ʻO nā paipu pulupulu poliester he mau paipu hikiwawe kiʻekiʻe i hana nui ʻia me ka lāʻau synthetic, i hoʻoikaika ʻia me nā fiber polyester a i ʻole uea kila. Hoʻohana nui ʻia lākou i nā ʻoihana ʻenehana, mahiʻai, a me nā ʻenehana mīkini. ʻO kā lākou kūpaʻa paʻi maikaʻi loa, ka pale ʻana i ka abrasion, a me ke kūpaʻa kemika e lilo lākou i mea hoʻonā kūpono no nā ʻōnaehana lawe wai.
ʻO ka hoʻonohonoho ʻana, ʻo nā paipu pulupulu polyester ka mea maʻamau i loko o kahi ʻāpana ʻōpala i loko, kahi papa hoʻoikaika, a me kahi papa ʻōpala waho. Ho'ohana 'ia ka pa'ipa'i o loko, e pili pono ana me ka mea i lawe 'ia, e ho'ohana 'ia nā mea 'olopika 'oi loa a 'ino'ino (e like me ka rubber nitrile a me ka rubber EPDM) no ka ho'opa'a 'ana i ka leak{2}}a me ke ola lō'ihi. Hāʻawi ka papa hoʻoikaika paʻa waena i ke kūpaʻa ʻana ma o ke kaula polyester a i ʻole nā kaʻina hana wili wili kila, hiki ke kū i nā kaomi hana a hiki i nā haneli Pascals. Loaʻa i ka papa ʻōpala o waho ke kūpaʻa abrasion, ka pale ʻana o UV, a me ke koʻikoʻi koʻikoʻi o ke kaiapuni, kūpono ia no nā kūlana hana waho a paʻakikī paha.
ʻO ka pōmaikaʻi nui o kēia huahana aia i kāna hana piha kaulike. Ma ke ʻano o ke kūpaʻa kemika, hōʻike ʻia nā paipu polyester rubber i ke kūʻē maikaʻi ʻana i ka media e like me ka aila, nā wahie, a me nā solution acid/alkali, e kūpono ana iā lākou no nā ʻōnaehana hydraulic a i ʻole ka lawe ʻana i nā wai corrosive i nā ʻoihana e like me ka hana automotive a me nā petrochemical. Ma ke ʻano o nā waiwai mechanical, hiki ke piʻi kona puʻe ʻana i 3-5 manawa o ke kaomi hana, a he maʻalahi loa ia, hoʻomaʻamaʻa i ka hoʻokomo ʻana a me ka hoʻopili ʻana i nā hana ma nā kaiapuni paʻakikī. Eia kekahi, ua hōʻoia ʻia kekahi mau hiʻohiʻona e like me ka lāʻau lapaʻau meaʻai, kūpono no ka lawe ʻana i ka wai maʻemaʻe i loko o ka wai inu a i ʻole nā noi hana meaʻai.
Ma nā hi'ohi'ona ho'ohana, ho'ohana nui 'ia nā pu'upu'u polyester no ka ho'ohehe'e 'ana i ka wai, -ki'eki'e ki'eki'e i loko o ka 'eli 'ana, nā kaapuni hydraulic i nā mīkini hana, ki'eki'e-nā mea ho'ohu wai no ka ho'oulu 'ana i ka mahi'ai, a me ka mālama 'ana i ka wai kūikawā ma nā lako kai a me ka lewa. I kēia mau makahiki i hala iho nei, me ka holomua ʻana i ka ʻepekema waiwai, ua komo mālie i ka mākeke ke kiʻekiʻe -ka wela (-40 degere a hiki i ka +150 degere ), māmā, a me ke kaiapuni i ka mākeke, e hoʻonui ana i ko lākou mau palena noi.
Pono e hoʻomaopopo ʻia ʻo ke koho kūpono e pono ai ka noʻonoʻo piha ʻana i ke ʻano waena, ka pae wela, a me ka helu kaomi. ʻO ka nānā mau ʻana no ka ʻelemakule a me ka ʻaʻahu ʻana i ke kino o ka paipu a me ka pale ʻana i ka hoʻouka ʻana he mea koʻikoʻi ia no ka hōʻoia ʻana i ka hana paʻa - lōʻihi. Ma ke ʻano he mea koʻikoʻi i ka ʻoihana ʻoihana, hoʻomau ka hāʻawi ʻana i nā hose rubber polyester i ke kākoʻo kūpono no nā kaʻina hana hou ma muli o kā lākou hana hilinaʻi a me ka hoʻokele waiwai.
