Thick Wall Steel Pipe Manufacturing Process

Generally more common punch is tapered roller punching machine, punching machine such high production efficiency, product quality, thick-walled steel, perforated expanding capacity, can be worn a variety of steel. After perforation, round tube has been three-roll rolling, rolling or extrusion. To squeeze off the pipe after sizing. Sizing mill into high-speed rotating cone drill through perforated steel embryo formed steel. Pipe inside diameter is determined by the outside diameter sizing mill drill length. After sizing the pipe into the cooling tower through spray cooling pipe after cooling, it is necessary to be straightened. After straightening the steel conveyor belt to the metal detection machine (or pressure test) for internal testing. If the internal pipe cracks, bubbles and other issues, will be detected. After the selection of steel but also through strict quality control manual. After the steel quality, spray paint on number, size, batch number and so on. By a crane into the warehouse. Features multi-walled steel production cycle of production processes, the workshop produced many varieties of steel, cold drawn seamless steel pipe in the workshop production of a product in the past, its production process must be clearly defined in advance as a, as a organization of production, production basis, this job is preparing to pull the tab. same time the turnover inherent in the workshop production of seamless steel pipe also is varied in order to make the production of such confusion does not occur, prepared well in advance rolling table is very important.The key to the number of quality thick steel wall thickness uniformity of the thickness of the thick steel pipe is not under control will directly affect the quality and usefulness, thick-walled steel pipe, large diameter thick wall steel pipe is generally used in a variety of machining, thick wall machining parts, even thick-walled steel pipe wall will directly affect the quality of post-processing of parts, thick wall pipe is not controlled, the overall quality of steel is not strict. Select the appropriate venue and custody of thick-walled steel warehouse venue or warehouse, should be selected in clean, smooth drainage area, away from harmful gases or dust in mines. Presence on the ground to be cleared of all debris and weeds, thick-walled steel pipe to keep clean. In the warehouse can not with acid, alkali, salt, cement and other thick-walled steel for corrosive materials have stacked together. Different varieties of thick-walled pipe should be stacked separately to prevent confusion and prevent contact corrosion. Large steel, rail, shame steel, large diameter seamless steel pipe, forgings, etc., may open dumps.
