Umbhobho we-API 5L ongenamthungo

I-API 5L yeMibhobho yentsimbi engenamthungo{1}}Ubuchwephesha bokwenza imibhobho ekwinqanaba eliphezulu

Umbhobho we-Octal uvelisa izisombululo ezibanzi ze-API 5L zoMbhobho weMibhobho, oquka zombini imibhobho yentsimbi engenamthungo nedityanisiweyo eyenzelwe i-petroleum kunye neenkqubo zokuthutha igesi yendalo. Amandla ethu emveliso agubungela amabanga ukusuka kwi-API 5L Gr B ukuya kwi-X80, efumaneka kuwo omabini amanqanaba e-PSL1 kunye ne-PSL2. Le mibhobho yenzelwe ukuba ifune unxweme/unxweme kunye nemekobume yenkonzo emuncu (imeko zokonakala kwe-H2S kunye nokuthotyelwa kwe-NACE).
I-API 5L Line Pipe isebenzela amashishini e-oyile negesi anezisombululo zemibhobho eyomeleleyo ephuhliselwe iimeko ezahlukeneyo zokusebenza. Ukwakhiwa kwensimbi yekhabhoni kuhambelana neemfuno ze-API SPEC 5L, ukuqinisekisa ukusebenza okuthembekileyo kwiimeko zokushisa ezigqithiseleyo, iindawo ezinobungozi, kunye nezicelo zenkonzo ezimuncu eziqukethe i-H2S.

Umthungo Steel Line Pipe
