Any codes for Hoppers and Sylos

No.

Unlike oil or water storage tanks, you have a lot of variation in construction methods, in materials stored, and in configuration.

I believe there is an ACI standard for concrete structures. And some European standards. But not ASME.

Also on many occasions we had to design Rectagnular tanks (API 650 did not help), are are some ASME equivalent for Rectangular tanks or WRC equivalents for the above.

See ASME Section VIII, Div 1, Mandatory Appendix 13 for Vessels of Noncircular Cross Section

We have over 40 large silos and a far as I can recall there was not specific code called out. The was no mention on any codes in the generation of repair orders and procedures. We also had several large rectangular Al hoppers that I know weren't built to any good codes, They required a lot of maintenance.

Here is some very general information on the construction of silos. Lemanco also makes rectangular bins.

Bin, hopper, or silo design is more on structural analysis. If there are codes for these types of storage equipment, they would probably be guidance or recommendations.

Check out the papers in this link for more guidance...

I believe there is now a silo standard in Europe..
If you still interested I will try to gather more information..
All starts with the definition of the stored product
and
classifying the silo ( depending on the weight).

Troistky's "Tubular Steel Structures" book has a chapter on
bins & bunkers, etc. round & rectangular $24 from JF Lincoln:

such a deal!!

bmoorthy....

The kind folks at Columbian TecTank have answered this question many times for steel bolted-panel and welded construction.


Generally speaking, these companies follow a group of rules and guidlines from AISC, WRC and misceelaneous reference papers.

Your question on rectangular tank design has been posted several times on this website....please do a search

(I belive that "Sylos" was a well known Greek shipping magnate in the mid-1960s)

VEDBI003 - Vessels for Bulk Solids Data Sheet

This Practice is the data sheet required to define options covered in PIP VESBI002, Design and Specification of Vessels for Bulk Solids, and other specific requirements applicable to the particular vessel under consideration for service (startup, normal operation, upset, shutdown), location, maintenance, etc. This data sheet contains sections titled "Engineering Requirements," Process Data for Contained Product," Supplementary Data to be Provided by the Supplier," Materials," Summary of References," "Engineering Notes," "Nozzle Schedule," and an area for a sketch of outlines of equipment and dimensions that the manufacturer must hold.

VESBI002 - Design and Specification of Vessels for Bulk Solids

This Practice describes the materials, design, fabrication, inspection, testing, and documentation requirements for the construction of atmospheric and low-pressure, welded, shop- and field-fabricated dry bulk solids bins, hoppers, silos, and gravity blenders for various chemical facilities. These bulk solids bins, hoppers, silos, and blenders generally meet the philosophy and requirements of Section VIII, Division 1, of the ASME Boiler and Pressure Vessel Code, henceforth referred to as the Code; however, Code inspection and stamping are not required.

This Practice designates requirements for the design and construction of welded, cylindrical shell, single-wall vessels having internal design pressures not exceeding 15 psig and/or full vacuum external pressure at the top of the vessel in its normal operating position. Data sheet PIP VEDBI003 is required to define options covered herein and other specific requirements applicable to the particular vessel under consideration for service (startup, normal operation, upset, shutdown), location, maintenance, etc.

The EC3 code has specific parts for silos and hoopers

bmoorthy,

You can use DIN 1055 Part 6 for design of circular and non-circular silos. I believe the latest edition is currently availale only in German. However, the English version of the same in the older 1987 edition is available. For the 1987 version, an addenda in the form of "Supplement 1" is available.

Hope this helps. The above info is valid for "metal" silos.
