Ubuciko beinsimbi yensimbi yeldingDinga inhlanganisela evumelanayo yekhono, ukunemba kanye nezinto ezisezingeni eliphakeme ukuqinisekisa ubuqotho obuhle kakhulu bezicelo ezahlukahlukene. Phakathi kwezinhlobo eziningi zepayipi, uSpiral Welded Carbon Mip, njenge-X42 SSAW PIPE, uyathandwa ngamandla awo aphakeme, ukuqina kanye nokusebenza kwezindleko. Kule bhulogi, sizohlola ukubaluleka kwamapayipi e-carbon wensimbi enomoya enqubweni yensimbi ye-welding yensimbi, ukuwakhipha kwinqubo yawo yokukhiqiza, izinzuzo nezindawo zohlelo lokusebenza.

I-FF: Insimbi ebulewe ngokuphelele equkethe izinto ezibophayo ze-nitrogen ngamanani anele ukubopha i-nitrogen etholakalayo (isib
b. Inani eliphakeme le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kukhombisa okuqukethwe okuphelele kwe-AL ye-AL ye-0,020% ngesilinganiso esingu-2: 1, noma uma kungenjalo ezinye izinto ezibophayo ze-N zikhona. Izinto ezibophayo ze-N-Bonding zizoqoshwa kudokhumenti lokuhlola.

Inqubo Yokukhiqiza

Kuvunguza ipayipi lelded, eyaziwa nangokuthi i-SSAW (Spiral Rollged ARDC Welded) ipayipi, akhiqizwa kusetshenziswa amasu akwa-Welding we-ARC. Inqubo iqala ngokwelashwa kwemingcele yomucu wensimbi ehlanganisiwe bese ugoba umucu ube yisimo sokulumba. I-Welding ye-arc ethonywe ngokuzenzakalela isetshenziselwa ukujoyina imiphetho yemichilo ndawonye, idale i-wald eqhubekayo lapho ubude bepayipi. Le ndlela iqinisekisa ukuthi ukuhlangana kuqinile futhi kuhlala isikhathi eside ngenkathi kunciphisa iziphambeko nokugcina ubuqotho bezinhlekelele.

Izinzuzo ze-Spiral Welded Carbon Insimbi Pipe

1. Amandla nokuqina:Kuvunguza i-welded carbon steel pipeYaziwa ngamandla ayo aphezulu nokuqina, okwenza kube lula ukuthola izinhlelo zokusebenza ezidinga ukumelana nengcindezelo ephezulu nokusebenza kwesikhathi eside.

2. Ukusebenza kwezindleko: Lawa mapayipi anikela ngesisombululo esisebenza ngempumelelo ngenxa yenqubo yawo yokukhiqiza, izindleko eziphansi ezibonakalayo ezibonakalayo, kanye nezidingo ezincishisiwe ezibonakalayo, futhi zinciphise izidingo zabasebenzi uma ziqhathaniswa nezinye izinhlobo zamapayipi.

I-3. Ukuguquguquka okuguquguqukayo

4. Ukunemba okuyisisekelo: Inqubo yokwakha i-Spiral ingalawula kahle usayizi nobukhulu bepayipi, ukuqinisekisa ukunemba nokufana kokukhiqizwa.

Izindawo zohlelo lokusebenza

1. Imboni kawoyela neyemvelo yemvelo: Amapayipi e-carbon e-welded carbon asetshenziswa kabanzi embonini kawoyela kanye negesi yemvelo, ikakhulukazi ezokuhamba kawoyela ongahluziwe, imikhiqizo yemvelo kanye nemikhiqizo yemvelo kanye nemikhiqizo ye-petroleum. Amandla abo kanye namandla abo okubekezelela izindawo eziphakeme zengcindezelo zizenza zilungele amapayipi amabanga amade.

3 Ukuqina kwabo kanye nokumelana kwabo nezinto zangaphandle kubenza bathembeke kulezi zinhlelo.

Ekuphetheni

Kuvunguza i-welded carbon ipayipi, njengeX42 ssaw ipayipi, iguqule inqubo ye-welding yensimbi yensimbi, ilethe izinzuzo eziningi kwizimboni ezahlukahlukene. Amandla abo, ukuqina, ukusebenza kwezindleko nokunemba okubucayi kuqinisekisa ubuqotho obuhle ngezinhlobo ezahlukahlukene. Amandla okubekezelela ukucindezelwa okwedlulele, amazinga okushisa kanye nezindawo ezilimazayo zenza kube ngcono ukuhanjiswa kwamafutha nokuhanjiswa kwegesi kanye neminye imikhakha yezimboni. Ngakho-ke, uma kukhulunywa ngensimbi ye-welding yensimbi yensimbi, ukusetshenziswa kwamapayipi e-carbon we-weldive ared carbon kuhlala kuyikhambi elithembekile nelisebenzayo lokuqinisekisa ingqalasizinda ehlala njalo nenempilo ende.

Ukuhlolwa kweHydrostatic

Ubude bepayipi ngalinye buzovivinywa ngumenzi ngengcindezi ye-hydrostatic ezokhiqiza odongeni lwamapayipi ingcindezi engaphansi kwamandla ka-60% acacisiwe amancane okushisa avumayo ekushiseni kwegumbi. Ingcindezi izonqunywa yi-equation elandelayo:
P = 2st / d

Ukuhlukahluka okuvumelekile ezinsimbi nasezilinganiso

Ubude bepayipi ngalinye buzosindwa ngokwehlukana futhi isisindo salo ngeke bahlukane ngaphezu kwe-10% ngaphezulu noma ngo-5.5% ngaphansi kwesisindo sayo sethiyori, kubalwa kusetshenziswa ubude baso kanye nesisindo sayo ngeyunithi yayo ngayinye ubude
Ububanzi bangaphandle ngeke buhluka kakhulu kune- ± 1% kusuka kububanzi obucacisiwe be-off
Ubukhulu bodonga nganoma yiliphi iphuzu ngeke bungabi ngaphezu kwe-12,5% ngaphansi kobukhulu bedonga olubekiwe
