style="text-indent:25px">防腐鋼管不僅用于輸送流體和粉狀固體、交流熱能、制造機械零件和容器，它還是一種經濟鋼材，一般的防腐鋼管長度也是有數的，銜接在一起是需求節(jié)點的，而且防腐鋼管在節(jié)點結構上有著特別的要求，我們一起來看下防腐鋼管對節(jié)點構造的要求細節(jié)： 1。主管的外部尺度不該小于支管的外部尺度，主管的壁厚不該小于支管壁厚，在支管與主管銜接處不得將支管刺進主管內。 2。主管與支管或兩支管軸線之間夾角不宜小于30攝氏度。3。支管與主管的銜接節(jié)點處，除搭接型節(jié)點外，應盡可能避免偏心。4。支管與主管的銜接焊縫，應沿全周接連焊接并平滑過渡。 5。支管端部宜運用自動切管機切割，支管壁厚小于6mm時可不切坡口。公司一貫以服務榜首、質量榜首、價格合理、客戶至上、服務周到、讓利客戶、廠薄利多銷為準則，誠篤守信為宗旨。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廣東彎管官網"

1.彎管成型過程中光滑對產品質量的影響：企業(yè)在傳統(tǒng)的彎管生產工藝中，為得到更好的彎管表面質量，會采納許多的辦法，其中包括：采用更先進高（gao）擋的彎管機，用強度更高的模具，或者采用光滑產品等辦法。 2.彎管時資料外側受拉，內側受壓中性軸所在位置則與彎管辦法而不同，在頂彎式(壓縮彎曲)作業(yè)時中性軸處于離外壁約1/2處，在旋彎(回彎式)作業(yè)時，中性軸處于離外壁2/2處。因此薄壁管道彎曲，使用旋彎法是有利的。。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
