Steel having a hollow section whose length is much greater than its diameter or circumference. According to the section shape is divided into round, square, rectangular and shaped steel pipe; According to the material is divided into carbon structural steel pipe, low alloy structural steel pipe, Alloy Steel Pipe and composite steel pipe; According to the use, it is divided into pipeline, engineering structure, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high pressure equipment with steel pipes, etc. According to the production process, it is divided into Seamless Steel Pipe and Welded Steel Pipe, of which seamless steel pipe is divided into hot rolled and cold rolled (drawn) two kinds, welded steel pipe is divided into straight welded steel pipe and spiral welded steel pipe.

According to the company's higher debt speculation, Germany's precision machine tools will not have much growth in 2012. Hong En stated that the period of booming of the major customer industry has ended, thus predicting the sales growth of precision machine tools in 2012 was only 7%. In 2011, German precision machine tool companies achieved sales of 10.2 billion euros, a year-on-year increase of 21%. Thanks to the expansion of production in the automotive and machine tool industries, sales of cutting machine tools and fixtures have increased significantly. Process measurement and monitoring technologies have also achieved good results. Machine tools have achieved their first harvest since the financial crisis.
Steel pipe is not only used to transport fluids and powdery solids, exchange heat energy, manufacture machinery parts and containers, it is also an economic steel. The use of steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight, save 20 to 40% of metal, and can achieve factory mechanized construction. The manufacture of highway Bridges with steel pipes can not only save steel, simplify construction, but also greatly reduce the area of protective coating, saving investment and maintenance costs.
German precision machine tool sales increased 21% in 2011
A few days ago, Lothar Hung, chairman of the Association of Machine Tool Manufacturers of the German Machine Tool Manufacturers Association, pointed out that in 2011 Germany's precision machine tool manufacturers had achieved very good results and they were looking forward to another brilliant achievement in 2012.
