Round Capillary Stainless Steel pombi
Hunhu 304 zvinhu Stainless simbi pombi
1. Pombi yesimbi isina tsvina yakagadzirwa ne304 inonyanya kushamwaridzana, yakachengeteka uye yakavimbika kushandisa.
2. Iyo 304 simbi isina tsvina pombi inogona kukotama nepamusoro Gini kushanda kusvika pamwero mukuru.Isu tinoziva kuti nharaunda yekuvaka kazhinji inokanganisa pombi yesimbi isina tsvina, asi vashandi vanozoita kuvaka zvinoenderana nekukanganisa kukuru kwepombi yesimbi isina tsvina.
3. Iyo 304 Stainless simbi pombi ine zvakanyanyisa kupikisa kune acid uye alkali corrosion.Kune firimu rakatetepa rinodzivirira riri kunze kwepombi yesimbi isina tsvina, asi yakaoma zvikuru.Kunyange kana pombi yesimbi isina tsvina yakakuvadzwa, chero bedzi pane okisijeni yakapoteredza Kana iripo, ipapo achavandudza nokukurumidza, uye hapazovi nemarara.
4. Unhu hwe 304 pombi yesimbi isina tsvina yakareruka, saka zviri nyore kutakura nekuiisa, iyo inoderedza zvakanyanya mari yeprojekti.
Mechanical properties uye maitiro epombi dzesimbi isina tsvina
Stainless simbi inoreva simbi inoshingirira pakuora zvisina simba semhepo, chiutsi, nemvura, uye zvinosvibisa makemikari zvakaita seasidhi, alkali, uye munyu, inozivikanwawo sesimbi isina asidi.Mukushandisa, simbi inoshingirira kune isina kusimba inoodza media inowanzonzi Stainless simbi, uye simbi inoshingirira kuchemical media corrosion inodaidzwa kuti acid-resistant simbi.Nekuda kwemusiyano wekuumbwa kwemakemikari pakati pezviviri izvi, yekutanga haigone kurwisa kemikari media corrosion, nepo iyo yekupedzisira kazhinji isina tsvina.Iyo corrosion resistance yesimbi isina tsvina inobva pane alloying zvinhu zviri musimbi.
Hunhu hunokosha hwesimbi isina tsvina:
1.Weldability
Kushandiswa kwakasiyana kwechigadzirwa kune zvakasiyana zvinodiwa pakuita welding.Kirasi yetafuraware kazhinji haidi kuita welding, uye inotosanganisira mamwe mabhizinesi ehari.Nekudaro, zvigadzirwa zvakawanda zvinoda kuita kwakanaka kwewelding yezvigadzirwa, seyechipiri-kirasi tableware, thermos makapu, pombi dzesimbi, hita dzemvura, madhishi emvura, nezvimwe.
2. Corrosion resistance
Zvizhinji zvezvigadzirwa zvesimbi zvisina tsvina zvinoda kumira zvakanaka, seKirasi I uye II tableware, midziyo yekubikira, maheater emvura, madhishi emvura, nezvimwewo. Vamwe vatengesi vekunze vanoitawo bvunzo dzekudzivirira ngura pane zvigadzirwa: shandisa NACL aqueous solution kuipisa kusvika pakuvira, woidira pashure penguva yakati.Bvisa mhinduro, geza uye uome, uye uyera kurema kuti uone dhigirii yekuora (Cherechedza: Kana chigadzirwa chakwenenzverwa, iyo Fe yemukati mumucheka weabrasive kana sandpaper inokonzera ngura pamusoro panguva yekuedzwa).
3. Kuchenesa kuita
Munzanga yanhasi, zvigadzirwa zvesimbi zvisina simbi zvinowanzokwenenzverwa panguva yekugadzirwa, uye zvishoma chete zvigadzirwa senge zvidziya zvemvura uye mvura inodhiza liner hazvidi kukwenenzverwa.Naizvozvo, izvi zvinoda kuti kukwenenzverwa kwechigadzirwa chacho kwakanaka kwazvo.Izvo zvinhu zvikuru zvinokanganisa kuita kwe polishing ndezvizvi:
① kuremara kwepamusoro kwemidziyo.Zvakadai sekukwenya, gomba, pickling, nezvimwe.
②Dambudziko rezvigadzirwa.Kana iyo kuomarara kwakadzikira, hazvizove nyore kukwenenzverwa kana uchikwenenzverwa (iyo BQ pfuma haina kunaka), uye kana kuomarara kwakadzikira, chiitiko che orange peel chiri nyore kuoneka pamusoro panguva yekudhirowa kwakadzika, zvichikanganisa. iyo BQ pfuma.BQ zvimiro zvine kuomarara kwepamusoro zvakati zvakanaka.
③ Kune iyo yakadzika-yakadhonzwa chigadzirwa, madiki madiki makwapa uye RIDGING anozoonekwa pamusoro penzvimbo ine huwandu hukuru hwedeformation, zvichikanganisa kuita kweBQ.
4. Kudzivisa kupisa
Kupisa kupisa kunoreva kuti simbi isina tsvina inogona kuramba ichichengetedza yakanakisa yemuviri uye michina zvimiro pakupisa kwakanyanya.
