Umbhobho wensimbi odibeneyo wenziwa ngezinto ezimbini (okanye ngaphezulu) ezidityanisiweyo zibe yinye ngokusebenzisa iindlela ezithile zobuchwepheshe ukuze ube neempawu ezibanzi Umbhobho wentsimbi omtsha weSex.Ukususela kwiminyaka yoo-1960, iJapan, iUnited States, iJamani, iUnited Kingdom kunye namanye amazwe ancamathele ukubaluleka okukhulu kuphuhliso lwemibhobho yentsimbi edityanisiweyo, iimveliso zemibhobho yentsimbi edibeneyo kumandla, ukwakhiwa kweenqanawa, iikhemikhali, i-petroleum kunye noomatshini kunye namanye amasimi. esetyenzisiweyo.
Umbhobho wensimbi odibeneyo wenziwa ngezinto ezimbini (okanye ngaphezulu) ezidityanisiweyo zibe yinye ngokusebenzisa iindlela ezithile zobuchwepheshe ukuze ube neempawu ezibanzi.
Ukusukela ngeminyaka yoo-1960, iJapan, iUnited States, iJamani, iUnited Kingdom kunye namanye amazwe ancamathele ukubaluleka okukhulu kuphuhliso lwentsimbi edityanisiweyo.PTFE umbhobho onemigca, iimveliso zemibhobho yensimbi edibeneyo kumandla, ukwakha iinqanawa, iikhemikhali, i-petroleum kunye noomatshini kunye nezinye iindawo zisetyenziswe ngokubanzi.Itekhnoloji yokucubungula ityhubhu yentsimbi ehlanganisiweyo ikakhulu ibandakanya ukuqengqeleka, ukuphosa, ukukhupha, ukugalela, ukuwelda njalo njalo.
- 1.Uluhlu lwesicelo sombhobho wensimbi odibeneyo
Imowudi yokudibanisa yeentlobo ezimbini zezixhobo zomaleko omnye wentsimbi edibeneyo yombhobho odibeneyo uxhomekeke ngokupheleleyo kwiimfuno zesicelo kunye neempawu zokusingqongileyo.Umbhobho wensimbi osisiseko unamandla amakhulu kunye nokuqina, ixabiso eliphantsi kunye nokusebenza kakuhle kwenkqubo.Umbhobho wensimbi ogqunyiweyo uya kuba nobunzima obuphezulu kwaye ube nokukwazi ukuxhathisa i-corrosion ye-medium medium.Lo maleko unokuba kuluhlu lwangaphakathi lombhobho wentsimbi edibeneyo (umbhobho odibeneyo wangaphakathi) okanye kuluhlu lwangaphandle (umbhobho odibeneyo ongaphandle). umbhobho wequla, ibhoyila, isitshisi senkunkuma esinetyhubhu eninzi, umbhobho wokutshintshiselana kobushushu, ngokuxhathisa ukunxiba, ulwakhiwo lokumelana nomhlwa kunye netyhubhu eninzi kunye nombhobho wokuhombisa wokwakha, njl. umbhobho uya kwandiswa kwiindawo zesicelo ezibanzi.
- 2. Indlela yokuvelisa yeumbhobho wentsimbi odibeneyo
Imibhobho yentsimbi ehlanganisiweyo inokwahlulwa ibe ziindidi ezimbini, i-bimetallic kunye ne-double-layer, ngokwemeko edibeneyo yokunxibelelana konxibelelwano lweentlobo ezimbini zemibhobho yentsimbi.Umbhobho wensimbi odibeneyo kunye nojongano loqhagamshelwano lwangaphakathi kunye nangaphandle umaleko odityaniswe kwisidanga se-metallurgical bonding ubizwa ngokuba ngumbhobho we-bimetallic, ngelixa ujongano loqhagamshelwano lwangaphakathi nangaphandle lufikelela kuphela kuqhagamshelo lomatshini, kunye nombhobho wentsimbi odibeneyo kunye noluhlu lwecandelo longitudinal kunye nomaleko ohlulwe ngokukhululekileyo. ibizwa ngokuba ngumbhobho ophindwe kabini.Kukho iindlela ezininzi ezahlukeneyo zenkqubo yokuvelisa imibhobho yensimbi edibeneyo, nganye ineempawu zayo kunye nobubanzi besicelo.
