Hana kēia loiloi i kahi loiloi i nā pono mālama ikehu i loa?a ma hope o ke kau ?ana i nā ?a?ahu insulation thermal ma nā valves a me nā lako. Ma mua o ka ho?oponopono hou ?ana, ua ho?opau nā ?āpana wela ki?eki?e o nā valves a me nā lako i ka nui o ka ikehu thermal ma o ka radiation a me ka convection, e hopena ana i ka ho?ohana ?ana i ka ikehu pono ?ole. I kēia manawa, ua ho?oki?eki?e ia i ka mahana ambient o ka ?āina a puni, kahi i ho?opilikia ai i ka ?olu?olu o ka hana a me ke kūpa?a o ka hana lako. Hiki i ka papa insulation i ho?okomo ?ia ke hō?emi i nā loli o ka mahana o nā lako, ho?emi i ka pō?ino o ke kaumaha thermal, a ho?oha?aha?a i ka helu hā?ule a me nā kumukū?ai mālama.

Hō?ike nā hopena ho?ā?o kahua: ?o ka mahana ambient o loko ma kahi o 45-60 ℃, a ?o ka mahana o ka ?ili i hō?ike ?ia o nā lako valve hana mai 110 ℃ a 190 ℃. ?O ka nalowale o ka wela ma nā hihia āpau ua ?oi aku ma mua o ka waiwai ho?ohehe?e wela i ?ae ?ia i kuhikuhi ?ia ma ke kūlana aupuni GB/T 8174-2008.

No ka loiloi pololei ?ana i ka waiwai mālama ikehu maoli o nā ?a?ahu insulation lako, ho?ohana kēia ho?ā?o i ke ?ano ho?ohālikelike "ma mua a ma hope": Ma lalo o ke kumumana?o he kūlike loa nā kūlana hana o nā lako (ka mahana hana, ka ukana, ka mahana ambient), ho?ohana ?ia nā mea hana ?oihana e like me nā mea ?ike mahana ki?eki?e, nā mika kahe wela, a me nā mika mana e nānā i ka mahana o ka ?ili o nā lako a me ka nalowale o ka ho?ohehe?e wela ma mua a ma hope o ke kau ?ana o nā ?a?ahu insulation. Ke lawe nei i nā ki?i ma kahi e like me ka la?ana: Ma kēia hi?ohi?ona ho?ā?o, i ka wā ?a?ole i ho?olako ?ia nā valves lako me nā ?a?ahu insulation, ho?oku?u mau ko lākou mau ?ili wela ki?eki?e i ka wela i waho, e hopena ana i ka mahana hana a hiki i 120 ℃-200 ℃. Ma hope o ke kau ?ana o nā ?a?ahu insulation, ua ālai pono ?ia ka ho?ohehe?e ?ana o ka ikehu wela, a ua ho?emi pololei ?ia ka mahana a puni nā lako i kahi o 35 ℃-45 ℃. —— Ma hope o ke kau ?ana i nā ?a?ahu insulation ma nā pipeline lako a me nā valves ma ka hale hana ho?oma?ema?e, ua ho?oha?aha?a nui ?ia ka mahana i kahi o 40 ℃, e ho?okō pono ana i nā koi mahana hana ma?amau no nā lako. Ua ho?okō nā ana insulation i nā hopena kupaianaha, e hō?oia pono ana i ka hana pa?a o nā lako.

Eia kahi hō?ili?ili o nā hi?ohi?ona ho?onohonoho maoli o nā uhi insulation ma?amau a mākou i hana ai no nā mea kū?ai aku. ?O ka hana ?ana a me ke kau ?ana o kēlā me kēia uhi insulation e hō?ike ana i ka hana lima pa?a.

Hana ?ia me ka mālama pono, ua ho?olālā ?ia lākou e pale i nā hana hana a kā mākou mea kū?ai aku.

He papahana kēia a mākou i hana ai no kā mākou mea kū?ai aku. ?O ka insulation holo?oko?a o ka pahu lako ?o kā mākou mea hou, ?a?ole nā ????mea ku?una e like me ka huluhulu aniani hu?a, akā ?o ka pena pale nano-kaiapuni no kēia pahu lako nui.
