2、鍍鋅鋼管管口對接后出現(xiàn)兩支管口對接不嚴現(xiàn)象，導致焊口薄厚不均勻；以及鋼管由于本身原因或運輸磕碰，造成管口橢圓，建議將鋼管管頭截掉一小段兒后再進行加工。 </p> <p> 3、鍍鋅鋼管管口對接后，管口部位出現(xiàn)砂眼： </p> <p> 4、焊接時由于技術(shù)原因造成。 </p> <p> 5、管口存在鋅瘤，造成焊接困難和砂眼問題，對鋅瘤過大、過多管進行簡單的鋅瘤去除處理。 </p><p> 螺旋管道的連接工藝有哪些？ </p> <p> 1、鋼管對焊 </p> <p> （1）將要對接的兩根鋼管放在同一平面的同一軸線上。 </p> <p> （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，應在焊接完成后24小時內(nèi)進行。 </p> <p> 2、法蘭連接 </p> <p> （1）金屬法蘭套在連接件上，并對兩個相應的連接件進行校正，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。擰緊的螺栓應露出螺母，并應齊平。螺栓帽應鍍鋅。 </p> <p> （3）連接管的長度應準確，擰緊螺栓時不應引起管的軸向拉力。 </p> <p> （4）法蘭連接處設(shè)有支架。 </p> <p>

鋼材力學性能是保證鋼材較終使用性能（機械性能）的重要指標，它取決于鋼的化學成分和熱處理制度。在鋼管標準中，根據(jù)不同的使用要求，規(guī)定了拉伸性能（抗拉強度、屈服強度或屈服點、伸長率）以及硬度、韌性指標，還有用戶要求的高、低溫性能等。 </p> <p> 抗拉強度（σb） </p> <p> 試樣在拉伸過程中，在拉斷時所承受的較大力（Fb），除以試樣原橫截面積（So）所得的應力（σ），稱為抗拉強度（σb），單位為N/mm2（MPa）。它表示金屬材料在拉力作用下抵抗破壞的較大能力。鍍鋅鋼管鍍鋅可增加鋼管的抗腐蝕能力，延長使用壽命。馬鞍山無縫管生產(chǎn)廠家</p><p
