Iindaba - I-API 5L Line Pipe: Isikhokelo esipheleleyo soBume beeKhemikhali kunye nokusebenza kwazo

Intshayelelo:

I-API 5L yinkcazo esemgangathweni esekwe yi-American Petroleum Institute (API) yeepayipi zentsimbi ezingenamthungo nezihlanganisiweyo ezisetyenziswa kwiinkqubo zothutho ngaphakathi kwimizi-mveliso yepetroleum kunye negesi yendalo. I-Womic Steel, umenzi ophambili weepayipi zomgca we-API 5L, inikezela uluhlu olubanzi lweemveliso ezihlangabezana namanqanaba kunye neenkcukacha ezahlukeneyo. Eli nqaku libonelela ngothelekiso oluneenkcukacha lwendlela yokwakheka kweekhemikhali, iipropati zoomatshini, kunye nemigangatho yovavanyo yamanqanaba ahlukeneyo e-API 5L, zombini i-PSL1 kunye ne-PSL2 kwiintlobo ezintathu zeepayipi: i-ERW (Electric Resistance Welded), i-LSAW (Longitudinal Submerged Arc Welded), kunye ne-SMLS (Seamless).

Amandla eMveliso kunye noLuhlu:
