Specifying Fitting Locations

It is very important to be as precise as possible when specifying tank fittings and accessories. Location, type and size of fittings must be noted clearly on your drawing. If more than one fitting is being specified, mark each fitting with a letter A, B, C etc. Dimensional drawings are available for all tanks. Download a blank generic drawing and send or fax in with your order.

Vertical Bulk Storage Tanks

Plan View Calibration strip is at 0 degrees, in line with manway. Specify in degrees from 0 the location of fittings.






Elevation View Indicate in inches the height from the center of the fitting to the floor.

Example: Fitting A is at 90°, 48 up from button; Fitting B is at 180°, 30 up from bottom; Fitting C is at 270°, 20 up from bottom.
Note: Use a dotted circle to indicate fittings which are on the opposite side of the elevation drawing (see fitting B)

Most Chem-Tainer vertical storage tanks have 8 x8 flat sections at least every 90 degrees along the circumference at the bottom of the side. These flats are ideal locations for bulk head fittings.
