  镀锌管是一种空心方形截面的轻型薄壁钢管,又称冷弯型钢。它是以Q235热轧或冷轧带钢或卷板为基材,经冷弯加工和高频焊接成形而成的形状和尺寸的方形截面型钢。热轧镀锌钢管除墙体加厚外,其边角尺寸及边缘平整度均可达到甚至超过电阻焊冷弯镀锌钢管的水平。主要焊接工艺为镀锌钢管焊接。

  Galvanized pipe is a kind of light thin-walled steel pipe with hollow square section, also known as cold-formed section steel. It is a square section steel with shape and size formed by cold bending and high frequency welding with Q235 hot rolled or cold rolled strip or coil as the base material. In addition to wall thickening, the edge size and flatness of hot-rolled galvanized steel pipe can reach or even exceed the level of resistance welding cold bending galvanized steel pipe. The main welding process is galvanized steel pipe welding.

  焊接镀锌钢管用较窄的毛坯来生产较大直径的焊管,也可以用相同宽度的毛坯来生产不同直径的焊管。但与相同长度的直缝镀锌钢管相比,焊缝长度增加了30~100%,生产速度降低。

  The welding galvanized steel pipe can be used to produce larger diameter welded pipe with narrow blank, or different diameter welded pipe with the same width blank. However, compared with the same length of straight seam galvanized steel pipe, the weld length increases by 30-100%, and the production speed decreases.

  大直径或较厚的焊接镀锌钢管,一般由钢坯直接制成,而小焊管薄壁焊管只需通过钢带直接焊接即可。经过简单的抛光,拉丝就完成了。因此,直径较小的焊管多为直缝焊,直径较大的焊管多为螺旋焊。综合力学性能好,可焊性好,冷、热工作性能好,耐腐蚀,具有良好的低温韧性。

  Large diameter or thick welded galvanized steel pipe is generally made of steel billet directly, while small welded thin-wall welded pipe can be directly welded by steel strip. After simple polishing, the drawing is finished. Therefore, the welded pipe with smaller diameter is mostly straight seam welding, and the welded pipe with larger diameter is mostly spiral welding. It has good comprehensive mechanical properties, weldability, cold and hot working performance, corrosion resistance and good low temperature toughness.

  镀锌钢管生产工艺简单,生产效率高,成本低,发展迅速。螺旋焊管的强度一般比镀锌钢管的强度高,可以生产直径较大、毛坯较窄的焊管,也可以生产不同直径、毛坯宽度相同的焊管。但与同长度的直管相比,焊缝长度增加了30-100%,生产速度降低。

  Galvanized steel pipe production process is simple, high efficiency, low cost, rapid development. The strength of spiral welded pipe is generally higher than that of galvanized steel pipe. It can produce welded pipe with larger diameter and narrower blank, or welded pipe with different diameter and the same blank width. However, compared with the straight pipe of the same length, the weld length increases by 30-100%, and the production speed decreases.

  因此,直径较小的镀锌管多采用直缝焊,直径较大的镀锌管多采用螺旋形镀锌钢管,根据截面积的形状,可分为圆管和异形管。由于圆的面积,周长相等,所以可以用圆管输送更多的流体。此外,环节在内外径向压力作用下,受力比较均匀,所以绝大多数钢管都是圆形的。

  Therefore, the galvanized pipe with smaller diameter mostly adopts straight seam welding, and the galvanized pipe with larger diameter mostly adopts spiral galvanized steel pipe. According to the shape of cross-sectional area, it can be divided into circular pipe and special-shaped pipe. Because the circle has the largest area and the same circumference, it can be used to transport more fluid. In addition, under the action of internal and external radial pressure, the force is relatively uniform, so most of the steel pipes are round.
