Izindaba - I-API 5L Line Pipe:Umhlahlandlela Ophelele Wokubunjwa Kwekhemikhali nokusebenza

Isingeniso:

I-API 5L iwuphawu olujwayelekile olusungulwe i-American Petroleum Institute (API) lwamapayipi ensimbi angenamthungo nashikelwe asetshenziswa ezinhlelweni zokuthutha ngaphakathi kwezimboni ze-petroleum negesi yemvelo.I-Womic Steel, umkhiqizi ohamba phambili wamapayipi olayini we-API 5L, unikeza uhla olubanzi lwemikhiqizo ehlangabezana namabanga ahlukahlukene kanye nokucaciswa.Lesi sihloko sinikeza ukuqhathanisa okuningiliziwe kokwakheka kwamakhemikhali, izakhiwo zemishini, namazinga okuhlola amamaki ahlukene e-API 5L, womabili i-PSL1 ne-PSL2 kuzo zonke izinhlobo ezintathu zamapayipi: ERW (Electric Resistance Welded), LSAW (Longitudinal Submerged Arc Welded), kanye ne-SMLS (Engenamthungo).

Amandla Wokukhiqiza Nobubanzi:
