</p> <p> B、實(shí)際尺寸：是生產(chǎn)過(guò)程中所得到的實(shí)際尺寸，該尺寸往往大于或小于公稱(chēng)尺寸。這種大于或小于公稱(chēng)尺寸的現(xiàn)象稱(chēng)為偏差。 </p> <p> C、米重：每米重量=0.02466*壁厚*（外徑-壁厚） </p> <p> 偏差和公差 </p> <p> A、偏差：在生產(chǎn)過(guò)程中，由于實(shí)際尺寸難于達(dá)到公稱(chēng)尺寸要求，即往往大于或小于公稱(chēng)尺寸，所以標(biāo)準(zhǔn)中規(guī)定了實(shí)際尺寸與公稱(chēng)尺寸之間允許有一差值。差值為正值的叫正偏差，差值為負(fù)值的叫負(fù)偏差。 </p> <p> B、公差：標(biāo)準(zhǔn)中規(guī)定的正、負(fù)偏差值***值之和叫做公差，亦叫"公差帶"。 </p> <p> 偏差是有方向性的，即以"正"或"負(fù)"表示；公差是沒(méi)有方向性的，因此，把偏差值稱(chēng)為"正公差"或"負(fù)公差"的叫法是錯(cuò)誤的。魚(yú)臺(tái)螺紋管供應(yīng)商鋼塑管一般用螺紋連接、溝槽連接、法蘭連接。</p><div style="width:100%;text-align: center;"><img style="max-width:
