Reinforced thermoplastic yeeb nkab (RTP) yog ib lub ntsiab lus hais txog lub zog muaj zog hluavtaws fiber ntau (xws li iav, aramid lossis carbon), pib tsim thaum xyoo 1990 los ntawm Wavin Repox, Akzo Nobel thiab los ntawm Tubes d'Aquitaine los ntawm Fabkis, leej twg. tsim thawj cov kav dej txuas ntxiv nrog cov hluavtaws fiber ntau los hloov cov kav dej nruab nrab siab hauv cov lus teb rau qhov kev thov loj hlob ntawm cov kav dej tsis muaj corrosive rau daim ntawv thov hauv kev lag luam onshore roj thiab roj, tshwj xeeb tshaj yog nyob rau hauv Middle East. Feem ntau, cov ntaub ntawv siv hauv kev tsim kho cov yeeb nkab tej zaum yuav yog Polyethylene (PE), Polyamide-11 los yog PVDF thiab tej zaum yuav muaj zog nrog Aramid los yog Polyester fiber ntau txawm tias siv lwm yam kev sib txuas.
Tsis ntev los no cov thev naus laus zis ntawm kev tsim cov yeeb nkab zoo li no, suav nrog kev lag luam, so nrog ob peb lub tuam txhab tseem ceeb, ib qho yog Pipelife nrog Soluforce qhov twg nws muaj nyob rau hauv coils txog li 400 m (1,312 ft) ntev.Cov kav dej no muaj nyob rau hauv qhov ntsuas siab ntawm 30 txog 90 bar (3 txog 9 MPa; 435 txog 1,305 psi).Ob peb xyoos dhau los no cov yeeb nkab no tau lees paub tias yog cov txheej txheem kev daws teeb meem rau steel rau oilfield flowline daim ntawv thov los ntawm qee cov tuam txhab roj thiab cov neeg ua haujlwm.Qhov txiaj ntsig zoo ntawm cov yeeb nkab no kuj yog nws lub sijhawm teeb tsa nrawm heev piv rau cov yeeb nkab steel thaum xav txog lub sijhawm vuam raws li qhov nruab nrab ceev txog 1,000 m (3,281 ft) / hnub tau mus txog txhim kho RTP hauv av.
Feem ntau, cov yeeb nkab muab txiaj ntsig rau cov ntawv thov uas cov hlau tuaj yeem tawg vim corrosion thiab lub sijhawm teeb tsa yog qhov teeb meem.
PTFE yog ib qho thermoplastic polymer, uas yog cov khoom dawb ntawm chav tsev kub, nrog qhov ceev ntawm li 2200 kg / m3.Raws li Chemours, nws melting point yog 600 K (327 ° C; 620 ° F).[19]Nws tuav lub zog siab, toughness thiab nws tus kheej lubrication ntawm qhov kub qis mus rau 5 K (−268.15 ° C; −450.67 ° F), thiab ua tau zoo ntawm qhov kub siab tshaj 194 K (-79 ° C; -110 ° F).PTFE tau txais nws cov khoom los ntawm kev sib sau ua ke ntawm carbon-fluorine bonds, zoo li tag nrho cov fluorocarbons.Tsuas yog cov tshuaj uas paub tias cuam tshuam rau cov carbon-fluorine bonds yog cov hlau reactive zoo li cov hlau alkali, thiab nyob rau ntawm qhov kub siab dua kuj xws li hlau xws li txhuas thiab magnesium, thiab cov tshuaj fluorinating xws li xenon difluoride thiab cobalt (III) fluoride.
Cov coefficient ntawm kev sib txhuam ntawm cov yas feem ntau yog ntsuas tawm tsam polished steel.PTFE tus coefficient ntawm kev sib txhuam yog 0.05 txog 0.10, uas yog qhov thib peb-qis tshaj ntawm cov khoom siv paub zoo (BAM yog thawj, nrog cov coefficient ntawm kev sib txhuam ntawm 0.02; pob zeb diamond zoo li. carbon yog thib ob-qis tshaj ntawm 0.05).PTFE qhov kev tiv thaiv rau van der Waals rog txhais tau hais tias nws tsuas yog paub qhov chaw uas gecko tsis tuaj yeem lo.Qhov tseeb, PTFE tuaj yeem siv los tiv thaiv cov kab nce toj saum npoo pleev xim nrog cov khoom siv.PTFE yog nplua heev uas kab tsis tuaj yeem tuav tau thiab zoo li poob.Piv txwv li, PTFE yog siv los tiv thaiv ants nce tawm ntawm formicaria.
