Uma uhlangabezana ne-oda elidinga ukukhiqizwa, ngokuvamile kuyadingeka ukulinda ishejuli yokukhiqiza, ehluka kusukela ezinsukwini ezingu-3-5 kuya ezinsukwini ezingu-30-45, futhi usuku lokulethwa kumele luqinisekiswe nekhasimende ukuze izinhlangothi zombili zifinyelele esivumelwaneni.

Inqubo yokukhiqiza amapayipi ensimbi angenamthungo ihlanganisa ikakhulukazi izinyathelo ezilandelayo ezibalulekile:

1. Ukulungiselela i-billet
Izinto zokusetshenziswa zamapayipi ensimbi angenamthungo yinsimbi eyindilinga noma ama-ingot, ngokuvamile insimbi yekhabhoni esezingeni eliphezulu noma insimbi engenangxube eningi. I-billet iyahlanzwa, ubuso bayo buyahlolwa ukuthi abunazo yini iziphambeko, bese inqunywa ngobude obudingekayo.

2. Ukushisa
I-billet ithunyelwa esithandweni sokushisa ukuze ifudumale, ngokuvamile ekushiseni okushisayo okungaba ngu-1200℃. Ukushisa okufanayo kumele kuqinisekiswe ngesikhathi senqubo yokushisa ukuze inqubo elandelayo yokubhoboza iqhubeke kahle.

3. Ukubhoboka
I-billet efudumele imbozwa yi-perforator ukuze kwakheke ipayipi eliyi-hollow rough. Indlela evame ukusetshenziswa yokumbozwa yi-"oblique rolling perforation", esebenzisa ama-roller amabili ajikelezayo a-oblique ukuze asunduze i-billet phambili ngenkathi eyijikelezisa, ukuze isikhungo sibe yi-hollow.

4. Ukugingqa (ukuzelula)
Ipayipi elinombobo elinombobo liyanwetshwa futhi lilinganiswe ngemishini ehlukahlukene yokugoqa. Ngokuvamile kunezindlela ezimbili:

Indlela yokugoqa eqhubekayo: Sebenzisa umshini wokugoqa odlula ngezindlela eziningi ukuze ugoqe ngokuqhubekayo ukuze wandise kancane kancane ipayipi eliqinile futhi unciphise ukujiya kodonga.

Indlela yokujaha amapayipi: Sebenzisa i-mandrel ukusiza ekweluleni nasekugingqini ukuze ulawule ububanzi bangaphakathi nobangaphandle bepayipi lensimbi.

5. Usayizi nokunciphisa
Ukuze kufezwe usayizi oqondile odingekayo, ipayipi elingaqinile licutshungulwa kumshini wokugaya usayizi noma umshini wokugaya onciphisayo. Ngokugoqa nokunwebeka okuqhubekayo, ububanzi bangaphandle kanye nobukhulu bodonga lwepayipi kuyalungiswa.

6. Ukwelashwa ngokushisa
Ukuze kuthuthukiswe izakhiwo zemishini zepayipi lensimbi futhi kuqedwe ukucindezeleka kwangaphakathi, inqubo yokukhiqiza ivame ukufaka inqubo yokwelapha ukushisa njengokulungisa, ukuqinisa, ukucima noma ukuqinisa. Lesi sinyathelo singathuthukisa ukuqina nokuqina kwepayipi lensimbi.

7. Ukuqondisa nokusika
Ipayipi lensimbi ngemva kokwelashwa kokushisa lingase ligotshwe futhi lidinga ukuqondiswa nge-straightener. Ngemva kokuqondisa, ipayipi lensimbi lisikwa libe ubude obudingwa yikhasimende.

8. Ukuhlolwa
Amapayipi ensimbi angenamthungo adinga ukuhlolwa kwekhwalithi okuqinile, okuvame ukufaka okulandelayo:

Ukuhlolwa kokubukeka: Hlola ukuthi kukhona yini imifantu, amaphutha, njll. ebusweni bepayipi lensimbi.
Ukuhlolwa kobukhulu: Kala ukuthi ububanzi, ukujiya kodonga kanye nobude bepayipi lensimbi kuyahlangabezana yini nezidingo.
Ukuhlolwa kwempahla ebonakalayo: njengokuhlolwa kokudonseka, ukuhlolwa komthelela, ukuhlolwa kobulukhuni, njll.
Ukuhlolwa okungabhubhisi: Sebenzisa i-ultrasound noma i-X-ray ukuthola ukuthi kukhona yini imifantu noma ama-pores ngaphakathi.
9. Ukupakisha nokulethwa
Ngemva kokudlula ukuhlolwa, ipayipi lensimbi liphathwa ngokwelashwa kokulwa nokugqwala kanye nokulwa nokugqwala njengoba kudingeka, bese lipakishwa bese lithunyelwa.

Ngezinyathelo ezingenhla, amapayipi ensimbi angenamthungo akhiqizwayo asetshenziswa kabanzi ku-oyili, igesi yemvelo, amakhemikhali, amabhoyila, izimoto, izindiza kanye neminye imikhakha, futhi aqashelwa kabanzi ngamandla awo aphezulu, ukumelana nokugqwala kanye nezakhiwo ezinhle zemishini.
