Seamless square tube Performance Analysis: Performance index [1] Analysis of seamless square tube - plastic plastic refers to the metal under load, plastic deformation (permanent deformation) without the ability to damage. [2] Pedigree Liaocheng seamless square tube plant seamless square tube performance index analysis - hardness hardness is a measure of the hardness of the metal material pointer. Production method for measuring the hardness currently most common method is the indentation hardness, it is certain geometry indenter under a certain load is pressed into the surface of a metallic material to be tested, to determine the hardness value according to the degree of being pushed. Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV) and other methods commonly used method. The performance index [3] seamless square tube analysis - discussed earlier fatigue strength, ductility, hardness metal mechanical performance indicators are under static loads. In fact, many machine parts are working under cyclic loading, part under such conditions will produce fatigue. Passers-shaped pipe should also have other cross-sectional shape. 1] 20 # seamless square tube production processes from the classification of the pipe divided by the production process: hot-rolled seamless pipe, cold drawn seamless pipe, extruded seamless pipe, welded square tube. Welded square tube which is divided into: (a) according to process sub - arc welding pipe, ERW square tube (high frequency, low frequency), welding pipe, square tube furnace brazed (b) by weld points - straight seam welded pipe, spiral welded square tube [2] 20 # seamless square tube material classification from the pipe Material: carbon steel square tube, low-alloy square tube. Carbon steel is divided into: Q195, Q215, Q235, SS400,20 # steel, 45 # steel; low-alloy steel into Q345,16Mn, Q390, ST52-3 like. [3] square tube square tube production standards classify points according to production standards: GB square tube, the standard square tube, inch square tubes, American standard tube, square tube European standard, non-standard square tube. [4] square tube classify the pipe cross-sectional shape by cross-sectional shape classification: (1) simple section square tube - square pipe, rectangular square tube (2) complex section square tube - flower-shaped square tube, square tube-shaped opening, corrugated shaped square tube, shaped square tube [5] square tube square tube classify surface treatment divided by the surface treatment: hot dip galvanized pipe, galvanized pipe, oiled square tube, square tube [6] pickling square tube use classification party By Application tube - decorative square tube, square tube with machine tools, industrial machinery square pipe, chemical pipe, square steel pipe, shipbuilding pipe, automobile pipe, steel beams with square tube special purpose Po square tube Liaocheng Steel Pipe Manufacturing Co., Ltd. Main square pipe, rectangular pipe, shaped steel, 16Mn seamless pipe, 20 # seamless tube moments, Q345B seamless square tube, on the 20th seamless tube moments, Q345B seamless tube moments, redrawn shaped seamless steel pipe, 16Mn seamless square and rectangular tube processing, the company produced square tube, rectangular tube with a full-size specifications: 600 * 20 * 20 --- 600 square tube, 20 * 30 --- 400 * 800 rectangular tube thickness of 1.5mm --- 32mm, up to more than 2800 kinds of specifications; made of Q195, Q215, Q235, Q275, Q345,20 #, 45 #, stainless steel, seamless pipe , alloy steel, and can produce diamond, triangular, pentagonal, hexagonal, fan and other special size, are also available according to customer drawings, dimensions tailored.
