Kwihlabathi lokwenziwa kwemibhobho yentsimbi, ukuqonda iinkcukacha kunye nemigangatho yoshishino kubalulekile ukuqinisekisa umgangatho kunye nokusebenza. Omnye wemigangatho enjalo yi-ASTM A139, echaza iimfuno zombhobho wentsimbi odibeneyo wombane (i-arc) kwinkonzo yoxinzelelo oluphezulu. Le bhlog iza kujonga nzulu iinkcukacha eziphambili ze-ASTM A139 kwaye ihlolisise ukusetyenziswa kwayo, ngakumbi kumxholo wombhobho wentsimbi ojikelezayo we-S235 J0 owenziwe ngumenzi ophambili eCangzhou, kwiPhondo laseHebei.
Iinkcukacha eziphambili ze-ASTM A139
I-ASTM A139Igubungela iinkalo ezininzi ezibalulekileyo zokwenza imibhobho yentsimbi, kubandakanya ukwakheka kwezinto, iimpawu zoomatshini, kunye neendlela zovavanyo. Umgangatho ugxile kwezi nkcukacha zilandelayo:
1. Ukwakhiwa kwezinto: I-ASTM A139 ichaza ukwakheka kweekhemikhali zentsimbi esetyenziselwa ukwenza imibhobho. Oku kuquka imida evumelekileyo yezinto ezifana nekhabhoni, i-manganese, i-phosphorus, kunye ne-sulfur ukuqinisekisa ukuba imibhobho inamandla kwaye ihlala ixesha elide.
2. Iipropati zoomatshini: Lo mgangatho uchaza iipropati zoomatshini ezifunekayo, kubandakanya amandla okukhupha, amandla okutsalwa, kunye nokwandiswa. Ezi mpawu zibalulekile ukuqinisekisa ukuba umbhobho unokumelana nokusetyenziswa koxinzelelo oluphezulu ngaphandle kokusilela.
3. Iimfuneko zokuwelda: Ekubeni i-ASTM A139 isebenza ngeepayipi zokuwelda, ibandakanya iinkcukacha zenkqubo yokuwelda, kubandakanya uhlobo lokuwelda, umgangatho wokuwelda, kunye neendlela zokuhlola ukuqinisekisa ukuba ukuwelda kuyahlangabezana nemigangatho efunekayo.
4. Iindlela zoVavanyo: Lo mgangatho ukwachaza neendlela zovavanyo ekufuneka zisetyenziswe ukuqinisekisa umgangatho kunye nokusebenza kombhobho. Oku kuquka iindlela zovavanyo ezingatshabalalisiyo ukufumanisa naziphi na iziphene kwi-welds okanye kwizixhobo zombhobho.
Ukusetyenziswa kwe-ASTM A139 Steel Pipe
Ukusetyenziswa kwemibhobho yentsimbi ye-ASTM A139 kubanzi kwaye kwahlukahlukene, ingakumbi kumashishini afuna iinkqubo zemibhobho enoxinzelelo oluphezulu. Le mibhobho isetyenziswa rhoqo kwezi zinto zilandelayo:
- Ishishini leoyile negesi: Imibhobho ye-ASTM A139 ifanelekile ekuthuthweni kweoyile negesi ngenxa yokuba iyakwazi ukumelana noxinzelelo oluphezulu kunye neemeko ezinzima zokusingqongileyo.
- Iinkqubo zoNikezelo lwaManzi: Ukuqina nokomelela kwezi mbhobho kuzenza zilungele ukusetyenziswa kwiinkqubo zoNikezelo lwamanzi nokusasazwa kwamanzi, okuqinisekisa ukuhamba kwamanzi okuthembekileyo.
- Ukucubungula iikhemikhali: Kwizityalo zeekhemikhali, iipayipi zichaphazeleka zizinto ezirhabaxa kwaye iipayipi ze-ASTM A139 zibonelela ngokumelana nokuthembeka okufunekayo.
Iingenelo ze-S235 J0umbhobho wentsimbi ejikelezayo
Enye yeemveliso ezibalaseleyo eziveliswe yinkampani yethu eCangzhou yipayipi yentsimbi ejikelezayo ye-S235 J0. Le mveliso iphawuleka kakhulu ngokuguquguquka kwayo ububanzi kunye neenkcukacha zobukhulu bodonga. Ukuguquguquka kokwenziwa kwayo kwenza ukuba ikwazi ukuvelisa iipayipi ezinodonga oluqinileyo ezikumgangatho ophezulu ezihlangabezana neemfuno ezahlukeneyo zamashishini ahlukeneyo.
Yasekwa ngo-1993, emva kweminyaka yophuhliso olukhawulezileyo, le nkampani ngoku igubungela indawo yeemitha zesikwere ezingama-350,000, inempahla iyonke eyi-RMB 680 yezigidi, kwaye inabasebenzi abazinikeleyo abangama-680, abazibophelele ekuveliseni imibhobho yentsimbi ekumgangatho ophezulu ehlangabezana nemigangatho yamazwe ngamazwe efana ne-ASTM A139.
ukuququmbela
Ukuqonda i-ASTM A139 kunye neenkcukacha zayo kubalulekile kuye nabani na obandakanyeka kwimveliso yeepayipi zentsimbi. Lo mgangatho awuqinisekisi nje kuphela umgangatho kunye nokusebenza kwepayipi, kodwa ukwavula uluhlu olubanzi lwezicelo kwiindidi ezahlukeneyo zamashishini. Ngeemveliso ezifana nepayipi yentsimbi ejikelezayo ye-S235 J0, inkampani yethu iyaqhubeka nokukhokela indlela ekuboneleleni abathengi ngezisombululo eziguquguqukayo nezisemgangathweni ophezulu. Nokuba ukwishishini leoyile negesi, unikezelo lwamanzi okanye ulungiso lweekhemikhali, iipayipi zethu zentsimbi ziya kuhlangabezana neemfuno zakho kwaye zidlule kulindelo lwakho.
