Kwilizwe lemveliso yentsimbi yentsimbi, imigaqo-nkqubo nemigangatho yokuqonda ibalulekile ekuqinisekiseni umgangatho kunye nokusebenza. Omnye umgangatho onjalo ngu-A139, ochaza iimfuno zombane (i-ARC) ye-WelDed Welded Welded ye-Weel ye-Steel yenkonzo yoxinzelelo oluphezulu. Le bhlog iya kuthatha i-hive enzulu ngqo kwi-ATTM A139 kwaye iphonononge isicelo sayo, ngokukodwa kumbhobho we-S235 J0 oveliswa ngumenzi ophambili eCangzhou, kwiPhondo laseHezei.
Iinkcazo eziphambili ze-ASTM A139
I-ASTM A139Igubungela imiba ebalulekileyo yemveliso yentsimbi yentsimbi, kubandakanya ukwakhiwa kwezixhobo, iipropathi zoomatshini, kunye neendlela zovavanyo. Umgangatho ugxile kwezi ngcaciso zilandelayo:
I-1. Ubume bezinto ezibonakalayo: I-ASTM A139 ichaza ukubekwa kweekhemikhali kwentsimbi esetyenziselwa ukwenza imibhobho. Oku kubandakanya umda ovumelekileyo wezinto ezinjengekhabhoni, i-manganese, iphosphorus, kunye ne-phosfur, kunye ne-phosfur ukuqinisekisa ukuba imibhobho inamandla afanelekileyo kunye nokuqina.
2. Iipropathi zoomatshini: Lo mgangatho ucacisa iipropathi ezifunwayo, kubandakanya amandla esivelwano, amandla obuzini, kunye no-Elongwation. Ezi ndawo zibalulekile ukuqinisekisa ukuba umbhobho unokumelana nokusetyenziswa kweendleko eziphezulu ngaphandle kokusilela.
I-3. Iimfuneko zeWeding: Kuba i-ASTM i-A139 ijongene nemibhobho ye-Welding, kubandakanya ukwemeko yenkqubo ye-welding, kubandakanya i-WIVE ye-WODL, kubandakanya nohlobo lwe-weld, umgangatho wokuqinisekisa ukuba i-welds ifezekisile imigangatho ye-WODS.
4. Iindlela zovavanyo: Umgangatho uphendula ngeendlela zovavanyo ekufuneka ziqeshwe ukuqinisekisa umgangatho kunye nokusebenza kombhobho. Oku kubandakanya iindlela ezingezizo ezonakalisayo zokufumana iziphene kwi-wels okanye kwizixhobo zepayipi.
Ukusetyenziswa kwe-ASTM A139 pipe
Ukusetyenziswa kwe-ASTM A139 imibhobho yentsimbi ibanzi kwaye yahluka, ngakumbi kumashishini afuna iinkqubo zokulinganisa uxinzelelo oluphezulu. Le mibhobho isetyenziselwa ukusetyenziswa:
-Ishishini leoyile negesi: I-ASTM I-A139 imibhobho elungele ukuthutha ioyile kunye negesi kunye nokukwazi kwabo ukumelana noxinzelelo oluphezulu kunye neemeko ezinzima zokusingqongileyo.
Iinkqubo zokubonelela ngamanzi: Ukuqina kunye namandla ale mibhobho zibenza balungele ukusetyenziswa kunikezelo lwamanzi kunye neenkqubo zokuhambisa, ukuqinisekisa ukuhamba kwamanzi athembekileyo.
Ukuqhubekeka kwamachiza: Kwizityalo zekhemikhali, imibhobho ixhomekeke kwizinto ezizodwa kunye ne-ASTM i-A139 imibhobho ye-A139 ibonelela ngokungachanekanga kunye nokuthembeka okuyimfuneko.
Izibonelelo ze-S235 j0umbhobho wentsimbi
Enye yeemveliso ezibalaseleyo eziveliswa yinkampani yethu eCangzhou yi-S235 j0 yentsimbi yentsimbi. Le mveliso iphawuleka ngokukhethekileyo ngenxa yokuguquguquka kwayo kububanzi kunye nokungqinelana kobunzima. Ukulungelelaniswa kwemveliso kwenza ukuba kube lula ukuvelisa imibhobho ende ephezulu kakhulu eneendlela ezahlukeneyo ezihlangabezana neemfuno ezahlukeneyo kumashishini ahlukeneyo.
Kusekwe ngo-1993, emva kweminyaka yophuhliso olukhawulezileyo, inkampani ngoku igubungela indawo engama-350,000 yeemitha, kwaye inamaqela apheleleyo angama-680, kwaye abanabasebenzi abazinikeleyo abangama-680, kwaye babenabasebenzi abazinikeleyo abangama-680, kwaye banabasebenzi abangama-680, kwaye baneempawu ezisemgangathweni eziphezulu njenge-ASTM A139.
ukuququmbela
Ukuqonda i-ATM A139 kunye neenkcazo zayo kubalulekile nakubani na obandakanyekayo kwimveliso yentsimbi yentsimbi. Lo mgangatho awuqinisekisi kuphela umgangatho kunye nokusebenza kombhobho, kodwa uvula uluhlu olubanzi lwezicelo kumashishini ahlukeneyo. Ngeemveliso ezinje nge-S235 j0 i-spiper yentsimbi, inkampani yethu iyaqhubeka ukukhokela indlela ekunikezeleni abathengi kunye nezisombululo eziguqukayo eziguqukayo. Nokuba ukwishishini leoyile kunye negesi, ukuhambisa amanzi okanye ukuqhubekisa kwamachiza, imibhobho yensizi iya kuhlangabezana neemfuno zakho kwaye idlule kulindelo lwakho.
