Umbhobho weThermoplastic owomeleziweyo
Umbhobho weThermoplastic owomeleziweyo
Umbhobho we-thermoplastic oqinisiweyo (RTP) ligama eliqhelekileyo elibhekiselele kwifayibha eyenziwe yamandla aphezulu ethembekileyo (efana neglasi, iaramid okanye ikhabhoni)
iimpawu zayo eziphambili kukumelana nokukhula / ukunyamezela koxinzelelo oluphezulu kunye nokugcina ukuguquguquka kwangaxeshanye, kunokwenziwa kwifom ye-reel (umbhobho oqhubekayo), kunye nobude obusuka kwishumi leemitha ukuya kwiikhilomitha kwi-reel enye.
Kwiminyaka embalwa edlulileyo olu hlobo lombhobho luye lwavunywa njengesisombululo esiqhelekileyo kwintsimbi ye-oilfield flowline applications yinkampani ezithile zeoyile kunye nabaqhubi. Inzuzo yalo mbhobho ikwalixesha layo lofakelo olukhawulezayo kakhulu xa kuthelekiswa nombhobho wentsimbi xa kuqwalaselwa ixesha lokuwelda njengezantya zomndilili ukuya kuthi ga kwi-1,000 m (3,281 ft)/ngosuku zifikelelwe ngokufaka i-RTP kumphezulu womhlaba.
Imveliso yeRTP Techniques
Umbhobho we-thermoplastic oqinisiweyo uqukethe i-3 yesiseko esisisiseko: i-internal thermoplastic liner, i-fiber eqhubekayo yokuqinisa i-helically ehlanganiswe kumbhobho, kunye nejacket ye-thermoplastic yangaphandle. I-liner isebenza njenge-bladder, i-fiber reinforcement inika amandla, kwaye ibhatyi ikhusela iifayili ezithwala umthwalo.
Iingenelo
Ukumelana noxinzelelo oluphezulu: Ukuxhatshazwa koxinzelelo oluphezulu lwenkqubo yi-50 MPa, amaxesha angama-40 emibhobho yeplastiki.
Ukumelana nobushushu obuphezulu: Ubushushu obuphezulu bokusebenza kwenkqubo yi-130 ℃, i-60 ℃ ephezulu kunemibhobho yeplastiki.
Ubomi obude: amaxesha ama-6 emibhobho yetsimbi, amaxesha ama-2 emibhobho yeplastiki.
Ukumelana nokuCorrosion: Ayinamhlwa kunye nokusingqongileyo.
Ubunzima bodonga: Ubukhulu bodonga yi-1/4 yemibhobho yeplastiki, iphucula i-30% yezinga lokuhamba.
Ikhaphukhaphu: 40% ubude beeyunithi zemibhobho yeplastiki.
I-Non-scale: Udonga lwangaphakathi luhamba kakuhle kwaye alunamlinganiselo, kwaye isantya sokuhamba sihamba ngamaxesha angama-2 emibhobho yensimbi.
Akukho ngxolo: Ukukhuhlana okuphantsi, ukuxinana kwezinto eziphantsi, akukho ngxolo emanzini aqukuqelayo.
Amalungu awomeleleyo: Indawo ephindwe kabini yeglasi yefayibha kumalungu, isokethi enyibilikayo eshushu, ayisoze ivuze.
Iindleko eziphantsi: Ngokusondeleyo kwiindleko zemibhobho yensimbi kunye ne-40% ephantsi kunemibhobho yeplastiki.
