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.

Side View
Drain fittings are generally located in one of the ends
of the tank, close to the bottom. Indicate in inches any fitting(s) that are
required in the top of the tank.
Cylindrical Open Top Tanks
Plan
View if more than one fitting is being specified, indicate in degrees the
location of the fittings.
Elevation View indicate in inches the height from center of the fitting to the
floor.
Example: Fitting A is at 180°, 15 up from
bottom; Fitting B is at 270°, 30 up from bottom.
Note 1: Use a dotted circle to indicate fittings which are on opposite side of
the elevation drawing (see fitting A )
Note 2: Never include tank flange in your measurements.
Rectangular Tanks
Indicate width, length and height of tank
using inches.
Plan View indicate in inches the distance
from edge of tank.
Elevation View indicate in inches the height from the center of the fitting to
the floor.
Example: 24 x 36 x 36 HT. Fitting is 18 in
from side along the 36 wall, 18 up from floor.
Note: Never include tank flange in your measurements
Cylindrical Cone Bottom Tanks
Plan
View if more than one fitting is being specified, indicate in degrees the
location of the fittings.
Elevation View Indicate in inches the height from the bottom of the straight
side to the center of the fitting. Do not include the cone. Stands have a lip
16 high. Consult sales office for minimum height of side fittings.
Example: Fitting A is a 0°, 15 up the
straight side; fitting B is at 90°, 20 up from straight side; C is in cone
flat.
