A wide variety of seamless pipe models are available, categorized by material, application, and standards.

As for the material, there areCarbon structural steel10# and 20# seamless pipes are commonly used for the transportation of low-pressure fluids such as water and gas.Alloy structural steel45# and 40Cr seamless tubes, suitable for mechanical processing of load-bearing parts.

In terms of application, seamless pipes used for conveying fluids include the 20# pipes according to GB/T8163 standard; while structural pipes such as the 16Mn pipes according to GB/T8162 standard are widely used in engineering structures.

High-pressure boiler seamless pipes are available in models such as 20G and 12Cr1MoVG, capable of withstanding high temperatures and pressures; for oil cracking, options include 15CrMo and 12Cr2Mo, which excel in corrosion resistance and high-temperature performance. Additionally, stainless steel seamless pipes like the 304 and 316 series are highly corrosion-resistant and suitable for chemical industries and other sectors.
