BENEFITS
- SINGLE SOURCE FOR ENTIRE
SYSTEM
Give Ricwil® one purchase order and
receive a complete preinsulated HI-GARD system including
carrier pipe, thermal insulation, protective jacketing, prefabricated
fitting and joining materials to meet customer requirements.
- DESIGN FLEXIBILITY
Ricwil's®
aboveground preinsulated piping systems are not a stock item
but rather a combination of available materials that meet each
customer's specific design requirements. Ricwil's®
approach to aboveground piping offers the designewr more latitude
in his selection of carrier pipe, insulation, protective jacket
and pipe joining method. He has the added benefit of being able
to add tracing, as required.
- PREFABRICATED TO ACTUAL JOB REQUIREMENTS
AND DIMENSIONS
A complete system in 6 to 12 meter unitt lengths is delivered
to the job site along with fittings and accessories. Each unit
can be part numbered for easy identification during installation.
Prefabrication reduces material storage and handling requirements
and eliminates waste and damage.
- QUALITY CONTROLLED
All Ricwil® preinsulated HI-GARD
systems must pass a rigid inspection at our plant - not the
customer's. Modern techniques and well trained fabricators are
the customer's assurance of quality. Ricwil®
preinsulated HI-GARD systems arrive at the jobsite with
all insulation protected from elements. Insulation remains dry
and efficient throughout shipping, storage and installation.
- FASTER INSTALLATION
Installation drawings can be supplied detailing all mechanical
components, and electrical if required. No guesswork. Six to
twelve meter of preassembled pipe, insulation and jacketing
is installed at one time leaving only the pipe joint exposed
for testing and field insulating. No longer is it necessary
for an insulator to wait until the pipe fitter is finished to
re-erect scaffolding. Nor is the mess of field applied insulation
there to be cleared up after the insulator is finished.
- REDUCED FIELD COSTS
Ricwil's®
aboveground, preinsulated HI-GARD system improves upon
the old way of field applied insulation and jacketing in new
construction and reduces time and disruption to production in
existing facilities requiring renovation, replacement, or additions.
Preinsulated, prefabricated systems containing one or more pipes
simplify and reduce expensive pipe stanchions.
With all your insulated piping system components purchase at
one time, prefabricated, from one source to meet your particular
design requirements, you achieve the highest product quality
and maximum installation efficiency. Let RICWIL
show you how to obtain the lowest installed cost for your aboveground
HI-GARD system.

LO-TEMP HI-GARD
RICWIL'S
Lo-Temp Hi-Gard piping system is the highest quality, most effifient
and dependable method of providing for obove-ground distribution
of fluids at temperatures up to 130°C.
Lo-Temp Hi-Gard is prefabricated to improve quality
and save labor, the Lo-Temp Hi-Gard piping system is completely
preinsulated to satisfy insulation and jacketing needs for all above-ground
applications, indoors and outside.
Lo-Temp Hi-Gard provides the unparalleled thermal
efficiency of factory-apllied poly-urethane insulation, protected
by any one of a multitude of jacket materials. Metal jackets of
aluminum, galvanized steel, plasticcoated galvanized steel, stainless
steel, and U.V. inhibited plastic jacket of PVC and polyethylene
are all available. Lo-Temp Hi-Gard components are factory assembled
including all necessary fabricated fitting, such as ells, tees,
expansion loops and anchors, so a complete system ready for fast
installation is delivered to the jobsite. Supporting of the Lo-Temp
Hi-Gard system is simplified by the capability of supporting from
the outside of the protective jacket.
MID-TEMP HI-GARD
RICWIL'S
Mid-Temp Hi-Gard piping systemprovides superior BTU saving in addition
to an efficient, high quality, labor-saving method of providing
for the distribution of fluids above-ground at temperatures of 130°C
and above.
A combination of calcium silicate and polyurethane
insulation makes BTU savings possible. These savings are extremely
desirable in electric-traced applications where every BTU saved
lowers electrical equipment material cost and adds to lifelong savings
in power usage. These savings also justify Mid-Temp Hi-Gard purchase
for many district cooling and heating applications, where every
BTU delivered to a customer brings added income to the system owner.
Supporting of pipe system is simplified by capability of supporting
from the outside of the protective capability of supporting from
the outsideof the protective jacket.
Completely prefabricated and preinsulated, the
Mid-Temp Hi-Gard piping system meets the design requirements of
all above-ground installations for services of and above where maximum
BTU savings are desired. Mid-Temp Hi-Gard maintains thermal efficiency
indoors and outside. It consist of a highly thermal-efficient inner
layer of calcium silicate, an outer layer of polyurethane factory-applied
to the rrequired thickness and density, and a protective jacket
of a material best suited to the application. Metal jackets of aluminum,
galvanized steel, plastic coated galvanized steel, stainless steel,
and U.V. inhibited plastic jackets of PVC and polyethylene are all
avialable. These components are efficiently factory assembled, including
all necessary fabricated items such as ells, tees, expansion loops,
anchors, etc., to deliver a complete system to the jobsite.
HI-TEMP HI-GARD
RICWIL'S
Hi-Temp Hi-Gard piping system provides maximum durability in addition
to an efficient, high quality, labor saving method of providing
for the distribution of fluids above ground at temperatures above
150°C.
The combination of RICWILs exclusive nonflammable
insulation locking agent with calcium silicate makes maximum system
economy possible.
Hi-Temp Hi-Gard is a specially formulated, high-strength
inorganic locking agent that exhibits virtually no temperature limitations
when used in a RICWIL piping system.
The inorganic locking agent's high-compression
strength, plus the combination of insulation materials that allows
RICWIL to apply the minimum thickness of insulation required to
maintain desired temperatures, results in a rugged, durable system.
A system that allows maximum bearing loads with maximum support
spans. These design savings are added to the economy of Hi-Temp
Hi-Gard minimum insulation thickness.
Completely preinsulated to handle all temperatures,
the prefabricated piping system is particularly suited for indoor
and outside applications. Supporting the Hi-Temp Hi-Gard system
is simplified by capability of supporting from the outside of the
protective jacket.
Hi-Temp Hi-Gard consists of inner layer of calcium
silicate insulation, factory applied to the required thickness,
sealed with a polyethylene shield, covered by an outer layer of
RICWILs exclusive inorganic locking agent for strength, and protected
by any one of a multitude of metal jacket materials.
Hi-Temp Hi-Gard's nonflammable barrier permits
its use in all commercial and industrial environments.
Metal jackets of spirally locked seam aluminum,
galvanized steel. Plasticcoated galvanized steel and stainless steel
are available. These components are factory-assembled including
all necessary fittings, such as eils, tees, expansion loops, and
anchors, so a complete system ready for fast installation is delivered
to your job site.
