style="font-size:20px;"><strong>奧誠機械為客戶簡單介紹彎頭分類：彎頭按它的曲率半徑來分，可分為長半徑彎頭和短半徑彎頭。長半徑彎頭的曲率半徑等于</strong><strong>1.5</strong><strong>倍的管子外徑。短半徑彎頭的曲率半徑等于管子外徑</strong><strong>.R=D,</strong><strong>式中的</strong><strong>D</strong><strong>為彎頭直徑，</strong><strong>R</strong><strong>為曲率半徑。彎頭分為多種型號，最常用的型號是</strong><strong>STD</strong><strong>和</strong><strong>XS</strong><strong>兩種型號。本公司生產<a
