As a professional boiler steel pipe exporter, GNEE's 20# boiler steel pipe is mainly made of 20# carbon structural steel, which has good mechanical properties and corrosion resistance. It is mainly used to manufacture various structural low- and medium-pressure boiler superheated steam pipes, boiling water pipes, and locomotive boiler superheated steam pipes, large smoke pipes, small smoke pipes, and arch brick pipes.
The outer diameter range of 20# seamless steel pipes is large, ranging from small diameter capillaries to large diameter pipes with a diameter of several meters, but the common specifications are outer diameters of 10 to 426mm and wall thicknesses of 1.5 to 26mm. The specific specifications and models can be selected according to the actual needs of customers, and ensure that their quality meets the standard requirements. And after proper treatment (such as galvanizing, plastic spraying, etc.), its corrosion resistance can be enhanced and it is suitable for various corrosive environments.
