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 zalo?

1) Iyini impahla yepayipi yensimbi ye-carbon?

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.
