Pehea e koho ai i ka mea o WCB/LCB/LCC/WC6/WC no ka valve?

ʻO W ke kākau, hoʻolei;

C-CARBON STEEL ke kila kalapona, A, b, a me C hōʻike i ka waiwai ikaika o ke ʻano kila mai ka haʻahaʻa a i ke kiʻekiʻe.

ʻO WCA, WCB, WCC e hōʻike ana i ke kila kalapona, he maikaʻi ka hana kuʻi ʻana a me ka ikaika mechanical.Hōʻike ka ABC i ka pae ikaika, WCB maʻamau.ʻO ka mea paipu e pili ana i ka WCB he A106B, a ʻo A105 ka mea forging e pili ana.He kūpono no nā kiwi ma lalo o ka mahana a me ke kaomi maʻamau.

ʻO WC6 ka hoʻolei ʻana i ke kila kila.Loaʻa iā ia ke kūpaʻa kiʻekiʻe kiʻekiʻe a me nā waiwai antioxidant a kūpono i nā valve ma lalo o ke kiʻekiʻe kiʻekiʻe a me nā kūlana kiʻekiʻe.

ʻO ka mea pili i ka pipeline e pili ana iā A355 P11, a ʻo ka ʻāpana forging ʻo A182 F11;

Eia kekahi, aia ka WC9, ke kila kila kiʻekiʻe, e pili ana ma kahi o A355 P22, a ʻo ka hoʻopaʻa ʻana e kūpono me A182 F22.

Loaʻa ka ikaika kiʻekiʻe a me ka paʻakikī o ka hoʻolei ʻana o WC.He kūpono no nā ʻoihana hana maʻamau.

LCB/LCC (ASTM A352) ʻO ke kila kalapona haʻahaʻa haʻahaʻa haʻahaʻa ka paʻakikī a me ka pale ʻana i ka corrosion.He kūpono ia no ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, e like me ka LPG maoli kinoea (LNG).

Hoʻokumu ʻo Zfa Valves i nā kīwī lele WCB maʻamau no nā mea kūʻai aku ma ka honua holoʻokoʻa me ka mahana maʻamau, a hiki iā mākou ke hana i nā kīwaha butterfly LCC no nā mea kūʻai mai ʻĀkau o ʻEulopa e like me Russia, Finland etc.

ʻO ka hoʻolei ʻana i ke kila kalapona a me nā mea hana i hoʻohana mau ʻia i nā kiwi

Haʻahaʻa haʻahaʻa hoolei kila kila māka a me ka pili ana wela

ASTM mea forging a me ka hoʻolei ʻana i nā papa hoʻohālikelike i hoʻohana mau ʻia i nā kiwi (ASME B16.5)

'Ōlelo Aʻo: 1) paʻa paʻa, ʻaʻole maʻalahi ka loaʻa ʻana o nā hemahema, ʻaʻole i kau ʻia ka nui o ke kino i nā palena o ka mold, ka hana paʻa hilinaʻi, ka hapa nui i hoʻohana ʻia no ke kaomi kiʻekiʻe, nā kūlana oxygen, ka liʻiliʻi liʻiliʻi a i ʻole nā ​​​​hui liʻiliʻi ʻē aʻe o nā valves. ka hana ʻana i ka wela kiʻekiʻe, kiʻekiʻe a i ʻole ka haʻahaʻa haʻahaʻa a i ʻole ka media kūikawā ma lalo o ke koho o ka forging;Hoʻopili wale ʻia ka hoʻolei ʻana i ka medium a me ka haʻahaʻa haʻahaʻa, a hoʻohana ʻia no ka hoʻoheheʻe ʻia ʻana o nā kiwi ma ka hana nui.

(2) Material A351 CF3M a me A182 F316L ʻokoʻa: ʻo nā kūlana ʻelua e pili ana i nā mea he 316 stainless steel.Hōʻike ka CF3M i ka hoʻolei ʻana, hoʻohana mau ʻia e like me nā mea valve.ʻO A182 F316L ke code kila forging.ʻO ka ASTM A216 WCB ke hoʻolei ʻana, a ʻo kāna mau kala ʻana ʻo A105;ʻO ka hoʻolei ʻana o SS304 ʻo A351-CF8, a ʻo A182-F304 ka forgings.
