Trac-Loc™ Vertical Lock-Seam Tank Insulation

Trac-Loc is a standing lock-seam insulation panel system that delivers structurally superior, maintenance free, and lower cost insulation than conventional tank insulation methods.

APPLICATIONS

Trac-Loc is ideal for large, flat-bottomed tanks used for storage of materials that are sensitive to temperature fluctuations and require a covering of insulation and jacketing to reduce heat loss or gain.

DESCRIPTION

The Trac-Loc Vertical Lock-Seam Tank Insulation System is unique due to its design, panel construction, and installation techniques.

DESIGN

The Trac-Loc advanced interlock panel system consists of prefabricated panels of insulation and jacketing material. These panels, fabricated to the height of the storage tank, include flanges that are mechanically seamed to an adjacent panel. This mechanical seam creates a homogeneous jacket that not only secures the panels to the storage tank, but also reduces moisture ingress, damage due to wind, and inherent expansion and contraction of the stor-age tank.

PANEL CONSTRUCTION

Panels are fabricated by laminating insulation material to a preformed jacket. Insulation can be made up of one or more insulating materials. Jacket materials conform to industry standards. The following tables contain some of the typical insulation and jacketing materials used for panel construction.

Interlock™ Clamp-on Pipe Shoe

The Interlock clamp-on pipe shoe is a patented pipe support design that eliminates field-welding requirements for pipe supports.

APPLICATIONS

Pipes that can be installed on supports include bare pipe, painted pipe, insulated pipe, and heat-traced pipe. Using the clamp-on pipe shoe can allow you to:

• Minimize or eliminate wear on the pipe caused by normal movement of a pipeline. This movement can be attributed to many things, including thermal expansion of the pipe due to process temperature changes or changes in ambient temperature.

• Provide a means for guiding the pipe so that multiple lines within a rack do not rub against one another during normal movement.

• Allow spacing between the pipe support and the pipe itself to facilitate the installation of pipe insulation.

The Interlock clamp-on pipe shoe is not intended for anchoring or vertical support requirements.

DESCRIPTION

The Interlock shoe includes a base with either two or three (depending on the application) support tongs welded to it. These support tongs have a lever gap stamped in their base, through which a mating tong is inserted. When the mating tong is bolted to the support tong the pipe ends of the tong are drawn together, gripping the pipe.

The entire assembly is galvanized (6 mil thick) for corrosion protection.

The Interlock shoe can be used on nominal pipe sizes ranging from 1-in (25.4 mm) through 8-in (203 mm), and is available in heights of 3-in (76 mm), 4-in (102 mm) or 6-in (152 mm) to accommodate varying thicknesses of pipe insulation.

The Interlock shoe is made out of A-36 carbon steel, but is also available in other materials of construction for special applications. The standard (A-36) Interlock shoe can be used in ser-vices from –20° F (–29°C) to 400° F (204°C).

When the Interlock shoe is used on stainless steel pipe an optional isolation insert is avail-able to isolate the dissimilar metals, in compliance with most pipe support specifications.

ADVANTAGES

• Reduced cross sectional area (as compared to conventional clamp on shoes).– Reduces space requirements in the pipe rack, minimizing rack congestion.

• Reduced heat loss at the pipe support.– Minimizes the need to serpentine or loop heat-tracing cable or tubing, eliminating as

much as 15% of the heat-tracing requirements on a typical application.

• Eliminates field welding for supports.– Achieves a higher level of quality.– Eliminates rework because the shoe was not located correctly.– Eliminates the need for scaffolding or lift equipment.– Eliminates the need to paint pipe support field welds.– Eliminates the need for fire watch or full weld enclosures.– Eliminates the need for hot work permits.– Eliminates stress corrosion of pipe at welds.

• Easy to install.

• Doesn’t retain moisture between the support and the pipe.– Eliminates corrosion by not allowing moisture (or other corrosive media) to collect

between the support and the pipe.

• Less costly (as compared to welded-on supports).– The total installed cost of an Interlock shoe is significantly less then the total installed

cost of a welded-on shoe.

PRODUCT SELECTION AND CATALOG NUMBER ASSEMBLY

Product Selection

• Determine pipe size– Available in sizes 1-in (25.4 mm) through 8-in (203 mm)

• Determine height requirement – considerations include:– Pipe rack spacing/density– Insulation thickness– Standard heights include 3-in (76 mm), 4-in (102 mm), and 6-in (152 mm)

• Determine length– Length is determined by analysis of piping conditions and is designed to accommo-

date expected movement based on expansion and contraction of piping system.

Prefabricated EHT Buildings

Tracer prefabricated EHT buildings are custom designed and built to allow for centralization and protection of field-based control and monitoring systems used in heat-tracing applications.

APPLICATIONS

Systems requiring a large number of heat-tracing circuits located within a limited amount of acreage may benefit from the use of a prefabricated building designed exclusively for heat-tracing requirements. The prefabricated building allows for the installation and utilization of the control and monitoring system, while eliminating any additional costs for individual field unit protection from the outdoor environment.

DESCRIPTION

Prefabricated EHT buildings are custom-built to meet the particular combination of control points and power distribution requirements. The buildings are assembled off-site in a con-trolled environment and are delivered to the site completely assembled, reducing scheduling impact. These EHT buildings are specifically designed to minimize impact on real estate and to be located within the unit close to the circuits that will be powered. To further centralize the system components, the EHT building can serve as an ideal location for installation of power distribution equipment, heat-trace transformers, as well as a work area containing computer and supervisory software dedicated to the heat-tracing system. Another benefit created by centralization of components includes a reduction of power distribution equipment and con-trol wiring, as locating power distribution and control and monitoring devices in the more traditional MCC buildings often requires excessive conduit and wiring.

For applications requiring fewer circuits, Tyco Thermal Controls offers a complete line of Control and Monitoring panels designed for field mounting.
