1.外观上,无缝钢管和焊接钢管区别在焊管内壁有焊筋,而无缝的没有。

1. in appearance, the seamless steel pipe and welded pipe are distinguished from the welded pipe on the inner wall of the welded pipe, but the welded pipe is seamless.

2.无缝管压力更高,焊管一般在10个左右MPa,现在焊管有做无缝化处理的。

2. seamless tube pressure is higher, welding pipe is generally in about 10 MPa, now welded pipe has seamless processing.

3.无缝钢管是在轧制中一次成型的。焊接钢管需要卷制后焊接而成,一般有螺旋焊和直焊。性能无缝管要好一些,当然价也高一些。

3. seamless steel pipe is formed in a rolling process. Welded steel pipes need to be rolled and welded, usually with spiral and straight welding. The performance seamless tube is better, and of course the price is higher.

钢管是一种中空的长条钢材,大量用作输送流体的管道,如石油、天燃气、水、煤气、蒸气等,另外,在搞弯、抗扭强度相同时,重量较轻,所以也广泛用于制造机械零件和工程结构。也常用作生产各种常规武器、枪管、炮弹等。

Steel pipe is a hollow strip steel, which is widely used as a conduit for transporting fluids, such as petroleum, natural gas, water, gas and steam. In addition, it is lighter in bending and torsional strength, so it is also widely used in manufacturing mechanical parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.

钢管分无缝钢管和焊接钢管(有缝管)两大类。按断面形状又可分为圆管和异形管,广泛应用的是圆形钢管,但也有一些方形、矩形、半圆形、六角形、等边三角形、八角形等异形钢管。

The steel pipe seamless steel pipe and welded steel pipe (seamed pipe) two categories. According to the shape of the section, it can be divided into circular pipes and special-shaped pipes. The circular steel tubes are widely used, but there are also some square, rectangular, semi-circular, hexagonal, equilateral triangles, octagonal and other special-shaped steel tubes.
