Tube thiab Yeeb Nkab Kev Lag Luam Cov Lus Cim / Cov Cai

Nyob rau hauv daim teb no ntawm steel, muaj ib tug tshwj xeeb txheej ntawm acronyms thiab terminology, thiab tshwj xeeb terminology no yog tus yuam sij rau kev sib txuas lus nyob rau hauv kev lag luam thiab lub hauv paus rau kev nkag siab thiab ua tej yaam num.

Hauv tsab xov xwm no, peb yuav qhia koj txog qee qhov feem ntau siv cov yeeb nkab steel thiab tubing kev lag luam acronyms thiab terminology, los ntawm cov qauv ASTM yooj yim rau cov khoom siv nyuaj, thiab peb yuav txiav txim siab lawv ib los ntawm ib qho los pab koj tsim lub hauv paus ntawm kev paub txog kev lag luam.
