Billet-Heating-Mannesmann piercer-Elongator-Plug mill-Reeler-Reheating-SizerWhen a seamless pipe is made by rolling, the rolling method involves piercing the material while it is being rolled, and is suitable for mass production. The figure shows the manufacturing process used in the Mannesmann plug mill, which is a typical rolling process. The Mannesmann-type piercer reduces the material by rolls that are inclined obliquely to each other. When the round billet is rotated while being compressed in the diametric direction, the central part of the billet becomes loose, which makes it easy to pierce a hole through the center. This is called the Mannesmann effect. The pierced portion is expanded by the elongator, and the wall thickness is then thinned and elongated by the pug mill. The internal and external surfaces are smoothed by the reeler, and the final dimensional adjustments are made by the sizer.

U. S. Steel Tubular Products high frequency electric weld (ERW) line pipe and standard electric resistance weld pipe products are smoothly finished and thin-walled. They are produced by continuously forming coiled hot rolled strip into a tube and welding the longitudinal seam using high-frequency electric resistance welding. Chemical and mechanical property requirements are as prescribed by current API 5L and applicable ASTM standards.ERW standard pipe and high frequency electric-welded line pipe are widely used throughout the oil and gas industry, as well as for pipe piling and cable pipe systems. With over a century of producing steel products for the energy business, U. S. Steel Tubular Products offers a variety of manufacturing methods to produce steel pipe that can meet our clients’ specific requirements. Contact us to find the right steel for your application.

The most common stainless steels can be classified by different grades depending on their content of iron, carbon, chromium and other additives such as nickel, titanium or molybdenum.If a steel consists largely of an iron alloy, it can be assigned to the group of stainless steels.Therefore, let us focus exclusively on stainless steel.However, "ordinary" steel can also be rustproof and stainless steel can rust, in case it does not content the needed alloy.The ratio of the additives such as iron, carbon, chromium, nickel and others define the properties of the stainless steels.Furthermore, they are rather poor heat conductors and highly corrosion resistant. Stainless steel also has limited electrical conductivity unlike other types of steel.Austenitic, ferritic and martensitic steel - these are the three groups of stainless steel, the so-called structures, which mainly differ in their nickel content.The composition of the structure determines how magnetic the iron content of the corresponding stainless steel is.The processing of stainless steel can also have an influence on the magnetism of the material. 

ERW (Electric Resistance Welded) black steel pipes are widely used in various industries, including
