20# seamless pipe is made of 20 steel and is a high-quality steel pipe product. The standards for 20# seamless pipes include GB/T8162-2008, GB/T8163-2008, GB3087-2008, GB6479-2000 and GB9948-2006, etc., which are widely used to transport oil, natural gas, coal gas, water and certain solid materials, etc. field.
Compared with 15# steel, 20# seamless pipe has slightly higher strength and higher cold deformation plasticity, and is suitable for processing processes such as bending, rolling, flanging and hammer arching.
20# seamless pipe has good welding performance and is suitable for processes such as arc welding and contact welding. The thickness is small during gas welding and can be used to manufacture parts with strict appearance requirements or complex shapes. In addition, the 20# seamless pipe has good machinability and is suitable for manufacturing products with low stress but high toughness requirements. Its hardness is slightly lower than 45# seamless steel pipe.
