    Inkcazo emfutshane:

     

    Ukukhetha ngokufanelekileyo izixhobo kubalulekile ukuqinisekisa ukusebenza kakuhle kunye nobude benkqubo yakho yokuhambisa amanzi amdaka. Phakathi kweendlela ezahlukeneyo ezikhoyo, umbhobho wentsimbi we-A252 GRADE 2 waziwa ngamandla awo aphezulu kunye nokuqina kwawo kwaye uye waba lukhetho oludumileyo lokwakha imibhobho yokuhambisa amanzi amdaka ephindwe kabini engaphantsi komhlaba (i-DSAW). Ukudibanisa amandla ombhobho wentsimbi we-A252 GRADE 2 kunye nokuthembeka kwetekhnoloji yokuhambisa amanzi ye-DSAW kudala iziseko zophuhliso zokuhambisa amanzi amdaka ezisebenzayo. Kule bhlog, siza kuhlola iimpawu eziphambili, iingenelo kunye nokusetyenziswa kombhobho wentsimbi we-A252 GRADE 2 kwiiprojekthi zokuhambisa amanzi amdaka ze-DSAW.

    Iithegi zeMveliso

    Funda ngePipe yeNsimbi yeBanga lesi-2 ye-A252:

    Umbhobho wentsimbi we-A252 GRADE 2yipayipi yentsimbi yekhabhoni eyenzelwe ngokukodwa ukusetyenziswa kwiipayipi zoxinzelelo kunye nokusetyenziswa kwezakhiwo. Yenziwe ngokwemigangatho ye-ASTM (American Society for Testing and Materials), iqinisekisa imigangatho yomgangatho ophezulu kunye nokuchaneka kobukhulu. Igama leBAKALA 2 libonisa ukuba ipayipi yentsimbi yenziwe kusetyenziswa iindlela zokuwelda ezingaphantsi komhlaba okanye iindlela zokuwelda ezingenamthungo.

    Ukubaluleka kokuwelda i-arc engaphantsi kwamanzi kabini:

    Ukuwelda kwe-arc engaphantsi kwamanzi kabini, eyaziwa ngokuba yi-DSAW, yinkqubo yokuwelda ekhethekileyo esetyenziselwa ukudibanisa amacandelo ombhobho wentsimbi we-A252 GRADE 2. I-DSAW inika iingenelo ezininzi kunezinye iindlela zokuwelda, kubandakanya ukuthembeka okugqwesileyo kokuwelda, isantya esiphezulu sokuwelda, ukugqwetheka okuncinci, kunye nolawulo olugqwesileyo lokufaka ubushushu. Iqinisekisa ukubopha okuqinileyo phakathi kwemibhobho, okwenza ukuba ingavuzi kakhulu, ibole kwaye yonakale kwisakhiwo.

    Kutheni usebenzisa umbhobho wentsimbi we-A252 Grade 2 kwiiprojekthi zomjelo wamanzi amdaka?

    1. AMANDLA AGQIBELELEYO NOKUBAMBA OKUQINILEYO: Umbhobho wentsimbi i-A252 GRADE 2 unamandla aphezulu okutsalwa, okwenza ukuba ungathintelwa ziingcinezelo zangaphandle kunye noxinzelelo. Ukuqina kwawo kuqinisekisa ubomi benkonzo ende, kunciphisa isidingo sokutshintshwa okanye ukulungiswa rhoqo.

    2. Ukumelana Nokugqwala: Umbhobho wentsimbi we-A252 GRADE 2 wenzelwe ukumelana neemeko ezinzima zangaphantsi komhlaba, kuquka ukuchatshazelwa lindle, iikhemikhali kunye nokufuma, ngaphandle kokugqwala okanye ukonakala. Olu phawu luyandisa kakhulu ubomi benkonzo yemibhobho yendle.

    3. Ixabiso eliphantsi: Umbhobho wentsimbi we-A252 Grade 2 ubonelela ngesisombululo esingabizi kakhulu sokwakhiwa kwemibhobho yamanzi amdaka. Iimfuno zabo zokugcinwa eziphantsi kunye nobomi obude zinokonga oomasipala kunye nabakhi beeprojekthi ukonga okukhulu ngokuhamba kwexesha.

    Iinkqubo zokuWelda iipayipi

    Ukusetyenziswa kombhobho wentsimbi webanga lesi-2 we-A252 kubunjineli bomjelo wamanzi amdaka:

    Umbhobho wentsimbi we-A252 GRADE 2 usetyenziswa kakhulu kwiiprojekthi ezahlukeneyo zeziseko zophuhliso lwemijelo yamanzi amdaka, kuquka:
