RHS weight formula: 4 * thickness * (side length - wall thickness) * 0.00785 circular pipe weight formula :( circumference ÷ 3.14) - thickness} * thickness * 0.02466 Note: The above unit is kg / m wherein the wall thickness and edge length in millimeters, Huainan square tube, namely mm. The following is a square tube characteristics: 1 square tube performance index analysis - strength at great speed on the load acting on the parts known as impact load, galvanized square tube price lists, the ability to destroy the metal resist the impact loading. It is called toughness. 2. Square tube performance index analysis - discussed the impact strength and toughness in front of, plastic, metal hardness are under static load mechanical function pointer. In fact, iron square tube price, many machine parts are working in reincarnation load, in this context parts will produce fatigue. 3. Square tube performance index analysis - Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV) exhausted other methods commonly used method. Hardness is a measure of the hardness of the metal material pointer. The present production method for measuring the hardness of the most commonly used method is the indentation hardness, which is a certain geometry of the 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.
