Product Description

Product Description

SCH40 API 5L GR.B Straight seam and Spiral Welded steel pipe tube 

Straight seam pipe (ERW pipe) 
refers to a welded pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. The straight seam pipe is made by rolling a long steel strip of a certain specification through a high frequency welding unit and welding it with a straight seam.
 

Spiral welded steel pipes 
It  is a type of pipe produced by spirally bending and welding sheet metal. This production method allows for the manufacture of pipes in larger diameters and lengths.

Main applications

Because of their many differences in terms of strength, construction, and length, there will be applications where one kind of pipe performs better than the other.

 

Generally, straight welded pipes are used for lighter-weight applications due to their less robust form. This includes applications like transporting gas, plumbing, electrical conduits, and the like. This type of pipe is also cheaper than a spiral welded pipe, which can make it the more cost-effective choice for some projects. 

 

Spiral welded pipes, on the other hand, can fulfill more variations in length, thickness, and diameter. This allows it to be the better option for projects that need custom-made pipes. Furthermore, its superior strength makes it the ideal pipe for high-pressure, high-temperature applications. This includes transporting certain gasses, liquids, and oil, and use in industries like pharmaceuticals. However, it takes longer to produce, and can be more expensive to purchase.