Mhedzisiro yekabhoni: Carbon inoumbwa zvakasimba uye yakagadzikana mu austenitic stainless steels.Zvinhu zvinosarudza austenite uye kuwedzera austenite dunhu.Kugona kwekabhoni kugadzira austenite kunosvika makumi matatu kune iyo nickel, uye kabhoni chinhu chinopindirana chinogona kuwedzera zvakanyanya simba reaustenitic stainless simbi kuburikidza nekusimbisa mhinduro yakasimba.Kabhoni inogona zvakare kunatsiridza kushushikana kwecorrosion kuramba kweaustenitic Stainless simbi mune yakanyanya kunyudzwa chloride (senge 42% MgCl2 kuvira mhinduro).
Nekudaro, mu austenitic stainless simbi, kabhoni inowanzoonekwa sechinhu chinokuvadza, kunyanya nekuti pasi pemamwe mamiriro (akadai sewelding kana kupisa pa450 ~ 850 ° C) mukupokana nekuora kwesimbi isina tsvina, kabhoni inogona kudyidzana nekabhoni mumhepo. simbi.Chromium inoumba yakakwira-chromium Cr23C6-mhando kabhoni makomisheni, izvo zvinotungamira mukuderera kwechromium yemuno, iyo inoderedza kushorwa kwesimbi, kunyanya kuramba kune intergranular corrosion.naizvozvo.Mazhinji ezvichangobva kugadzirwa chromium-nickel austenitic Stainless steels kubva kuma1960s akanyanya-yakaderera kabhoni marudzi ane kabhoni ari pasi pe0.03% kana 0.02%.Zvinogona kuzivikanwa kuti sezvo kabhoni yemukati inoderera, iyo intergranular corrosion susceptibility yesimbi inoderera.Kana iyo kabhoni yemukati yakadzikira kupfuura 0.02% ine yakanyanya kujeka mhedzisiro, uye zvimwe zviedzo zvakaratidzawo kuti kabhoni inowedzerawo gomba corrosion maitiro echromium austenitic simbi isina tsvina.Nekuda kwekukuvadza kwekabhoni, kwete chete kabhoni yemukati inofanirwa kudzorwa zvakaderera sezvinobvira mukunyungudutsa kweaustenitic stainless simbi, asiwo mune inotevera nzira yekupisa, kutonhora kushanda uye kupisa kurapwa kudzivirira kuwedzera kwekabhoni pa. pamusoro pesimbi isina tsvina uye kudzivirira chromium carbides Precipitate.
5. Corrosion resistance
Kana huwandu hwemaatomu echromium musimbi isiri pasi pe 12.5%, simba re electrode resimbi rinogona kungoerekana rachinjwa kubva pakusakwanisa kuita maelectrode akanaka.Kudzivirira electrochemical corrosion.
Kuchenesa nzira yepombi yesimbi isina tsvina
1. kushandiswa kwekutanga kwekunyungudutsa kuchenesa simbi, pamusoro peiyo organic kubviswa,
2. wobva washandisa maturusi ekubvisa ngura (waya bhurasho), bvisa yakasununguka kana kuti tilt scale, ngura, welding slag, nezvimwewo,
3. kushandisa pickling.
Nzira yekubatanidza
Pane kazhinji nzira ina dzekubatanidza pombi dzesimbi isina tsvina:
1. Compression connection---------Iyo yakakamurwa kuita imwechete compression uye kaviri compression.Kaviri clamping ndiyo yakatsiga yekubatanidza nzira.Shandisa radial shrinkage yekunze simba (hydraulic pliers) kusungirira pombi papombi, uye kupfuudza kumira kwemvura kweO-ring kuti uwane mhedzisiro yekubatanidza.Chiri nyore kushanda, chisimbiso chakanaka uye chisingabvisike.
2. Mhete yekuwedzera yekubatanidza---------Shandisa radial contraction yekunze simba (hydraulic pliers) kusungirira pombi papombi, uye kupfuudza kumira kwemvura kwehupamhi bhendi rekuvhara rubber yekuisa chisimbiso kuti uwane iyo yekubatanidza maitiro, inobviswa, pombi Maitiro e kuisa uye kuwedzera rolling convex mhete yepombi yekupedzisira;iyo yekuisa chisimbiso ndeyese, uye mutengo wekukanda pombi fittings wakakwira.
3. Welded kubatana---------Kupisa-kunyunguduka maitiro kunoshandiswa kubatanidza zvikamu zviviri zvinobatanidza kuti zviwane mhedzisiro yekubatanidza.Simba rekubatanidza rakakwirira, uye zvakaoma kuti gasi redziviriro yewelding seam isvike pachiyero, iyo inoita kuti welding seam ive nyore kuita ngura, iyo inoderedza zvakananga hupenyu hwebasa repombi;iyo yekuisa mhando inoenderana zvakanyanya nehunyanzvi hwevashandi vewelding, uye mhando yacho yakaoma kudzikamisa
4. Kuzvivharira kubatana---------kutanga kushandiswa kwediki-diameter yepurasitiki hose yekubatanidza, kukurumidza kuisirwa pasina maturusi.Iko mukati meiyo interface iri nyore kusunungura uye kudonha, uye yekuisa chisimbiso haina kunaka.
