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).

Extrusion or rolling: The blank tube is formed into the final shape of a seamless tube by gradually reducing the outer diameter and wall thickness through an extrusion or rolling machine. This step requires a high degree of control to ensure that the size and quality of the pipeline meet the specification requirements.Annealing: Annealing is an important heat treatment step that eliminates residual stress and improves the mechanical properties and toughness of pipelines by annealing them at high temperatures.

In addition, there are also differences in the scope of application between the two. Precision steel pipes are mainly used in fields such as mechanical manufacturing, automotive parts, industrial equipment, and high-precision instruments and meters. Due to the characteristics of high precision, high strength, and wear resistance, precision steel pipes often meet the high requirements for material performance in these fields. Ordinary steel pipes are mainly used in fields such as construction, water conservancy, energy, and chemical engineering, such as conveying fluids and structural support. In contrast, the requirements for ordinary steel pipes are relatively low and the price is relatively low.

High pressure boiler pipe is a type of pipe used for working in high-temperature and high-pressure environments. The high-pressure boiler tube manufacturer analyzes its characteristics as follows:1. Strong resistance to high pressure: High pressure boiler tubes are mainly used to carry high-pressure water vapor or other high-pressure media, so they must have high strength and compression resistance. The steel used for high-pressure boiler pipes is usually made of carbon steel, alloy steel, or stainless steel with excellent pressure resistance to ensure that the pipes will not burst or deform in high-pressure environments.
