Kubalawuli bokuthenga, abaphathi beenkonzo zehlabathi, kunye neenjineli ze-EPC, ukukhethwa komgangatho wezoshishinoumboneleli wevalvu yebholaayisosigqibo silula. Xa iiprojekthi zemibhobho zifuna ukuthembeka ngokupheleleyo koomatshini phantsi kweemeko zenkonzo ezixinzelelweyo okanye ezirhabaxa, zisebenzisana ngokuthe ngqo nomntu ofanelekileyo, oqinisekisiweyo yi-APIumzi-mveliso wevalvu yebholaiba licebo elibalulekileyo lokunciphisa umngcipheko. Ukubandakanyeka ngqo kwifektri kunciphisa iindleko zobunini (i-TCO), kuqinisekisa ukuba izinto ziyabonakala, kwaye kukhusela ukuhanjiswa kweprojekthi ngexesha elifanelekileyo.
INKAMPANI YEVALVE YE-NSW (nswvalve.com), umenzi weevalvu zebhola ophambili onekomkhulu eTshayina, unika umbono wangaphakathi kwiziseko zobugcisa, iinkqubo zokuvavanya, kunye nemigangatho yokuvelisa eyahlula umthengisi wevalvu yebhola okumgangatho ophezulu waseTshayina. Ngamava angaphezu kweminyaka engama-20 kushishino kunye nesakhiwo sokuvelisa esingama-20,000-square-meter, i-NSW ifumene udumo kwiinkampani ezinkulu zoshishino kuquka iPetroChina kunye neSinopec. Ukwanda kwenkampani kwimarike yaseYurophu ngesiseko sokuvelisa sase-Itali esasekwa ngo-2015 kubonisa ngakumbi ukuzinikela kwayo ekukhonzeni amashishini ehlabathi e-oyile, igesi kunye nenkqubo yeekhemikhali.
011. Ukulandelelana kunye noLawulo loMgangatho weZinto kwiNqanaba leFoundry
Ukunyaniseka kwesakhiwo sayo nayiphi naukudada or ivalvu yebhola efakwe kwi-trunnionImiselwa kudala ngaphambi kokuba kuqalwe ukwenziwa kwemishini—iqala kwindawo yokwenziwa kwesinyithi. Izinto ezisetyenziswa ekubunjweni ezingasemgangathweni zivelisa ukuvuleka kwangaphakathi, ukufakwa kwesanti, kunye nokuqhekeka okuncinci okunokubangela ukubhobozwa eludongeni ngaphambi kwexesha phantsi koxinzelelo.
Umzi-mveliso weevalvu zebhola okumgangatho wehlabathi unyanzelisa iNkqubo yoQinisekiso lweZinto olungenako ukuyekelela:
022. Amandla oMatshini aPhambili: Ukuqhuba ngokuLungileyo
Ukufikelela kumazinga okuvuza okungavuziyo—nokuba kukwimigangatho ye-API 598 okanye ye-ISO 5208 Rate A—kufuna ukuba umenzi weevalvu zebhola atshintshe iilathes ezidala ezenziwe ngesandla ngoomatshini abaphambili nabachanekileyo abazenzekelayo. Ukuqokelelana kokunyamezelana phakathi kwento yokuvala ibhola, iiringi zokugcina isihlalo, kunye nokulungelelaniswa kwesiqu sento yeyona nto iphambili ye-torque ephezulu yokusebenza kunye nokuguquguquka kwesihlalo kwindawo ethile.
Izakhiwo eziphambili zokuvelisa ivalvu yebhola eTshayina zisebenzisa iziko zoomatshini be-CNC ezine-axis ezininzi ukuze zigqibezele ukubopha umzimba, ukugqiba ubuso obupheleleyo, kunye nokusika intambo kwiseti enye yokulungisa. Le ndlela isusa iimpazamo ze-coaxiality ezivezwa ziinkqubo ezininzi zokubopha, nto leyo evumela ukuba impazamo ye-sphericity ilawulwe ngokungqongqo ngaphakathi kwee-microns ezi-5. Isiphumo sokwandiswa kakhulu kobomi bokusebenza kuzo zombini uyilo lweevalvu ezithambileyo nezine-metal.

(Imifanekiso enesisombululo esiphezulu yeeseli zoomatshini be-CNC zaseNSW ziyafumaneka kwiwebhusayithi esemthethweni yenkampani.)
