（2）保持兩管端部間隙在2-3mm之間。為保證焊接間隙距離，可在兩管間隙之間加墊。 </p> <p> （3）保證對接鋼管的坡口角度。 </p> <p> （4）鋼管焊接后30分鐘內(nèi)不得受外力移動，否則對接焊縫會開裂，影響鋼管的使用效果。 </p> <p> （5）對接焊縫如需進(jìn)行無損檢測（X射線底片或超聲波探傷），在條件允許的情況下，應(yīng)在焊接完成后24小時內(nèi)進(jìn)行。 </p> <p> 2、法蘭連接 </p> <p> （1）金屬法蘭套在連接件上，并對兩個相應(yīng)的連接件進(jìn)行校正，使兩個連接法蘭垂直于管道中心線，表面平行。 </p> <p> （2）使用同一規(guī)格的螺母，安裝方向一致，螺栓對稱擰緊。擰緊的螺栓應(yīng)露出螺母，并應(yīng)齊平。螺栓帽應(yīng)鍍鋅。 </p> <p> （3）連接管的長度應(yīng)準(zhǔn)確，擰緊螺栓時不應(yīng)引起管的軸向拉力。 </p> <p> （4）法蘭連接處設(shè)有支架。 </p> <p>
