Product Description
Carbon/Alloy Seamless Steel Tube is a long hollow cylindrical element which is formed by heating the billet of alloyed steel and then passing them into a series of rollers to transform the raw material into various different sizes as per the requirement of the customer and the area of application. It is machined by using modern machines which provides high class surface finish and flawless construction. Carbon/Alloy Seamless Steel Tube can be used in applications in steam and gas pipeline for conveying various other gases or liquids in industries and other buildings. Buyers can get this heavy duty products from us in large quantities at a reasonable price.
