Isu tinovimba nesimba rehunyanzvi resimba uye tichigara tichigadzira matekinoroji echizvino-zvino kuti asangane nezvinodiwa neODM Manufacturer China Cold Drawn Seamless Carbon Steel Tube St52. kuti tinogona kuita zvirinani uye zvikuru.
Isu tinovimba neakasimba tekinoroji simba uye tinoramba tichigadzira tekinoroji yakaoma kuzadzisa zvinodiwaChina Seamless Simbi Tube St52, St52 Seamless Simbi Tube, Tine vashandi vanopfuura mazana maviri kusanganisira mamaneja ane ruzivo, vagadziri vekugadzira, mainjiniya ane ruzivo uye vashandi vane hunyanzvi. Kuburikidza nekushanda nesimba kwevashandi vese kwemakore makumi maviri apfuura kambani yavo yakawedzera kusimba nekusimba. Isu tinogara tichishandisa iyo "mutengi kutanga" musimboti. Isu tinogara tichizadzisa zvibvumirano zvese kusvika padanho uye saka tinonakidzwa nemukurumbira wakanaka uye kuvimba pakati pevatengi vedu. Iwe unogamuchirwa kwazvo kuti ushanyire iwe pachako kambani yedu.Tinotarisira kutanga bhizinesi rekudyidzana pahwaro hwekubatsirana uye kubudirira kubudirira. Kuti uwane rumwe ruzivo yeuka kuti usazeza kutibata..

Test Chinodiwa
Flattening bvunzo
Machubhu esimbi ane dhayamita rekunze rakakura kupfuura 22 mm uye anosvika 400 mm, uye ukobvu hwemadziro hwakakura kupfuura 10 mm hunofanirwa kuita bvunzo yekubata kumeso. Mushure mokunge sampuli dzakapetwa
Bending test
Machubhu esimbi ane dhayamita rekunze risingapfuuri 22 mm anofanira kupinda muyedzo yekukotama. Kona yekukombama i90o . Radhiyasi yekupeta ndeye 6 nguva yekunze dhayamita yechubhu yesimbi.Mushure mekupeta sampuli, hapana kutsemuka kana kutsemuka kunobvumidzwa kuoneka pamuenzaniso.
Macroscopic kuongorora
Kune machubhu esimbi anogadzirwa zvakananga nekuramba akakanda mabheti kana ingots dzesimbi, bato rinopa rinofanirwa kuvimbisa kuti hapana mavara machena, tsvina, pasi-pamusoro pemhepo mabhuru, zvigamba zvedehenya kana kuiswa pamuchinjiko-chikamu asidhi yakasanganiswa macroscopic tissue yebillet kana. simbi chubhu.
Kuongorora kusina kuparadza
Zvinoenderana nechikumbiro chebato ririkuda, izvo zvinozotaurirana pakati pevanopa nevanoda mapato uye zvichiratidzwa muchibvumirano, kutariswa kwehupenzi hwe ultrasonic kunogona kuitwa yega kune machubhu esimbi.
