ʻO nā ʻano hana hana no nā flanges kila kila
He mea koʻikoʻi ka flange kila kila no ka hoʻohui ʻana i nā paipu a me nā mea hana. Loaʻa iā ia nā hiʻohiʻona o ka pale wela kiʻekiʻe, ke kūpaʻa corrosion a me ka sila maikaʻi. Hoʻokaʻawale ʻia nā kaʻina hana flange stainless steel maʻamau i ʻehā ʻano: forging, hoʻolei ʻana, ʻokiʻoki, a me ka ʻōwili.
(1) Hoolei i ke kila kuhilihi
ʻO ke kaʻina hana o ka hoʻoheheʻe ʻana i ke kila hoʻoheheʻe ʻia i loko o ka mold e hoʻolei i nā flanges stainless steel ua kapa ʻia ke ʻano hoʻolei. ʻO nā mea maikaʻi: ʻo ke ʻano kūpono a me ka nui o ka blank, ka liʻiliʻi o ka hoʻoili ʻana, ke kumu kūʻai haʻahaʻa, a hiki ke hoʻoponopono ʻia ka ʻōpala e like me nā pono o ka mea kūʻai aku e hana i nā ʻano paʻakikī. Nā pōʻino: ʻO nā hemahema o ka hoʻolei ʻana (pores, māwae, inclusions), maikaʻi ʻole streamlined i loko o ka hoʻoheheʻe ʻana, maikaʻi ʻole ka ʻoki a me ka ikaika tensile. ʻOiaʻiʻo, aia nā kaʻina hana flange kila kila kiʻekiʻe e hiki ke hōʻemi i nā hemahema. No ka laʻana, ʻo nā flanges kuhili ʻole centrifugal kekahi ʻano o nā flanges kila kuhili ʻole. ʻO ke ala centrifugal kahi ala hoʻolei pololei no ka hana ʻana i nā flanges kila kila. ʻOi aku ka maikaʻi o nā flanges stainless steel i hoʻolei ʻia ma kēia ʻano ma mua o ka hoʻomākaukau ʻana i ke one maʻamau, ʻoi aku ka maikaʻi o ka maikaʻi, a ʻoi aku ka liʻiliʻi o nā pilikia e like me nā pores, nā māwae, a me ka trachoma.ʻO kēia ka wehewehe kikoʻī o ka hoʻolei centrifugal o nā flanges kila kila.
(2) Hoʻopaʻa ʻia ke kila kila
He ha'aha'a loa ka ma'i kalapona ha'aha'a ma mua o nā lepa kila kuhili'ole i ho'olei 'ia a 'a'ole hiki i ka pala. Loaʻa i nā forgings nā kahawai maikaʻi a me kahi ʻano paʻa. ʻOi aku ka maikaʻi o ko lākou mau ʻano mīkini ma mua o nā flanges kila kuhili ʻole a hiki iā lākou ke pale aku i nā ikaika ʻoi aʻe a me nā haʻalulu. Hoʻonui.
Hoʻopili ʻia a hoʻopaʻa ʻia nā flanges kila kuhili ʻole maʻamau.
ʻO ka flange forged he flange i hana ʻia e ka hana wela o nā mea metala a laila hahau. ʻO ka hiʻohiʻona nui o kēia kaʻina hana, ʻo ia ka hoʻohana ʻana i ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe e hoʻololi mālie i ka mea metala i mea e hoʻomaikaʻi ʻia ai kona ʻano a me kāna hana.
ʻO ka ʻokoʻa ma waena o ka flange forged a me ka flange forged ʻo ia ka hoʻohana ʻana i ka hana mechanical e hoʻoheheʻe i nā mea metala, kahi kaʻina hana metala e like me ka flange forged. Pili kēia kaʻina hana i ka hoʻopololei ʻana ma mua o ka hana lima.
ʻO kēia ka wehewehe kikoʻī o nā flanges kila kuhili ʻole forged a me nā flanges stainless steel forged.
(3) ʻOki ʻokiʻoki i ke kila kila
E ʻoki pololei i ke anawaena o loko a me waho a me nā diski mānoanoa o ka flange ma ka pā kila kila, a laila e hana i nā puka kī a me nā laina wai. ʻAʻole ʻoi aku ka nui o nā flanges stainless steel i ʻoki ʻia a hana maʻamau ma mua o DN150. Inā ʻoi aku ka nui ma mua o DN150, e piʻi nui ke kumukūʻai.
(4) Ua ʻōwili ʻia ke kila kila kila
ʻO ke kaʻina hana o ka ʻoki ʻana i nā papa waena kila kila a i ʻōwili ʻia i loko o nā pōʻai i hoʻohana nui ʻia i ka hana ʻana i kekahi mau flanges kila kila nui. Ma hope o ka holo pono ʻana, wili ʻia, a laila pālahalaha ʻia, a laila hana ʻia ka wai a me nā lua bolt. No ka mea ʻo ka mea maka he pā waena, ʻoi aku ka maikaʻi. ʻO ke kaʻina hana kuʻi ʻana ma ka ʻaoʻao o ka flange i ʻōwili ʻia he mea nui ia, a koi ʻia ka X-ray a i ʻole ke kiʻi ʻoniʻoni kani ultrasonic.
