New 150 regarding the material used for takeover
Thread Content
The new 150 model uses material grade 20; for grade 10, the minimum operating temperature is 0° (according to GB8163 and GB6654). At our facility, the minimum design temperature for containers is -10 degrees. I’m not sure which standard to choose besides these two; also, is it easy to obtain the materials?
Your question isn’t very clear. The minimum operating temperature for grade 10 is -10°C, while that for grade 20 is 0°C. 8163 refers to a standard for pipes, and 6654 refers to a standard for plates; there’s no way to compare them. I’m not sure how to answer this~
GB8163 will work; the minimum temperature for 10# steel pipes is -10°C, so it should be fine for your product!
The minimum temperature for 10# steel pipes per GB/T 8163 is -10°C, so they can be used. However, it shall not be used for heat exchange tubes, nor shall fittings with a steel pipe wall thickness greater than 10 mm be used.
-For 10 degrees, seamless pipes used in the fertilizer industry with a grade of 10# should be sufficient; the 8163 standard is adequate for ordinary media, while GB9948 applies for special media.
