Cold drawn welded pipe is made of seamless hot-rolled steel pipe and straight-slot welded pipe as a blank. Cold drawing refers to the method of applying a pulling force on one end of the material to pull the material through a mold hole. Welded pipe is made by forming flat products (strip, sheet or plate) into the desired shape, in this case, normally round. Welded pipes can be produced in large sizes without any size restriction. The pipe has high strength. The cold drawn welded pipe is made for commercial uses.
A cold drawn welded (CDW) pipe is a kind of steel pipe that is fabricated utilizing the cold drawing process followed by welding. This interaction includes pulling a strong steel bar or billet through a pass on to shape it into a cylinder, and afterward welding the edges together to make a persistent length of line. Cold drawn welded pipes offer benefits like exact aspects, smooth surface completion, and worked on mechanical properties.
A cold drawn welded (CDW) pipe is a steel pipe that is made by first cold drawing a strong steel pole or billet through a bite the dust to accomplish the ideal aspects, and afterward welding the edges of the drawn cylinder to make a consistent appearance.
Indeed, cold drawn welded pipes can deal with moderate to high tensions and temperatures, contingent upon the particular grade of steel utilized and the wall thickness of the line.
Cold drawn welded pipes can be utilized in different conditions, yet for destructive circumstances, it's essential to consider the erosion obstruction of the steel grade utilized or apply reasonable defensive coatings.
