Kune machubhu esimbi ane 20# ane ukobvu hwemadziro hunosvika 87mm, kusimba kwemukati kwakakosha zvikuru, sezvo kunyangwe mitswe midiki uye tsvina inogona kukanganisa zvakanyanya kusimba kwechimiro chavo uye mashandiro avo, uye kuyedzwa kwe ultrasound kunogona kuona zvinobudirira zvikanganiso izvi zvinogona kuitika.
Kuyedzwa kweUltrasonic, kunonziwo UT, inzira yekuedza isingaparadze inoshandisa hunhu hwekuratidzira, kudzoreredza, uye kuderedza mafungu eUltrasonic sezvaanopararira kuburikidza nechinhu kuti aone zvikanganiso zviri mukati mechinhu.
Kana mafungu e ultrasonic akasangana nezvikanganiso mukati mezvinhu zvakaita sekutsemuka, zvinhu zvinosanganisirwa kana maburi, mafungu anoratidzwa anogadzirwa, uye nzvimbo, chimiro nehukuru hwemafungu acho zvinogona kutsanangurwa nekugamuchira mafungu aya anoratidzwa.
Kuburikidza nekuongorora kwakanyatsojeka, zvinoita kuti pombi yesimbi yese isakanganiswe uye inoenderana zvizere nezvinodiwa nevatengi.
Botop inyanzvi uye yakavimbika mugadziri weWelded Steel Pipe uye mutengesi weSeamless Steel Pipe muChina, ichikupa zvigadzirwa zvesimbi zvemhando yepamusoro uye mutengo unokwikwidzana. Tinovimbisa kutsigira sangano rechitatu rekuongorora zvinhu zvese zvatinotengesa, uye ticharonga vaongorori kuti vaongororezve mapaipi esimbi kana batch yega yega yemapaipi esimbi yaunzwa kuti ive nechokwadi chekuti mapaipi esimbi ari emhando yepamusoro zvakare.
GB/T 8162 ndiyo yakajairika yakatarwa neChina yemapaipi esimbi asina musonozvekuvaka. 20# imhando yakajairika yesimbi yekabhoni ine hunhu hwakanaka hwemakanika uye hwekugadzirisa, inoshandiswa zvakanyanya muzvivakwa zvekuvaka uye zvivakwa zvemakanika.
Zvinodiwa zveGB/T 8162 Giredhi 20 zvemakemikari uye zvehunhu hwemakanika ndeizvi:
