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.
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.Pipe classification: steel pipe seamless steel pipe and welded steel pipe (tube) two categories. It can be divided into round tube and special-shaped tube according to the sectional shape. The round steel tube is widely used, but there are some special-shaped steel tubes such as square, rectangle, semicircle, hexagon, equilateral triangle and octagon.
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.
