ʻO ka pipe thermoplastic reinforced (RTP) he huaʻōlelo maʻamau e pili ana i kahi fiber synthetic ikaika kiʻekiʻe (e like me ke aniani, aramid a i ʻole carbon), i hoʻokumu mua ʻia i nā makahiki 1990 mua e Wavin Repox, Akzo Nobel a me Tubes d'Aquitaine mai Farani, nāna. ua hoʻomohala i nā paipu mua i hoʻoikaika ʻia me ka fiber synthetic e pani ai i nā paipu kila puʻupuʻu i ka pane ʻana i ka ulu ʻana o ka noi no nā conduits non-corrosive no ka noi ʻana i ka ʻoihana ʻaila a me ke kinoea ma kahakai, ʻo ia hoʻi ma ka Middle East. ʻO ka paipu paha he Polyethylene (PE), Polyamide-11 a i ʻole PVDF a hiki ke hoʻoikaika ʻia me ka fiber Aramid a i ʻole Polyester inā hoʻohana ʻia nā hui ʻē aʻe.
ʻO ka mea i hala koke aku nei ka ʻenehana o ka hana ʻana i ia paipu, me ke kūʻai aku ʻana, hoʻomaha me kekahi mau ʻoihana nui, ʻo ia ʻo Pipelife me Soluforce kahi e loaʻa ai i nā coils a hiki i 400 m (1,312 ft) lōʻihi.Loaʻa kēia mau paipu i nā helu kaomi mai 30 a 90 bar (3 a 9 MPa; 435 a 1,305 psi).I loko o nā makahiki i hala iho nei, ua ʻike ʻia kēia ʻano paipu ma ke ʻano he hopena ʻokoʻa maʻamau i ke kila no ka hoʻohana ʻana i nā laina kahe wai e kekahi mau hui aila a me nā mea hana.ʻO ka pōmaikaʻi nui o kēia paipu ʻo ia hoʻi kona manawa hoʻokomo wikiwiki loa e hoʻohālikelike ʻia me ka paipu kila i ka wā e noʻonoʻo ai i ka manawa wili e like me ka awelika o ka wikiwiki a hiki i 1,000 m (3,281 ft) / lā i hiki ke kau i ka RTP ma ka ʻili honua.
ʻO ka mea mua, hāʻawi ka paipu i ka pōmaikaʻi i nā noi kahi e haki ai ke kila ma muli o ka corrosion a he pilikia ka manawa hoʻonohonoho.
ʻO ka PTFE he polymer thermoplastic, he paʻa keʻokeʻo ma ka lumi wela, me ka nui o 2200 kg / m3.Wahi a Chemours, ʻo 600 K (327 °C; 620 °F) kona wahi hehee.[19]Mālama ʻo ia i ka ikaika kiʻekiʻe, paʻakikī a me ka lubrication ponoʻī ma nā haʻahaʻa haʻahaʻa a hiki i 5 K (−268.15 °C; −450.67 °F), a me ka hoʻololi maikaʻi i nā mahana ma luna o 194 K (−79 °C; −110 °F).Loaʻa ka PTFE i kāna mau waiwai mai ka hopena aggregate o nā kaula kalapona-fluorine, e like me nā fluorocarbons a pau.ʻO nā kemika wale nō i ʻike ʻia e pili ana i kēia mau mea paʻa kalapona-fluorine he mau metala reactive loa e like me nā metala alkali, a ma nā mahana kiʻekiʻe e like me nā metala e like me ka aluminika a me ka magnesium, a me nā mea hana fluorinating e like me xenon difluoride a me cobalt(III) fluoride.
ʻO ka coefficient o ka friction o nā plastics e ana maʻamau e pili ana i ke kila i poni ʻia. ʻO ka coefficient o friction o PTFE he 0.05 a i ka 0.10, ʻo ia ke kolu-haʻahaʻa loa o kekahi mea paʻa i ʻike ʻia (BAM ka mea mua, me ka coefficient o friction o 0.02; daimana-like. ʻO ke kalapona ka lua-haʻahaʻa loa ma ka 0.05).ʻO ke kūʻē ʻana o PTFE i nā pūʻali van der Waals, ʻo ia wale nō ka ʻili i ʻike ʻia kahi hiki ʻole i ka gecko ke pili.ʻO ka ʻoiaʻiʻo, hiki ke hoʻohana ʻia ka PTFE e pale aku i ka piʻi ʻana o nā pepeke i luna i pena ʻia me ka mea.He pahee loa ka PTFE i hiki ole ai i na inike ke hopu a haule iho.No ka laʻana, hoʻohana ʻia ʻo PTFE e pale aku i ka piʻi ʻana o nā ʻanuʻu mai ka formicaria.
