2 (MPa).
3. Ukwelula ngemva kokuphuka
Esivivinyweni sokuqina, amaphesenti obude begeji yobude akhuphuka ngemva kokuba isampula sephulwe ukuya kubude begeji yasekuqaleni ibizwa ngokuthi i-elongation.Kuvezwe ngo-σ, iyunithi ithi %.
Ukuqamba izinto ezintsha, okuhle kakhulu kanye nokwethembeka yikona okuwumongo webhizinisi lethu.Lezi zimiso namuhla ngaphezu kwanini ngaphambili zakha isisekelo sempumelelo yethu njengenkampani esebenza emhlabeni wonke yosayizi omaphakathi Yefektri Eshibhile Ewugqinsi Wodonga Oluqinile lwepayipi, Samukela ngobuqotho abangane ukuze baxoxisane ngebhizinisi futhi baqale ukubambisana.Sithemba ukuhlanganisa izandla nabangane ezimbonini ezahlukene ukuze sikhiqize ikusasa elivelele elibonakalayo.
Imboni EshibhileIpayipi Elisindayo LaseShayina kanye Nepayipi Lokuqina Odongeni, Senze izimakethe ezinkulu emazweni amaningi, njengaseYurophu nase-United States, eMpumalanga Yurophu naseMpumalanga Asia.Phakathi naleso sikhathi ngokubusa okunamandla kubantu abanekhono, ukuphathwa okuqinile kokukhiqiza kanye nomqondo webhizinisi.sihlala siqhubeka nokuzenzakalela, ukusungula izinto ezintsha zobuchwepheshe, ukuphatha ukuqamba kanye nokusungula umqondo webhizinisi.Ukulandela imfashini yezimakethe zomhlaba, izimpahla ezintsha zigcinwa ekucwaningeni nasekuhlinzekeni ukuze kuqinisekiswe ukuncintisana kwethu ngezitayela, ikhwalithi, intengo kanye nesevisi.
