Welding treatment of thick-walled spiral steel pipe
Thick-walled spiral steel pipe is a method of arc welding under the flux layer. It is formed by using the heat generated by the arc burning between the flux and the welding wire under the flux layer, the base metal, and the melted welding wire flux. During use, the main stress direction of thick-...Read more -

The difference between galvanized steel pipe and hot-dip galvanized steel pipe
A galvanized steel pipe is generally called a cold-plated pipe. It adopts an electroplating process and only the outer wall of the steel pipe is galvanized. The inner wall of the steel pipe is not galvanized. Hot-dip galvanized steel pipes use a hot-dip galvanizing process, and the inner and oute...Read more -
The problem of uneven thickness of anti-corrosion coating on spiral steel pipes and how to deal with it
Spiral steel pipes are mainly used as fluid pipes and piling pipes. If the steel pipe is used for water drainage, it will generally undergo anti-corrosion treatment on the inner or outer surface. Common anti-corrosion treatments include 3pe anti-corrosion, epoxy coal tar anti-corrosion, and epoxy...Read more
