1. Ngaphambi kokususwa kokugqwalaamapayipi ensimbi adonswa abandayo, ukungcola okuhlukahlukene okubonakalayo ebusweni kufanele kukhishwe kuqala, bese kusetshenziselwa i-solvent noma i-ejenti yokuhlanza ukuze kukhishwe amafutha.
2. Sebenzisa ifosholo lensimbi ye-tungsten ukuze ususe izindawo ezinkulu zokugqwala.
3. Sebenzisa i-scraper kanye nebhulashi locingo ukuze ususe ukugqwala emaphethelweni nasemakhoneni epayipi lensimbi.
4. Sebenzisa ifayela ukuze ususe ama-protrusions afana ne-welding slag kanye nama-burrs ahlukahlukene avela kumapayipi ensimbi.
5. Amapayipi ensimbi adonsa abandayo kufanele ahlanzwe ngendwangu yesanti kanye nebhulashi lensimbi yensimbi.
(1) Ukungcoliswa kwepayipi lensimbi ikhabhoni yensimbi: imihuzuko ebangelwa ukuthintana nezingxenye zensimbi ye-carbon yakha Ibhethri eliyinhloko elinendawo yokugqwala, okuholela ekugqwaleni kwe-electrochemical.
(2) Ukusika ipayipi lensimbi elidonsa ngokubanda: ukunamathiselwa kwezinto ezivame ukugqwala ezifana ne-slag yokusika kanye ne-spatter kanye nokwakheka kwebhethri eliyisisekelo elinamandla okugqwala kuzodala ukugqwala kwe-electrochemical.
(3) Ukulungisa ukubhaka: ukwakheka kanye nesakhiwo se-metallographic sendawo yokushisisa ilangabi kushintsha ngokungalingani, kwakheka ibhethri Eliyisisekelo elinendawo yokugqwala, okuholela ekugqwaleni kwe-electrochemical.
(4) Ukushisela amapayipi ensimbi: ukukhubazeka ngokomzimba (i-undercut, pore, crack, fusion engaphelele, ukungena okungaphelele, njll.) kanye nokukhubazeka kwamakhemikhali (okusanhlamvu okumahhadla, i-chromium empofu emngceleni wokusanhlamvu, ukuhlukaniswa, njll.) endaweni yokushisela ifomu Primary ibhethri eline-corrosion medium ukukhiqiza ukugqwala kwe-electrochemical.
(5) Impahla: ukukhubazeka kwamakhemikhali (ukwakheka okungalingani, ukungcola kwe-S, P, njll.) kanye nokukhubazeka okungaphezulu (ukuxega, izimbobo zesihlabathi, ukuqhekeka, njll.) kwepayipi lensimbi kulungele ukwakhiwa kwebhethri Eliyisisekelo elinendawo yokugqwala futhi elikhiqizayo. ukugqwala kwe-electrochemical.
(6) I-Passivation: I-acid pickling engeyinhle ibangela ukugqwala kwefilimu engalingani noma ezacile ebusweni bamapayipi ensimbi adonsa abandayo, ajwayele ukugqwala nge-electrochemical.
Kafushane, lesi isifinyezo solwazi olufanele mayelana nokususwa kokungcola kanye nokwelashwa ngamakhemikhali kwamapayipi ensimbi adonswa ngokubanda.Ngikholwa ukuthi wonke umuntu unokuqhubeka nokufunda nokuqonda.Uma usafuna ukufunda ulwazi olwengeziwe, sicela uqhubeke nokusilandela.
