Imiyoboro idafite ibyuma irashobora kugabanywa muri ASTM yumunyamerika usanzwe utagira ibyuma, DIN yo mu Budage isanzwe idafite ibyuma, imiyoboro y’icyuma ya JIS y’Abayapani, imiyoboro y’icyuma idafite uburinganire, imiyoboro y’icyuma ya GB, imiyoboro y’icyuma ya API hamwe n’ubundi bwoko ukurikije ibipimo byabo. ASTM Abanyamerika basanzwe bafite ibyuma bidafite ibyuma biri muri Birasanzwe mubisanzwe mumahanga kandi bifite ubwoko bwinshi namashami.
Noneho ibipimo bijyanye na ASTM umuyoboro wicyuma udafite icyuma ASTM stm a210 / a210m / astm sa210 / sa-210s Umuyoboro wumunyamerika usanzwe udafite icyuma urutonde rwibi bikurikira:ASTM A210 / A210M. Ahanini itanga amanota yicyuma: A-1, C, nibindi Nyuma yumushyikirano, andi manota yimiyoboro yicyuma nayo arashobora gutangwa.
Uburyo bwo gukora imiyoboro idafite ibyuma:
Imiyoboro idafite ibyuma igabanyijemo ibice bishyushye bidafite ibyuma, ibyuma bikonje bikonje bidafite icyuma, nibindi bikurikije inzira yabyo. Diameter yimiyoboro yicyuma idafite uburinganire muri rusange ni 406mm-1800mm, naho uburebure bwurukuta ni 20mm-220mm. Ukurikije imikoreshereze yabo, barashobora kugabanywamoimiyoboro idafite ibyuma byubatswe, imiyoboro idafite ibyuma idafite amazi, imiyoboro idafite ibyuma kubiteka, naimiyoboro idafite ibyuma imiyoboro y'amavuta.
