Ukusetyenziswa okubanzi kwemibhobho yensimbi engenamthungo kwiindawo zoshishino kunye nokwakhiwa kwenza imigangatho yayo kunye neemfuno zomgangatho zibaluleke kakhulu. Into ebizwa ngokuba "yimibhobho emithathu esemgangathweni" ibhekiselele kwimibhobho yentsimbi engenamthungo ehlangabezana nemigangatho emithathu yamazwe ngamazwe, ngokuqhelekileyo kuquka.API(Iziko lePetroleum laseMelika),I-ASTM(Umbutho waseMelika woVavanyo kunye neZixhobo) kunyeASME(uMbutho waseMelika weeNjineli zeMechanical) imigangatho. Olu hlobo lombhobho wensimbi lunokuthembeka okuphezulu kakhulu kunye nokulungelelanisa ngenxa yemigangatho ephezulu kunye neziqinisekiso ezininzi, kwaye isetyenziswa ngokubanzi kumashishini afana neoli, igesi yendalo, iikhemikhali kunye nombane.

Okokuqala, imibhobho yensimbi engenamthungo ye-API isetyenziswa ikakhulu kwishishini leoli kunye negesi, kwaye imigangatho yayo ephambili yile.API 5LkwayeI-API 5CT. Umgangatho we-API 5L uhlanganisa iimfuno zokuvelisa iipayipi zokuhambisa ukuze kuqinisekiswe ukusebenza kwemibhobho kuxinzelelo oluphezulu, ukushisa okuphezulu kunye neendawo ezinobungozi. Umgangatho we-API 5CT ugxile kwi-oyile ye-oyile kunye ne-tubing ukuqinisekisa amandla kunye nokuqina kwemibhobho ngexesha lokugaya kunye nokuveliswa. Imibhobho yentsimbi engenamthungo esemgangathweni ye-API idla ngokuba namandla aphezulu, ukuqina okuphezulu kunye nokumelana nokugqwala okuhle.

Okwesibini, imibhobho yentsimbi engenamthungo ye-ASTM igubungela amasimi amashishini amaninzi, kubandakanya iibhoyila, abatshintshisi bobushushu, izakhiwo zokwakha, njl.I-ASTM A106kwayeI-ASTM A53 yimigangatho emeleyo. I-ASTM A106 ipayipi yensimbi engenamthungo ifanelekile kwizicelo eziphezulu zokushisa kwaye isetyenziswa ngokubanzi kwiinkqubo zemibhobho yokushisa okuphezulu kwizityalo zamandla, iindawo zokucoca kunye nezityalo zamachiza. I-ASTM A53 yombhobho wentsimbi engenamthungo ilungele ukuthuthwa kolwelo oluqhelekileyo, kuquka amanzi, umoya kunye nomphunga. Le migangatho icacisa ngokungqongqo ukubunjwa kweekhemikhali, iipropati zomatshini kunye nokunyamezela komlinganiselo wemibhobho yentsimbi ukuqinisekisa ukuthembeka kwabo kwizicelo ezahlukeneyo.

Okokugqibela, imibhobho yentsimbi engenamthungo ye-ASME isetyenziswa ikakhulu kwiibhoyila kunye neenqanawa zoxinzelelo. I-ASME B31.3 kunye ne-ASME B31.1 yimigangatho emibini ebalulekileyo echaza ukuyila kunye neemfuno zokwenziwa kweenkqubo zemibhobho phantsi koxinzelelo oluphezulu kunye neendawo zokushisa eziphezulu. Umgangatho we-ASME ugxininisa ukhuseleko kunye nokusebenza kwexesha elide lemibhobho yentsimbi kwaye ifanelekile kwizihlandlo ezifuna ukuthembeka okuphezulu kakhulu kunye nokhuseleko, ezifana nezityalo zamandla enyukliya, izityalo zemichiza kunye nezixhobo ezinkulu zemizi-mveliso.

Inzuzo yemibhobho yemigangatho emithathu ilele kwiziqinisekiso zabo ezininzi kunye nokusetyenziswa okubanzi. Ngenxa yokuba bahlangabezana nemigangatho ye-API, ASTM kunye ne-ASME ngexesha elifanayo, olu hlobo lombhobho wensimbi ongenamthungo lunokuhlangabezana neemfuno ezingqongqo zamazwe ahlukeneyo kunye nemimandla kwaye ifanelekile kwiindidi zeemeko zokusebenza ezinzima. Kungakhathaliseki ukuba kuxinzelelo oluphezulu, ubushushu obuphezulu okanye indawo enobungozi, imibhobho yemigangatho emithathu ingabonisa ukusebenza okugqwesileyo ukuqinisekisa ukusebenza okukhuselekileyo kunye nokuzinza kwenkqubo.

Ngamafutshane, njengemveliso ephezulu phakathi kwemibhobho yentsimbi engenamthungo, imibhobho enemigangatho emithathu iye yaba yinto efunekayo kunye nebalulekileyo kumashishini kunye nolwakhiwo kunye neziqinisekiso zabo ezininzi ezisemgangathweni kunye nokusebenza okugqwesileyo. Ukusetyenziswa kwayo okubanzi akugcini nje ukuphucula umgangatho kunye nokukhuseleka kweeprojekthi, kodwa kukhuthaza ukuphuhliswa kunye nokutsha kweteknoloji yezinto zetsimbi. Ukukhetha imibhobho yemigangatho emithathu akukona nje isiqinisekiso somgangatho, kodwa kunye nokuzibophelela ekuzinzeni kwexesha elide kunye nokhuseleko lweprojekthi.
