12Cr1MoVG seamless pipe is a kind of seamless boiler steel tube, which is made of 12Cr1MoVG. 12Cr1MoVG seamless pipe is mainly used for boiler equipment, and the executive standard is GB / T5310.

12Cr1MoV seamless pipe is only one "G" less than 12Cr1MoVG seamless pipe in material. The "G" is not a chemical element, but the first letter of Chinese phonetic alphabet of boiler. 12Cr1MoV seamless pipe is alloy pipe and cannot be used for pressure bearing.

The chemical elements are analyzed and compared between 12Cr1MoVG seamless pipe and 12Cr1MoV seamless pipe as follows:
The chemical composition of 12Cr1MoVG seamless pipe: C: 0.08 - 0.15, Si: 0.17 - 0.37, Mn: 0.40 - 0.70, Mo: 0.25 - 0.35, Cr: 0.90 - 1.20, V: 0.15 - 0.30.

The chemical composition of 12Cr1MoV seamless pipe: C: 0.07 - 0.15, Si: 0.18 - 0.37, Mn: 0.41 - 0.70, Cr: 0.90 - 1.20, Mo: 0.25 - 0.35, V: 0.15 - 0.30.

12Cr1MoVG seamless pipe has an obvious advantage, that is, it can be recycled 100%, which is in line with the national strategic concept of environmental protection and energy saving.
