Scope

Keeb kwm tau pom zoo xyoo 1936, qhov kev qhia tshwj xeeb no tau siv ntau hauv kev siv roj av thiab tshuaj siv tshuaj. ASTM tus qauv npog cov hlau alloy thiab stainless hlau bolting cov ntaub ntawv rau kev pabcuam kub. Cov kev qhia tshwj xeeb no suav nrog cov fasteners npaj rau siv hauv cov hlab ntsha siab, li qub, flanges, thiab fittings. Txawm hais tias, cov khoom siv no feem ntau muaj nyob rau hauv lub teb chaws ntxhib (UNC) xov pitches, yog tias siv rau hauv cov ntawv sau ib txwm, cov xov tau teev 8 threads ib nti (tpi) rau diameters saum ib nti.

Hauv qab no yog cov ntsiab lus tseem ceeb ntawm ob peb ntawm cov qib sib xws. ASTM A193 npog ntau lwm cov qauv kev qhia tshwj xeeb uas tsis suav nrog hauv cov lus piav qhia no suav nrog B5, B6, thiab B16.
