MI - Mineral Insulated Electric Trace Tubing —
High Temperature Maintenance
General
Parker MI-Mineral Insulated order-to-length
series resistance MI Trace electric trace tubing
consists of a single process tube electrically traced
with a series resistance mineral insulated heating
cable, a heat transfer foil wrap, a nonhygroscopic
glass fber insulation, and a black, 105° C rated,
fame-resistant PVC (FR PVC) jacket.
Parker Mineral Insulated MI Trace is designed for
various temperature ranges including:
Freeze protection and viscosity maintenance of 40°F
(4.4° C) to 80° F (26.7° C) at ambient temperatures
down to -60°F (-51.1° C); and Process temperature
maintenance of 120° F (48.9° C) to 170° F (76.7° C)
at -60° F (-51.1°C) and 260° F (126.7° C) to 310° F
(154.4° C) at 80° F (26.7° C).
Standard product has a Maximum Temperature
Rating (MTR*) of 400° F (204.4° C). Higher
temperature rated designs are available. Consult
Division for details.
*Maximum Temperature Rating is the maximum
allowable temperature of the tracing fuid.
Temperatures in excess of this may damage the
product or alter its performance.
Applications
Analyzer, impulse and instrument lines; small
diameter process lines; stack gas sampling lines; and
utility lines.
Tubing
Type 122 DHP Seamless Copper and 316/316L
Welded and Seamless Stainless Steel are standard.
Additional materials and wall thicknesses are
available upon request. For Material
Specifcations of metal tubing, see Technical Data
section of the catalog. Consult Division for details.
Heat Transfer Foil
An aluminum heat transfer foil for even heat
distribution for precise temperature control.
Insulation
Patented (U.S. Pat. No. 4,285,369) air-spaced,
cross wrapped applied non-hygroscopic fberglass
thermal insulation or high temperature composite dual
insulation system for minimum heat loss.
Jacket
The tough, black, 105° C rated, fame-resistant PVC
(FR PVC) jacket protects the tubing against corrosive
atmospheres, water, oils, acids, alkalies and most
chemicals. Additional jacket
materials are available upon request. For Material
Specifcations of jackets, see Technical Data section
of the catalog. Consult Division for additional details.
Testing
Each tube in every length of Parker Mineral Insulated
trace is pressure tested prior to shipment to assure
the instrument engineer a high quality, reliable,
trouble-free product. For Testing Specifcations, see
Technical Data section of
the catalog.
Maintain Temperatures up to 900°F (482°C) and withstand Maximum
Internal Exposure 1000°F (538°C)
