Kune 20# machubhu esimbi ane madziro makubvu anosvika 87mm, kutendeseka kwemukati kwakakosha zvakanyanya, sezvo kunyangwe kadiki kadiki nekusachena kunogona kukanganisa zvakanyanya kutendeseka kwavo uye kuita kwavo, uye kuongororwa kwe ultrasonic kunogona kunyatsoona izvi zvinogona kukanganisa.
Ultrasonic kuyedzwa, inonziwo UT, inzira isingaparadze yekuyedza iyo inoshandisa zvimiro zvekuratidzira, refraction, uye kudzoreredza mafungu e ultrasonic paanenge achiparadzira kuburikidza nechinhu kuona hurema mukati mechinhu.
Kana iyo ultrasonic wave ikasangana nekukanganisa mukati mezvinhu zvakadai sekutsemuka, inclusions kana maburi, mafungu anoratidzwa anogadzirwa, uye nzvimbo, chimiro uye saizi yehurema inogona kutariswa nekugamuchira aya anoratidzwa masaisai.
Kuburikidza nekunyatsoongorora, inova nechokwadi chekuti pombi yese yesimbi haina kukanganisa uye inoenderana zvizere nezviyero uye zvinodiwa nevatengi.
Botop inyanzvi uye yakavimbika Welded Steel Pipe inogadzira uye Seamless Steel Pipe stockist muChina, ichikupa zvigadzirwa zvesimbi pombi zvine hunhu hwakavimbika uye mutengo unokwikwidza. Tinovimbisa kutsigira sangano rechitatu rekuongorora zvinhu zvose zvatinotengesa, uye ticharonga vaongorori kuti vaongorore mapaipi esimbi zvakare apo batch rimwe nerimwe remapombi esimbi rinounzwa kuti tive nechokwadi chehutano hwepombi dzesimbi zvakare.
GB/T 8162 chiyero chakajairwa chakapihwa neChina chemapaipi esimbi asina musononokuda kwezvinangwa zvekugadzirisa. 20 # ndeye yakajairika kabhoni simbi giredhi ine yakanaka mechanical uye kugadzirisa zvivakwa, inoshandiswa zvakanyanya mukuvaka zvivakwa uye ma mechanical zvimiro.
