  • 直缝焊钢管的生产工艺是什么呢?
  • 本站编辑:杭州双惠金属材料有限公司发布日期:2019-10-13 15:44 浏览次数:

 直缝焊钢管生产工艺简单,生产效率高,成本低,发展较快。螺旋焊管的强度一般比直缝焊管高,能用较窄的坯料生产管径较大的焊管,还可以用同样宽度的坯料生产管径不同的焊管。但是与相同长度的直缝管相比,焊缝长度增加30~100%,而且生产速度较低。

 因此,较小口径的焊管大都采用直缝焊,大口径焊管则大多采用螺旋焊。

  1.低压流体输送用焊接钢管(GB/T3092-1993)也称一般焊管,俗称黑管。是用于输送水、煤气、空气、油和取暖蒸汽等一般较低压力流体和其他用途的焊接钢管。钢管接壁厚分为普通钢管和加厚钢管;接管端形式分为不带螺纹钢管(光管)和带螺纹钢管。钢管的规格用公称口径(mm)表示,公称口径是内径的近似值。习惯上常用英寸表示,低压流体输送用焊接钢管除直接用于输送流体外,还大量用作低压流体输送用镀锌焊接钢管的原管。

  2.低压流体输送用镀锌焊接钢管(GB/T3091-1993)也称镀锌电焊钢管,俗称白管。是用于输送水、煤气、空气油及取暖蒸汽、暖水等一般较低压力流体或其他用途的热浸镀锌焊接(炉焊或电焊)钢管。钢管接壁厚分为普通镀锌钢管和加厚镀锌钢管;接管端形式分为不带螺纹镀锌钢管和带螺纹镀锌钢管。钢管的规格用公称口径(mm)表示,公称口径是内径的近似值。习惯上常用英寸表示,如11/2 等。

  3.普通碳素钢电线套管(GB3640-88)是工业与民用建筑、安装机器设备等电气安装工程中用于保护电线的钢管。

  4.直缝电焊钢管(YB242-63)是焊缝与钢管纵向平行的钢管。通常分为公制电焊钢管、电焊薄壁管、变压器冷却油管等等。

Straight welded steel pipe production process is simple, high production efficiency, low cost, rapid development. The strength of helical welded pipe is generally higher than that of straight welded pipe, and larger welded pipe can be produced with narrower billets and different welded pipe diameters with the same width billets. However, compared with straight seam tubes of the same length, the weld length increases by 30~100%, and the production speed is lower.

Therefore, the welding pipe with smaller diameter is mostly straight seam welding, while the welding pipe with larger diameter is mostly spiral welding.

1. Welded steel pipe (GB/ t3092-1993) for low pressure fluid transportation is also known as general welded pipe, commonly known as black pipe. It is used for conveying water, gas, air, oil, heating steam and other general low pressure fluid and other USES of welded steel pipe. The wall thickness of steel pipe is divided into ordinary steel pipe and thickened steel pipe. The form of pipe end is divided into non - rebar tube (light tube) and rebar tube. The specification of the steel pipe is expressed in nominal diameter (mm), which is an approximation of the inner diameter. It is customary to use inches to express that the welded steel pipe used for low-pressure fluid transportation is not only directly used for fluid transportation, but also used in large quantities as the original pipe of galvanized welded steel pipe used for low-pressure fluid transportation.

2. Galvanized welded steel pipe (GB/ t3091-1993) for low-pressure fluid transportation is also known as galvanized welded steel pipe, commonly known as white pipe. It is used for conveying water, gas, air oil, heating steam, warm water and other general low pressure fluid or other USES of hot dip galvanized welding (furnace welding or electric welding) steel pipe. The wall thickness of steel pipe is divided into ordinary galvanized steel pipe and thickened galvanized steel pipe. The pipe end is divided into galvanized steel pipe without thread and galvanized steel pipe with thread. The specification of the steel pipe is expressed in nominal diameter (mm), which is an approximation of the inner diameter. Customary use of inches, such as 11/2.

3. Ordinary carbon steel wire sleeve (gb3640-88) is a steel tube used to protect electric wires in industrial and civil construction, installation machinery and equipment and other electrical installation projects.

4. Straight welded steel tube (yb242-63) is a steel tube with longitudinal parallel weld. It is usually divided into metric welded steel tube, welded thin wall pipe, transformer cooling pipe and so on.

The above is for everyone to share the content of straight seam welded steel pipe, more content welcome you to consult hangzhou shuanghui metal materials co., LTD.
