Minimum operating temperature for 8163 pipeline
Thread Content
What is the minimum operating temperature for pipe 8163? The standard doesn’t specify this. Some say it should be 0°C, while others say it should be >-20°C. Previously, we’ve been following the >-20°C guideline, but now I’m a bit confused.
Different quality grades require different specifications, right?
What material are the pipes in 8163? Appendix A of GB50316 specifies the lower limit of operating temperature; this should be considered in conjunction with the preceding provisions.
The steel pipes specified in GB/T8163 come in different materials such as 10#, 20#, Q345, etc., with varying minimum operating temperatures
