Ngenxa yentuthuko eqhubekayo yokuya emadolobheni, izinto zokwakha emakethe yezinto zokwakha zivela ngokungapheli.Nakuba lezi zinto zivamile ekuphileni kwethu kwansuku zonke, abantu abangajwayele ukugijima emakethe yezinto zokwakha bangase bangazi amapayipi ensimbi ye-carbon.Ngeke siqonde izinzuzo nezingozi zayo, futhi singase singakunaki nokuba khona kwayo.Okulandelayo, namuhla ngizokuchazela ukuthi iyiphi impahla eyipayipi yensimbi ye-carbon?Yiziphi izinzuzo nezingozi zayo?

1) Iyini impahla ye-carbon steel pipe?

Insimbi ye-carbon ikakhulukazi ibhekisela ensimbi izakhiwo zayo zomshini zincike kokuqukethwe kwekhabhoni ensimbi.Ngokuvamile, inani elikhulu lezakhi ze-alloying ayengezwa, futhi ngezinye izikhathi libizwa ngokuthi i-carbon steel evamile noma i-carbon steel.I-Carbon steel, eyaziwa nangokuthi i-carbon steel, isho ingxubevange ye-iron-carbon enokuqukethwe kwekhabhoni okungaphansi kuka-2% weWC.Ngaphezu kwe-carbon, i-carbon steel ngokuvamile iqukethe amanani amancane e-silicon, i-manganese, isulfure, ne-phosphorus.Ngokuvamile, ukuphakama kwekhabhoni yensimbi yensimbi, ubulukhuni bukhulu, amandla aphezulu, kodwa ipulasitiki iyancipha.

Amapayipi ensimbi ekhabhoni (cs pipe) zenziwe nge-carbon steel ingots noma insimbi eyindilinga eqinile ngokubhoboza amashubhu e-capillary, bese kwenziwa ngokuginqika okushisayo, ukugoqa okubandayo noma umdwebo obandayo.Ipayipi lensimbi ye-Carbon lidlala indima ebalulekile embonini yamapayipi ensimbi yezwe lami.

2) Yiziphi izinzuzo kanye nokubi amapayipi carbon steel?

Inzuzo:

1. Ipayipi lensimbi ye-Carbon lingathola ubulukhuni obuphakeme kanye nokumelana nokugqoka okungcono ngemva kokwelashwa kokushisa.
2. Ukuqina kwepayipi lensimbi ye-carbon esimweni sokuthunjwa kulinganiselwe kakhulu, futhi kunokusebenza okuhle.
3. Izinto zokusetshenziswa zamapayipi ensimbi ye-carbon zivame kakhulu, kulula ukuzithola, futhi izindleko zokukhiqiza ziphansi kakhulu.

Ububi:

1. Ukuqina okushisayo kwepayipi yensimbi ye-carbon kuyoba mpofu, ngoba lapho izinga lokushisa lokusebenza kwethuluzi likhulu kunama-degree angu-200, ubunzima bayo nokumelana nokugqoka kuzokwehla kakhulu.
2. Ukuqina kwe-carbon steel kuphansi kakhulu.Ububanzi bensimbi eqiniswe ngokuphelele ngokuvamile buba ngu-15-18 mm lapho amanzi ecinywa, kuyilapho ububanzi noma ukujiya kwensimbi ye-carbon cishe ku-6 mm kuphela uma ingacinywa, ngakho-ke kuyoba lula ukukhubaza nokuqhekeka.

3) Yiziphi izigaba ze-carbon steel materials?

1. Ngokusho kwesicelo, i-carbon steel ingahlukaniswa ngezigaba ezintathu: insimbi ye-carbon structural, insimbi yensimbi ye-carbon kanye nensimbi yesakhiwo yokusika mahhala.
2. Ngokwendlela yokuncibilikisa, i-carbon steel ingahlukaniswa ngezigaba ezintathu: insimbi evulekile yeziko, insimbi yokuguqula kanye nensimbi yesithando somlilo.
3. Ngokwendlela ye-deoxidation, i-carbon steel ingahlukaniswa ibe yinsimbi ebilayo, insimbi ebulewe, insimbi ebulewe kancane kanye nensimbi ekhethekile ebulewe, emelwe amakhodi F, Z, b, kanye ne-TZ ngokulandelana.
4. Ngokusho kokuqukethwe kwekhabhoni, i-carbon steel ingahlukaniswa ngezigaba ezintathu: insimbi ephansi ye-carbon, i-medium carbon steel kanye ne-high carbon steel.
5. Ngokusho kokuqukethwe kwesulfure ne-phosphorus, i-carbon steel ingahlukaniswa ibe yi-carbon steel evamile (okuqukethwe kwe-phosphorus nesulfure kuyoba ngaphezulu), insimbi yekhwalithi ephezulu ye-carbon (okuqukethwe kwe-phosphorus nesulfure kuyoba phansi), okuphezulu -insimbi yekhwalithi (equkethe i-phosphorus nesibabule okuqukethwe okuphansi) kanye nensimbi yekhwalithi ephezulu kakhulu.

4) Yiziphi izigaba zamapayipi ensimbi ye-carbon?

Amapayipi ensimbi ekhabhoni angahlukaniswa abe amapayipi angenamthungo, amapayipi ensimbi omthungo oqondile, amapayipi asongezelayo, amapayipi ensimbi ashiselwe imvamisa ephezulu, njll.

Ipayipi lensimbi eligoqiwe elingenamthungo (elikhishiwe): ishubhu eliyindilinga billet → ukushisisa → ukubhoboza → ukugoqeka okuphambanayo kwama-roll amathathu, ukugoqeka okuqhubekayo noma ukukhishwa → ukuhlubula → ukusika (noma ukunciphisa) → ukupholisa → ukuqondisa → ukuhlola okuqhutshwa ngamanzi (noma ukutholwa kwamaphutha) → ukumaka → isitoreji

Ipayipi lensimbi elibandayo elidonsayo (eligoqiwe) le-carbon steel elingenamthungo: ishubhu eliyindilinga alinalutho → ukushisa→ukubhoboza→isihloko→i-annealing→i-pickling→i-oil (i-copper plating)→umdwebo obandayo onama-multi-pass (ukuginqika okubandayo)→ithubhu elingenalutho→ukwelapha ukushisa→ukuqondisa →I-Hydrostatic ukuhlola (ukutholwa kwamaphutha)→Maka→Isitoreji

Amapayipi ensimbi engenamthungo e-Carbon steel ahlukaniswe abe izinhlobo ezimbili: amapayipi ensimbi ashisayo agingqiwe (extruded) namapayipi ensimbi adonswa ngokubanda (agingqelwe) angenamthungo ngenxa yezinqubo zawo ezihlukene zokukhiqiza.Amashubhu abandayo adonswe (agoqiwe) ahlukaniswe abe izinhlobo ezimbili: amashubhu ayindilinga namashubhu amise okukhethekile.
