No nā mea nona nā kikowaena kinoea kūʻai liʻiliʻi a me nā mea hoʻokele, he paʻakikī ke loaʻa ʻana o nā ʻāpana paipu a me nā ʻōnaehana wahie i hana ʻia me ka fiberglass ma muli o ka nele o ka resin, e paʻakikī ai ke loaʻa ʻana o nā hoʻonohonoho paipu vent (UST) no nā pahu mālama ma lalo o ka honua. Ke pale nei kēia mau hemahema i ke kau ʻana o nā ʻōnaehana hou a i ʻole i hoʻomaikaʻi ʻia, no ka mea, he ʻāpana pono ka hoʻopau ʻana i nā hoʻonohonoho hoʻopiha hou ʻana i kona holo ʻana mai ka UST a i ka hoʻopau ʻana o ka vacuum kaomi o ka ʻōnaehana.
He mea koʻikoʻi ka laina hoʻokuʻu wai no ka hana o ka ʻōnaehana UST no ka mea e ʻae ai i ka pahu e hoʻokuʻu i ka wai ke ʻoi aku kona kaomi kūloko a i ʻole ka vacuum ma mua o kahi kiko, e ʻae ana i ka pahu e "hanu". ʻOiai he mea hoʻonāukiuki ka nele o ka fiberglass, aia kahi hopena i hōʻoia ʻia a maʻalahi hoʻi: nā ducts hoʻokuʻu wai.
Hāʻawi ʻo Frustration-Free Vent PipesOPW i kahi laulā piha o nā nui a me nā lōʻihi o nā paipu hoʻopau palupalu, ua hoʻolālā ʻia a ʻae ʻia nā mea āpau e hāʻawi i nā pono he nui ke hoʻohana ʻia me nā ʻano wahie mīkini like ʻole i loaʻa i kēia manawa ma ka mākeke petroleum.
Ua hoʻohana ʻia nā hose i nā hoʻonohonoho ʻōnaehana wahie no nā makahiki he 25 a ʻoi, ʻo ia hoʻi e hāʻawi i kahi pili ma waena o ka UST a me ka mea hoʻopuka wahie. Eia kekahi, i ka makahiki 2004, ua hoʻohui ʻo UL/ULc i ka inoa "Common Exhaust" i kāna UL-971 "Standard for the Safety of Nonmetallic Underground Piping for Flammable Liquids," e hana ana i ka paipu maʻalahi i koho mua no nā hoʻonohonoho ʻōnaehana wahie. Ka lawelawe ʻana i nā huahana wai a me nā noi venting.
ʻO nā pono o ka paipu palupalu ke hoʻohana ʻia ma ke ʻano he paipu hoʻokuʻu UST e like me ka wā e hoʻohana ʻia ai i nā noi lawe wahie:
Ke hoʻohālikelike ʻia me nā mea ʻē aʻe i hoʻohana ʻia no ka hana ʻana i nā paipu hoʻoulu ea, hāʻawi pū nā paipu palupalu i nā pono penei:
Ua hoʻomaka ʻo OPW Retail Fueling ma Smithfield, NC i kāna laina huahana FlexWorks i ka makahiki 1996. Mai ia manawa, ua kūʻai ʻia aku ma mua o 10 miliona kapuaʻi o ka paipu palupalu - i helu ʻia e UL no ka hoʻoulu ʻana i ka ea i ka makahiki 2007 - no ka hoʻohana ʻana i nā wahie kaʻa, nā wahie hui kiʻekiʻe, nā wahie i hoʻonui ʻia, a me nā wahie mokulele a me ke kai a puni ka honua.
Loaʻa ka OPW Flexible Tubing i nā hoʻonohonoho pā hoʻokahi a me ka pā pālua, a loaʻa pū kekahi i nā lōʻihi like ʻole ma nā wili a i ʻole ma nā "koʻokoʻo" pālahalaha he 25, 33, a me 40 kapuaʻi me nā anawaena o 1.5, 2, a me 3 ʻīniha, kēlā me kēia. Wahi a PEI/RP 100-20 "Nā Hana i Manaʻo ʻia no ka Hoʻokomo ʻana i nā ʻōnaehana mālama wai ma lalo o ka honua." ʻOi aku ka hele ʻana o OPW ma mua o ka ʻōlelo a PEI/RP 100-20, kahi e ʻōlelo ai e hoʻokiʻekiʻe ʻia nā ala ea i 1/4 ʻīniha no ka wāwae, ʻaʻole i ʻōlelo ʻia e PEI he 1/8 ʻīniha no ka wāwae.
Pono e hana ʻia nā pilina paipu hoʻopau palupalu me ke kila kila a hiki ke hoʻokomo ʻia i loko o nā keʻena hoʻololi a i ʻole nā ​​​​sumps, ʻoi aku hoʻi ma nā mokuʻāina kahi e pono ai ka paipu pā pālua. Inā ʻaʻole loaʻa nā mea kila kila a i ʻole nā ​​​​​​pā aila hoʻololi, pono e kāʻei ʻia nā pilina me ka lipine Densyl™ (i ʻike ʻia hoʻi he lipine grease a i ʻole ka lipine wax) e pale aku i ka pala.
I loko o nā makahiki he 25 mai kona hoʻokumu ʻia ʻana, ua hana ʻo OPW i nā hoʻonui i kāna paipu palupalu FlexWorks, me ka hoʻonui ʻana i ka maʻalahi me ka ikaika kulou liʻiliʻi a me ke kau ʻana maʻalahi; ua hoʻemi ʻia ke kaumaha o ka paipu e hōʻemi i nā kumukūʻai hoʻouna; a ua hoʻemi nui ʻia ka hoʻomanaʻo paipu e hoʻokō ai i nā pilina wikiwiki a me ka hiki ke kau palahalaha i ka paipu i loko o ka ʻauwaha; a hoʻohana i kahi liner paipu Kynar® ADX (PVDF) i hoʻoikaika ʻia, ʻoi aku ka paʻa a ʻoi aku ka pale ʻana i ka permeation, e kūpono ai no ka hōʻike ʻana i ka wai a me ka mahu.
Ma hope o nā makahiki he ʻumi o ka hōʻoia ʻana i kona waiwai ma ke ʻano he ʻāpana o nā ʻōnaehana hoʻouna wahie ma lalo o ka honua, ke lilo koke nei ka paipu palupalu i koho mua no nā noi paipu hoʻopuka makani, a ʻo ka fiberglass crunch o kēia manawa kekahi kumu e lilo ai ka paipu hoʻopuka makani palupalu i mea hilinaʻi ʻē aʻe i ka paipu hoʻopuka makani paʻa. a i ʻole ka paipu fiberglass semi-rigid.
