GB 8162 20# steel pipe is a seamless steel pipe produced in accordance with the GB 8162 standard, where "20#" indicates that the steel pipe material is No. 20 steel. No. 20 steel is high-quality carbon structural steel, which is a low-carbon steel with a carbon content of about 0.2%. It has the characteristics of low strength, good toughness, plasticity and good weldability, so it is widely used in various engineering fields.

The characteristics of GB 8162 20# seamless steel pipe are mainly reflected in the following aspects: High-quality material: 20# seamless steel pipe is made of high-quality carbon structural steel and has good mechanical properties and processing performance. Its strength is slightly higher than No. 15 steel, and it has high cold deformation plasticity. Suitable for bending, rolling, flanging, hammer arching and other processing processes. Excellent welding performance: 20# seamless steel pipe has good welding performance and is suitable for arc welding, contact welding and other processes. When gas welded, due to its small thickness, it is particularly suitable for manufacturing parts with strict appearance requirements or complex shapes. Good cutting and processing performance: 20# seamless steel pipe also has good cutting and processing performance, suitable for manufacturing products with low stress but high toughness requirements. Wide range of applications: Due to its excellent performance, GB 8162 20# seamless steel pipe is widely used in various fields of petroleum, chemical industry, electric power, machinery, construction and other industries for manufacturing pipes, containers, equipment, pipe fittings, mechanical structures, etc.

 

GB 8162 20# steel pipe is mainly used to manufacture mechanical parts, structural parts, deep drawing or inflatable parts, etc. Its excellent performance and wide range of uses make it a very popular seamless steel pipe in the market.

 

In terms of delivery status, GB 8162 20# steel pipe is usually delivered in a hot-rolled or cold-drawn state, which may differ according to user needs and contract regulations. Hot-rolled steel pipes have higher strength and toughness and are suitable for applications that withstand greater pressure and impact; while cold-drawn steel pipes have higher precision and surface quality and are suitable for applications that require higher dimensional accuracy and appearance.

 

In general, GB 8162 20# steel pipe plays an important role in many industries with its excellent performance and wide range of applications.
