Yintoni ekufuneka ithathelwe ingqalelo xa uThenga iMibhobho yentsimbi engenamthungo eDiameter encinci?

1. Ukukhethwa kwezinto eziphathekayo kunye nokuSebenza
Okokuqala, luchaze ngokucacileyo uhlobo lwemathiriyeli—ukuba ukhetheimibhobho yentsimbi engenamthungoezenziwe 20 #, 45 # carbon steel, okanye ingxubevange yentsimbi. Izixhobo ezahlukeneyo zibonisa iipropathi zoomatshini ezahlukeneyo, ukuxhathisa ukubola, kunye neendawo ezifanelekileyo. Ngokomzekelo, i-20 # insimbi inika ukusebenza kakuhle ngokubanzi, i-45 # insimbi inika amandla aphezulu, ngelixa i-alloy steel ifanelekile kwiimeko ezizodwa zokusebenza. Kwangaxeshanye, qonda ukwakheka kweekhemikhali zemathiriyeli kunye nepropathi eqinisekisiweyo yoomatshini ukuqinisekisa ukuthotyelwa kweemfuno zokusetyenziswa.

2. Ukuthotyelwa kweMigangatho kunye neSiqinisekiso
Buza malunga nemigangatho yesizwe okanye yoshishino esetyenziswa kwiumbhobho wentsimbi ongenamthungo, njenge-GB/T8163 okanye i-GB/T3639. Ukongeza, qinisekisa ukuba umthengisi unazo iziqinisekiso ezifanelekileyo zenkqubo yomgangatho kunye neelayisensi zokwenziwa kwezixhobo ezizodwa. Ezi ziqinisekiso ziqinisekiso ezibalulekileyo zomgangatho wemveliso.

3. Ukuchaneka koMda kunye noLuhlu loNyamezelo
Ukuchaneka kobukhulu bubalulekile kububanzi obuncinciimibhobho engenamthungo. Cacisa ngokucacileyo uluhlu lonyamezelo kwidayamitha yangaphandle kunye nobukhulu bodonga, kunye neemfuno zokuthi tye. Imibhobho engenamthungo yodidi oluchanekileyo idla ngokufuna ukuchaneka okuphezulu komlinganiselo, njengokunyamezela idiamitha yangaphandle eyi-±0.05mm kunye nokuthe tye ≤0.5mm/m.

4. Inkqubo yeMveliso kunye noLawulo loMgangatho
Qinisekisa ukuba imibhobho yentsimbi engenamthungo iveliswa ngokuqengqeleka okushushu okanye umzobo obandayo, kunye neenkqubo ezithile zonyango lobushushu. Buza malunga nenkqubo yokulawula umgangatho womthengisi, kubandakanywa izixhobo zokuhlola kunye neeprothokholi zokuvavanya-ezifana nokuba iindlela zokuvavanya ezingonakaliyo ezifana nokufumanisa i-ultrasonic flaw okanye uvavanyo lwangoku lwe-eddy luyasetyenziswa.

5. UMgangatho woMphezulu kunye neeMfuno zoNyango
Misela iimfuno zonyango lwangaphezulu ngokusekelwe kwimeko yesicelo, njengokuba i-polish okanye i-sandblasting iyafuneka. Kwakhona cacisa iinkcukacha zokurhabaxa komphezulu, ezibaluleke kakhulu kusetyenziso oluchanekileyo olufana neenkqubo zamanzi.

6. Ukubonelela ngesakhono kunye nexesha lokuNika iNkokheli
Qinisekisa umthamo wemveliso yomthengisi kunye neshedyuli yonikezelo, ngakumbi kwiiprojekthi ezingxamisekileyo. Buza malunga namanqanaba oluhlu lweemveliso ezisemgangathweni kunye namaxesha okukhokelela kwimveliso kwizinto eziqhelekileyo ukuqinisekisa ukulungelelaniswa kunye nexesha leprojekthi.

7. Ubuncinane boMyinge woMyalelo kunye neMigaqo yokuRhweba
Qonda ubuncinci beemfuno zobungakanani bomyalelo, ngakumbi kwiintengo zeebhetshi ezincinci. Cacisa imigaqo yamaxabiso, kuquka ukubandakanywa kwerhafu kunye noxanduva lomthwalo, ukuphepha iindleko ezingalindelekanga.

8. Iindlela zokuPakisha kunye nokuThumela
Buza malunga neendlela zokupakisha (umzekelo, ukupakishwa okungangenwa ngumhlwa) ukuqinisekisa imfezeko yemveliso ngexesha lokuhamba nokugcinwa. Ukumisela eyona ndlela yokuhambisa ngenqanawa yokulinganisa iindleko kunye nexesha elifanelekileyo.

9. Ukuqinisekiswa koMgangatho kunye neNkonzo emva koThengiso
Cacisa imigaqo-nkqubo yoqinisekiso lomgangatho womthengisi, efana nokuba ngaba isiqinisekiso somgangatho sinikiwe na kunye nendlela imiba yomgangatho esingathwa ngayo. Qonda inkqubo yenkonzo emva kokuthengisa, kubandakanywa inkxaso yobugcisa kunye nesisombululo sezikhalazo ezisemgangathweni.

10. UBonelelo lweSampuli kunye neNqobo yoKwamkelwa
Kwiiprojekthi zokuthengwa kwezinto ezibalulekileyo, cela iisampuli zokuqinisekiswa kwangaphambili. Kwangaxeshanye, chaza imigangatho yokwamkelwa kunye neendlela zokuqinisekisa ukuba iimveliso ezizisiweyo zihlangabezana neemfuno ezilindelekileyo.
