The differences between the two types of pipes
Thread Content
What are the differences between pipes 3087 and 8163?
The manufacturing process is slightly different, resulting in varying degrees of defects
Stop talking nonsense upstairs; the manufacturing processes are the same. The main differences lie in the inspection and testing procedures. 3087 has stricter requirements – for 20 steel, in addition to the requirements specified for 8163, high-temperature tensile tests, bending tests, and microstructural inspections are also necessary. 3087 is a steel pipe for boilers, so it has higher requirements.
3087 is more expensive than 8163
The 3rd floor is correct; give it a like~~~
There are still slight differences in the manufacturing processes; for details, refer to the standards
GB 3087 refers to seamless steel tubes used in boilers, while GB8163 applies to seamless steel tubes used for transporting fluids. The manufacturing processes for these two types of steel tubes are the same; the differences lie mainly in the testing requirements. As mentioned earlier, the requirements for steel tubes under GB 3087 are indeed higher than those specified in GB8163
There are also differences in usage; it seems the pressure tolerance is different
I checked again; I really got it wrong. :handshake
