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

ʻO ke ʻano o W ke kākau, hoʻolei;

C-KILA KALAPONA ke hōʻike nei ke kila kalapona, ʻo A, b, a me C i ka waiwai ikaika o ke ʻano kila mai ka haʻahaʻa a i ke kiʻekiʻe.

Hōʻike ʻo WCA, WCB, WCC i ke kila kalapona, nona ka hana kuʻi maikaʻi a me ka ikaika mechanical. Hōʻike ʻo ABC i ka pae ikaika, WCB i hoʻohana pinepine ʻia. ʻO ka mea paipu e pili ana i ka WCB ʻo A106B, a ʻo ka mea hana forging e pili ana ʻo A105. Kūpono no nā valves ma lalo o ka mahana a me ke kaomi maʻamau.

ʻO WC6 ka hoʻoheheʻe ʻana o ke kila alloy. Loaʻa iā ia ke kūpaʻa wela kiʻekiʻe a me nā waiwai antioxidant a kūpono no nā valves ma lalo o ke kūlana wela kiʻekiʻe a me ke kaomi kiʻekiʻe.

ʻO ka mea pipeline e pili ana ma kahi o A355 P11, a ʻo ka ʻāpana forging ʻo A182 F11;

Eia kekahi, aia ʻo WC9, ke kila metala wela kiʻekiʻe, e pili ana i kahi o A355 P22, a pono e kūlike ke kālai ʻana me A182 F22.

He ikaika a paʻakikī hoʻi ka hoʻoheheʻe WC i hoʻopaʻa ʻia. Kūpono no nā noi ʻoihana maʻamau.

ʻO ke kila kalapona haʻahaʻa wela he haʻahaʻa kona paʻakikī a me ke kūpaʻa i ka pala. He kūpono ia no nā noi wela haʻahaʻa loa, e like me ke kinoea kūlohelohe LPG (LNG).

Hoʻopuka ʻo Zfa Valves i nā kiwikā pepeke WCB maʻamau no nā mea kūʻai aku ma ka honua holoʻokoʻa me ka mahana maʻamau, a hiki iā mākou ke hana i nā kiwikā pepeke LCC no nā mea kūʻai aku mai ʻEulopa ʻĀkau e like me Rusia, Finland etc.

ʻo WCB ma lunaKiwikā pulelehua wafer Kinaa me LCCPulelehua ʻūlū Kinakiwikā.

ʻO nā hoʻoheheʻe kila kalapona a me nā mea i hoʻoheheʻe ʻia i hoʻohana pinepine ʻia i nā kiwikā

Nā papa mea kila hoʻolei haʻahaʻa haʻahaʻa a me ka mahana kūpono

Nā papa hoʻohālikelike no ka hoʻoheheʻe ʻana a me ka hoʻolei ʻana i nā mea ASTM i hoʻohana pinepine ʻia i nā valves（ASME B16.5）

Nānā: 1) ʻO ka hoʻonohonoho ʻana o nā mea o ke kino o ka valve i hoʻoheheʻe ʻia he paʻa loa, ʻaʻole maʻalahi ke loaʻa nā hemahema, ʻaʻole i kaupalena ʻia nā ana kūkulu, hana pono ke kaomi, hoʻohana nui ʻia no ke kaomi kiʻekiʻe, nā kūlana oxygen, ke anawaena liʻiliʻi a i ʻole nā ​​​​pūʻulu liʻiliʻi ʻē aʻe o nā valves ma ke koho ʻana o ka forging no ka mahana kiʻekiʻe, ke kaomi kiʻekiʻe a i ʻole ka mahana haʻahaʻa a i ʻole nā ​​​​​​mea hana kūikawā; ʻO ka hoʻolei ʻana maʻamau e pili wale i ka medium a me ke kaomi haʻahaʻa, a hoʻohana ʻia no ka hoʻoheheʻe ʻana i nā valves ma ka hana nui.

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