- 2.1 Inkqubo yokusebenza eshushu
Kule ndlela, i-carbon steel billet eqhelekileyo isetyenziswa njengentsimbi esisiseko yangaphandle, umngxuma ophakathi ugrunjwa, kwaye insimbi engenasici okanye i-nickel alloy rod isetyenziswa njengomaleko wangaphakathi.Isiqinisekiso sangaphandle seempawu ezibonakalayo zombhobho odibeneyo, iimfuno zombhobho wangaphakathi, xa ibha kunye nomphezulu webillet emva komphezulu womngxuma ongaphakathi ucocekile, uya kuba nebar efakelweyo umngxuma webillet wombhobho, ukutywina itywina iziphelo zebillet yetyhubhu, sebenzisa inqanaba. yecoil ephantsi yokwenziwa kwe-confrequency ukulawula ukufudumeza, emva kokufudunyezwa ukuseta iqondo lobushushu, kwi-1 600 t punch eshushu kumatshini wokungqiya we-hydraulic nkqo, ibhayibhile yombhobho kwimo ejikelezayo yokugqobhoza kunye ne-axial ecinezelekileyo yokulinganisa isangqa sokugqobhoza, emva kwe-thermal perforated tube billet, ibha. kunye nesiseko semathiriyeli yokudibanisa i-metallurgical.Le nkqubo isetyenziswe nguTubacex, inkampani yaseSpain yepayipi yensimbi ekhutshweyo, ukuvelisa iipayipi zensimbi ezidibeneyo kunye needamitha zangaphandle ze-60 · 3 kunye ne-219 · Imm.Ubukhulu bombhobho we-lining resistant corrosion ngokuqhelekileyo bu-10% ukuya kwi-0% yobukhulu obupheleleyo bombhobho odibeneyo odibeneyo, ngokuqhelekileyo phakathi kwe-2 cm kunye ne-1 cm ubuncinane.
- 2.2 Indlela yokudibanisa ipleyiti yentsimbi
Le ndlela ingasetyenziselwa ukwenza imibhobho yentsimbi edityanisiweyo kwimibhobho yokuhambisa i-oyile nerhasi enobubanzi obungaphezulu kwe-300mm.Inkqubo yokuhamba kombhobho wensimbi odibeneyo oveliswa yile ndlela ngolu hlobo lulandelayo: i-longitudinal seam welding - umbhobho wokwandisa - unyango lobushushu lweshiti yensimbi i-jo eyenza i-billet.
- 2.3 Inkqubo ebandayo yokusasazwa kwe-annealing
Iibhilidi zetyhubhu zezixhobo ezahlukeneyo zenziwa kwiibhubhu ezingenamthungo ezibandayo okanye ezibandayo.Ibhanti elincinane elinyibilikayo elisezantsi elinyibilikayo lijikelezwe kwicala elingaphandle lomaleko wangaphakathi weebhilithi zetyhubhu.Emva komzobo obandayo, i-annealing yokusasazwa kobushushu obuphezulu iyenziwa.Isici sensimbi edibeneyo efakwe umbhobho owenziwe yile nkqubo kukuba umda odibeneyo ubonakala ngokucacileyo kwaye unjalo.Ngenxa yokongezwa komgangatho ophantsi wokunyibilika wesinyithi phakathi kweendlela ezimbini zokuhlangana, amandla ayo okubopha aphezulu kakhulu, adla ngokuba mkhulu kune-300MPao.Indawo ephantsi yokunyibilika kwezinto zensimbi ye-gasket idla ngokuba yi-Ni - P ingxubevange, kwaye iqondo lobushushu layo liyancipha ngokunyuka komxholo we-P. Enye i-gaskets yi-B (1, 4Wt%), i-Si (ukuya kwi-9Wt%), i-cr (ukuya kuthi ga kwi-30Wt%) intsimbi - okanye i-alloys esekelwe kwi-ni.Indawo yokunyibilika kwezinto ze-gasket kufuneka ibe ngaphantsi kwe-tube yesiseko yangaphandle kunye nombhobho wangaphakathi.I-tube yensimbi edibeneyo eveliswa yile nkqubo inokumelana nokubumba ukugoba, kwaye ukuchaneka kwayo kwe-dimensional kunye nomgangatho womhlaba unokuhlangabezana neemfuno eziqhelekileyo.
