API 5LNgumgangatho wombhobho womgca wentsimbi esetyenziselwa ukuthutha ioyile, irhasi yendalo, kunye namanzi. Owona mgangatho ugubungela amabakala ahlukeneyo entsimbi, apho i-X42 ne-X52 ngamanqanaba amabini amanqanaba aqhelekileyo. Umahluko ophambili phakathi kwe-X42 kunye ne-X52 ziimpawu zabo zoomatshini, ngakumbi amandla okuvelisa kunye namandla amanye.

X42: Elona xesha linesivuno se-X42 yentsimbi yi-42,000 ye-PSI (290 MPA), kwaye amandla awo e-sunsle asusela kuma-60,000-75,000 Mpa (415-450 MPA). X42 grade steel pipe is generally used in pipeline systems with medium pressure and strength requirements, suitable for transporting media such as oil, natural gas, and water.

X52: Elona xesha linesivuno se-X52 le-X52 yi-52,000 psi (i-360 MPA), kwaye amandla e-sunsle asusela kwi-66,000-955 000 psi). Xa kuthelekiswa ne-X42, i-X52 imibhobho yentsimbi yeBanga inamandla aphezulu kwaye ilungele iinkqubo zemibhobho kunye neemfuno eziphakamileyo zoxinzelelo kunye neemfuno zomeleleyo.

Ngokwemeko yokuhanjiswa kweenkonzo,I-API 5LIcacisa imeko eyahlukileyo yokuhanjiswa kwemibhobho yentsimbi engenamthungo kunye nemibhobho ye-weldied:

Umbhobho wentsimbi engenamthungo (NULANDELWENI): N I-N State ibhekisele kwimo yonyango eqhelekileyo. Imibhobho yentsimbi engenamthungo iqhelekile ngaphambi kokuziswa e-homogenize i-Microstrage i-Microssuge ibe ngumbhobho wentsimbi, ngaloo ndlela iphucula iipropathi zayo kunye nobuchule bayo. Ukwenza i-filing inokuphelisa uxinzelelo lwentsalela kunye nokuphucula ukuzinza kombhobho wentsimbi.

Umbhobho we-wellded (M urhulumente): M urhulumente ubhekisa kunyango lwe-thermombecal yombhobho we-welding emva kokwenziwa kunye ne-welding. Ngonyango lwe-thermombecal, ubukhulu becala lombhobho we-welding ufanelekile, ukusebenza kwendawo ye-welding kuphuculwe, kwaye amandla kunye nokuthembeka kombhobho we-welding ngexesha lokusetyenziswa kuqinisekisiwe.

I-API 5LIcacisa ngokweenkcukacha ukwakhiwa kweekhemikhali, iipropathi zoomatshini, iindlela zokwenza izinto, ukuhlolwa kunye neemfuno zovavanyo zemibhobho ye-pipeline. Ukuphunyezwa komgangatho kuqinisekisa ukhuseleko kunye nokuthembeka kwemibhobho ye-pipeline xa uhambisa i-oyile, igesi yendalo kunye nolunye ulwelo. Ukukhethwa kwamabakala afanelekileyo emibhobho yentsimbi kunye nenqanaba lokuhanjiswa kweenkonzo kunokuhlangabezana neemfuno ezithile zeeprojekthi zobunjineli bobunjineli kunye nokuqinisekisa ukusebenza okuzinzileyo kwenkqubo yepayipi.
