ʻO nā paipu kila i hoʻopaʻa ʻia he ʻōnaehana paipu hui e hoʻohui i nā hiki o ka lawe ʻana i ka pipeline me ka ʻenehana insulation kūpono. Hoʻohana nui ʻia lākou i ka petroleum, kemika, ka hoʻomehana ʻāina, ka refrigeration, a me nā ʻoihana insulation ʻoihana. Aia ko lākou waiwai nui i kā lākou hoʻolālā hoʻolālā kū hoʻokahi, e hōʻemi ana i ka nalowale o ka wela i ka wā e hoʻokō ai i nā koi ʻenehana e like me ke kūpaʻa corrosion a me ke kūpaʻa kaomi.
I. Nā Mea Hana Kumu o nā Paipu kila i hoʻopaʻa ʻia
ʻAʻole i hana ʻia nā paipu kila i hoʻopaʻa ʻia mai ka mea hoʻokahi akā aia he ʻekolu- ʻano ʻano: he paipu kila hana, kahi ʻāpana hoʻopololei, a me kahi pūpū pale waho. Hoʻokomo pū kekahi mau hoʻolālā i nā papa hana kōkua e like me nā laina leak alarm.
1. Paipu kila hana (Inner Pipe)
ʻO nā paipu kila hana ka mea lawe pololei o ka mea lawe ʻia (e like me ka wai wela, ka mahu, a i ʻole ka aila). Hana ʻia lākou me ka paipu kila ʻole, ka paipu wiliwili spiral, a i ʻole ka paipu wili wili pololei. Koho ʻia ka mea ma muli o nā hiʻohiʻona o ka waena, e like me ke kila kalapona, ke kila kila, a i ʻole ke kila kila. Pono ka paia o loko e ho'okō i nā koi 'ino a me ka pi'i -ki'eki'e, a'o ka paia o waho e ho'opa'a pa'a 'ia i ka papa insulation.
2. Layer Insulation (Layer Insulation Intermediate)
ʻO ka papa insulation ka papa ʻenehana koʻikoʻi o ka paipu kila insulated, ʻo kāna hana nui ka pale ʻana i ka hoʻoili wela. ʻO nā mea insulation maʻamau ka:
ʻO Polyurethane foam (PUF): Haʻahaʻa haʻahaʻa wela (ma kahi o 0.024 W/m·K), kiʻekiʻe pani ʻia -maʻiʻo pūnaewele, a me ka ikaika compressive kiʻekiʻe. ʻO ia ka mea ʻoi loa o ka hoʻomake ʻana i kēia manawa a ua hū ʻia ma - kahua a i hana mua ʻia paha i loko o nā hale hana.
Huluhulu pōhaku/hulu aniani: He kūpono no ka -kaiapuni kiʻekiʻe (e laʻa, ma luna o 500 degere ), akā he kiʻekiʻe kiʻekiʻe a me ka hygroscopicity ikaika.
Papahana huihue Airgel: He nanomaterial ultra -māmā hou me ka haʻahaʻa haʻahaʻa loa (<0.018 W/m·K), but it is more expensive and is primarily used in specialized, high-end projects.
Ua helu ʻia ka mānoanoa o ka papa insulation ma muli o ke ana wela, ka ʻokoʻa o ka mahana ambient, a me nā noʻonoʻo waiwai, maʻamau mai 30 a 150 mm.
3. Puʻu Pale
Mālama ka pūpū pale i ka papa insulation mai ka pōʻino mechanical, radiation UV, a me ka ʻino o ka lepo. Aia nā mea maʻamau:
Polyethylene kiʻekiʻe -kiʻekiʻe (HDPE): ʻAʻohe ʻino -kū a me ka wai ʻole, kūpono no ka hoʻokomo ʻana ma lalo o ka honua, i hana ʻia e ka welina hoʻoheheʻe wela.
