Mumapaipi etsvina esimbi isina ngura mune mafuta mushure mekunge apera, uye anofanira kugadziriswa nekuomeswa asati aitwa mamwe mabasa anotevera.
1. Chimwe ndechekudurura mudziyo wekudziisa mafuta zvakananga mudziva, wobva wawedzera mvura wonyika. Mushure memaawa gumi nemaviri, unogona kuuchenesa zvakananga.
2. Imwe nzira yekuchenesa ndeyekuisa pombi yesimbi isingatsvi mumafuta edhiziri, kuinyika kwemaawa matanhatu, wozoiisa mudziva rine mushonga wekuchenesa, kuinyika kwemaawa matanhatu, wozoichenesa.
Maitiro echipiri ane zvakanakira zviri pachena. Zvakachena kuchenesa mapaipi esimbi isina ngura.
Kana kubviswa kwemafuta kusina kuchena zvakanyanya, kuchava nemigumisiro yakajeka pakugadzirisa kunotevera uye nzira yekubvisa mafuta mu vacuum. Kana kubviswa kwemafuta kusina kuchena, chekutanga, kupukuta kuchave kwakaoma kuchenesa uye kupukuta hakuzove kwakajeka.
Chechipiri, kana kupenya kwapera, chigadzirwa chinobviswa zviri nyore, izvo zvisingavimbise chigadzirwa chemhando yepamusoro.
Kururama kwepombi yesimbi isina ngura kunoda kururamiswa
Chitarisiko chakajeka, buri remukati rakatsetseka:
Pombi yesimbi isina tsvina inopedzwa kupedzwa mukati nekunze kwenzvimbo ine hukasha hwepamusoro hweRa≤0.8μm
Kuomarara kwenzvimbo dzemukati nedzekunze dzechubhu yakakweshwa kunogona kusvika paRa≤0.4μm (senge girazi)
Kazhinji, michina mikuru yekupukuta mapaipi esimbi isina tsvina ndiyo musoro wekupukuta, nekuti kuomarara kwemusoro wekupukuta ndiko kunosarudza kurongeka kwekupukuta kwakashata.
BA:Kupenya Kwakajeka. Munguva yekudhirowa kwepombi yesimbi, zvechokwadi inoda mafuta ekuzora, uye tsanga dzichakanganiswawo nekuda kwekugadziriswa. Kuti mafuta aya asarambe ari mupombi yesimbi, pamusoro pekuchenesa pombi yesimbi, unogona zvakare kushandisa argon gasi semhepo iri muchoto panguva yekubatidza kupisa kwakanyanya kubvisa deformation, uye kuchenesa pombi yesimbi nekubatanidza argon nekabhoni neokisijeni pamusoro pepombi yesimbi kuti itsve. Pamusoro payo panoita kuti pave nemhedzisiro yakajeka, saka nzira iyi yekushandisa pure argon annealing kupisa nekutonhodza nzvimbo inopenya inonzi glow annealing. Kunyangwe kushandisa nzira iyi kupenya pamusoro kunogona kuve nechokwadi chekuti pombi yesimbi yakachena zvizere, isina kusvibiswa kwekunze. Zvisinei, kupenya kwenzvimbo iyi kuchanzwa senge nzvimbo isina matte kana zvichienzaniswa nedzimwe nzira dzekupolisha (mechanical, chemical, electrolytic). Ehe, mhedzisiro yacho ine chekuitawo nezviri muargon uye huwandu hwenguva dzekudziya.
EP:kupolisha kwemagetsi (Electro Polishing), electrolytic polishing inyaya yekushandisa anode treatment, uchishandisa musimboti we electrochemistry kugadzirisa zvakakodzera voltage, current, acid composition, uye polishing time, kwete kungoita kuti pamusoro pave nechiedza uye kutsetseka chete, kuchenesa kunogonawo kuvandudza corrosion resistance ye corrosion ye pamusoro, saka ndiyo nzira yakanakisisa yekujekesa pamusoro. Ehe, mutengo wayo uye tekinoroji zvinowedzerawo. Zvisinei, nekuti electrolytic polishing icharatidza mamiriro ekutanga e steel pipe surface, kana paine mavanga akakomba, maburi, slag inclusions, precipitates, nezvimwewo pamusoro pe steel pipe surface, zvinogona kukonzera electrolysis failure. Musiyano kubva ku chemical polishing ndewekuti kunyangwe ichiitwawo munzvimbo ine acidic, hakuzovi ne grain boundary corrosion pamusoro pe steel pipe chete, asi ukobvu hwe chromium oxide film pamusoro payo hunogonawo kudzorwa kuti uwane corrosion resistance yakanakisa ye steel pipe.
