Where is the difference between seamless steel pipe and welded pipe

Where is the difference between seamless steel pipe and welded pipe?

Answer:

In appearance, seamless steel pipe and welded steel pipe difference in the welded pipe wall welded tendons, and seamless No.
Seamless steel tube is formed during rolling. Welded steel pipes need to be welded after coiling, and spiral welding and direct welding are generally used. Seamless performance is better, of course, the price is higher.
Seamless pipe pressure is higher, welded pipe is generally in 10 or so MPa, now welded pipe to do seamless processing.
The steel tube is a hollow steel strip, used as pipe conveying fluid, such as oil, gas, water, gas, steam, in addition, the bending and torsional strength of the same, the weight is light, so it is widely used in the manufacture of machinery parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
