Pipe orders will be shipped as a combination of standard and random lengths. Shipments will consist of at least
80% standard lengths and up to 20% random lengths. Random lengths will not deviate from standard by more
than 20%.

Standard and random length will be shipped with Bell x Plain ends, except the last “make-up” length which will
be shipped with plain ends.

Note: When bolting FRP flanges to expansion joints with tie rods a steel backing ring is recommended
behind the full face flange (see pg 8.). For 8"-12" flanges a back-faced flange must be specified
(Standard 8"-12" flanges are spot faced for washers).

When attaching flange plate supports to flanges, back-faced flanges must be specified for 8”-12”.

To calculate L 1
Read nozzle length N1 for nozzle inside diameter D1
then L1 = N 1+ 0.5 D 2
Read mainline length N2 for mainline inside diameter D2
The same procedure is used for calculating L2
L 2= N 2+ 0.5 D 1

FABRICATION TOLERANCES
Scope B. Center Line Tolerances
This standard covers general pipe shop fabricating tolerances for For fittings that must conform to face-to-centerline dimensions, the
prefabricated piping assemblies allowable tolerance is:
A. Linear Tolerances ±1/8” up to and including 12”Ø
A.1 The tolerances on linear dimensions (intermediate or overall) ±3/16” for 14”Ø and larger
apply to the face to face, face to end, and end to end measure-
C. Flange Tolerances
ments of fabricated straight pipe and headers; center to end
or center to face of nozzles or other attachments; or center to C.1 The flange face shall be perpendicular to the axis of the fitting
face of bends as illustrated on fig. 1. These tolerances are not within 1/2° and shall be flat to within 1/32” up to and including
cumulative. 24ӯ. For diameters greater than 24ӯ, the flange face shall be
perpendicular to the axis of the fitting within ¼°, and shall be
A.2 Linear tolerances on ‘A’ are ± 1/8” for sizes 10” and under and ±
flat with 1/16”.
3/16” for sizes 12” thru 36”.
C.2 Rotation of flanges from the indicated position measured as
A.3 Linear tolerances on ‘A’ for sizes over 36” are subject to toler-
shown in fig. 1, 1/16” maximum.
ances of ± ¼”, increasing by ± 1/16” for each 12” in diameter
over 36”. D. Angles
A.4 Due to the cumulative effects of tolerances on fittings or flanges, ±1/2° up to and including 24”Ø
when joined without intervening pipe segment, deviations in
±1/4° for larger than 24”Ø
excess of those specified in paragraphs A.2 and A.3 may occur

Wall Thickness Minimum thickness, except for pre-tapered ends: same as pipe. No
maximum thickness can be stated, as reinforcement required to give the
necessary strength varies substantially over the surface of the fittings
(reference individual manufacturing specifications for part thickness).
