Inā kānalua ʻoe i ke koho ʻana i nā kiwi puka kila hoʻoheheʻe ʻia a i ʻole nā ​​kīwī puka kila (WCB), e ʻoluʻolu e nānā i ka hale hana kīwī zfa e hoʻolauna i nā ʻokoʻa nui ma waena o lākou.

1. ʻO ka forging a me ka hoʻolei ʻana he ʻelua ʻano hana hana like ʻole.

Ka hoʻolei ʻana: Hoʻomaʻamaʻa ʻia ka metala a hoʻoheheʻe ʻia a laila ninini ʻia i loko o kahi ʻeleʻele a i ʻole ka lepo.Ma hope o ka hoʻoluʻu ʻana, paʻa ia i mea.Hoʻopuka maʻalahi nā puka ea ma waena o ka huahana.
Forging: ʻO ka hoʻohana nui ʻana i nā ʻano hana e like me ka hammering i nā wela kiʻekiʻe e hana i ka metala i mea hana me ke ʻano a me ka nui i loko o kahi kūlana plastik, a hoʻololi i kona mau waiwai kino.

2. Nā ʻokoʻa o ka hana ma waena o nā ʻīpuka palaki a meNā ʻīpuka puka WCB

I ka wā forging, hoʻohana ʻia ka metala i ka deformation plastic, nona ka hopena o ka hoʻomaʻemaʻe ʻana i nā kīʻaha, no laila hoʻohana pinepine ʻia i ka hana ʻole o nā ʻāpana koʻikoʻi.Loaʻa i ka hoʻolei ʻana nā koi i nā mea e hana ʻia.ʻO ka maʻamau, ʻoi aku ka maikaʻi o ka hoʻolei ʻana i ka hao, aluminika, etc.ʻAʻole nui ka maikaʻi o ka hoʻolei ʻana, akā hiki iā ia ke hana i nā ʻāpana me nā ʻano paʻakikī, no laila hoʻohana pinepine ʻia i ka hana ʻole o nā ʻāpana kākoʻo ʻaʻole pono nā waiwai mechanical kiʻekiʻe.

2.1 Paʻi

Ma muli o nā ʻokoʻa o nā waiwai waiwai, hiki i nā kiwi kila i hoʻopaʻa ʻia ke kū i nā ikaika hopena nui, a ʻoi aku ka kiʻekiʻe o ko lākou plasticity, ka paʻakikī a me nā mea hana ʻē aʻe.Nā kīwī WCB.No laila, hiki ke hoʻohana ʻia i nā kūlana hana kiʻekiʻe.ʻO nā pae kaomi maʻamau i hoʻohana ʻia o nā kiwi kila forged: PN100;PN160;PN250;PN320;PN400, 1000LB~4500LB.ʻO nā puʻe inoa maʻamau i hoʻohana ʻia o nā kīwī WCB: PN16, PN25, PN40, 150LB~800LB.

2.2 Anawaena Nominal

No ka mea he kiʻekiʻe nā koi o ka hana forging i nā mold a me nā mea hana, ʻo ke anawaena o nā valve forged ma lalo o DN50.

2.3 Hiki ke kū i ka leakage

Hoʻoholo ʻia e ke kaʻina hana ponoʻī, hiki i ka hoʻolei ʻana ke hana i ka blowhole i ka wā o ka hana.No laila, ke hoʻohālikelike ʻia me ke kaʻina hana forging, ʻaʻole maikaʻi ka maikaʻi o ka pale ʻana i ka leakage o nā kiwi hoʻolei e like me ka maikaʻi o nā valve forged.
No laila, i loko o kekahi mau ʻoihana me nā koi pale leakage kiʻekiʻe, e like me ke kinoea, ke kinoea maoli, ka ʻaila, nā kemika a me nā ʻoihana ʻē aʻe, ua hoʻohana nui ʻia nā pahu kila forged.

2.4 Nānā

He maʻalahi ke hoʻomaopopo ʻana i nā kiwi WCB a me nā kiwi kila forged.ʻO ka maʻamau, he hiʻohiʻona kālā nā kīwī WCB, ʻoiai he ʻeleʻele nā ​​hiʻohiʻona kila forged.

3. Nā ʻokoʻa ma nā kahua noi

ʻO ke koho kikoʻī o nā kīwī WCB a me nā kiwi kila forged e pili ana i ka ʻenehana hana.ʻAʻole hiki ke hoʻohālikelike ʻia e pili ana i nā māla e hoʻohana ai i nā kiwi kila forged a me nā māla e hoʻohana ai i nā kiwi WCB.Pono e koho ʻia ma ke ʻano hana kūikawā.ʻO ka ʻōlelo maʻamau, ʻaʻole kūpaʻa ka waika WCB a me ka alkali a hiki ke hoʻohana wale ʻia ma nā pipeline maʻamau, ʻoiai nā kiwi kila forged hiki ke kū i ke kaomi kiʻekiʻe a hiki ke hoʻohana ʻia i kekahi mau hale me nā wela kiʻekiʻe, e like me nā mea kanu mana a me nā mea kanu kemika.Pāpā papa.

4. Kumukuai

ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o nā pahu kila forged ma mua o nā kīwī WCB.
