Reinforced thermoplastic pipe (RTP) ishoko rekare rinoreva yakavimbika yakakwirira simba rekugadzira faibha (senge girazi, aramid kana kabhoni), yakatanga kugadzirwa mukutanga kwema1990s naWavin Repox, Akzo Nobel uye naTubes d'Aquitaine wekuFrance, uyo. yakagadzira mapaipi ekutanga akasimbiswa nesynthetic fiber kutsiva epakati kudzvanywa simbi pombi mukupindura kuri kukura kudiwa kweasina-kuora conduits kuti ashandiswe muindasitiri yemafuta negasi ekumahombekombe, kunyanya kuMiddle East. Kazhinji, zvinhu zvinoshandiswa pakuvaka pombi inogona kunge iri Polyethylene (PE), Polyamide-11 kana PVDF uye inogona kusimbiswa neAramid kana Polyester fiber kunyangwe mamwe masanganiswa achishandiswa.
Munguva pfupi yapfuura tekinoroji yekugadzira pombi yakadai, kusanganisira kushambadzira, inosara nemakambani mashoma akakosha, imwe yacho Pipelife neSoluforce uko inowanikwa mumakoiri anosvika 400 m (1,312 ft) kureba.Mapombi aya anowanikwa mukumanikidzwa ratings kubva pa30 kusvika 90 bar (3 kusvika 9 MPa; 435 kusvika 1,305 psi).Kwemakore mashoma apfuura rudzi urwu rwepombi rwakabvumwa seimwe yakajairwa imwe mhinduro kune simbi yeoilfield flowline application nemamwe makambani emafuta nevashandisi.Kubatsira kukuru kwepombi iyi zvakare inokurumidza kugadzika nguva kana ichienzaniswa nenyere dzesimbi kana uchifunga nezvenguva yewelding seavhareji inomhanya kusvika 1,000 m (3,281 ft) / zuva yasvikwa kuisa RTP muvhu pevhu.
Kunyanya, pombi inopa rubatsiro kune zvikumbiro apo simbi inogona kuputika nekuda kwekuora uye nguva yekuisa inyaya.
PTFE inonzi thermoplastic polymer, iri chena yakasimba patembiricha yemumba, ine density inoita 2200 kg/m3.Zvinoenderana neChemours, kunyungudika kwayo i600 K (327 °C; 620 °F).[19]Inochengetedza simba repamusoro, kuomarara uye kuzvigadzika patembiricha yakaderera kusvika pa5 K (−268.15 °C; -450.67 °F), uye kuchinjika zvakanaka patembiricha iri pamusoro pe194 K (-79 °C; -110 °F).PTFE inowana zvivakwa zvayo kubva paaggregate mhedzisiro yecarbon-fluorine bond, sezvinoita ese mafluorocarbons.Iwo ega makemikoro anozivikanwa kukanganisa aya kabhoni-fluorine zvisungo simbi dzinoshanda zvakanyanya senge alkali simbi, uye pakupisa kwepamusoro zvakare simbi sealuminium nemagnesium, uye fluorinating agents senge xenon difluoride uye cobalt (III) fluoride.
The coefficient of friction of plastics inowanzopimwa nesimbi yakakwenenzverwa.PTFE's coefficient of friction is 0.05 to 0.10, inova yechitatu-yakaderera pane chero chinhu chakasimba chinozivikanwa chinhu (BAM iri yekutanga, ine coefficient of friction of 0.02; diamond-like kabhoni iri yechipiri-yakaderera pa 0.05).Kuramba kwePTFE kumauto evan der Waals zvinoreva kuti ndiyo chete nzvimbo inozivikanwa isingagone kunamira negwara.Muchokwadi, PTFE inogona kushandiswa kudzivirira zvipembenene kukwira kumusoro kwakapendwa nezvinhu.PTFE inotsvedza zvekuti zvipembenene hazvigone kubata uye zvinowanzodonha.Semuenzaniso, PTFE inoshandiswa kudzivirira majuru kukwira kunze kwe formicaria.