033. Imigangatho yoBunjineli obuBalulekileyo kunye nokuThotyelwa kweMithetho
Xa ufaka uluhlu olufutshane kumthengisi weevalvu zebhola yezimboni, ukuthotyelwa kwemithetho kusebenza njengomlindi wesango ongenakuphikiswana. Umzi-mveliso ofanelekileyo kufuneka ube neziqinisekiso ezisebenzayo nezingqinisisekayo ezibonakalayo kwiirejista zobunjineli zehlabathi.
| Umgangatho wokufumana ulwazi | Ububanzi boLawulo kunye nokuGxila | Isenzo sokuqinisekisa ukufumaneka kwempahla |
|---|---|---|
| I-API Spec 6D | Iinkcukacha zeeValve zePipeline kunye neePiping | Ifuna ubukhulu bodonga obuqinileyo, ubukhulu bobuso nobuso, kunye nobuchule bokubethelela kabini kunye nokopha (DBB). |
| I-ISO 9001:2015 | Inkqubo yoLawulo loMgangatho (i-QMS) | Iqinisekisa ukuhambelana kwenkqubo, amanyathelo okulungisa, kunye noxanduva lwekhonkco lokubonelela ngeenkonzo kulo lonke icandelo lomzi-mveliso. |
| I-API 607 / I-API 6FA | Iinkcukacha zoVavanyo loMlilo lweZitulo eziThambileyo/zeSinyithi | Iqinisekisa ukuba imida yoxinzelelo iyagcinwa kwaye itywinwe kabini phantsi komlilo ogcweleyo we-hydrocarbon (1,400°F ukuya kwi-1,800°F). |
| I-API 641 / ISO 15848-1 | Ukuthobela uKhupho oluKhuphayo oluBalekileyo | Iqinisekisa ukuthembeka kokupakisha isiqu ukuthintela ukuvuza kwe-hazardous volatile organic compound (VOC) (<100 ppmv). |
Ngokuhlanganisa imveliso ngaphakathi kwifektri edibeneyo enelayisenisi ye-API 6D, iinjineli zifumana isiqinisekiso sokuba iimveliso ezihanjiswayo ziya kuhlanganiswa ngokungenamthungo nakweyiphi na indlela yokubeka imibhobho ye-ASME B16.5 okanye ye-ASME B16.47 ngaphandle kokufuna uhlengahlengiso lwentsimi.
044. Uvavanyo loxinzelelo, uhlolo, kunye novavanyo lokwamkelwa kwefektri (i-FAT)
Ivalvu nganye ephuma kwivalvu yebhola ephezulu yesityalo saseTshayina kufuneka ivavanywe uxinzelelo ngokuhambelana ngokungqongqo nemigaqo ye-API 598 okanye ye-API 6D. Umenzi ofanelekileyo ubonelela ngeZatifikethi zoVavanyo ezibhalwe phantsi ngokupheleleyo, ezinokulandeleka (EN 10204 Uhlobo 3.1) kwiyunithi nganye enenombolo ye-serial.
Ulandelelwano loVavanyo loKwamkelwa kweFactory (FAT) ludla ngokuquka:
Ukusebenzisana ne-NSW: Umthombo Wokuthenga Othe Ngqo Ovela Kwifektri
Ukukhethwa komenzi weevalvu zebhola ezifanelekileyo kuthetha ngokuthe ngqo kukhuseleko lwemibhobho yexesha elide kunye namaxesha eprojekthi aqikelelweyo. Ngokususa iinkampani zorhwebo eziphakathi kunye nokuthenga ngqo kwifektri yeevalvu zebhola esele imiselwe, abaqhubi behlabathi bafumana inkxaso yobunjineli ngqo, ulungelelwaniso lwe-alloy olunokwenziwa ngokwezifiso ngokupheleleyo, kunye nokucaca kwekhonkco lokubonelela ngezixhobo.
INKAMPANI YE-NSW VALVE idibanisa ukusebenza kakuhle kwemveliso yaseTshayina ekumgangatho wehlabathi kunye nolawulo oluqinileyo lomgangatho olufunwa ziinkqubo zeoyile, igesi kunye neekhemikhali zehlabathi. Ngeworkshop engama-20,000-square-meter, amava oyilo kunye nokuthumela ngaphandle amashumi amabini eminyaka, kunye nomgangatho wemveliso waseYurophu owasekwa ukusukela ngo-2015, i-NSW ibonelela ngeevalvu zebhola zoshishino—kubandakanya ulungelelwaniso oluhambayo kunye nolufakwe kwi-trunnion kwintsimbi yekhabhoni, intsimbi eyenziweyo, kunye nentsimbi engagqwaliyo—ezihlangabezana neemfuno ezifunwa kakhulu ngamazwe ngamazwe.
Nxibelelana neqela lobunjineli le-NSW namhlanje ukuze uhlole amaphepha edatha yeprojekthi yakho okanye ucele uphicotho oluthe ngqo lokuhlolwa kwefektri.
