(1 4 brass square tube)  Square tube is an indispensable way of use in steel,Usually mainly used in steel structures、Structure curtain wall、Machine made,Building materials、Shipping airport、Liquid transportation, etc.。Square tube has a seamless slit,Divided into seamless and welded seams,Seamless square tubes are formed by extrusion of a round tube extrusion,Can be used for liquid transmission。 Sewing tubes can usually be welded by steel plates.,Usually used in steel structures, etc.,Plasticity means that metal materials are loaded in the load,Ability to slow down to produce plastic deformation(Permanent deformation)Not destroying。 Hardness is the ability to combine the hardness and softness of metal materials,Brittle steel,Over soft plasticity。 Now square tube detection,The most common method is indentation hardness detection,Squeeze by the tube tube,Measuring the extent to which the indentation is measured。 Now cold rolled square tube for steel structure engineering,Corner size and edge angle peace - neutrality has reached the level of even more than welded square。

   Square tube is a square cross-sectional light thin-walled steel pipe,Steel refrigeration curved profile。 The most common material is nowQ235,inQ235FurthermoreBCDEqual grade,Sewing tube isQ235Based on hot rolling or cold rolled steel or coil,Then by high frequency welding,This method is only suitable for normal requirements.,Usually better performance,Strong sealing,We usually use seamless round tubes,Cold rolling formation,Relative to cold rolling also has a hot rolling tube, Hot rolled ultra-thick wall tube is known to be thick,The hardness value is measured according to the degree of hardness detection。 Commonly used methods are Brinent hardness(HB),Rockwell hardness(HRA,HRB,HRC)And Vickers hardness(HV)。Well-known,Metal has a fatigue,For example, we repeatedly bent a wire,Wire break,Square tube has this characteristic, The intensity discussed above fatigue,Plasticity and hardness are indexes of metal mechanical properties under static load。 Actually,Solar power bracket,Steel structure engineering and many machine parts work under periodic load。 It used to use a certain time,Will test, under these circumstances,Parts will fatigue。So I still have to check regularly。The different use of the square tube determines the material of the square tube,The material of the square tube has created a lot of different physical and chemical properties.。So before using it, please consult a detailed profession.。
