ʻO nā paipu i hoʻopaʻa ʻia

ʻO ka paipu insulated he ʻōnaehana paipu me ka wela wela. ʻO kāna hana koʻikoʻi ka hoʻemi ʻana i ka wela i ka wā o ka lawe ʻana i nā media (e like me ka wai wela, ka mahu, a me ka aila wela) i loko o ka paipu ʻoiai e pale ana i ka paipu mai nā hopena o ke kaiapuni. Hoʻohana nui ʻia ia i ke kūkulu ʻana i ka hoʻomehana, ka hoʻomehana ʻāina, ka petrochemical, ka ʻenekinia municipal, a me nā māla ʻē aʻe.

1. Hoʻokumu kumu

ʻO ka paipu insulated ka mea maʻamau he ʻano hoʻohuihui multi-layer i ʻekolu mau mea nui:

• Pipe kila hana: ʻO ka papa o loko, kuleana no ka lawe ʻana i ka media. ʻO ka mea maʻamau, ʻo ia ke kila maʻemaʻe, ke kila galvanized, a i ʻole nā ​​paipu plastik, a pono e pale i ke kaomi a me ka ʻino.

• Layer Insulation: ʻO ka papa waena koʻikoʻi, kuleana no ka hoʻopuʻi wela. ʻO nā mea maʻamau ka polyurethane foam, ka hulu pōhaku, ka hulu aniani, a me ka polyethylene. ʻO ka polyurethane foam i kēia manawa ke koho nui ma muli o kona haʻahaʻa haʻahaʻa haʻahaʻa a me ka hana insulation maikaʻi loa.

• Outer Sheath: ʻO ka papa pale o waho e pale ai i ka papa insulation mai ka makū, kaʻelemakule, a me kaʻino mechanical. Loaʻa nā mea maʻamau i ka polyethylene kiʻekiʻe (HDPE), fiberglass, a i ʻole ka uhi anti-corrosion.

II. ʻAno nui a me nā ʻano

Ma muli o ka mea insulation a me ka hoʻohana ʻana i ke ʻano, nā ʻano maʻamau a me nā hiʻohiʻona penei:

• Polyurethane Insulated Pipe: Thermal conductivity ≤ 0.024 W/(m·K), kiʻekiʻe insulation maikaʻi, haʻahaʻa-mahana kū'ē, a me ka elemakule kū'ē. He kūpono no ka wai wela a me nā paipu mahu me nā mahana ma waena o -50 ° C a me 120 ° C, ʻo ia ka mea i koho ʻia no ka hoʻomehana waena a me nā ʻōnaehana hoʻomehana papahele.

• Rockwool Insulated Pipe: Ke kū'ē i ka wela kiʻekiʻe (hiki i ka 600 ° C) a me ka helu ahi kiʻekiʻe (Class A non-combustible), akā me ka hoʻoulu wai kiʻekiʻe, pono ia i ka moisture-proofing. Hoʻohana mua ʻia ia no nā pipelines wela wela o ka ʻoihana (e like me nā paipu mahu paila).

• Glass Wool Insulated Pipe: Māmā, me ke kani maikaʻi maikaʻi, a me keʻano pale wela o -120 ° C a hiki i 400 ° C, he kūpono ia no nā paipu haʻahaʻa haʻahaʻa (e like me nā paipu hoʻoheheʻe hau) a no ka hoʻokuʻuʻana i nā paipu ma nā hale kīwila.

III. Pono Pono

1. Hoʻemi ʻana i ka ikehu a me ka hoʻemi ʻana: E hoʻemi i ka nalowale o ka wela ma ka waena, e hoʻohaʻahaʻa 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 hoʻemi nui i nā kumukūʻai hana.

2. Palekana Pipeline: Ke pale aku nei ka puʻu o waho i ka wai, ka ʻinoʻino o ka lepo, a me ka hopena mechanical, e hoʻolōʻihi i ke ola o ka paipu a me ka hoʻemi ʻana i ka mālama ʻana.

3. Ka Hana Pipeline Stable: E mālama i ka mahana wela paʻa no ka pale ʻana i ka fluctuations o ka mahana mai ka hoʻopili ʻana i ka hana (e like me ka mālama ʻana i ka mahana o loko no nā paipu wela a me ka hōʻoia ʻana i ka paʻa o ke kaʻina hana no nā paipu ʻoihana).

4. Hoʻokomo maʻalahi: Ua hana mua ʻia kekahi mau paipu insulated, e koi wale ana i ka pilina ma ka pūnaewele a me ka hoʻokomo ʻana, e hoʻopōkole i ka manawa hana a hoʻemi i ka paʻakikī.

IV. Nā noi pili

• Kaona: ʻO nā pūnaewele hoʻomehana kūloko kūloko a me nā paipu wai paipu (e pale i ka hau i ka hoʻoilo).

• Ke kukulu ana: Na paipu wela o ka papahele ma na hale noho a me na hale kalepa, a me na paipu mehana a me ka hooluolu no ka ea ea waena.

• ʻOihana: ʻO nā paipu aila wela i ka ʻaila a me nā ʻoihana kemika, nā paipu mahu i nā mea kanu mana, a me nā pipelines cryogenic medium i loko o ka logistics kaulahao anuanu.
