Welded Steel Pipe vs. Seamless Pipe | St. Louis Pipe & Supply
The internal surface of welded tubes can be checked before manufacturing, which isn’t possible with seamless. Advantages Of Seamless. The main perceived advantage of seamless pipes is that they don’t have a weld seam. Traditionally, the seam of welded pipes has been viewed as a weak spot, vulnerable to failure and corrosion.
Welded steel pipe - zssteeltube
Spiral Welded pipe Spiral Welded steel pipe The steel strip of low carbon structure or low alloy structure steel is rolled into tube blank at a certain spiral angle (called forming angle), and then welded together. It can be used to produce large diameter steel pipe with narrow strip steel.

Spiral Steel Pipe
The Advantages of Spiral Steel Pipe Strength Update: 2016-11-10 View(s): 550 Keywords : Pipe under internal pressure, usually on the wall there are two main stress, namely the radial stress delta Y and delta X axial stress.
What Are Differences Between Spiral Welded Pipe and ...
The welding process of spiral tube, straight seam steel pipe welding methods are varied from the previous process. So the probability of the presence of welding defects also greatly improved. The straight seam pipe will inevitably be a lot of T-weld.
Pipe under internal pressure, usually on the wall there are two main stress, namely the radial stress delta Y and delta X axial stress. Synthetic stress of the weld of the delta delta Y = (l / 4 sin2 alpha + cos2 alpha) 1/2, among them, the alpha for spiral welded pipe weld spiral Angle.
