Pākē 3PE anticorrosive kila paipu mea hana
1. E ho'ēmi i ke kumukūʻai o ka papahana
E like me ka helu ʻana o nā keʻena kūpono, ʻo ka maʻamau, hiki i ka polyurethane insulated steel pipe ke hoʻemi i ke kumukūʻai o ka papahana ma kahi o 25% (e hoʻohana ana i ka FRP ma ke ʻano he pale pale) a me 10% (hoʻohana ʻana i ka polyethylene kiʻekiʻe kiʻekiʻe ma ke ʻano he pale pale).
2. Haʻahaʻa wela lilo a me ka ikehu hoola
ʻO ka thermal conductivity o ka polyurethane: λ= 0.013-0.03kcal / m · h · OC, ʻoi aku ka haʻahaʻa ma mua o nā mea hoʻonaninani pipeline maʻamau i hoʻohana ʻia i ka wā ma mua, a ua hoʻomaikaʻi ʻia ka hopena insulation e 4 ~ 9 mau manawa. Eia kekahi, he haʻahaʻa loa kona komo ʻana i ka wai, ma kahi o 0.2kg/m2. ʻO ke kumu o ka haʻahaʻa haʻahaʻa wai ʻo ia ka polyurethane foam i pani ʻia ma kahi o 92%. ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka haʻahaʻa wai haʻahaʻa, me ka papa insulation thermal a me ka polyethylene kiʻekiʻe kiʻekiʻe a i ʻole FRP pale pale me ka hana wai ʻole maikaʻi ma waho, ua hoʻololi i ke kūlana o ka "ʻaʻahu ʻana i ka pulupulu pulu i hoʻopaʻa ʻia" o ka ʻauwaha kuʻuna e waiho ana i ka pipeline wela, a nui loa. hoemi i ka pau wela o ka paipu lako wela. ʻO ka wela wela o ka pūnaewele wela he 2%, ʻoi aku ka liʻiliʻi ma mua o ke koi maʻamau o ka honua o 10%.
3. Anti corrosion, insulation maikaʻi a me ke ola lawelawe lōʻihi
Ma muli o ka paʻa paʻa ʻana o ka polyurethane rigid foam insulation layer i ka ʻili o waho o ka paipu kila, hiki ke hoʻokaʻawale ʻia ka infiltration o ka ea a me ka wai, a hiki ke loaʻa ka hopena anticorrosion maikaʻi. I ka manawa like, ua pani ʻia kona mau pores huʻihaʻi a ua liʻiliʻi loa kona komo ʻana i ka wai. ʻO ka pūpū polyethylene kiʻekiʻe a me ka pūpū FRP he maikaʻi ka anti-corrosion, insulation a me nā waiwai mechanical. No laila, paʻakikī ka ʻili o waho o ka paipu kila e hoʻopau ʻia e ka ea o waho a me ka wai. Ke mālama maikaʻi ʻia ka maikaʻi o ka wai o loko o ka pipeline, e like me ka ʻikepili haole, hiki ke ola o ka lawelawe ma mua o 50 mau makahiki, ʻo ia ka 3 ~ 4 mau manawa lōʻihi ma mua o ka waiho ʻana o ka auwaha kuʻuna a me ka waiho ʻana i luna.
Ke hoʻohālikelike ʻia me ke ʻano hoʻokaʻawale ʻana o ka paipu kila maʻamau, ʻoi aku ka maikaʻi o ka paipu kila i kanu ʻia i hoʻopaʻa ʻia:
1.ʻAʻole pono ke kūkulu ʻana i kahi auwaha nui i hoʻopaʻa mua ʻia i kanu ʻia i ka paipu insulated ma lalo o ka lepo, ka mea e hōʻemi nui ai i ka noho ʻana o ka ʻāina o ka papahana, kūpono i ka mālama ʻana i ke kaiapuni, e hoʻemi ana i ka nui o ka ʻeli ʻana i ka lepo. ma mua o 50%, a ho'ēmi i ka nui o ka masonry kivila a me ka koneki ma 90%. I ka manawa like, hana ʻia ke kūkulu ʻia ʻana o ka paipu insulation e like me ka ʻauwaha ma luna o ka pūnaewele, a ʻo ka hui ʻana ma ka pūnaewele wale nō e koi ʻia, hiki ke hōʻemi i ka manawa hana ma mua o 50%.
2.He maikaʻi ka hana mālama wela, a he 25% wale nō ka nalowale o ka wela o nā paipu kuʻuna. Hiki i ka hana lōʻihi ke mālama i ka ikehu a hoʻemi nui i ke kumukūʻai ikehu.
3.He ikaika ka wai a me ka corrosion. ʻAʻole pono e hoʻopili i kahi auwaha paipu. Hiki ke kanu pololei ʻia i ka lepo a i ʻole ka wai. He maʻalahi a wikiwiki hoʻi ke kūkulu ʻana, a he haʻahaʻa ke kumukūʻai piha.
4. Loaʻa iā ia ka pale corrosion maikaʻi a me ke kūpaʻa hopena ma lalo o nā kūlana haʻahaʻa haʻahaʻa, a hiki ke kanu pololei ʻia i loko o ka lepo maloʻo maloʻo.
5.Hiki i ke ola lawelawe ke hiki i 30-50 mau makahiki. Hiki i ka hoʻonohonoho pono ʻana a me ka hoʻohana ʻana ke hoʻohaʻahaʻa loa i ke kumukūʻai mālama o ka pūnaewele paipu.
6. Hiki ke hoʻonohonoho ʻia ka ʻōnaehana alarm e ʻike maʻalahi i ka hewa leakage o ka pūnaewele paipu, hōʻike pololei i ka wahi hewa a me ke ala ala.
