Seamless Pipes

Madras Steels And Tubes manufacturers Seamless Pipes. Seamless steel come in finishes such as hot rolled, cold drawn, turned, roto-rolled etc. After the end finishing, all pipe is then pressure tested on a machine. Following a final visual inspection, pipe is weighed, measured and stenciled. External coating can then be applied if required. It is involved in the applications for aircraft, missiles, anti-friction bearing, ordnance, etc. Ultra high strength and corrosion-resistant properties makes these perfect for oil & gas industry, chemical industry and car industry. Seamless steel pipes and tube comes in all kinds of sizes including thin, small, precise, slender and other special pipes and are used for steam boilers and pipelines, installations with high and supercritical steam conditions. These pipes and tubing are manufactured by commercial, electric furnace bearing, consumable, electrode vacuum melted quality steel. These impart strength and durability to the pipes and thus can be used for corrosion-resisting applications. Seamless pipe manufacturing uses hot rolled round bar billet of carbon steel or steel alloy. The billets are cut into suitable length depending on the required length of the finished tube. The billets are heated in a furnace at a temperature of 1200oC to 1300oC. Then the seamless tube is formed by drawing a solid billet over a pierce to create the hollow shell (mother blanks). These hollows are crimped at one end in hot condition and then they are air cooled.
