Improve Production Technology of ERW Steel Pipe
Straight seam welded pipe (ERW straight seam welded steel pipe) is formed on the hot rolled plate of the forming machine, the skin effect and proximity effect of the high frequency current, melting of the pipe edge heating to the extrusion roller pressure welding to achieve production. The applic...Read more -
How to prevent cracking of the weld seam of high frequency welded pipe?
In high-frequency longitudinally welded pipes(ERW steel pipe), the manifestations of cracks include long cracks, local periodic cracks and irregular intermittent cracks. There are also some steel pipes that have no cracks on the surface after welding, but cracks will appear after flattening, stra...Read more -
Precautions for Purchasing Large Diameter Straight Seam Steel Pipes
Before purchasing large-diameter straight seam steel pipes (LSAW), you should follow the pre-designed specifications, lengths, materials, wall thicknesses, welding standards and weld requirements, which must be communicated well before purchasing. 1. The first is the specification. For example, 8...Read more -
How to Ensure the Quality of ERW Welded Pipe in Production?
How to reduce the wear of ERW welded pipes in production and ensure the quality of welded pipes? From the analysis data of ERW welded pipe scrap, it can be seen that the roll adjustment process plays a very important role in the production of welded pipes. That is to say, in the production proces...Read more -
Features of Hot-dip Galvanized Seamless Steel Pipe
Hot-dip galvanizing is a process in which a metal material or part with a clean surface is immersed in a molten zinc solution, and a layer of metal zinc is formed on the surface through a physical and chemical reaction at the interface. Hot-dip galvanizing, also known as hot-dip galvanizing and h...Read more
