Umbhobho wentsimbi ngumngxuma omde wentsimbi, osetyenziswa ngokubanzi njengombhobho wokuthutha ulwelo, olufana neoyile, igesi yendalo, amanzi, igesi, umphunga, njl njl. Ukongeza, ubunzima bukhaphukhaphu xa ukugoba kunye namandla efanayo, ngoko ke ikwasetyenziswa ngokubanzi Ukusetyenziswa ekwenzeni amacandelo oomatshini kunye nezakhiwo zobunjineli.Ikwasetyenziswa ngokuqhelekileyo ukuvelisa izixhobo ezahlukeneyo zesiqhelo, imigqomo, amaqokobhe, njl. Imibhobho yentsimbi edityanisiweyo, ekwaziwa ngokuba yimibhobho edityanisiweyo, eyeyemibhobho yentsimbi ethungelweyo, eyimibhobho yentsimbi eyenziwe ngeepleyiti zentsimbi okanye imitya emva kokuphoswa nokuwelda, ngokubanzi ubude beemitha ezi-6.Inkqubo yokuvelisa umbhobho wensimbi odibeneyo ilula, ukuveliswa kwemveliso kuphezulu, kukho iintlobo ezininzi kunye neenkcukacha, kwaye utyalo-mali kwizixhobo zincinci, kodwa amandla aqhelekileyo angaphantsi kunombhobho wensimbi ongenamthungo.
Ulwahlulo lwemibhobho yentsimbi edityanisiweyo
Ihlelwa ngokwendlela yemveliso
(1) Ngokwenkqubo - umbhobho odityanisiweyo we-arc, umbhobho odityanisiweyo wokuxhathisa (i-frequency ephezulu, i-frequency ephantsi), umbhobho odityanisiweyo wegesi, umbhobho odityanisiweyo womlilo.
(2) Ngokutsho kwe-weld - umthungo odibeneyo umbhobho odibeneyo, umbhobho we-spiral welding
Ihlelwa ngokwemilo yecandelo
(1) Imibhobho yentsimbi enqamlezileyo elula—imibhobho yentsimbi engqukuva, imibhobho yentsimbi eyisikweri, imibhobho yentsimbi embhoxo, imibhobho yentsimbi engunxantathu, imibhobho yentsimbi enehexagonal, imibhobho yentsimbi yerhombus, imibhobho yentsimbi enonxantathu, imibhobho yentsimbi enesiqingatha semicircular, neminye.
(2) Imibhobho yentsimbi enqamlezileyo entsonkothileyo – imibhobho yentsimbi enehexagonal engalinganiyo, imibhobho yentsimbi enepetali ezintlanu emile okweplam, imibhobho yentsimbi eneconvex ephindwe kabini, imibhobho yentsimbi ephindwe kabini, imibhobho yentsimbi emile okwemelon, imibhobho yentsimbi ekhonkokholi, imibhobho yentsimbi egutyungelweyo; imibhobho yentsimbi yecala, njl.
Ngokobunzima bodonga, lunokwahlulwa lube: umbhobho wensimbi obhityileyo kunye nombhobho wensimbi ongqingqwa;
Ngokwemilo yesiphelo, inokwahlulwa ibe yi: umbhobho odibeneyo ojikelezileyo kunye ne-special-shaped (i-square, flat, njl.) ipayipi edibeneyo;
Ukuhlelwa ngokwenjongo
Umbhobho odityanisiweyo ngokubanzi, umbhobho odityanisiweyo ovuthelweyo, umbhobho odityanisiweyo ovuthelweyo, umbhobho odityanisiweyo weoksijini, umbhobho odityanisiweyo wocingo, umbhobho odityanisiweyo we-metric, umbhobho odityanisiweyo, umbhobho wempompo onzulu, umbhobho wemoto, umbhobho wesiguquli, umbhobho wombane odityanisiweyo ocekethekileyo, umbhobho wombane odityanisiweyo okhethekileyo, isikafula. umbhobho kunye ne-spiral welded pipe.
Injongo ephambili
Isetyenziswa kakhulu kubunjineli bokubonelela ngamanzi, kushishino lwepetrochemical, ishishini lemichiza, ishishini lamandla ombane, ukunkcenkceshela kwezolimo, kunye nolwakhiwo lwasezidolophini.Yenye yeemveliso ezingamashumi amabini eziphambili eziveliswe lilizwe lethu.
Isetyenziselwa ukuthutha ulwelo: ukunikezelwa kwamanzi kunye nokukhupha amanzi.Ukuthutha igesi: igesi, umphunga, igesi yepetroleum engamanzi.
Ngeenjongo zesakhiwo: njengemibhobho yokufumba, njengeebhulorho;imibhobho yezikhewu, iindlela, izakhiwo zokwakha, njl.
Imibhobho yentsimbi edibeneyo ihlulwe ibe yi-galvanized kunye ne-non-galvanized ngokonyango lomphezulu wombhobho.Imibhobho yensimbi edibeneyo inokwahlulwa ibe ziindidi ezimbini xa iphuma kwifektri: enye ifakwe kwintambo ekupheleni kombhobho, kwaye enye ayifakwanga ekupheleni kombhobho.Kwimibhobho yensimbi edibeneyo kunye neentambo kwiiphelo zombhobho, ubude bombhobho ngamnye bu-4-9m, kunye neepayipi zensimbi ezidibeneyo ngaphandle kwemicu, ubude bombhobho ngamnye bu-4-12m.
