The Difference and Use of ERW, LSAW and SSAW Steel Pipe

Straight seam high frequency (ERW steel pipe) is divided into induction welding and contact welding according to different welding methods, using hot rolled wide coil as raw material, after pre bending, continuous forming, welding, heat treatment, sizing, straightening, cutting Compared with the spiral, it has the advantages of short weld seam [price]Types of Oil & Gas PipesSeamless, ERW, LSAW [steel]The two main types of LSAW pipes are the longitudinal (with a single or double straight seam weld, DSAW) and the spiral type (called, HSAW, SSAW or SAWL pipe). Therefore, the difference between DSAW vs. LSAW is that DSAW pipes have a seam weld in the inside and outside of the pipe, whereas LSAW pipes have a single seam weld on the outer surface.

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. The T shape weld welding residual stress and weld metal are often in a three dimensional stress [price]What is a SSAW pipe? China steel pipelines, flanges [steel]What is a SSAW pipe?. Spiral submerged arc welded steel pipe is a kind of metal pipe with spiral seam welded by submerged arc welding technology.. SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature. All the pipes are produced according to API Spec 5L, GB/T9711.1, GB/T9711.2, ASTM A252 89 standard.

What is the Difference Between ERW, SSAW and LSAW

SSAW Steel Pipe. SSAW Steel PipeIt is a spiral submerged arc welded pipe. It has a forming angle (adjustable) with the centerline of the forming pipe when the pipe is rolled. It is welded while forming. The weld seam is a spiral. The advantage is that it can produce more than the same specification.[price]API 5L Spiral welded pipe for line pipe steel pipe, ERW [steel]Spiral welded pipe with spiral welded seam by double submerged arc welding to form the steel plates/coils into one pipe.

Steel Production Types Steel Steel Pipe Pipe For Sale

One thing professionals consider is if the steel pipe is spiral welded or straight seam welded. Others device the material based on the purpose i.e. manufacturing, agricultural, oil drilling, mining, etc. One of the most common ways to classify a welded steel pipe is to look at the process used.[price]Comparison Of ERW Steel Pipe And LSAW Steel Pipe [steel]Aug 22, 2018 · The reason for this is to take care of the spiral welded pipe manufacturers in the petroleum system. In the later stage, these spiral welded pipe manufacturers all used ERW straight seam electric resistance welded steel pipe and LSAW production line, and the amount of spiral welded pipe was smaller and smaller under the same caliber.
