Spiral welded pipe

Spiral welded pipe is a special form of the structural pipe One of the few exceptions to this is spiral pipe, where steel strips are coiled and welded in a spiral pattern. The process, in turn, delivers a single strongest tube for working with — spanning multiple applications and industries. Spiral welded pipes have become a staple in the industry, given their reliability and adaptability for many types of jobs. 

When producing spiral welded pipe, first of all we need to buy high-quality coil strips. These strips are then provided to a machine after cutting, same with the SSAW For Insulated Pipes. That polyethylene is then fed into a machine known as an extruder that squirt it out in large, thin strips which are wrapped around the round mandrel to form tubes. After wrapping the strips around a mandrel, they are edge welded to form the tubing. This is to produce a long tube hundreds of meters in length. The welding method being used is called to be submerged arc welded. Essentially, the welding is done beneath a layer of protection called flux to shield the weld from air and also aid in creating an excellent bond.

The advantages and disadvantages of spiral welded pipe

One good thing about spiral welded pipe is that it can be manufactured in a variety of sizes and lengths, just like the Ruijie ERW For Steel Pipe Piles. This flexibility makes it usable for many different kinds of projects. Even more, this pipe is exceptionally strong for use on demanding jobs and heavy weights. This smooth, continuous tube is made through the welding process so there are no weak points that may become problematic down the line. 

However, there are also a handful of negatives. One example is producing spiral welded pipe, this can cost more than other forms of bonded pipes; As more expensive, this can be a problem for certain projects hoping to get up and running immediately with limited funds. The major drawback is, sometimes welding process may alter the pipe shape a little bit. These changes in properties have an impact on the total quality of pipe, and it is something that producers must consider.
