Large diameter alloy steel pipe refer to an outer diameter of 219mm or more. Because of their different manufacturing processes, they are divided into two types: hot-rolled (extruded) seamless steel pipes and cold-drawn (rolled) seamless steel pipes. Made of special alloy steel, The biggest advantage is that it can be recycled 100%.
