The ASTM A519 seamless steel pipe is applicable for mechanical engineering. It can be used in the transportation of steam, water, gas and so on. Its ultimate processing method of plastic deformation can be hot rolling or cold rolling. The mechanical tubing is manufactured from cast-in ingots or has received strand casting treatment.
When different grades of steel are successively strand cast, it is necessary to identify the corresponding transition material. Usually made of hot-worked steel, the seamless steel pipe does not contain any welded seam. To achieve desired shape, dimension and properties, the liquid transfer pipe may undergo hot rolling treatment. Our specialized persons may carry out heat analysis to identify the percentages of specified elements. Before shaped, the semi-finished product will be coated with an oil layer, so the seamless steel pipe does not readily rust.
