TANK PANELING SYSTEM

The Strong Seam® Panel Insulation system consists of a composite panel created from laminating a metallic outer skin to thermal insulation. Adjacent panels are held together via a machineformed weatherproof standing seam, the heart of the Strong Seam® system that extends the entire height of the tank. Captured within the double-locking seam are retaining clips that attach the panels to steel cables which are securely wrapped around the circumference of the tank. Specially formed insulation panels can also be installed on tank roofs. With this type of insulation system, there is no need for scaffolding.

SCAFFOLD ELIMINATION Saves you Money!

If the tanks location is susceptible to ground water or if the tank contents could leak, the bottom of each insulation panel can be equipped with Cellular glass insulation.

Strong Seam® panels can be trimmed and sealed to fit around tank protrusions such as stairs, ladder brackets, nozzles and Man ways. SLIS, Inc. can also manufacture manways removable insulation Straight WRAP™ covers.

Strong Seam® easy installation

SAFETY & QUALITY OUR FIRST PRIORITY Every Strong Seam® installation is approached with the dedication to safety and quality instilled by SLI management, while maintaining scheduling and cost necessities that are critical in today’s marketplace.

OUR EMR AS OF February 2025 is 0.76

Manways, Nozzles, and other protrusion are closely fitted and sealed.

Skilled, trained, and certified SLIS employees can install a Strong Seam System without the need for scaffolding, welding or hot permits.

For most applications, a climbing basket (work cage) suspended from tank’s center nozzle or painters lug, permits the seaming machine and our personnel to travel the height of the tank without the need of scaffolding.

Quality work at its best!

TANK INSULATION SYSTEM

A Strong Seam® tank insulation system reduces the installed cost of a tank insulation package while lowering long-term maintenance requirements. These savings are due primarily to the design experience and commitment to quality construction by Straight Line Industrial Services Inc. Machine Formed Standing Seam Contour: The heart of a Strong Seam® system is the machineformed standing seam that bonds adjacent panels together. This weatherproof seam extends the entire height of the tank and is also used on the panels that make up the insulated tank roof. Captured within this doublelocking seam are retaining clips that attach the panels to steel cables which are securely wrapped around the circumference of the tank.

TANK ROOF INSULATION SYSTEM

SLIS offers different Roof Systems layout depending on the tanks sizes. We can also make the roof panels in different materials such as aluminum or Galvalume per request.

Profiles: Flat, Cone, Elliptical, Dome, Sphere or Chevron Systems.

Steel Cables, temporarily held in place with stick pins or Finger clamp bands, are wrapped around the perimeter of the tank and secured with turnbuckles.

Optional foam glass thermal insulation can be installed at the tank’s base when ground water wicking or tank content leakage is possible.

Double Layer Insulation System

Many of our customers are increasingly concerned about using less energy and managing their CO2 emissions when it comes to Asphalt or Sulphur tanks. Many of our customers ask us about this type of concerns and what can we do to help them reduce it or resolve it.

In order to have a cost-effective way of maintaining a constant heating temperature in these tanks, the use of sufficient and proper amount of insulation is essential and necessary for the exterior of the tank. Whether it is mineral wool or fiberglass, the tank insulation materials may get wet and cause moisture to build up between the insulation and the tank.

Wet insulation is like a saturated sponge and can jeopardize the effectiveness of the insulation. In cases like that, we also offer double layer insulation systems that maximize thermal conservation.

One of the best designs in its class to more efficiently reduce heat loss and allow for future expansion in confined spaces.

Besides those great assets, they also offer long-term reliable performance, easy installation, and maintenance free.

We offer Heat Tracing Services Electrical or Steam

Sulphur, Hot Oil or Asphalt Tanks: When the tank operating temperature exceeds 275 Degree F, these tanks will expand or retract during the course of tank start up or shut down, we highly recommend an expansion joint for the roof, the reason for this is as follows: When a pipe or tank heats up, they tend to expand thus comes a need for an expansion joint. Without one, the insulation system stands the chance of cracking causing big problems and costing you more money. Many materials expand with the increase of heat, especially piping and tanks. To help deal with this issue, an expansion joint acts as a way for the tank to absorb the linear motion caused by the expansion. It is also recommended to do a 2 layer application for sidewalls
