ASTM A53 Square Tubing for structural applications
ASTM A53 Square pipe USES a construction, machinery manufacturing, steel construction projects, shipbuilding, solar power stents, steel structure engineering, electric power engineering pipe products, power plants, agricultural and chemical machinery, glass curtain wall, automobile chassis, airport, boiler building, highway railings, housing construction, pressure vessel, oil storage tanks, Bridges, power station equipment, Lifting and transportation machinery and other high load welding structures.
Classification Of ASTM A53 Square Pipe Production Process
ASTM A53 Square pipe according to the production process: hot rolled seamless square tube, cold drawn seamless square tube, squeeze seamless square tube, welded square tube.
Welding square tubes are divided into:
(a) arc welding square tubes, resistance welding square tubes (high frequency, low frequency), Gas welding square pipe, furnace welding square pipe
(b) According to the weld, it is divided into one - straight seam welded square pipe and spiral welded square pipe
Material Classification Of Astm A53 Square Pipe
Square tube according to the material: plain carbon steel square tube, low alloy square tube. Carbon steel is divided into: Q195, Q215, Q235, SS400, 20# steel, 45# steel; Low alloy steel is divided into Q345, 16Mn, Q390, ST52-3, etc.
Standard Classification Of Astm A53 Square Pipe Production
Square tube according to production standards: gb square tube, Japanese standard square tube, British system square tube, American standard square tube, European standard square tube, non the square tube.
Shape Classification Of Square Tube Section
Square pipes are classified according to section shape:
(1) simple section square pipe - - square square pipe, rectangular square pipe
(2) complex section square tube - flower shaped square tube, open square tube, corrugated square tube, shaped square tube
