I-Carbon Steel yeSizwe yeGlobhu iValve

Singumenzi wevalvu oqeqeshiweyo obambe iziqinisekiso ze-ISO, i-CE kunye ne-API. Samkela imveliso esemgangathweni engqongqo kunye neenkqubo zokuhlola umgangatho opheleleyo ukuze siqinisekise ukuba zonke iivalvu zithobela iimfuno zomgangatho wesizwe. Siyakwazi ukwenza iivalve ngokwezicelo zakho ze-OEM kunye ne-ODM. Samkela iiodolo zovavanyo oluncinane kunye neeodolo ezinkulu zamaphulo okwakha ngaphandle kwemida engqongqo yesixa. Iivalvu zethu zelizwe ezisemgangathweni zekhabhoni zentsimbi zithunyelwa kumazwe amaninzi, kwaye abathengi bamashishini bahlala bethetha kakhulu ngabo.

Zeziphi izinto ezisetyenziselwa ukuvelisa iCarbon Steel National Standard Globe Valves?

Umzimba wevalvu uphoswe kwintsimbi yekhabhoni yeWCB. Inamandla olwakhiwo oluqinileyo kwaye inokusebenza ngokuthembekileyo phantsi kweemeko zemibhobho yobushushu obuphezulu. Idiskhi yevalvu kunye nesiqu sevalvu zenziwe ngentsimbi engatyiwayo ukunqanda ukurusa. Umphezulu woqhagamshelwano wokutywina udityaniswe nge-Stellite alloy; olu lwaleka lunzima luxhathisa ukunxiba, ukukhuhlwa kobushushu obuphezulu kunye nokhukuliseko olungephi oluvela kwimithombo yeendaba ehambayo. Iigaskithi kunye nokupakisha zisebenzisa izixhobo ezidibeneyo zegraphite ukugcina ukutywinwa okuqinileyo phantsi kobushushu.

Iimpawu eziphambili

Zeziphi iiklasi zoxinzelelo ezisemgangathweni ezixhaswa zezi zivalo zeglowubhu zomgangatho wesizwe?

Zonke iivalve zethu zihambelana nemigangatho ye-GB, kwaye amabakala ethu oxinzelelo oluqhelekileyo PN16, PN25, PN40 kunye ne-PN64. I-PN16 kunye ne-PN25 ihambelana nokufudumeza rhoqo kunye nemibhobho yamanzi. I-PN40 kunye ne-PN64 yenzelwe i-high-pressure steam kunye nemibhobho yeoli esetyenziswa kumandla kunye neefektri zekhemikhali. Ukuba iimeko zakho zokusebenza zidinga amanqanaba oxinzelelo olukhethekileyo, sinokukwenzela zona ngokwesiko.

Zeziphi iintlobo zemidiya yenkqubo ezinokuthi ezi zivalo zeglowubhu zentsimbi zekhabhoni ziziphathe ngokukhuselekileyo?

Zilungele ubushushu obuphezulu obugcwele umphunga, i-oyile yokuqhuba i-thermal, umoya oxinanisiweyo, amanzi okutya kwibhoyila kunye nolwelo olungathathi hlangothi kwimizi-mveliso. Zisebenza ngokuzinzileyo phantsi kobushushu obuphezulu bemeko apho iivalvu zokutywina ezithambileyo ziya kusilela. Azikhuthazwa kwi-asidi eyomeleleyo, i-alkali eyomeleleyo okanye i-high-chloride ulwelo oludlekayo ngaphandle konyango olongezelelweyo lwe-lining.

Ngawaphi amasimi asebenza rhoqo eCarbon Steel National Standard Globe Valves kwimibhobho yawo?

Zifakwe ngokubanzi kwizityalo zamandla obushushu, izikhululo zebhoyila ephakathi, iiworkshops zepetrochemical processing, iinkqubo zokufudumeza impahla kunye nemibhobho yamanzi ejikeleza kwimizi-mveliso. Ezi ndawo zihlala zifuna ukulungiswa rhoqo komthamo wokuhamba kunye noxinzelelo lwemibhobho, eyona nto iluncedo kwiivalvu zeglowubhu.

Ngowuphi umahluko ophambili okhoyo phakathi kweevalvu zeglowubhu kunye neevalvu zesango?

Kukho umsantsa ocacileyo wokusetyenziswa. Iivalvu zeglowubhu zenziwe ukulawula ukuhamba kunye nokulungelelanisa uxinzelelo, kwaye isakhiwo sazo sangaphakathi sinokumisa ulwelo olubuyela ngasemva. Nokuba zivuleke ngokupheleleyo, zisadala ukuxhathisa okuphakathi.

Iivalvu zesango zezokuvulwa ngokupheleleyo okanye ukuvala imibhobho kuphela, awukwazi ukuzisebenzisa ukulungisa amazinga okuhamba. Nje ukuba ivuleke ngokubanzi, akukho nakuphi na ukuxhathisa ulwelo okwenzekayo, kodwa abanako ukukuthintela ukubuya umva kolwelo okanye igesi.
