Ingabe ipayipi lensimbi ye-carbon liyipayipi lensimbi elishiselwe?

Ipayipi lensimbi ye-Carbon aliyona ipayipi lensimbi elishiselwe.Ipayipi lensimbi ye-Carbon libhekisela entweni ethile yepayipi lensimbi insimbi ye-carbon, ebhekisela ku-iron-carbon alloy enokuqukethwe kwekhabhoni Wc ngaphansi kuka-2.11%.Ngaphezu kwe-carbon, ngokuvamile iqukethe inani elincane le-silicon, i-manganese, i-phosphorus, isulfure nokunye ukungcola.nezinye izakhi ezisele.Ngaphezu kwalokho, leli payipi lensimbi ye-carbon linezinhlelo eziningi zokusebenza, ikakhulukazi ezisetshenziselwa ukwakhiwa, amabhuloho, izitimela, izimoto, imikhumbi kanye nezimboni ezihlukahlukene zokukhiqiza imishini.

Amapayipi ensimbi ekhabhoni angahlukaniswa abe amapayipi e-carbon steel ashiselwe namapayipi angenamthungo ensimbi ngokwenqubo yokukhiqiza.

Amapayipi ensimbi ashiselwe ngekhabhoni angahlukaniswa abe yizinhlobo ezintathu: amapayipi ensimbi afakwe umthungo oqondile angaphansi kwe-arc, amapayipi ensimbi ashiselwe avunguzayo, kanye namapayipi ensimbi ashiselwe imvamisa ephezulu aqondile ngokwendlela yokwenza umthungo wokushisela.
Ipayipi elishiselwe iLongitudinal: I-weld isemgqeni oqondile, ngakho-ke ibizwa ngokuthi i-straight seam welded pipe.
Ipayipi elishiselwe elivunguzayo: I-weld seam isesimweni esisango, esibizwa nge-spiral welding.

Izindlela ezintathu zokushisela zinezinzuzo zazo kanye nokubi, futhi iyiphi okufanele isetshenziswe incike ezidingweni zokuklama.Ipayipi lensimbi elishiselwe i-Carbon steel welded steel lingasetshenziswa emikhakheni eminingi, njengamaphrojekthi wokuphakelwa kwamanzi kanye ne-drainage, amaphrojekthi wokunqwabelanisa, amapayipi okukhucululwa kwendle, ukudluliswa kukawoyela negesi, izinsika zesakhiwo namanye amaphrojekthi.Indlela yamanje yokushisela ye-carbon steel welded steel pipe iwukushisela i-arc enezinhlangothi ezimbili.Le ndlela yokushisela inokusebenza kahle okuphezulu, ikhwalithi ephezulu ye-weld kanye nobuso obushelelezi.

Indlela yokukhiqiza ipayipi yensimbi engenamthungo:

Amapayipi ensimbi ye-Carbon angenamthungo ahlukaniswe abe izinhlobo ezimbili: amapayipi ensimbi angenamthungo ashisayo (akhishiwe) kanye namapayipi ensimbi adonswa ngokubanda (agoqiwe) angenamthungo ngenxa yezinqubo zawo ezihlukene zokukhiqiza.Amashubhu abandayo adonswe (agoqiwe) ahlukaniswe abe izinhlobo ezimbili: amashubhu ayindilinga namashubhu amise okukhethekile.

1. Ipayipi lensimbi eligoqiwe elishisayo (elikhishiwe) le-carbon steel engenamthungo: ishubhu billet → ukufudumeza → ukubhoboza → rolling cross rolling noma extrusion → ukukhishwa kweshubhu → ukusika (noma ukunciphisa) → ukupholisa → ukuqondisa → Ukuhlola ukucindezela kwamanzi ( noma ukutholwa kwamaphutha) → ukumaka → isitoreji

Impahla eluhlaza yokugingqa ipayipi lensimbi yensimbi engenamthungo yi-tube billet eyindilinga, futhi umbungu weshubhu eliyindilinga kufanele usikwe ngomshini wokusika ukuze ukhulise amabhilidi anobude obungangemitha elingu-1, bese uyiswa esithandweni ngebhande lokuthutha.I-Billet ifakwa esithandweni ukuze kushiswe, izinga lokushisa lingaba ngu-1200 degrees Celsius.Uphethiloli yi-hydrogen noma i-acetylene.Ukulawulwa kwezinga lokushisa esithandweni kuyinkinga eyinhloko.Ngemuva kokuthi ishubhu eliyindilinga seliphumile esithandweni, kufanele libhobozwe ngombhobho wokucindezela.Ngokuvamile, umbhobozi ovame kakhulu umbhobozi we-cone roll.Lolu hlobo lokubhoboza lusebenza kahle kakhulu ekukhiqizeni, ikhwalithi yomkhiqizo omuhle, ukunwetshwa okukhulu kobubanzi bokubhoboza, futhi lungagqoka izinhlobo zensimbi ezihlukahlukene.Ngemuva kokubhoboza, i-tube billet eyindilinga igoqeka ngokulandelana, igoqwe ngokuqhubekayo noma ikhishwe ngemiqulu emithathu.Ngemuva kwe-extrusion, i-tube kufanele ikhishwe ukuze ilinganiswe.Ukulinganisa ngezimbobo ze-rotary cone ezinesivinini esikhulu ku-billet ukuze kwakheke ishubhu.Ububanzi bangaphakathi bombhobho wensimbi bunqunywa ubude be-diameter yangaphandle ye-drill bit yomshini wokulinganisa.Ngemva kokuba ipayipi lensimbi lilinganiselwe, lingena embhoshongweni wokupholisa futhi lipholiswe ngokufafaza amanzi.Ngemva kokuba ipayipi lensimbi selipholile, lizoqondiswa.Ngemva kokuqondisa, ipayipi lensimbi lithunyelwa kumtshina wensimbi (noma ukuhlolwa kwe-hydraulic) ngebhande lokudlulisa ukuze kutholwe amaphutha angaphakathi.Uma kukhona ukuqhekeka, ama-bubbles nezinye izinkinga ngaphakathi kwepayipi lensimbi, zizotholwa.Ngemuva kokuhlolwa kwekhwalithi yamapayipi ensimbi, ukukhetha okuqinile okwenziwa ngesandla kuyadingeka.Ngemuva kokuhlolwa kwekhwalithi yepayipi yensimbi, penda inombolo ye-serial, ukucaciswa, inombolo ye-batch yokukhiqiza, njll. ngopende.Futhi waphakanyiselwa endlini yokugcina izimpahla by crane.

2. Ipayipi lensimbi elibandayo elidonsayo (eligoqiwe) le-carbon steel engenamthungo: ishubhu eliyindilinga alinalutho→ishisa→ukubhoboza→isihloko→i-annealing→ukugcoba→ukugcoba→ukugcoba (i-copper plating)→umdwebo obandayo onama-multi-pass (ukuginqika okubandayo)→ithubhu elingenalutho→ukwelapha ukushisa→Ukuqondisa →ukuhlolwa kwe-hydrostatic (ukutholwa kwamaphutha)→ukumaka→indawo yokugcina izinto
