Ravenna, OH
Catalog Number 4200-M-2 General Technical Information
Testing Specifcations for Metal
Tubing:
All metal tubes used in the manufacture of Multitube
are subject to stringent magnetic analysis using a
special eddy current tester. Each tube, after eddy
current analysis, is pressure tested at not less than
250 psi for 15 minutes without any sign of leakage.
When Multitube assemblies have completed the
manufacturing process, each tube is again tested with
dry N2 at 250 psi for 5 minutes prior to shipment.
Testing Specifcations for Plastic
Tubing:
All plastic used in the manufacture of Multitube are
subject to rigorous Q.A. inspection and testing prior
to shipment. Each tube is pressure tested at not
less than 150 psi for 15 minutes without any sign of
leakage.
When Multitube assemblies have completed the
manufacturing process, each tube is again tested with
dry N2 at 125 psi for 5 minutes prior to shipment.
Notes:
Copper and Stainless Tube
§Pressure data for temperatures above 200°F are
included for reference only.
Plastic coated tubing should not be used at
temperatures exceeding approximately 80°C due to
the PVC (or PE) jacket employed.
Copper - Armored Tubing
§Pressure data for temperatures above 200°F
are included primarily for where the tubing must
withstand higher ambient temperatures. The
assembly should not be used at temperatures
exceeding approximately 80°C (176°F) due to the
PVC tapes and jackets employed. Consult the
Division if higher temperatures will be encountered.
Copper - Jacketed Tubing
§Pressure data for temperatures above 200°F
are included primarily for where single runs must
withstand higher ambient temperatures than the
Multitube bundle. The Multitube bundle should not be
used at temperatures exceeding approximately 105°C
due to the PVC jacket employed. Consult the Division
if higher temperatures will be encountered.
Stainless Steel - Jacketed Tubing
§Pressure data for temperatures above 200°F
are included primarily for where single runs must
withstand higher ambient temperatures than the
Multitube bundle. The Multitube bundle should not be
used at temperatures exceeding approximately 105°C
due to the PVC jacket employed. Consult the Division
if higher temperatures will be encountered.