Ke kila/aluminika galvanized: Hoʻohana ʻia no nā paipu ma luna o ke poʻo a i ʻole nā wahi wela -kiʻekiʻe, hāʻawi ia i ka ikaika mechanical kiʻekiʻe a hiki ke hoʻohui ʻia me ka uhi -corrosion e hoʻolōʻihi i kona ola lawelawe.
Fiberglass reinforced plastic (FRP): Hoʻohui i ka pale ʻana i ka corrosion me nā waiwai māmā, e kūpono ana ia no nā wahi ʻino loa e like me ka ʻoihana kemika.
II. Nā Kūlana Kokua a me nā Hoʻonui Hana
Hiki ke hoʻohui hou i kekahi ʻōnaehana paipu kila insulated kiʻekiʻe i kēia mau hale:
Leakage alarm wire: Hoʻokomo ʻia i loko o ka papa insulation, ʻimi koke i ka wahi hewa ma o ka hoʻololi ʻana i ka hōʻailona uila i ka wā e puka mai ai kahi leak i ka paipu kila hana, e hoʻonui ai i ka palekana.
Paʻa paʻa/kākoʻo apo: Hoʻohana ʻia no ka lōʻihi-kaomi pololei-pili i hoʻoemi ʻia e hōʻemi i ka pōʻino o ka hoʻonui ʻana i ka wela.
ʻO ka hoʻoheheʻe ʻana i ka ʻūhā (kahi hoʻolālā ʻokoʻa a kūikawā): ʻO kēia ka mea e hōʻemi hou ai i ka lawe ʻana i ka wela ma o ka hoʻoheheʻe ʻana, akā kiʻekiʻe loa ke kumukūʻai ʻenehana.
III. Nā Pono Kūleʻa o nā Paipu kila i hoʻopaʻa ʻia
Kiekie -Efficiency Insulation: ʻO ka multi-papa hana like synergistically, ka hopena i ka wela haʻahaʻa haʻahaʻa ma mua o ko nā paipu kila maʻamau, e hōʻemi ana i ka wela i ka 1/5 a i ka 1/10 o nā paipu kahiko.
Ola lōʻihi: ʻAʻole ʻānai ka ʻahu waho -a kū i ka hoʻohaʻahaʻa honua, me ke ola o ka hoʻolālā ʻana he 30 a 50 mau makahiki.
Hana maʻalahi: Hiki i nā paipu i hoʻolele ʻia i hoʻopaʻa ʻia ma mua o ka hana ʻana i ka hale hana maʻamau, e koi ana ma-hoʻomākaukau ʻana i ka paena, e hoʻopōkole loa i ka manawa hana.
Palekana Kaiapuni a me ka mālama ʻana i ka ikehu: E hōʻemi i ka pau ʻana o ka ikehu, e hoʻokō i nā koi ʻenehana ʻōmaʻomaʻo ma lalo o nā pahuhopu "kapona ʻelua".
Ka hopena
ʻO ka hoʻolālā hoʻolālā o nā paipu kila insulated e hoʻokomo i kahi hoʻohui hohonu o ka ʻepekema waiwai, thermodynamics, a me nā noi ʻenehana. Mai ka paipu kila hana i loko a i ka pahu pale o waho, ua hoʻopaneʻe ʻia kēlā me kēia papa no kāna hana kikoʻī, i ka hopena e hoʻokō i nā pahuhopu lehulehu o "ka lawe ʻana maikaʻi + ka -hoʻokolo lōʻihi + palekana hilinaʻi." Me ka hoʻomohala ʻana i nā mea hoʻolalelale hou (e like me nā aerogels a me ka nano -pale insulation), e hoʻomau ʻia ke ʻano o nā paipu kila insulated e lilo i ʻoi aku ka māmā a me ka naʻauao, e hoʻonui ana i ko lākou hiki ke hoʻohana i nā ʻāpana e kū mai ana e like me ka ikehu hou a me nā paipu moana hohonu.
