YB/T 4173 is a standard that specifies the requirements for forged and bored seamless steel pipes with heavy wall used in high-temperature service. These pipes are designed to withstand elevated temperatures and are commonly used in industries such as power generation, petrochemicals, and refineries.
The key features of YB/T 4173 seamless steel pipes include high strength, exceptional heat resistance, and excellent weldability. This standard ensures that the pipes meet the necessary quality and performance standards required for high-temperature applications.
The chemical composition of YB/T 4173 seamless steel pipes is an essential aspect that determines their mechanical properties. The table below presents the typical chemical composition of these pipes:
Element | C | Si | Mn | P | S | Cr | Mo |
---|---|---|---|---|---|---|---|
Composition | 0.35-0.42 | 0.17-0.37 | 0.50-0.80 | ≤0.030 | ≤0.030 | 0.80-1.10 | 0.15-0.25 |
The mechanical properties of YB/T 4173 seamless steel pipes are crucial for assessing their suitability for high-temperature applications. The table below highlights the typical mechanical properties:
Property | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
---|---|---|---|
Minimum Value | 470 | 280 | 20 |
YB/T 4173 includes several steel grades suitable for forged and bored seamless steel pipes with heavy walls for high-temperature service. The most commonly used steel grade is Grade 20G. Other grades, including 12CrMoVG, 15CrMoG, and 35CrMoV, can also be used depending on the specific application requirements.
YB/T 4173 forged and bored seamless steel pipes with heavy wall are widely utilized in various high-temperature applications. These include but are not limited to:
While YB/T 4173 provides specific grades suitable for high-temperature service, alternative steel grades can also be used, depending on the application requirements and local standards. Some of the possible alternative grades are:
