Reinforced thermoplastic pipe (RTP) ndi liwu lodziwika bwino lomwe limatanthawuza ulusi wodalirika wamphamvu (monga galasi, aramid kapena kaboni), yomwe idapangidwa koyambirira kwa zaka za m'ma 1990 ndi Wavin Repox, Akzo Nobel komanso Tubes d'Aquitaine waku France, yemwe. adapanga mapaipi oyamba olimbikitsidwa ndi ulusi wopangidwa kuti alowe m'malo mwa mipope yachitsulo yapakatikati potengera kuchuluka kwa mipope yopanda dzimbiri kuti igwiritsidwe ntchito pamakampani akunyanja amafuta ndi gasi, makamaka ku Middle East. Nthawi zambiri, zida zomwe zimagwiritsidwa ntchito pomanga chitoliro chikhoza kukhala Polyethylene (PE), Polyamide-11 kapena PVDF ndipo chikhoza kulimbikitsidwa ndi Aramid kapena Polyester fiber ngakhale zosakaniza zina zimagwiritsidwa ntchito.
Posachedwapa teknoloji yopanga chitoliro choterocho, kuphatikizapo malonda, imakhala ndi makampani angapo ofunika kwambiri, omwe ndi Pipelife ndi Soluforce komwe amapezeka muzitsulo mpaka 400 m (1,312 ft) kutalika.Mapaipi awa amapezeka pamiyeso yokakamiza kuchokera ku 30 mpaka 90 bar (3 mpaka 9 MPa; 435 mpaka 1,305 psi).Pazaka zingapo zapitazi mtundu uwu wa chitoliro wavomerezedwa ngati njira yothetsera zitsulo zopangira mafuta opangira mafuta ndi makampani ena amafuta ndi oyendetsa.Ubwino waukulu wa chitoliro ichi nayenso mofulumira kwambiri unsembe nthawi poyerekeza ndi zitsulo chitoliro poganizira nthawi kuwotcherera monga pafupifupi liwiro mpaka 1,000 m (3,281 ft)/tsiku afika khazikitsa RTP padziko lapansi.
Makamaka, chitolirocho chimapereka phindu kwa ntchito zomwe zitsulo zimatha kuphulika chifukwa cha dzimbiri ndi nthawi yoyika ndi vuto.
PTFE ndi polima thermoplastic, amene ndi woyera olimba kutentha firiji, ndi kachulukidwe za 2200 makilogalamu/m3.Malinga ndi Chemours, malo ake osungunuka ndi 600 K (327 °C; 620 °F).[19]Imasunga mphamvu zambiri, kulimba ndi kudzipaka paokha kutentha kwa 5 K (−268.15 °C; -450.67 °F), komanso kusinthasintha kwabwino pa kutentha pamwamba pa 194 K (−79 °C; -110 °F).PTFE imapindula ndi mphamvu zake kuchokera kumagulu a carbon-fluorine bond, monganso ma fluorocarbons onse.Mankhwala okhawo omwe amadziwika kuti amakhudza zomangira za carbon-fluorine ndi zitsulo zogwira ntchito kwambiri monga zitsulo za alkali, komanso kutentha kwambiri komanso zitsulo monga aluminiyamu ndi magnesium, ndi fluorinating agents monga xenon difluoride ndi cobalt (III) fluoride.
Coefficient of friction of plastics nthawi zambiri amayezedwa ndi chitsulo chopukutidwa.PTFE's coefficient of friction ndi 0.05 mpaka 0.10, yomwe ili yachitatu yotsika kwambiri pazinthu zolimba zomwe zimadziwika (BAM kukhala yoyamba, yokhala ndi coefficient of 0.02; ngati diamondi kaboni kukhala wachiwiri wotsika kwambiri pa 0.05).Kukaniza kwa PTFE ku mphamvu za van der Waals kumatanthauza kuti ndi malo okhawo odziwika omwe nalimata sangathe kumamatira.M'malo mwake, PTFE itha kugwiritsidwa ntchito kuteteza tizilombo kukwera pamalo opaka utoto ndi zinthuzo.PTFE ndi yoterera kotero kuti tizilombo sitingathe kugwira ndipo timakonda kugwa.Mwachitsanzo, PTFE imagwiritsidwa ntchito poletsa nyerere kutuluka mu formicaria.
