The specifications and wall thickness of seamless steel pipes vary depending on the application and requirements. The following are some examples of common specifications and wall thicknesses of seamless steel pipes, as introduced by the seamless steel pipe manufacturer:

Specification: The specifications of Jiangsu seamless steel pipes are usually defined by their outer diameter (OD) and wall thickness (WT). For example, the specification of a seamless steel pipe may be "outer diameter 60mm, wall thickness 5mm", indicating that its outer diameter is 60mm and wall thickness is 5mm. Specifications are usually in millimeters (mm) or inches (inch).

Wall thickness range: The wall thickness of seamless steel pipes can vary according to different applications and requirements. The wall thickness can be very thin or very thick to meet the strength and pressure resistance requirements of specific applications. Some common wall thickness ranges include: 1mm, 2mm, 3mm, 5mm, 10mm, etc., depending on the purpose of the pipeline.

Tolerance: The specifications of seamless steel pipes usually include tolerances on outer diameter and wall thickness. Tolerance refers to the allowable range of dimensional deviations. For example, a pipeline with a specification of "outer diameter 60mm and wall thickness 5mm" may have tolerances that allow for variations in outer diameter and wall thickness within a certain range.

Special specifications: Some applications may require seamless steel pipes of special specifications, such as high-pressure boiler pipes, oil and natural gas pipelines, chemical pipelines, etc. These special applications typically require meeting specific specification requirements.

The specifications and wall thickness of seamless steel pipes are determined based on specific applications and requirements. When selecting seamless steel pipes, it is necessary to determine the appropriate specifications and wall thickness based on the characteristics of the application, the pressure and temperature conditions they are subjected to, and other factors. Manufacturers usually provide seamless steel pipe specifications that meet international standards to meet different needs.
