Ipayipi Elishisayo Elinwetshiwe Elingenamthungo Elingenasici Lepayipi Lensimbi Engenasici
Incazelo
Ipayipi lensimbi elinwebekayo elishisayo amapayipi anwetshiwe angenamthungo ashisayo, anomthamo omncane kakhulu kodwa ukufinyela kwepayipi lensimbi eliqinile (ipayipi elingenamthungo) kungabizwa ngokuthi ukunwetshwa okushisayo.Inqubo ye-skew rolling noma indlela yokudweba yokwandisa ububanzi bepayipi.Steel ipayipi ukujiya ngesikhathi esifushane, angaveza non-standard futhi izinhlobo ezikhethekile amashubhu nekhono nge izindleko eziphansi futhi okusezingeni eliphezulu ukukhiqiza ukusebenza kahle, intuthuko yamanje ngamazwe emkhakheni tube rolling.
Ipayipi elishisayo lokwandisa ngokwandisa ububanzi bepayipi ukuqeda izinqubo - inqubo yokwandisa okushisayo yokukhiqizwa kwepayipi lensimbi.Ipayipi lokunweba elishisayo livame ukubizwa ngamapayipi ensimbi anwetshiwe angenamthungo.

I-Painting & Coating
Ukwelashwa okungaphezulu kwepayipi lensimbi:
Ukuze kuthuthukiswe impilo yesevisi yepayipi likawoyela, ukwelashwa okungaphezulu kuvame ukwenziwa ukuze kube lula ukuhlanganiswa okuqinile kwepayipi lensimbi kanye ne-anticorrosive coating.Izindlela zokucubungula ezivamile yilezi: ukuhlanza, ukuchithwa kwamathuluzi, ukuchotshozwa, ukuqhuma kokudubula okuqeda izigaba ezine.
I-1 yokuhlanza Amafutha, uthuli, i-lubricant, i-organic matter enamathela phezu kwepayipi lensimbi, ngokuvamile isebenzisa i-solvent, i-emulsion ukuhlanza indawo. izindlela zokwelapha ziyadingeka.Ukususwa kokugqwala kwethuluziIpayipi lensimbi elingaphezulu kwe-oxide, ukugqwala, i-welding slag, lingasebenzisa ibhulashi lensimbi yensimbi ukuhlanza nokupholisha indawo yokwelapha.Ukukhipha ithuluzi kungahlukaniswa kube imanuwali namandla, ukuchithwa kwamathuluzi okwenziwa ngesandla kungafinyelela ku-Sa
Izinga le-2, ukuchithwa kwethuluzi lamandla kungafinyelela izinga le-Sa3. Uma ubuso bepayipi lensimbi buhlanganiswe nesikhumba esiqinile se-oxide, kungase kungenzeki ukususa ukugqwala ngosizo lwamathuluzi, ngakho-ke sidinga ukuthola ezinye izindlela.
3 pickling Izindlela ezivamile zokukhetha zihlanganisa ikhemistri kanye ne-electrolysis.Kodwa ukucotshwa kwamakhemikhali kuphela okusetshenziselwa ukuvikela ukugqwala kwepayipi.Ukucosha ngamakhemikhali kungafinyelela izinga elithile lokuhlanzeka kanye nokubamadlakela ebusweni bepayipi lensimbi, elilungele imigqa yehange elandelayo.Ngokuvamile njenge-a ukudubula (isihlabathi) ngemva kokucubungula kabusha.
4 shot ukuqhuma ukuze kukhishwe ukugqwalaNgenjini enamandla amakhulu ukushayela ama-blades azungezayo anesivinini esikhulu, igrit yensimbi, isibhamu sensimbi, ingxenye, amaminerali nolunye izintambo ezilumayo ngaphansi kokusebenza kwamandla aphakathi nendawo kusifutho sepayipi lensimbi kanye nokukhishwa okukhulu, susa ukugqwala, ama-oxide. kanye nokungcola ngakolunye uhlangothi, ngakolunye uhlangothi, ipayipi lensimbi ngaphansi kwesenzo somthelela wodlame olubi namandla okungqubuzana, ukuze kuzuzwe ubulukhuni obufanayo obudingekayo.Phakathi kwezindlela ezine zokwelapha, ukudubula ukuqhuma nokususa kuyindlela ekahle yokwelapha yokususa ipayipi.Ngokuvamile, ukuqhunyiswa kwesibhamu nokususa insimbi kusetshenziselwa ikakhulukazi ukwelashwa kwendawo yangaphakathi yepayipi lensimbi, futhi ukuqhuma nokususa isibhamu kusetshenziswa kakhulu ukwelapha ngaphandle kwepayipi lensimbi.

FAQ
1. Ithini imigomo yakho yokukhokha?
A: (1)T/T: 30% idiphozi kusengaphambili, ibhalansi 70% ikhokhwe ngaphambi kokuthunyelwa
(2)30% inkokhelo ephansi, ibhalansi engu-70% ikhokhwe ngokuqhathaniswa ne-L/C lapho ibonakala.
2. Yisiphi isikhathi sakho sokulethwa?
A: Izinsuku zokusebenza eziyi-15-20 ngemuva kokuthola idiphozithi noma i-L/C yasekuqaleni.
3. Inkampani yakho inesikhathi esingakanani isebhizinisini?
A: Singabakhiqizi bezinto zokwakha iminyaka engu-20 embonini yensimbi.
4. Singavakashela imboni yakho ukuze sihlole inqubo yokukhiqiza kanye nekhwalithi?
A: Yebo, kunjalo, wamukelekile nganoma yisiphi isikhathi.
5: Ingabe unaso isitifiketi sokugaya kanye nombiko wokuhlaziya ingxenye ebalulekile?
A: Yebo sinomnyango wokuhlaziya ikhwalithi oqeqeshiwe.
Sinikezela ngombiko wekhwalithi weqoqo ngalinye lezimpahla.
