鋼管壁厚不可能各處相同，在其橫截面及縱向管體上客觀存在壁厚不等現(xiàn)象，即壁厚不均。為了控制這種不均勻性，在有的鋼管標(biāo)準(zhǔn)中規(guī)定了壁厚不均的允許指標(biāo)，一般規(guī)定不超過壁厚公差的80%（經(jīng)供需雙方協(xié)商后執(zhí)行）。 </p> <p> 橢圓度 </p> <p> 在圓形鋼管的橫截面上存在著外徑不等的現(xiàn)象，即存在著不一定互相垂直的**大外徑和**小外徑，則比**大外徑與**小外徑之差即為橢圓度（或不圓度）。為了控制橢圓度，有的鋼管標(biāo)準(zhǔn)中規(guī)定了橢圓度的允許指標(biāo)，一般規(guī)定為不超過外徑公差的80%（經(jīng)供需雙方協(xié)商后執(zhí)行）。 </p> <p> <br />

A、局部彎曲度：用一米長(zhǎng)直尺靠量在鋼管的比較大彎曲處，測(cè)其弦高（mm），即為局部彎曲度數(shù)值，其單位為mm/m，表示方法如2.5mm/m。此種方法也適用于管端部彎曲度。 </p> <p> B、全長(zhǎng)總彎曲度：用一根細(xì)繩，從管的兩端拉緊，測(cè)量鋼管彎曲處較大弦高（mm），然后換算成長(zhǎng)度（以米計(jì)）的百分?jǐn)?shù)，即為鋼管長(zhǎng)度方向的全長(zhǎng)彎曲度。 </p> <p> 例如：鋼管長(zhǎng)度為8m，測(cè)得比較大弦高30mm,則該管全長(zhǎng)彎曲度應(yīng)為： </p> <p>

style="font-size:12px;">鍛鋼：利用鍛錘的往復(fù)沖擊力或壓力機(jī)的壓力將坯料改為所需形狀和尺寸的壓力加工方法。</span> <p> 擠壓：將金屬放入封閉式擠壓簡(jiǎn)中，在一端施加壓力，從指定的模孔中擠壓出金屬，以獲得相同形狀和尺寸的成品的一種加工方法。它主要用于生產(chǎn)有色金屬鋼。 </p> <p> 軋制：通過一對(duì)旋轉(zhuǎn)輥的間隙（各種形狀）使金屬坯料通過的壓力加工方法，由于輥的壓縮，使材料截面減小，長(zhǎng)度增加。 </p> <p> Q345B鋼管Q345A，無沖擊；Q345B，20°常溫沖擊；Q345C，0°沖擊；Q345D，20°沖擊；Q345E，40°沖擊在不同的沖擊溫度下，沖擊值不同。 </p> <p> 焊管的強(qiáng)度一般高于直縫焊管?？缮a(chǎn)直徑較大、毛坯窄的焊管，也可生產(chǎn)不同直徑、相同毛坯寬度的焊管但與同長(zhǎng)度直縫管相比，焊縫長(zhǎng)度增加了百分之三十到***，生產(chǎn)速度較低。 </p> <p>
