SA573 Grade 65 specification, Welded pipe plays an important role in modern industrial production and engineering construction, and has become one of the irreplaceable steel pipe products. Welded pipe is a kind of steel pipe made of rolled plate and steel plate after crimping and forming. Therefore, the diameter of welded pipe can be made very large and can be made according to the requirements of customers. Welded pipes can be used for water diversion, transportation of gas, air, oil and heating steam and other generally lower pressure fluids.

In actual processing applications, the processing SA573 Grade 65 specification thickness of flame cutting ranges from 6 to 200 mm, and the SA573 Grade 65 specification cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting SA573 Grade 65 specification with a certain thickness above 10mm.

The chemical composition of 20CrMo steel pipe is 0.17-0.24, Si: 0.17-0.37, Mn: 0.40-0.70, Cr: 0.80-1.10, Mo: 0.15-0.25. Mechanical properties of 20CrMo steel pipe: tensile strength 410 Mpa; yield strength: 265mpa; elongation after fracture: 24; reduction of area: 60; impact absorption energy: 110J. 20CrMo steel pipe belongs to alloy structure steel pipe, which has high thermal strength, good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance at 500-520℃. SA573 Grade 65 specification, 20CrMo steel pipe is generally used in quenching and tempering state.
