a. Be sure to apply the proper rupture disk to match your blow-out fitting type, see Figure 4-11, and
application pressure. Generally the rupture disk should be rated about 1000 psig (70 bar
g
)
greater than the highest MAWP cylinder.
b. See Technical Manual Section 1, Fastener Tightening Values Table or the toolbox torque tables
(ER-63) for blow-out fitting cap tightening torque. Do not over tighten cap or rupture pressure
can be reduced.
c. All tubing down stream from a force feed pump for a pump circuit rated 5500 psig (380 bar
g
) or
greater (orange, pink and blue disks), that is circuits with any cylinders greater than 3600 psig
MAWP (248 bar
g
), should be 1/4 inch x 0.065 (6.4 x1.7 mm) heavy wall stainless steel high pres-
sure tubing. Rated tubing pressures are calculated from equations in ASME/ANSI B31.3 code
for pressure piping, based on maximum outside diameter and minimum wall thickness. When
grade 316 stainless steel tubing is specified on new compressor sales orders, 1/4 inch x 0.065
(6.4 x 1.7 mm) tubing is provided, regardless of rupture disk or cylinder ratings.
d. Color code changed to pink (3/20/05) was uncoated aluminum.
