Which standard applies to heat exchangers with a diameter of 3300 mm?
Thread Content
Heat exchangers with a diameter of 3300 mm, per GB151, up to a diameter of 2600 mm.
The diameter can be increased, and the PD product requirement can be met.
It goes beyond the scope of the standard series; it should be considered a non-standard device that requires separate design.
Doesn’t GB151 state that heat exchangers whose nominal diameter exceeds 2600 can also be designed and manufactured in accordance with this standard?
It can be designed and manufactured with reference to GB151.
Design and manufacturing can still be carried out with reference to GB151
It is designed and manufactured in accordance with GB151; I have designed ones with a diameter of 3000, and SW6.0 can be used for the calculations.
