12Cr2MoG alloy seamless pipe is a high-pressure alloy pipe under GB/T5310 standard, mainly used for the heating surface of high-pressure boilers.
12Cr2MoG high-alloy structural pipe has good resistance to intergranular corrosion, excellent corrosion resistance and cold processing stamping performance. According to different use occasions, 12Cr2MoG high-pressure alloy pipe has different specifications and sizes. When purchasing, customers should choose appropriate specifications and sizes according to actual needs to ensure the normal operation of the pipeline system. At the same time, GNEE will also pay attention to checking the appearance quality of the pipe before the steel pipe leaves the factory, such as surface finish, wall thickness uniformity, etc.
