Xa udibana nomyalelo ekufuneka uveliswe, ngokuqhelekileyo kuyimfuneko ukulinda ukucwangciswa kwemveliso, eyahluka ukusuka kwiintsuku ezi-3-5 ukuya kwiintsuku ezingama-30-45, kwaye umhla wokuhanjiswa kufuneka uqinisekiswe kunye nomthengi ukuze omabini amaqela afikelele isivumelwano.

Inkqubo yokuvelisa imibhobho yentsimbi engenamthungo ikakhulu ibandakanya la manyathelo abalulekileyo alandelayo:

1. Ukulungiswa kwebhilethi
Izinto eziluhlaza zemibhobho yensimbi engenamthungo ziyintsimbi ejikelezayo okanye i-ingots, ngokuqhelekileyo i-carbon steel high quality okanye i-low-alloy steel. I-billet ihlanjululwe, indawo yayo ihlolwe iziphene, kwaye inqunywe ubude obufunekayo.

2. Ukufudumeza
I-billet ithunyelwa kwiziko lokufudumeza ukufudumeza, ngokuqhelekileyo kwiqondo lokushisa elimalunga ne-1200 ℃. Ukufudumala okufanayo kufuneka kuqinisekiswe ngexesha lokufudumeza ukwenzela ukuba inkqubo yokubhoboza elandelayo iqhube kakuhle.

3. Ukugqobhoza
Ibillet eshushu igqojozwa ngumbhobho ukwenza umbhobho orhabaxa. Indlela esetyenziswa ngokuqhelekileyo yokugqobhoza "i-oblique rolling perforation", esebenzisa iirola ezijikelezayo ezimbini ezijikelezayo ukutyhala i-billet phambili ngelixa ijikeleziswa, ukuze iziko libe ligobile.

4. Ukuqengqeleka (ukusolula)
Umbhobho orhabaxa onemingxuma woluliwe kwaye ulinganiswe ngezixhobo ezahlukeneyo zokuqengqeleka. Ngokuqhelekileyo kukho iindlela ezimbini:

Indlela yokuqengqeleka eqhubekayo: Sebenzisa ilitye lokusila elineepasi ezininzi ukuqengqeleka ngokuqhubekayo ukwandisa ngokuthe ngcembe umbhobho orhabaxa nokunciphisa ubukhulu bodonga.

Umbhobho jacking indlela: Sebenzisa mandrel ukuncedisa ukolula kunye rolling ukulawula idayamitha yangaphakathi nangaphandle umbhobho yentsimbi.

5. Ubungakanani kunye nokunciphisa
Ukuze kuphunyezwe ubungakanani obuchanekileyo obufunekayo, umbhobho orhabaxa ucutshungulwa kwilitye lokulinganisa okanye umlinganiselo wokunciphisa. Ngokuhamba ngokuqhubekayo kunye nokwelula, ububanzi bangaphandle kunye nobukhulu bodonga lombhobho kulungiswa.

6. Unyango lobushushu
Ukuze kuphuculwe iimpawu zomatshini wombhobho wensimbi kunye nokuphelisa uxinzelelo lwangaphakathi, inkqubo yokuvelisa ngokuqhelekileyo ibandakanya inkqubo yonyango lokushisa njengesiqhelo, ukufudumala, ukucima okanye ukucima. Eli nyathelo linokuphucula ukuqina kunye nokuqina kombhobho wensimbi.

7. Ukulungelelanisa kunye nokusika
Umbhobho wensimbi emva kokunyangwa kobushushu unokugoba kwaye kufuneka uqondiswe ngumlungiseleli. Emva kokulungiswa, umbhobho wensimbi unqunywe ubude obufunwa ngumthengi.

8. Ukuhlolwa
Imibhobho yentsimbi engenamthungo kufuneka ihlole umgangatho ongqongqo, odla ngokuquka oku kulandelayo:

Ukuhlolwa kokubonakala: Khangela ukuba kukho iintanda, iziphene, njl njl kumphezulu wepayipi yensimbi.
Ukuhlolwa komlinganiselo: Linganisa ukuba ububanzi, ubukhulu bodonga kunye nobude bombhobho wentsimbi buhlangabezana neemfuno.
Ukuhlolwa kwepropathi ebonakalayo: njengovavanyo lwe-tensile, uvavanyo lwempembelelo, uvavanyo lobunzima, njl.
Uvavanyo olungonakalisi: Sebenzisa i-ultrasound okanye i-X-ray ukujonga ukuba kukho iintanda okanye iipores ngaphakathi.
9. Ukupakishwa kunye nokuhanjiswa
Emva kokugqithisa ukuhlolwa, umbhobho wensimbi uphathwa nge-anti-corrosion kunye ne-anti-rust unyango njengoko kufuneka, kwaye upakishwe kwaye uthunyelwe.

Ngala manyathelo angasentla, imibhobho yentsimbi engenamthungo eveliswayo isetyenziswa kakhulu kwioyile, kwirhasi yendalo, kwikhemikhali, kwibhoyila, kwimoto, kwi-aerospace kunye neminye imimandla, kwaye yamkelwa ngokubanzi ngenxa yamandla ayo aphezulu, ukuxhathisa ukubola kunye neempawu ezilungileyo zoomatshini.
