Ke ʻimi nei i nā ʻokoʻa ma waena o nā flanges aluminika a me nā flanges kila kalapona

ʻO ka flange alumini a me ka flange kalapona he ʻelua mau mea like ʻole o nā flanges, aia kekahi mau ʻokoʻa i ka hana, ka hoʻohana ʻana, a me kekahi mau waiwai kino a me kemika. Eia nā ʻokoʻa nui ma waena o nā flanges alumini a me nā flanges kila kalapona:

1. Material:

Aluminum flange: hana maʻamau i ka alumini alumini, he māmā, ikaika kiʻekiʻe, conductivity maikaʻi, a me kekahi kūʻē corrosion. He kūpono nā flanges alumini no nā noi ʻaʻole pono ke kiʻekiʻe kiʻekiʻe, ke kiʻekiʻe kiʻekiʻe, a me ke kūpaʻa corrosion kiʻekiʻe.
ʻO ke kila kila kalapona: Hana ʻia me ke kila kalapona, maʻamau ʻo ASTM A105 a i ʻole ASTM A350 LF2. He kiʻekiʻe ka wela a me ke kūpaʻa ʻana o nā flanges carbon steel, e kūpono ana iā lākou no kahi ākea ākea o nā noi ʻoihana, me nā ʻenehana kiʻekiʻe a me ke kaomi kiʻekiʻe.

2. Ka mahana a me ke kaomi pale hana:

Aluminum flange: He haʻahaʻa haʻahaʻa ka pale ʻana o ka alumini i ka mahana a me ke kaomi a ʻaʻole kūpono ia no nā ʻōnaehana pipeline kiʻekiʻe a me ke kiʻekiʻe.
Flange kila kalapona: He kūpono ke kalapona kila no nā wahi hana me ke kiʻekiʻe o ka mahana a me ke kaomi a ʻoi aku ka maikaʻi o ka mahana a me ka hoʻokō ʻana i ka paʻakikī.

3. Ke kumu:

Aluminum flange: hoʻohana nui ʻia i kekahi mau ʻōnaehana pipeline māmā, ʻōnaehana mana, a me nā noi e pono ai ka conductivity maikaʻi a me nā ʻano māmā.
Carbon steel flange: hoʻohana nui ʻia i nā ʻōnaehana pipeline ʻoihana, me ka petroleum, kemika, ka mana a me nā māla ʻē aʻe, kūpono no nā noi ma lalo o nā ʻano wela a me nā kūlana paʻi.

4. Conductivity:

Aluminum flange: ʻO ka alumini kahi mea conductive maikaʻi, no laila ua kūpono nā flanges alumini no kekahi mau kūlana e pono ai ka conductivity, e like me nā ʻōnaehana mana.
ʻO ka flange kila kalapona: He maikaʻi ʻole ke kalapona kalapona, no laila ʻaʻole ia ke koho i makemake ʻia i nā noi e koi ana i ka conductivity maikaʻi loa.

5. Koina:

Aluminum flange: He mea maʻamau ke kumukūʻai no ka mea ʻoi aku ka kiʻekiʻe o ke kumukūʻai hana o ka alumini alumini.
ʻO nā flanges kila kalapona: ʻO ka mea maʻamau, ʻoi aku ka haʻahaʻa o ke kumukūʻai hana o nā flanges carbon steel, no laila e ʻoi aku ka hoʻokūkū ma kekahi mau papahana koʻikoʻi koʻikoʻi.

Ke koho ʻana e hoʻohana i nā flanges alumini a i ʻole carbon steel, pono e noʻonoʻo piha i nā koi ʻenehana kikoʻī, nā kūlana kūlohelohe, a me nā ʻano hana o ka flange.
