[1000-pipe to introduce you to the star product - Rectangular Pipe] galvanized rectangular tube is a hollow steel bar galvanized square tube model, also known as flat tubes, flat square tube or square flat tube (as the name suggests) . A large number of pipelines for transporting fluids, such as oil, natural gas, water, gas, steam, etc. In addition, the bending and torsional strength galvanized square tube manufacturers, lighter weight galvanized pipe, so it widely used in the manufacture of mechanical parts and engineering structures. Also used in producing a variety of conventional weapons, the barrel, shells and so on. Galvanized Rectangular Pipe Rectangular Pipe production process classification 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, welded square tube furnace (b) by the weld points - Straight seam welded pipe, spiral welded square tube 2, square and rectangular tube material classification square tube Material: carbon steel pipe, low-alloy square tube. Carbon steel into: Q195, Q215, Q235, SS400,20 # steel, 45 # steel and other; low-alloy steel into Q345,16Mn, Q390, ST52-3 so on. 3, square and rectangular tube pipe production standard classifications divided by production standards: GB square tube, the standard pipe, galvanized square inch square tube heat pipe production, the US standard pipe, square tube European standard, non-standard square tube. 4, square and rectangular tube section by section shape classification square tube shape classification: (1) simple square section tube - square pipe, rectangular square tube (2) the complexity of the pipe sections - flower-shaped square tube, square tube-shaped opening, corrugated shaped square tube, shaped square tube 5, square and rectangular tube surface treatment classified according to the pipe surface treatment points: galvanized pipe, galvanized pipe, oiled square tube, square tube pickling 6, square and rectangular tube use classifications pipe by use classification - decorative square tube, square tube with machine tools, industrial machinery square pipe, chemical pipe, square steel pipe, square tube shipbuilding, automotive tube, square tube steel beams Special Purpose square tube 7, square and rectangular tube wall thickness classification Rectangular Pipe wall thickness by Category - Ultra thick-walled rectangular pipe, thick-walled rectangular pipe and thin-walled Rectangular Pipe galvanized square tube production, Yangquan galvanized square pipe, galvanized square tube thousand Tianjin Rong Rong steel provided by the Tianjin Steel Pipe Co. thousand.
