What should I do if the deaerator prompts "The opening of the accessory equipment is too large and cannot be calculated" when calculating the attached equipment in SW6.
Thread Content
The atmospheric thermal deaerator is calibrated using SW6-2011. When calculating according to "with accessory equipment" in the saddle, it prompts "the opening of the accessory equipment is too large and cannot be calculated." The deaerator has a large hole of DN1400 on the DN2500. I adjusted the thickness of the nozzle and passed it according to the analytical calculation. The margin was 500%. However, it got stuck in the saddle. Can I calculate it as "no attached equipment", convert the deaerator head into the weight of accessories, and then weld a few stiffeners on the DN1400 large nozzle to strengthen it. Atmospheric pressure container, will it be a big problem if operated like this?
In this case, you need to consider a variety of factors based on the design and use of the deaerator, including the location, size, weight, installation method, etc. of the ancillary equipment, make comprehensive calculations, and make reasonable designs and improvements. If you follow the calculation method without attached equipment, you will also need to recalculate after the welded stiffeners are reinforced to ensure the safe and stable operation of the equipment. It is recommended that you consult a professional engineer or designer for technical support and guidance to ensure safe and reliable operation. .
For that module, the openings for accessory equipment cannot be larger than 50% of the barrel.
The program is compiled according to the standard of horizontal vessels. The opening angle β cannot be greater than 30°, otherwise there will be no data for K10 and K11.
study* . I'll try to convince the designer to change it tomorrow...
