Nekukurumidza kukura kweindasitiri yesimba remumba, kushandiswa kwepombi dzesimbi dzisina tsvinairi kuwedzerawo nokukurumidza. Mukuita kwekuvaka anti-corrosion yemafuta uye gasi mapaipi, kune 304 Stainless steel capillaries, ayo ari akanyanya-chaiyo pombi. Iko kurapwa kwepamusoro kwepombi dzesimbi isina tsvina ndechimwe chezvinhu zvakakosha zvinotaridza hupenyu hwesevhisi yepipeline anti-corrosion, uye zvakare chinhu chakakosha chinodiwa pakubatanidzwa kwakasimba kweiyo anti-corrosion layer uye pombi yesimbi isina tsvina. Mukuwedzera kune rudzi rwekuputira, kupfekedza kwehutano uye nharaunda yekuvaka, hupenyu hwehutachiona hwehutachiona hunoenderana nehutano hwekugadzirisa kwepamusoro kwepombi yesimbi isina tsvina, iyo inotora inenge hafu yehupenyu. Naizvozvo, zvinodikanwa kuti unyatso kutevedzera zvinodiwa zveiyo anti-corrosion layer inotsanangurwa pamusoro pepombi dzesimbi dzisina tsvinauye ramba uchinatsiridza nzira yekurapa pamusoro pepombi dzesimbi isina tsvina.
Parizvino, nzira dzakajairika dzekurapa pamusoro pepombi dzesimbi dzisina tsvina dzinonyanya kuchenesa, kubvisa ngura, pickling, etc. Nzira idzi dzinotangwa pazasi.
Kuchenesa
Kushandisa zvinonyungudutsa uye emulsions kuchenesa pamusoro pesimbi isina tsvina kunogona kubvisa mafuta, girisi, guruva, mafuta uye zvakafanana organic zvinhu, asi nzira iyi haigoni kubvisa ngura, chiyero, welding flux, nezvimwewo pamusoro pesimbi isina tsvina, saka inongova imwe nzira yekubatsira mukugadzira anti-corrosion.
Tool ngura kubvisa
Kazhinji, maturusi akadai semabhurashi ewaya anoshandiswa kukwenenzvera pamusoro pesimbi isina tsvina, iyo inogona kubvisa yakasununguka kana kusimudza chiyero, ngura, welding slag, etc. Manual tool kubvisa ngura inogona kusvika kuSa2 level, uye simba rekushandisa ngura kubvisa kunogona kusvika kuSa3 level. . Kana pamusoro pesimbi isina tsvina yakanyatsonamirwa pachiyero chesimbi oxide, chishandiso chekubvisa ngura hachina kunaka uye haigone kusvika pakudzika kweanchor pateni inodiwa neanti-corrosion kuvaka.
Pickling
Kazhinji pane nzira mbiri dzekunhonga: makemikari uye electrolytic. Stainless simbi pombi inorwisa-corrosion inongoshandisa kemikari pickling, iyo inogona kubvisa chikero, ngura, uye chirairo chekare. Dzimwe nguva nzira iyi inogona kushandiswa zvakare sekurapazve mushure mekubvisa ngura yejecha. Kunyangwe kucheneswa kwemakemikari kuchigona kuita kuti nzvimbo isvike pahutsanana uye kushata, patani yeanchor yayo haina kudzika uye iri nyore kusvibisa nharaunda.
Shot blasting
Shot blasting inzira yekuputika kubvisa ngura. Motokari ine simba guru inotyaira blade inoputika kuti itenderere nekumhanya kukuru, kuitira kuti mabrasives akadai sejecha resimbi, simbi inopfura, zvikamu zvewaya, uye zvicherwa zvinoputika pamusoro pepombi yesimbi pasi pekuita kwesimba recentrifugal. Haikwanise chete kubvisa ngura, oxides uye tsvina, asi zvakare inowana inodiwa yunifomu roughness pasi pesimba rechisimba uye friction yeabrasive.
Mushure mekuputika kubvisa ngura, haingogone chete kuwedzera iyo yemuviri adsorption mhedzisiro pamusoro pepombi yesimbi isina tsvina, asi zvakare inosimudzira mechanical adhesion pakati pe-anti-corrosion layer uye pombi pamusoro. Naizvozvo, pfuti inoputika kubvisa ngura inzira yakanaka yekubvisa ngura yekudzivirira kusvibiswa kwepombi. Kazhinji, kupfurwa kunopisa ngura kunonyanya kushandiswa kugadzirisa mukati mepombi, uye pfuti inoputika kubvisa ngura inonyanya kushandiswa pakurapa kwekunze kwepombi. Nyaya dzinoverengeka dzinofanirwa kutariswa kana uchishandisa pfuti inoputika kubvisa ngura.
