Stainless steel pipe OD and wall thickness explained
The national standard thickness of stainless steel pipes is determined primarily by the nominal diameter (DN) or outer diameter (OD). In Chinese GB standards, thin-wall stainless steel pipes are classified into Ⅰ series and Ⅲ series. Even with the same nominal diameter, the actual outer diameter may vary slightly between different series.

25MnG high-pressure boiler steel tubes
SA-210C (25MnG) is a seamless carbon-manganese steel tube specified under the ASME SA-210 standard, designed primarily for use in boilers and superheaters. As a pearlitic heat-resistant steel, it offers an excellent balance of strength, ductility, and thermal stability. In 1995, China incorporated this material into the GB5310 standard under the designation 25MnG, refining its chemical limits to enhance weldability and structural stability. By controlling carbon content (≤0.30%) and increasing manganese levels, 25MnG achieves superior mechanical strength while maintaining good plasticity, making it a core material for high-pressure boiler applications.
