STPT 370imhando yeJIS G 3456 yeJapan standard yemapombi esimbi yekabhoni, iyo inoshandiswa kumapombi ekumanikidza munzvimbo dzine tembiricha iri pamusoro pe350°C. Inogona kunge iri mapaipi asina musono kana akasungirirwa uchishandisa nzira yemagetsi yekubatanidza welding (ERW). Hunhu hwemuchina hweSTPT 370 material isimba rekudhonza re370 MPa uye simba rekugova re215 MPa.
Kana uchitsvaga mugadziri uye mutengesi wemapombi esimbi anoenderana neJIS G 3456 standard, saka isu tiri shamwari yauri kutsvaga. Taura nesu nhasi uye tichafara kukubatsira!
Yakakodzera dhayamita dzekunze 10.5 mm - 660.4 mm (6A - 650A) (1/8B - 26B).
A naB inzira mbiri dzekuratidza dhayamita yemazita muchiyero chechiJapan. Zvikuru, A inoenderana neDN, ukuwo B inoenderana neNPS.
JIS G 3456 STPT 370 inogona kugadzirwa uchishandisamusononzira yekugadzira kanawelding yekudzivirira magetsimaitiro (ERW).
Maitiro ekugadzira anoenderanawo nenzira dzakasiyana dzekupedzisa kuti dzikwanise kushanda munzvimbo dzakasiyana dzekushandisa.
