He aha ka mea ʻoi aku ka maikaʻi no nā paipu mahu?

Ua hala ka hoʻomaka ʻana o ka hoʻoilo, a ua emi mālie ka mahana, ʻoi aku hoʻi ma nā wahi ʻākau. He haʻahaʻa ka mahana i ka hoʻoilo, a ʻo ka mālama mau ʻana i ka mahana i ka wā o ka lawe ʻana i ka mahu ua lilo ia i pilikia no nā mea a pau. I kēia lā, e kamaʻilio ʻo Nobeth iā ʻoe e pili ana i ke koho ʻana i nā mea hoʻokaʻawale pipeline.

ʻOiai he nui nā mea insulation, ʻokoʻa nā mea hana like ʻole i ka noi. He mea kūikawā nā mea hoʻoheheʻe i hoʻohana ʻia i nā paipu mahu, akā he aha nā mea insulation i hoʻohana ʻia no nā paipu mahu? I ka manawa like Pono ʻoe e ʻike i ke ʻano o nā mea insulation no nā paipu mahu, i hiki iā ʻoe ke koho maikaʻi i kahi mea kiʻekiʻe.

He aha nā mea insulation i hoʻohana ʻia no nā paipu mahu?

1. E like me ka Paukū 7.9.3 o ka GB50019-2003 "Design Code for Heating, Ventilation and Air Conditioning", i ke koho ʻana i nā mea insulation no nā mea hana a me nā paipu, pono e hāʻawi ʻia i nā mea me ka conductivity thermal liʻiliʻi, ke kumu kūʻē nui o ka moisture. haʻahaʻa haʻahaʻa wai, haʻahaʻa haʻahaʻa, a me ka hoʻokele waiwai. Nā mea hana kiʻekiʻe; ʻO nā mea insulation he mea hiki ʻole ke puhi ʻia a i ʻole ke ahi-retardant mea; pono e helu a hoʻoholo ʻia ka mānoanoa o ka paipu insulation layer e like me ka mānoanoa o ka hoʻokele waiwai ma GB8175 "Alakaʻi no ka hoʻolālā ʻana i nā lako a me ka hoʻopili ʻana i ka paipu" i ka wā hoʻomehana.

2. Hoʻohana pinepine ʻia nā mea hoʻolalelale ʻana i ka cork, alumini silicate, polystyrene a me ka polyurethane. ʻO ka mea e hoʻohana ai e noʻonoʻo ʻia ma muli o ka paʻakikī o ka pipeline ʻōnaehana a me ke kumukūʻai o ka mea insulation. ʻO ka mea maʻamau, pono e like nā mea insulation i hoʻohana ʻia i loko o kahi ʻōnaehana.

3. I kēia mau lā, hoʻohana ka mea hoʻolale wela maʻamau i nā mea hoʻonaninani wela paʻakikī e like me ka cork a i ʻole polystyrene i hana ʻia ma mua. No ka mea, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i nā mea hana insulation thermal no ke kūkulu ʻana a ʻoi aku ka maikaʻi o ka hopena insulation thermal ma mua o ka mea i hana ʻia ma ka pūnaewele, no laila ua hoʻohana nui ʻia. Eia nō naʻe, no kēia ʻano o ka ʻāpana insulation i hōʻuluʻulu ʻia, inā ʻaʻole mālama pono ʻia ka papa pale mahu, e kahe ana ka mahu wai i ka lewa i loko o ka papa insulation mai nā āpau, a laila e luku ai i ka hana o ka papa insulation.

He aha nā mea hoʻokaʻawale no nā paipu mahu?

1. Paipu huluhulu pohaku,
Hoʻohana nui ʻia nā paipu hulu hipa no ka insulation thermal o nā boilers a i ʻole nā ​​pipeline lako i nā ʻoihana e like me ka petrochemical, metallurgy, ka hana moku, a me nā ʻoihana textile. Hoʻohana nui ʻia lākou i kekahi manawa i nā paia ʻāpana i ka ʻoihana kūkulu, a no ke keʻena o loko a me ka pale ʻana i ka paia a me nā ʻano ʻano wela wela. E mālama i ka mahana. Eia nō naʻe, i ka ʻoihana mana, ʻoihana petrochemical, ʻoihana māmā, a me nā mea ʻē aʻe, hoʻohana ʻia ka insulation a me nā ana insulation thermal o nā pipelines i nā pipelines like ʻole, ʻoi aku hoʻi no nā pipeline me nā puka liʻiliʻi. Hiki ke hoʻokō koke ʻia nā paipu huluhulu pōhaku wai. Loaʻa iā ia nā waiwai kūikawā e like me ke kūpaʻa o ka wai, ka wai a me ka wela. He kūpono no ka hoʻohana ʻana i nā wahi ua. Loaʻa iā ia ka pale wai.

2. Huluhulu aniani,
Loaʻa i ka hulu hipa aniani nā hiʻohiʻona o ka formability maikaʻi, haʻahaʻa leo haʻahaʻa, a me ka haʻahaʻa haʻahaʻa haʻahaʻa. He kiʻekiʻe loa ka pale ʻana i ka corrosion i ka hulu hipa aniani a loaʻa iā ia nā waiwai kemika maikaʻi i nā kaiapuni kemika. ʻO nā hiʻohiʻona hiki ke hoʻololi i ka huluhulu aniani no ka hoʻokaʻawale ʻana i nā ea, nā paipu hoʻopau, nā paila a me nā paipu mahu.

3. Urethane, polyurethane, ka mea i hoʻohana nui ʻia i ka hana ʻana i ka mālama anu, nā kaʻa pahu hau a i ʻole nā ​​pahu mālama hou. Hiki ke hoʻohana 'ia e like me ka wela insulation papa o kala kila sandwich panels. Hoʻohana ʻia ka polyurethane i nā pahu petrochemical i kekahi manawa. Loaʻa i ka Polyurethane ka hana o ka insulation thermal a me ka insulation anu, a hoʻohana ʻia i nā māla petrochemical a me metallurgical. Hoʻohana nui ʻia ia i ka pale o waho o nā ʻano like ʻole o lalo o ka lepo i kanu pololei ʻia i nā pipeline.