Imibhobho yentsimbi edityanisiweyo yohlulwe ibe yimibhobho yentsimbi ebhityileyo, imibhobho yentsimbi ejiyileyo kunye nemibhobho yentsimbi eqhelekileyo ngokobukhulu bodonga lombhobho.Imibhobho yentsimbi eqhelekileyo iyona nto isetyenziswa kakhulu kwimibhobho yenkqubo, kwaye uxinzelelo lwabo lovavanyo luyi-2.0MPa.Uxinzelelo lovavanyo lombhobho wensimbi oqiniweyo yi-3.0MPa.
Zininzi iindlela zokudityaniswa kwemibhobho yentsimbi edityanisiweyo, kubandakanywa uqhagamshelo oludityanisiweyo, uqhagamshelo lwe-flange kunye ne-welding.Uxhulumaniso lwe-flange lwahlulwe lube ludibaniso lwe-flange olunentambo kunye noqhagamshelwano lwe-welding flange, kwaye indlela ye-welding yahlulwe ibe yi-welding yegesi kunye ne-arc welding.
Ngokuqhelekileyo kusetyenziswa oludityanisiweyo oludityanisiweyo umbhobho uluhlu ukuchazwa: ubukhulu begama 6 ~ 150mm
Imibhobho yentsimbi edityanisiweyo inokwahlulwa ngokweendidi ezintathu ngokwenkqubo yokwenza:
1. Ukuxhathisa kombane umbhobho wentsimbi odityanisiweyo
Ukuxhathisa koMbane welded steel pipe, IsiNgesi igama ERW (Electric resistant welded Pipe), uhlobo weld umthungo ngqo.Ukumelana ne-welding yamkela indlela yoxinzelelo lwe-welding ngaphandle kwentsimbi yokuzalisa.Akukho ukuzaliswa kwamanye amacandelo kwi-weld seam.Impembelelo yesikhumba kunye nefuthe elisondeleyo le-high-frequency current yangoku yenza umgca weplate ufudumale ngokukhawuleza kwiqondo lokushisa kwe-welding, kwaye i-forging yenziwa ngokucinezela i-roller extrusion.Iiwelds zezicubu.
Resistance welded umbhobho yentsimbi inokwahlulwa ibe ngamacandelo amabini: high frequency ukumelana welding HFW (High frequency welding pipe) kunye low frequency resistance welding welding LFW (Low frequency welding).
Imibhobho yentsimbi ye-ERW isetyenziselwa ikakhulu ukuthutha umphunga kunye nezinto ezingamanzi ezifana ne-oyile kunye negesi yendalo, kwaye inokuhlangabezana neemfuno ezahlukeneyo zoxinzelelo oluphezulu noluphantsi.Okwangoku, bakwisikhundla esibalulekileyo kwimibhobho yothutho emhlabeni.
2. Umbhobho wentsimbi odityanisiweyo
Umbhobho wentsimbi odityanisiweyo we-Spiral, igama lesiNgesi elithi SSAW (I-Spiral submerged-arc welding pipe), uhlobo lwe-weld yi-spiral seam.Indlela ye-arc welding ephantsi kwamanzi iyamkelwa, kwaye iileyile zangaphakathi kunye nezangaphandle zidibeneyo.I-arc welding ephantsi kwamanzi (kubandakanywa i-arc surfacing ephantsi kwamanzi kunye ne-electroslag surfacing, njl. njl.) yindlela ebalulekileyo ye-welding, enenzuzo yomgangatho ozinzileyo we-welding, ukuveliswa kwe-welding ephezulu, akukho ukukhanya kwe-arc kunye nomsi omncinci kunye nothuli.
Umbhobho odityanisiweyo we-spiral unobubanzi obukhulu, onokufikelela ngaphezu kwe-3000mm, kwaye ulungele ngakumbi ukuthuthwa kwemibhobho yobubanzi obukhulu kunye nezakhiwo zokwakha.
Ezintathu, umthungo othe tye odityaniswe ngumbhobho wentsimbi
I-Longitudinally Submerged Arc Welded Pipe, igama lesiNgesi yi-LSAW (I-Longitudinally Submerged Arc Welded Pipe), kwaye uhlobo lwe-weld lungumthungo othe tye.Indlela ye-arc welding ephantsi kwamanzi isetyenzisiweyo, kwaye iileyile zangaphakathi kunye nezangaphandle zidibeneyo.Ubukhulu bodonga lombhobho wentsimbi yomthungo othe tye bukhulu kakhulu, kwaye ukusetyenziswa kwawo kuyafana nolombhobho wentsimbi ojikelezayo.
Ngokweenkqubo ezahlukeneyo zokubumba, imibhobho yentsimbi edityanisiweyo ethe tye inokwahlulwa ibe ngamacandelo amabini: UOE (Uing kunye ne-Oing yokwenza umbhobho) kunye ne-JCOE (J-ing, C-ing kunye ne-O-ing pipe).Indlela yokwenza i-UOE (ukwenza u-U, ukwakheka kwe-O, ukwandiswa kwedayamitha ye-E), indlela yokwenza i-JCOE (ipleyiti yentsimbi icinezelwe kwimilo engu-J, emva koko icinezelwe kwimilo engu-C kunye ne-O ngokulandelelana, emva koko yandiswa).
Kufuneka kuqatshelwe ukuba inkqubo ye-arc welding ephantsi kwamanzi (SAW) luhlobo lwe-welding yombane yokudibanisa (i-EFW Electric Fusion Welded Pipe), edibanisa isinyithi ngokufudumeza isinyithi phakathi kwe-electrode enye okanye ezininzi ezisetyenziswayo kunye nomsebenzi.Enye yeenkqubo apho i-arc inyibilika ngokupheleleyo isinyithi kunye nezinto zokuzalisa ngaphandle koxinzelelo, kwaye inxalenye yentsimbi yokuzalisa ivela kwi-electrodes.
