[Standardized posting guide] Issues such as aspect ratio are listed for discussion---keywords---aspect ratio---coil----please see the content

1. Within the length-to-diameter ratio L3/D, the length-to-diameter ratio is generally determined by the process. If it is determined by the design, a. Comprehensive consideration must be given to economy, b. Comprehensive consideration must be given to the stress situation for horizontal vessels, c. For mixing vessels, the effects of stirring and heat transfer must be considered. 2. The second common form is that the diameter of the coil should not be large considering the processing. The pitch is generally 1.5-2 times the diameter of the tube, which is determined according to the required heat transfer area. The coil in the mixing vessel also takes into account the fluid flow. 3. The tapered head is often used in connecting sections of different diameters and vertical containers to facilitate discharging. Spherical crown heads are often used as intermediate heads. If used as end heads, due to the relatively large local stress at the connection with the cylinder, reinforcement needs to be considered. Unless there are special needs, it is definitely not suitable. The above is just my personal opinion.

Thanks for the perfect answer, learn* .

1. For storage tanks, I may prefer L2/D in terms of length and diameter. But the height-to-diameter ratio mentioned in standards like towers may be the comparison of total height and diameter. There are recommended values ​​for the aspect ratio in some reference books. 2. The recommended spacing between coils should be recommended in the standard for mixing vessels. 3. I really didn’t notice that it wasn’t included in the software. Are things like the kettle reboiler included in the parts list?

The spherical crown head is included in the parts； The total height of the tower is equivalent to L6 in the picture, right (the supporting support is assumed to be skirt type). When calculating the conical head of a horizontal vessel according to SW6 vertical vessel, what other factors should be considered? Everyone can actively participate if you see it: handshake

Thank you friends for sharing, I have learned a lot.

Pass by, observe, learn* . After all, there are specialties in the art industry, and I am not a designer. I really don’t understand these issues. I will come to you more often to learn from you. * ,study * .

:handshake learn from each other when we are humble* Come on, come on, come on, let the pepper shine: lol

Aspect ratio, different equipment has different definitions, just follow the corresponding equipment standards. Spherical crown heads are often used as inner heads and heat exchangers in stuffing boxes. Due to structural reasons, the design pressure is relatively small, but fortunately it saves space.

1. Length-to-diameter ratio: For a mixing vessel, take the ratio of the cylinder height to the inner diameter.； In the support standards, there are also different regulations for leg supports and support supports. ； Also given in the Tower Vessel Standard. 2. Regarding the issue of screw torque, consider whether the support can be accommodated. If you simply use angle steel support, also consider whether the U-shaped bolt can be accommodated and the wrench space. ； 3. It is not known under what circumstances these two structural forms are used.
