Ukukhetha uMbhobho oLungileyo we-API yeeMfuno zakho zoShishino

n amashishini ahlukeneyo afana ne-oyile negesi, i-petrochemical, kunye nemveliso, ukukhethwa kombhobho ochanekileyo wokuthutha ulwelo kubalulekile.Imibhobho ye-API engenamthungo ibe lukhetho oludumileyo ngenxa yokuqina, amandla, kunye nokukwazi ukumelana neemeko ezigqithisileyo.Le bhlog iya kukukhokela kwizinto ekufuneka uziqwalasele xa ukhetha umbhobho ofanelekileyo we-API kwiimfuno zakho zoshishino.

Ukuqonda uMbhobho we-API ongenamthungo:

Imibhobho ye-API engenamthungo, eyenziwe ngokuhambelana nemigangatho ebekwe yi-American Petroleum Institute (API), isetyenziswa kakhulu kwishishini leoli kunye negesi.Le mibhobho yenzelwe ukunika amandla aphezulu, ukumelana nokubola, kunye nokubambelela kwiinkqubo ezingqongqo zokuvelisa.Ziza kumabakala ahlukeneyo, kubandakanywa i-API 5L, echaza iimfuno zokwenziwa kwamanqanaba amabini enkcazo yemveliso (PSL 1 kunye ne-PSL 2) yemibhobho yentsimbi engenamthungo kunye ne-welded.

Iingqwalasela kuKhetho lweMibhobho ye-API engenamthungo:

1. IiMfuno ezithe ngqo kwisicelo:
Xa ukhetha umbhobho we-API ongenamthungo, qwalasela iimfuno ezithile zesicelo.Izinto ezinje ngeqondo lobushushu, uxinzelelo, kunye nodidi lolwelo ziya kumisela ibakala kunye neenkcukacha ezifunekayo.Ngokomzekelo, ukuba ujongene nokuthuthwa kwamanzi oxinzelelo oluphezulu, qwalasela umbhobho onomlinganiselo ophezulu, njenge-API SCH 40, enokumelana noxinzelelo oluphezulu xa kuthelekiswa nemibhobho ephantsi.

2. Izinto eziphathekayo kunye neBanga:
Imibhobho ye-API engenamthungo ifumaneka kwizinto ezahlukeneyo, kunye ne-carbon steel iyona nto ikhethwa kakhulu ngenxa yamandla ayo agqwesileyo kunye neendleko-zokusebenza.Nangona kunjalo, ezinye izinto ezifana nentsimbi ye-alloy kunye nensimbi engenasici zingaba yimfuneko kwizicelo ezithile.Qinisekisa ibakala elikhethiweyo, elifana ne-ASTM API 5L, lifanelekile kusetyenziso olujoliswe kuyo, ngokuqwalasela izinto ezifana nokuchasana nokugqwala, ukulinganiselwa kweqondo lokushisa, kunye neempawu zomatshini.

3. Ubungakanani kunye nemilinganiselo:
Ubungakanani kunye nobukhulu bombhobho we-API ongenamthungo nazo zizinto ezibalulekileyo zokumisela.Qwalasela isantya sokuhamba, ukuhla koxinzelelo, kunye nesithuba esikhoyo xa ukhetha i-diameter efanelekileyo kunye nobukhulu.Umbhobho omncinci kakhulu unokubangela uthintelo lokuhamba, ngelixa lowo mkhulu kakhulu unokufumana iindleko ezingeyomfuneko kwaye ubangele ukusebenza okungenamsebenzi.

4. Ukuthotyelwa kweMigangatho kunye neziQinisekiso:
Ngalo lonke ixesha uqinisekise ukuba umbhobho we-API ongenamthungo owukhethayo uhambelana nemigangatho yoshishino efanelekileyo kunye neziqinisekiso.Isiqinisekiso se-API 5L siqinisekisa ukuba umbhobho uhlangabezana neemfuno ezithile zomgangatho, ukusebenza kunye nokuthembeka.Ukukhetha imibhobho evela kubavelisi abathembekileyo abalandela iinkqubo ezifanelekileyo zokulawula umgangatho baya kunika isiqinisekiso sokuthembeka kunye nokuhambelana nemigangatho.
