Ka nānā ʻana i nā pono o nā olonā basalt no nā paipu kaomi kiʻekiʻe

ʻO ka olonā basaltʻO ka paipu kaomi kiʻekiʻe i hoʻohui ʻia, nona nā ʻano o ke kūpaʻa ʻana i ka pala, ke kaumaha māmā, ka ikaika kiʻekiʻe, ke kūpaʻa haʻahaʻa i ka lawe ʻana i nā wai a me ke ola lawelawe lōʻihi, ua hoʻohana nui ʻia i ka petrochemical, aviation, ke kūkulu ʻana a me nā ʻoihana ʻē aʻe. ʻO kona mau hiʻohiʻona nui: ke kūpaʻa ʻana i ka pala i ka H2S, CO2, ka wai paʻakai, a pēlā aku, ka hoʻonui haʻahaʻa, ka hoʻokumu ʻana o ka wax haʻahaʻa, ka hana kahe maikaʻi, ʻo ke coefficient kahe he 1.5 mau manawa o ka paipu kila, a i ka manawa like, he ikaika mechanical maikaʻi loa, ke kaumaha māmā, ke kumukūʻai hoʻonohonoho haʻahaʻa, ke ola lawelawe hoʻolālā ma mua o 30 mau makahiki, a i kekahi mau papahana, a ʻoiai ʻaʻohe pilikia o ka hoʻohana ʻana he 50 mau makahiki. ʻO kāna mau noi nui: nā paipu hoʻoili ʻaila maka, kinoea kūlohelohe a me ka wai hou; ka hoʻokomo wai ʻōpala, ka paipu ʻaila downhole a me nā paipu kaomi kiʻekiʻe ʻē aʻe; nā paipu hana petrochemical; nā paipu hoʻoili wai ʻaila a me ka mālama ʻana i ka wai ʻōpala; nā paipu wai wela a pēlā aku.

Kaʻina Hana Nui:
Hoʻohālikelike a me ka ʻokoʻa ma waenafiberglassa me ka paipu kaomi kiʻekiʻe o ka fiber basalt:
(1) ʻo ke ʻano kikoʻī like o ke kaulahao, ka pavement like, nā lako like a me kāna kaʻina hana e hōʻoia i ka ʻokoʻa ma waena o ke kaomi hydrostatic o ka basalt fiber/glass fiber pipeline (DN50PN7, no ka laʻana, EP/CBF pressure resistance o kahi o 30MPa, EP/GF pressure resistance o kahi o 25MPa); ʻo ke kiʻekiʻe like o ke kaomi, ʻo ka basalt fiber e pili ana i ka aniani fiber e hōʻemi i ka pavement o 10%, 20% e hōʻoia i ka pae maoli o ke kū'ē ʻana i ke kaomi hydrostatic (i DN50PN7) No ka laʻana, e hōʻemi i 2 mau papa EP/CBF pressure resistance o kahi o 25MPa).
(2) ʻO ka hoʻāʻo hope ma hope o ka hōʻemi ʻana i ke ala alanui e hōʻemi i ka hoʻohana ʻana i nā mea maka e hōʻemi i nā kumukūʻai huahana ua kāohi ʻia, ke kū nei ke kiʻekiʻe o ke kū'ē ʻana o ke kaomi o ka paipu i nā koi hoʻolālā, ke kumukūʻai opaipu fiberglasse pili ana i ka piʻi ʻole ʻana.

Nā pono hana paipu kiʻekiʻe o ka fiber basalt:
(1) kūpaʻa maikaʻi loa i ka palaho
ʻO ka olonā basaltUa māhele ʻia ke ʻano o ka paipu kila kiʻekiʻe i ʻekolu ʻāpana o ka papa lining, ka papa hoʻonohonoho a me ka papa pale waho. I waena o lākou, he kiʻekiʻe ka nui o ka resin o ka papa lining, ʻoi aku ma mua o 70%, a ʻo ka nui o ka resin o kona ʻili o loko he 95%. I ka hoʻohālikelike ʻana me ka paipu kila, he ʻoi aku ka maikaʻi o ke kūpaʻa ʻana i ka corrosion, e like me nā ʻano waikawa ikaika a me nā alkalis, nā ʻano paʻakai inorganic, nā mea hoʻoheheʻe oxidizing, hydrogen sulfide, carbon dioxide, nā ʻano surfactants, nā hopena polymer, nā ʻano solvents organic, a pēlā aku, inā koho ʻia kahi matrix resin maikaʻi, hiki i nā paipu basalt ke kūpaʻa lōʻihi (ʻaʻole i hoʻokomo ʻia ka waikawa concentrated, alkali ikaika, a me HF).
(2) Kū'ē maikaʻi i ka luhi a me ke ola lawelawe lōʻihi
ʻOi aku ka lōʻihi o ke ola o ka hoʻolālā ʻana o ka paipu basalt fiber kiʻekiʻe ma mua o 20 mau makahiki, a ʻo ka ʻoiaʻiʻo, pinepine ma hope o 30 mau makahiki o ka hoʻohana ʻana e mau ana ia, a ʻaʻohe ona mālama i kona ola lawelawe.
(3) Ka mana hoʻouka kaua kiʻekiʻe
ʻO ka pae kaomi maʻamau oolonā basaltʻO ka paipu kaomi kiʻekiʻe he 3.5MPa-25MPa (a hiki i ka 35 MPa, e like me ka mānoanoa o ka paia a me ka helu ʻana), i hoʻohālikelike ʻia me nā paipu ʻē aʻe ʻaʻole metala, ʻoi aku ke kiʻekiʻe o ka hiki ke kū i ke kaomi.
(4) Māmā ke kaumaha, maʻalahi ke kau ʻana a me ka halihali ʻana
ʻO ke kaumaha kikoʻī o ka paipu basalt fiber kiʻekiʻe ma kahi o 1.6, ʻo ke paipu kila wale nō a i ʻole ka paipu hao i hoʻolei ʻia he 1/4 ~ 1/5, hōʻike ka hoʻohana pono ʻana, ma lalo o ke kaomi kūloko like, ke anawaena like, ka lōʻihi like o ka paipu FRP, ʻo kona kaumaha ma kahi o 28% o ka paipu kila.
(5) ikaika kiʻekiʻe, nā waiwai mechanical kūpono
ʻO ka ikaika tensile axial o ka paipu basalt fiber kiʻekiʻe he 200 ~ 320MPa, kokoke i ka paipu kila, akā ʻoi aku ka ikaika ma mua o 4 mau manawa, i ka hoʻolālā kūkulu ʻana, hiki ke hoʻemi nui ʻia ke kaumaha o ka paipu, a maʻalahi loa ke kau ʻana.
(6) Nā waiwai ʻē aʻe:
ʻAʻole maʻalahi ke unahi a me ka wax, ke kūpaʻa haʻahaʻa o ke kahe ʻana, nā waiwai insulation uila maikaʻi, pili maʻalahi, ikaika kiʻekiʻe, conductivity thermal haʻahaʻa, haʻahaʻa thermal stress.
