I-Carbon Steel ANSI Flange Globe valve

Singumenzi wamavalvu ochwepheshe ophethe izitifiketi ze-ISO, CE kanye ne-API. Sihlomisa imishini yokucubungula ephelele kanye nezindinganiso eziqinile zokuhlola inqubo egcwele ukuze ihambisane nemininingwane yezimboni ze-ANSI. Siphinde sithathe ama-oda enziwe ngokwezifiso e-OEM ne-ODM anezidingo zenani eziguqukayo zesivivinyo esincane namaphrojekthi amakhulu wobunjiniyela. Amavalvu ethu e-ANSI carbon steel globe athunyelwa ezimakethe emhlabeni wonke futhi azuza ukwethenjwa okuqinile kubathengi baphesheya.

Izimfanelo Ezibalulekile

Yiziphi izindinganiso ezibalulekile zalawa ma-valve?

Wonke ama-valve ethu alandela izindinganiso zaseMelika ze-ANSI. Izicaciso eziyinhloko zihlanganisa i-ASME B16.34 yokulinganisa izinga lokushisa kwe-valve, i-ASME B16.5 yobukhulu be-flange, i-API 598 yokuhlola ukuvuza nokucindezela. Impahla yomzimba i-WCB ithobelana nezinga le-ASTM A216 ukuze ilingane nezimo zokusebenza ezishisa kakhulu.

Yiziphi izilinganiso zengcindezi evamile (Amakilasi)?

Ikilasi 150, Ikilasi 300 kanye Ikilasi 600 amamaki ethu avamile. I-Class 150 ilingana nokushisisa okujwayelekile namapayipi amanzi. I-Class 300 ne-Class 600 zihambisana nomusi womfutho ophezulu, uwoyela oshisayo namapayipi amakhemikhali anemingcele yokusebenza eqinile. Amakilasi aphezulu angokwezifiso angenziwa ngesicelo sakho.

Yiziphi izinhlelo zokusebenza ezingcono kakhulu kuzo?

Zilingana neziteshi zikagesi ezishisayo, izindawo zokuhluza, izinhlelo zokufudumeza kanye namapayipi okuhambisa uwoyela oshisayo. Lezi zingosi zivame ukudinga ukulungisa isivinini sokugeleza nokucindezela njalo, okufana nesici esinyakazayo samavalvu eglobhu e-ANSI. Baphinde basebenze kahle emigqeni yokulethwa kwesitimu kanye nowoyela oshisayo.

Ingabe zingasetshenziswa kukho kokubili ukulawulwa kokugeleza nokuvala?

Yebo, lokhu kuyinzuzo yabo enkulu ngaphezu kwama-valve esango. Ungakwazi ukujikisa isondo lesandla ukuze ulungise ukugeleza okumaphakathi nengcindezi ngokushelela ukuze ulawule kahle. Uma ivaliwe ngokuphelele, indawo yokuvala yensimbi inikeza ukuvala okuqinile ukuze kunqamule uketshezi ngokuphelele. Azinconywa ukuthi zihlale zivulekile ukuze zisebenze isikhathi eside noma kunjalo.

Yiziphi izinhlobo ze-flange ezijwayelekile ezitholakalayo?

I-Raised Face (RF) flanges iza njengokucushwa kwethu okujwayelekile kwama-oda amaningi ajwayelekile. Lo mklamo ulingana namapayipi avamile aphakathi nendawo naphansi, kulula ukufakwa nokumataniswa kwe-gasket, asetshenziswa kakhulu kumavalvu e-Class 150 kanye ne-Class 300.

Ngezinga lokushisa eliphezulu eliqinile, izimo zokusebenza ezinengcindezi ephezulu kusukela ku-Class 600, sinikeza ama-flange ahlangene eringi ye-RTJ njengenye inketho. Njengoba ifakwe ama-metal ring gaskets, lawa ma-flange avala kangcono kakhulu futhi agweme ukuvuza uketshezi ngisho nangaphansi kokushisa nokucindezela okukhulu.

Uma iphrojekthi yakho inezidingo ezihlukile zokufanisa amapayipi, singaphinda sikhiqize ezinye izitayela ze-ANSI flange ezihlanganisa ubuso obuyisicaba be-FF, ukuze kulingane ama-flange akhona afakwe kumapayipi akho.
