Ipayipi lensimbi le-ASTM A53 Grade B ERW elinopende obomvu ngaphandle lathunyelwa ngempumelelo eRiyadh ngemuva kokudlula ukuhlolwa.
I-oda lalivela kumakhasimende avamile aseSaudi Arabia abesebenza nathi iminyaka eminingi, ukuze athole imininingwane eminingi.I-ASTM A53 Ibanga B ERW(Uhlobo E) ipayipi lensimbi elinombozo we-epoxy obomvu wangaphandle.
Ipayipi lensimbi le-ASTM A53 Grade B ERW liyipayipi lensimbi yekhabhoni elisetshenziswa kabanzi elinezakhiwo ezinhle zomshini kanye nokwakheka kwamakhemikhali, elivame ukusetshenziswa ekuthuthweni komusi, amanzi, uwoyela, igesi yemvelo, njalo njalo. Lingasetshenziswa ukwenza ama-gond, ama-flange, njll.
I-Botop ibilokhu imatasa ekuxhumaniseni nasekuhlanganiseni ukuqedwa okusheshayo kokwenziwa kwamashubhu. Izakhiwo zemishini, ukwakheka kwamakhemikhali, ukubukeka, ubukhulu, kanye nezinye izakhiwo zamapayipi zihlolwa ngokucophelela ukuqinisekisa ukuhambisana nezindinganiso kanye nezidingo zamakhasimende.
Upende we-epoxy resin ungathuthukisa ukumelana nokugqwala kanye nokumelana nokuguquguquka kwepayipi lensimbi, okungandisa kakhulu impilo yesevisi yepayipi lensimbi. Ukulawulwa kwekhwalithi yopende kwenziwa ngezinto zokusetshenziswa zopende, ukususwa kwesilinganiso, inqubo yokupenda, nezinye izici.
Akukhona nje kuphela ukulawulwa kwekhwalithi yomkhiqizo, kodwa futhi nokuthunyelwa, i-Botop yezokuthutha izoba nabasebenzi okufanele bayiqondise, ukuqinisekisa ukuthi umkhiqizo osesimweni sokuthutha awubonakali wonakele, futhi ungaqedwa futhi ulethwe ngesikhathi ezandleni zamakhasimende.
Ngezansi isithombe senye yamarekhodi esiqukathi.
I-Botop ibilokhu ihileleke kakhulu embonini yamapayipi ensimbi iminyaka eminingi, futhi ukugcizelela kwayo ikhwalithi kanye nedumela elihle kuye kwazuza ukwethenjwa kwamakhasimende amaningi kanye nokuqashelwa emakethe. Ngokubambisana okuseduze namakhasimende, inkampani iqhubeka nokwenza ngcono imikhiqizo nezinsizakalo zayo ukuze ihlangabezane nezidingo zemakethe ezihlala zishintsha.
Uma unezidingo zamapayipi ensimbi, ungaxhumana nathi, ithimba lochwepheshe likulungele ukukukhonza.
Ipayipi lensimbi le-ASTM A53 lenzelwe ukusetshenziswa kwemishini kanye nengcindezi futhi liyamukeleka futhi ekusetshenzisweni okuvamile emisipheni yomusi, amanzi, igesi, kanye nemigqa yomoya. Lifanele ukushisela futhi lifanele ukwenza imisebenzi ehilela ukugoba, ukugoba, kanye nokufulela.
