What are the types and uses of cold-drawn seamless steel pipes
The types of cold-drawn seamless steel pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn seamless steel pipes, extruded pipes, etc. Generally speaking, if you want small size and good quality pipes, cold-drawn seamless steel pipes are rolled in the process of cold rolling, usually on a two-high mill, and the steel pipes are rolled in a ring pass composed of a variable section circular hole groove and a stationary conical head. Cold drawing is usually carried out on a single or double chain cold drawing machine of 0.5~100T. In the extrusion method, the heated tube blank is placed in the closed extrusion cylinder, and the perforating rod and the extrusion rod move together to make the extruded part extruded from the smaller die hole. This method can produce steel pipes with smaller diameters.
Cold-drawn seamless steel pipes are widely used. The cold-drawn seamless steel pipe for general purpose is rolled by ordinary carbon structural steel, low alloy structural steel or alloy structural steel, and has the largest output, mainly used as a pipeline or structural part for conveying fluids.
Supply is divided into three categories according to different uses: A. Supply according to chemical composition and mechanical properties; b, according to mechanical performance supply; c, according to water pressure test supply. Steel pipes supplied according to class a and b, such as those used to withstand liquid pressure, should also be hydraulically tested.
Cold-drawn special-shaped seamless steel pipe can be divided into oval shaped steel pipe, triangular shaped steel pipe, hexagonal shaped steel pipe, diamond shaped steel pipe, octagonal shaped steel pipe, unequal hexagonal shaped steel pipe, five-valve plum shaped steel pipe.
The factory focuses on the production of seamless steel pipe and steel pipe mechanical parts processing products, can provide customers with certain product design and solutions. The main products are: cold-drawn seamless steel pipe, fine rolled seamless steel pipe, alloy seamless steel pipe, shaped seamless steel pipe and so on.
