I-AWWA Butterfly Valve DN1000 Inikezelwe kwiProjekthi yeNqaba yokuPholisa eSaudi Arabia

Isishwankathelo seMveliso

I-Nortech Engineering Corporation igqibile ukuhambisa iiyunithi ezingama-37 zevalvu yebhabhathane ephindwe kabini eyilwe ngokwemigangatho ye-AWWA C207 Class B. Ezi valve zinobukhulu obuyi-DN1000 (40 intshi) kunye noxinzelelo olulinganisiweyo lwe-150 psi (PN10). Umzimba wevalvu wenziwe ngentsimbi ethambileyo, kwaye uyilo lulandela ulungiselelo loqhagamshelo oluphindwe kabini lwe-bolting ngqo kwi-AWWA-pattern pipework.

Olu thutho lubonisa iodolo enkulu eyenziwe ngumzi-mveliso wethu weevalvu zeebhabhathane ezijijekileyo ezimbini kwaye lubonisa amandla ethu okusingatha iiprojekthi ezinkulu nezineenkcukacha eziphezulu ngexesha elifanelekileyo.

Iinkcukacha zobugcisa

Idiski kunye nesiqu zenziwe nge-duplex stainless steel grade 2507 (UNS S32750), ekhethwe ngenxa yokuxhathisa kwayo okubalaseleyo kwi-pitting, cravice corrosion, kunye ne-chloride stress corrosion cracking. Isihlalo sisebenzisa i-EPDM resilient liner ukuqinisekisa ukuvalwa okuqinileyo kwe-bubble kwi-full pressure rating. Ivalvu nganye ine-manual gearbox operator enobungakanani be-DN1000 bore.

Inkqubo yokugquma yangaphandle ihambelana ne-ISO 12944 Classification CX-H, udidi oluphezulu lokuqina oluchazwe kwiindawo zoshishino nezingaphandle kolwandle ezingcolisayo kakhulu. Olu lwazi lwepeyinti luqinisekisa ubomi obude benkonzo apho ukugquma okuqhelekileyo kungaphumeleli ngaphambi kwexesha ngenxa yobushushu, ukufuma, kunye nokuvezwa ziikhemikhali.

Isicelo kunye nokuHanjiswa

Ezi yunithi zevalvu zebhabhathane ezine-flange ephezulu ezisebenza kabini zenzelwe iprojekthi yenqaba yokupholisa eBukumkanini baseSaudi Arabia. Iivalvu zenqaba yokupholisa ezisebenza kummandla weGulf ziphantsi kobushushu obuphezulu, umswakama ophezulu, kunye neekhemikhali zamanzi ezinamandla, okwenza indibaniselwano ye-duplex 2507 internal kunye ne-ISO 12944 CX-H coating ibe yeyona nto ibalulekileyo kwixesha elide lempahla. Uvavanyo loxinzelelo lwe-AWWA C207 Class B luhambelana neesekethe zokujikeleza kwamanzi amakhulu eziqhelekileyo kwiinkqubo zokupholisa zoshishino kulo mmandla.

INortech ngumvelisi weevalvu zeebhabhathane osele ekhulile onamava okuthumela kwamanye amazwe kulo lonke elaseMbindi Mpuma, ebonelela ngeevalvu ezinkulu ze-AWWA-standard kwiinkonzo zamanzi, ukususa ityuwa, kunye nokusetyenziswa kokupholisa kwimizi-mveliso.
