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 ekhabhoni angenamthungo ahlukaniswe abe izinhlobo ezimbili: amapayipi ensimbi asongwe ngokushisayo (akhishiwe) namapayipi ensimbi adonswa ngokubanda (agingqwe) 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
