ʻO ka paipu hoʻohuihui basalt fiber kiʻekiʻe-kaomi, nona nā ʻano o ke kūpaʻa ʻana i ka pala, ke kaumaha māmā, ka ikaika kiʻekiʻe, ke kūpaʻa haʻahaʻa e lawe i ka wai a me ke ola lawelawe lōʻihi, ua hoʻohana nui ʻia i ka petrochemical, aviation, kūkulu hale a me nā ʻoihana ʻē aʻe. ʻO kona mau hiʻohiʻona nui: ke kūpaʻa ʻana i ka pala o H2S, CO2, brine, a pēlā aku, ka hōʻiliʻili haʻahaʻa haʻahaʻa, ka waxing haʻahaʻa, ka hana kahe maikaʻi, ʻo ke coefficient kahe he 1.5 mau manawa o ka paipu kila, ʻoiai he ikaika mechanical maikaʻi loa, ke kaumaha māmā, ke kumukūʻai hoʻonohonoho haʻahaʻa, ke ola hoʻolālā ma mua o 30 mau makahiki, i kekahi mau papahana, ʻoiai he 50 mau makahiki ka hoʻohana ʻana ʻaʻohe pilikia. ʻO kāna mau noi nui: nā paipu hoʻoili ʻaila maka, kinoea kūlohelohe a me ka wai hou; nā paipu hoʻoili kiʻekiʻe-kaomi e like me ka injection wai a me nā paipu ʻaila downhole; nā paipu hana petrochemical; nā paipu hoʻoili wai ʻaila a me ka mālama wai ʻino; nā paipu spa, a pēlā aku.

Nā pono hana o ka paipu kaomi kiʻekiʻe o ka basalt fiber:
(1) Kū'ē maikaʻi loa i ka palaho
Ua māhele ʻia ke ʻano o ka paipu basalt fiber kiʻekiʻe i ʻekolu ʻāpana: ka papa o loko, ka papa kūkulu a me ka papa pale o waho. I waena o lākou, kiʻekiʻe ka nui o ka resin o ka papa o loko, ma ke ʻano maʻamau ma luna o 70%, a ʻo ka nui o ka resin o ka papa waiwai resin ma kona ʻili o loko e like me 95%. Ke hoʻohālikelike ʻia me nā paipu kila, ʻoi aku ka maikaʻi o kona kūpaʻa ʻana i ka palaho, e like me ka waikawa ikaika a me ka alkali, nā ʻano hoʻonā paʻakai inorganic like ʻole, nā mea hoʻoheheʻe oxidation, hydrogen sulfide, carbon dioxide, nā ʻano surfactants like ʻole, nā hoʻonā polymer, nā mea hoʻoheheʻe organik like ʻole, a pēlā aku. Inā koho maikaʻi ʻia ka matrix resin, hiki i nā paipu basalt fiber kiʻekiʻe ke kū i ka wā lōʻihi (koe wale nō ka waikawa i hoʻopaʻa ʻia, alkali ikaika a me HF).
(2) Kū'ē maikaʻi i ka luhi a me ke ola lawelawe lōʻihi
ʻOi aku ke ola hoʻolālā o ka paipu kiʻekiʻe o ka basalt fiber ma mua o 20 mau makahiki, a ʻo ka ʻoiaʻiʻo, ua paʻa pinepine ia ma hope o 30 mau makahiki o ka hoʻohana ʻana, a ʻaʻohe mālama pono i kona ola lawelawe.
(3) Ka mana hoʻouka kaua kiʻekiʻe
ʻO ka pae kaomi maʻamau o ka paipu kaomi kiʻekiʻe o ka fiber basalt he 3.5 MPa-25 MPa (a hiki i 35 MPa, ma muli o ka mānoanoa o ka paia a me ka helu ʻana), nona ke kūpaʻa kiʻekiʻe aʻe i ke kaomi i hoʻohālikelike ʻia me nā paipu ʻē aʻe ʻaʻole metala.
(4) Māmā ke kaumaha, maʻalahi ke hoʻouka a me ka lawe ʻana
ʻO ke kaumaha kikoʻī o ka paipu kiʻekiʻe o ka fiber Xuan Yan ma kahi o 1.6, ʻo ia wale nō 1/4 a 1/5 o ka paipu kila a i ʻole ka paipu hao i hoʻolei ʻia, a hōʻike ka noi maoli ma lalo o ke kumu o ke kaomi kūloko like, ʻo ke kaumaha o ka paipu FRP o ke anawaena like a me ka lōʻihi ma kahi o 28% o ko ka paipu kila.
(5) Ikaika kiʻekiʻe a me 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 kahe liʻiliʻi, nā waiwai insulation uila maikaʻi, ka hoʻopili maʻalahi, ka ikaika kiʻekiʻe, ka conductivity thermal haʻahaʻa, ke kaumaha thermal haʻahaʻa.
