Lapho uhlangabezana ne-oda elidinga ukukhiqizwa, ngokuvamile kuyadingeka ukulinda ukuhlelwa kokukhiqiza, okuhluka kusuka ezinsukwini ezi-3-5 kuya ezinsukwini ezingama-30-45, futhi usuku lokulethwa kufanele luqinisekiswe nekhasimende ukuze bobabili abathintekayo bakwazi ukufinyelela isivumelwano.

Inqubo yokukhiqiza amapayipi ensimbi engenamthungo ikakhulukazi ihlanganisa lezi zinyathelo ezibalulekile ezilandelayo:

1. Ukulungiswa kwe-billet
Izinto zokusetshenziswa zamapayipi ensimbi angenamthungo ziyinsimbi eyindilinga noma ama-ingots, ngokuvamile insimbi yekhwalithi ephezulu yekhabhoni noma insimbi ye-alloy ephansi. I-billet iyahlanzwa, indawo yayo ihlolwe ukuthi ayinamaphutha, futhi inqunywe ubude obudingekayo.

2. Ukushisisa
I-billet ithunyelwa esithandweni sokushisa ukuze kushiswe, ngokuvamile ekushiseni okungaba ngu-1200 ℃. Ukushisa okufanayo kufanele kuqinisekiswe ngesikhathi sokushisa ukuze inqubo yokubhoboza elandelayo iqhubeke kahle.

3. Ukubhoboza
I-billet evuthayo ibhobozwa yi-perforator ukuze yakhe ishubhu elimaholoholo elingenalutho. Indlela yokubhoboza evame ukusetshenziswa "i-oblique rolling perforation", esebenzisa ama-roller amabili azungezayo ukusunduza i-billet phambili ngenkathi uyizungezisa, ukuze isikhungo singenalutho.

4. Ukuginqika (ukuzelula)
Ipayipi elimahhadlahhadla elinezimbobo liyanwetshwa futhi lilinganiselwe ngezinto ezihlukahlukene zokugingqa. Ngokuvamile kunezindlela ezimbili:

Indlela yokuginqika eqhubekayo: Sebenzisa isigayo esinamapasi amaningi ukuze uginqike ngokuqhubekayo ukuze unwebe kancane kancane ipayipi elimahhadlahhadla futhi unciphise ukujiya kodonga.

Indlela ye-Pipe jacking: Sebenzisa i-mandrel ukusiza ekweluleni nasekugingqeni ukuze ulawule ububanzi bangaphakathi nangaphandle bepayipi lensimbi.

5. Ukulinganisa nokunciphisa
Ukuze kuzuzwe usayizi onembile odingekayo, ipayipi elimaholoholo licutshungulwa emshinini wokulinganisa noma umshini wokunciphisa. Ngokugoqa okuqhubekayo nokwelula, ububanzi bangaphandle nobukhulu bodonga lwepayipi kulungiswa.

6. Ukwelashwa kokushisa
Ukuze kuthuthukiswe izakhiwo zemishini yepayipi yensimbi futhi kuqedwe ukucindezeleka kwangaphakathi, inqubo yokukhiqiza ngokuvamile ihlanganisa inqubo yokwelapha ukushisa okufana nokujwayelekile, ukushisa, ukucisha noma ukukhishwa kwe-annealing. Lesi sinyathelo singathuthukisa ukuqina nokuqina kwepayipi lensimbi.

7. Ukuqondisa nokusika
Ipayipi yensimbi ngemva kokwelashwa kokushisa ingase igobe futhi idinga ukuqondisa ngokuqondisa. Ngemuva kokuqondisa, ipayipi yensimbi inqunywa ubude obufunwa yikhasimende.

8. Ukuhlola
Amapayipi ensimbi angenamthungo adinga ukuhlolwa kwekhwalithi okuqinile, okuvamise ukufaka lokhu okulandelayo:

Ukuhlolwa kokubukeka: Hlola ukuthi kukhona yini ukuqhekeka, amaphutha, njll. ebusweni bepayipi lensimbi.
Ukuhlolwa kobukhulu: Linganisa ukuthi ububanzi, ukujiya kodonga nobude bepayipi lensimbi kuyahlangabezana yini nezidingo.
Ukuhlolwa kwempahla ebonakalayo: njengokuhlolwa kwe-tensile, ukuhlolwa komthelela, ukuhlolwa kokuqina, njll.
Ukuhlola okungalimazi: Sebenzisa i-ultrasound noma i-X-ray ukuze uthole ukuthi kukhona yini imifantu noma izimbotshana ngaphakathi.
9. Ukupakisha nokulethwa
Ngemva kokudlulisa ukuhlolwa, ipayipi lensimbi liphathwa nge-anti-corrosion kanye ne-anti-rust treatment njengoba kudingekile, futhi lipakishwe futhi lithunyelwe.

Ngalezi zinyathelo ezingenhla, amapayipi ensimbi angenamthungo akhiqizwayo asetshenziswa kakhulu kuwoyela, igesi yemvelo, amakhemikhali, ubhayela, imoto, i-aerospace kanye neminye imikhakha, futhi aqashelwa kabanzi ngenxa yamandla awo aphezulu, ukumelana nokugqwala kanye nezakhiwo ezinhle zemishini.
