Ukugcinwa kwepayipi elishiselwe abandayo kudinga ukunakekelwa njalo ngokuvumelana nezindinganiso zokulungisa ezihambisanayo. Ngisho noma isimo sokusebenza sisihle, kuyadingeka ukwenza ukunakekelwa nxazonke kuyunithi yepayipi elishiselwe ukuze ugweme ukwehluleka kwemishini futhi uqinisekise ukukhiqizwa okushelelayo.

Enqubweni yokugcina amapayipi ashiselwe abandayo, izingxenye ezitholakala ukuthi zigqoke kakhulu kufanele zishintshwe ngokushesha ngangokunokwenzeka. Ukugcinwa okuvamile nokuvikelwa kwemishini ngabasebenzi bokuvikela abangochwepheshe, njengokwengeza uwoyela wokugcoba, njll. Bese ugcoba uwoyela wokuqeda ukugqwala wekhwalithi ephezulu ohlangothini olushelelayo ukuze uvimbele okokusebenza ukuthi ku-oxidizing nokugqwala, ikakhulukazi uma kungenzi lutho isikhathi eside. . Ukwenza umsebenzi omuhle ekugcinweni kwemininingwane kuhle kakhulu emsebenzini ojwayelekile wamapayipi ashiselwe abandayo, futhi kungaqinisekisa ukuqhubeka kahle kokukhiqiza.

Emsebenzini wokulungisa wansuku zonke, iphuzu elibalulekile ukuqaphela, kungakhathaliseki ukuthi imayelana nomsebenzi wonke wepayipi elishiselwe abandayo, noma mayelana nokushintshwa kwezingxenye ezihlukahlukene, hlola njalo ukuguga kwezingxenye, ikakhulukazi uma umsebenzi iyasinda, naka kakhulu lezi Zingxenye, uma kwenzeka ukuguga kuthinta kakhulu inqubo yokukhiqiza.

1. Mayelana nezinzuzo zezomnotho, umsindo wamapayipi ashiselwe abandayo mncane; ukusetshenziswa kwesistimu yokupholisa amanzi ajikelezayo kuhambisana nemvelo futhi konga amandla.
2. Mayelana nokusetshenziswa, amapayipi ashiselwe asetshenziswa kabanzi futhi afaneleka ukukhiqizwa kwezolimo nezimboni.
3. Ngokwekhwalithi, imikhiqizo yamapayipi ashiselwe amapayipi ashiselwe abandayo mihle, ama-welds aqinile, awekho ama-burrs amaningi, isivinini siyashesha, ukonga amandla kanye nokonga izindleko.
4. Ngenxa yokuthi ipayipi eline-weld high-frequency inezinzuzo zekhwalithi ye-weld enhle, ama-burrs amancane angaphakathi nangaphandle, isivinini esiphezulu sokushisela, nokusetshenziswa kwamandla aphansi, iye yasetshenziswa kabanzi futhi yakhuthazwa.
5. Kuyunithi yamapayipi ashiselwe, ngokuvamile kungenzeka ukukhiqiza amapayipi ahlukene nobulili obuhlukile, futhi amapayipi amaningi angama-square kanye nama-rectangular akhiqizwa. Ngenxa yokuthi amapayipi angama-square kanye nama-rectangular ane-modulus yesigaba esikhulu, amapayipi ashiselwe abandayo angakwazi ukumelana namandla amakhulu okugoba, angasindisa insimbi eningi, Inezinzuzo zokulondoloza isikhathi sokucubungula nokunciphisa isisindo sezingxenye, ngakho-ke kuya ngokuya kuthandwa. futhi isetshenziswa emikhakheni eyahlukene yezimboni nezolimo.

Kunezinqubo eziningi ohlelweni lokucutshungulwa kwamapayipi ashiselwe, futhi yonke imininingwane idinga ukunakwa kwethu. Amapayipi ashiselwe kudingeka enze izinqubo ezihlukahlukene ngaphambi kokusetshenziswa. Ukwelashwa kokushisa kwepayipi lensimbi elihlanganisiwe kuyisixhumanisi esibalulekile enqubweni yepayipi yensimbi ehlanganisiwe. Ukucubungula okushisayo kuyinqubo yensimbi yokucubungula ukushisa okushisayo, ukushisa, ukushisa, nokupholisa izinto zensimbi endaweni ethile, futhi ilawula izakhiwo zensimbi ngokushintsha isakhiwo se-metallographic songaphezulu noma ingaphakathi lento.

Phakathi nenqubo yokushisisa nokupholisa yesakhiwo sokusebenza sepayipi elishiselwe, ngenxa yesivinini sokupholisa esingaguquki nesikhathi songqimba olungaphezulu kanye nesendlalelo esiwumgogodla, kuzokwakhiwa umehluko wokushisa, okuholela ekwandeni kwevolumu engalingani kanye nokufinyela, kanye nokucindezeleka, okungukuthi. , ukucindezeleka okushisayo. Ngaphansi kwesenzo sokucindezeleka okushisayo, izinga lokushisa lokuqala le-surface layer liphansi kunesendlalelo esiyinhloko, futhi ukuncipha kukhulu kunesendlalelo esiyinhloko, ukuze ungqimba oluyisisekelo lunwetshwe. Lapho ukupholisa sekuphelile, isikhumba sicindezelwe futhi umnyombo weluliwe, ngoba ukuncishiswa kwevolumu yokupholisa komgogodla akukwazi ukuqhubeka ngokukhululekile.
