Nā paipu i hoʻokaʻawale ʻia

ʻO ka paipu hoʻokaʻawale ʻia he ʻōnaehana paipu me ka insulation thermal. ʻO kāna hana nui ka hōʻemi ʻana i ka nalowale wela i ka wā e lawe ʻia ai nā mea pāpaho (e like me ka wai wela, ka mahu, a me ka ʻaila wela) i loko o ka paipu me ka pale ʻana i ka paipu mai nā mana o ke kaiapuni. Hoʻohana nui ʻia ia i ka hoʻomehana hale, ka hoʻomehana ʻāpana, nā petrochemicals, ka ʻenekinia kūlanakauhale, a me nā ʻoihana ʻē aʻe.

1. ʻAno Kūkulu

ʻO ka paipu insulated he ʻano hui pū ʻia he nui nā papa i haku ʻia me ʻekolu mau ʻāpana nui:

• Paipu Kila Hana: ʻO ka papa ʻiʻo o loko, kuleana no ka lawe ʻana i nā mea pāpaho. ʻO nā mea hana maʻamau e komo pū me ke kila humuhumu ʻole, ke kila galvanized, a i ʻole nā ​​paipu plastik, a pono e kūpaʻa i ke kaomi a me ka pala.

• Papa Hoʻokaʻawale: ʻO ka papa waena koʻikoʻi, kuleana no ka hoʻokaʻawale wela. ʻO nā mea maʻamau e komo pū me ka huʻa polyurethane, ka huluhulu pōhaku, ka huluhulu aniani, a me ka polyethylene. ʻO ka huʻa polyurethane ke koho nui i kēia manawa ma muli o kona conductivity wela haʻahaʻa a me ka hana hoʻokaʻawale maikaʻi loa.

• ʻUpena Waho: Mālama ka papa pale waho i ka papa insulation mai ka makū, ka ʻelemakule, a me ka pōʻino mechanical. ʻO nā mea hana maʻamau e komo pū me ka polyethylene kiʻekiʻe-density (HDPE), fiberglass, a i ʻole kahi uhi anti-corrosion.

II. Nā ʻAno Nui a me nā ʻAno

Ma muli o ka mea insulation a me ke ʻano o ka noi, ʻo nā ʻano maʻamau a me nā hiʻohiʻona penei:

• Paipu Hoʻopaʻa ʻia me ka Polyurethane: ʻO ke alakaʻi wela ≤ 0.024 W/(m·K), ka pono o ka insulation kiʻekiʻe, ke kūpaʻa haʻahaʻa o ka mahana, a me ke kūpaʻa ʻana i ka wā ʻelemakule. Kūpono no nā paipu wai wela a me ka mahu me nā mahana ma waena o -50°C a me 120°C, ʻo ia ke koho makemake ʻia no nā ʻōnaehana hoʻomehana waena a me ka hoʻomehana papahele.

• Paipu Hoʻopaʻa ʻia me ka Rockwool: Ke kūpaʻa wela kiʻekiʻe (a hiki i ka 600°C) a me ka helu ahi kiʻekiʻe (Class A ʻaʻole hiki ke puhi ʻia), akā me ka omo wai kiʻekiʻe, pono ia i ka pale ʻana i ka makū. Hoʻohana nui ʻia ia no nā paipu wela kiʻekiʻe ʻoihana (e like me nā paipu mahu paila).

• Paipu Hoʻopaʻa ʻia me ka Huluhulu Aniani: Māmā, me ka pale leo maikaʻi loa, a me ka pae kūpaʻa mahana o -120°C a i 400°C, kūpono ia no nā paipu wela haʻahaʻa (e like me nā paipu refrigerant ea hoʻoluʻu) a no ka pale ʻana i nā paipu i loko o nā hale kīwila.

III. Nā Pōmaikaʻi Koʻikoʻi

1. Ka Mālama Ikehu a me ka Hoʻemi ʻana i ka Hoʻohana ʻana: Hoʻemi i ka pohō wela i loko o ka waena, e hoʻohaʻahaʻa ana i ka hoʻohana ʻana i ka ikehu i ka hoʻomehana ʻana, ka hana ʻoihana, a me nā hiʻohiʻona ʻē aʻe. Hiki i ka hoʻohana lōʻihi ke hōʻemi nui i nā kumukūʻai hana.

2. Ka Palekana o ka Paipu: Mālama ka ʻūpā o waho i ka wai, ka pala o ka lepo, a me ka hopena mechanical, e hoʻolōʻihi ana i ke ola lawelawe o ka paipu a e hōʻemi ana i ka pinepine o ka mālama ʻana.

3. Hana Paipu Paʻa: Mālama i ka mahana waena paʻa e pale aku i nā loli o ka mahana mai ka hoʻopilikia ʻana i ka hana (e laʻa, mālama i ka mahana o loko no nā paipu hoʻomehana a me ka hōʻoia ʻana i ke kūpaʻa o ke kaʻina hana no nā paipu ʻoihana).

4. Ka Hoʻouka Kūpono: Ua hana mua ʻia kekahi mau paipu insulated, e koi ana i ka pilina ma kahi a me ke kau ʻana, e hoʻopōkole ana i ka wā kūkulu a e hōʻemi ana i ka paʻakikī.

IV. Nā Noi Pili

• Kūlanakauhale: Nā pūnaewele hoʻomehana kikowaena kūlanakauhale a me nā paipu wai piula (e pale aku i ka hau ʻana i ka hoʻoilo).

• Kūkulu ʻana: Nā paipu hoʻomehana papahele ma nā hale noho a me nā hale kalepa, a me nā paipu waena hoʻomehana a hoʻoluʻu no ka ea hoʻoluʻu waena.

• ʻOihana: Nā paipu ʻaila wela i nā ʻoihana ʻaila a me nā kemika, nā paipu mahu i nā hale hana mana, a me nā paipu waena cryogenic i nā logistics kaulahao anu.
