冷拔钢管与冷拔无缝钢管成都收账区别很多，具体分析大体分为以下几点：不同点：1.冷拔钢管是用钢板或带钢经过卷曲成型后焊接制成成都找人公司钢管。冷拔无缝钢管是用钢锭或实心管坯经穿孔制成毛管，然后经热轧、冷轧或冷拨制成。2.冷拔钢管强度低于冷拔无缝钢管。生产工艺简单，生产效率高，品种规格多，设备资少，随着焊缝质量不断提高，冷拔钢管成都收账品种规格日益增多，在很多领域代替了冷拔无缝钢管。

There are many differences between cold-drawn steel pipe and cold-drawn seamless steel pipe. Specific analysis can be divided into the following points: 1. Cold-drawn steel pipe is made of steel plate or strip welded after coiling forming. Cold-drawn seamless steel tube is made of steel ingot or solid billet through perforation and then hot-rolled, cold-rolled or cold-drawn.

2. The strength of cold-drawn steel tube is lower than that of cold-drawn seamless steel tube. With the continuous improvement of weld quality, the variety and specification of cold-drawn steel tubes are increasing, replacing cold-drawn seamless steel tubes in many fields.

3.冷拔钢管采用收账坯料是钢板或带钢，较窄成都找人公司坯料生产。

3. The blank used for cold-drawn steel pipe is steel plate or strip, which is produced with narrow blank.

4.冷拔钢管主要用于石油、天然气的输送管线。冷拔无缝钢管中空截面，重量较轻，是一种经济截面钢材，广泛用于制造结构件和机械零件，如石油钻杆、汽车传动轴、自行车架以及建筑施工中用的钢冷拔钢管等。

4. Cold-drawn steel pipes are mainly used for oil and natural gas pipelines. Cold-drawn seamless steel tube hollow section, light weight, is a kind of economic section steel, widely used in manufacturing structural and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction.

5.冷拔冷拔钢管垂直卷板轧制方向不是垂直钢管轴线方向而冷拔无缝钢管的钢板轧制方向垂直于钢管轴线方向，冷拔钢管材料的抗裂性能优于冷拔无缝钢管。

5. The rolling direction of cold-drawn steel tube vertical coil is not perpendicular to the axis of steel tube, while the rolling direction of cold-drawn seamless steel tube steel plate is perpendicular to the axis of steel tube. The crack resistance of cold-drawn steel tube material is better than that of cold-drawn seamless steel tube.

上面已经简单的为大家介绍了关于冷拔钢管与冷拔无缝钢管的区别，冷拔钢管除了上面的优点之外，还有哪些与好处呢？

The above has simply introduced the difference between cold-drawn steel pipe and cold-drawn seamless steel pipe. Besides the advantages above, what are the advantages and benefits of cold-drawn steel pipe?

冷拔钢管由于采用的坯料是钢板或带钢，具体的分类如下：

Cold-drawn steel tubes are classified as follows, because the billet used is steel plate or strip.

1.根据焊接工艺不同分为：

1. According to the different welding technology, it can be divided into:

炉焊管、电焊（电阻焊）管和自动电弧焊管。

Furnace welded pipe, electric welded (resistance welded) pipe and automatic arc welded pipe.

2.因其焊接形式的不同分为：

2. Because of its different welding forms, it can be divided into:

直缝焊管和螺旋焊管两种

Straight welded pipe and spiral welded pipe

3.因其端部形状分为：

3. Because its end shape is divided into:

圆形焊管和异型（方、扁等）焊管。

Circular welded pipe and special-shaped (square, flat, etc.) welded pipe.

20世纪30年代以来，随着焊缝质量不断提高，冷拔钢管的品种规格变得越来越多，并逐渐代替了冷拔冷拔无缝钢管，可见小口径钢管的发展势头有多大。

Since the 1930s, with the continuous improvement of weld quality, the varieties and specifications of cold-drawn steel pipes have become more and more, and gradually replaced the cold-drawn seamless steel pipes. It can be seen that the development momentum of small-diameter steel pipes is great.
