The Strong Seam® paneling insulation system reduces maintenance and installation costs, thanks to its durable design and high-quality materials. It is engineered for long-term performance with minimal upkeep, providing cost savings across the lifespan of the tank.
Straight Line’s expertise ensures an efficient and reliable solution, offering seamless installation that doesn’t require scaffolding or hot work permits. This results in improved safetyandreduceddowntime.
MACHINE FORMED STANDING SEAM CONTOUR
The Strong Seam® system features a robust, machine-formed standing seam that joins adjacent panels, extending the full height of the tank. This secure seam incorporates retention clips that fasten the panels to steel cables, which are tightly wrapped around the tank’s perimeter. The double-locking seam ensures longterm stability and ease of installation, creating a durable and effective insulation solution for the tank.
Our tank design features the Strong Seam® insulation system, which comprises vertical panels secured by cables around the tank wall. The Strong Seam® panels are attached to anchor cables with “T” clip fasteners. These “T” Clips extend outward at the seams, which are machine rolled with the “T” Clips to lock the panels together and secure them to the anchor cables, eliminating external banding.
SULPHUR, HOT OIL OR ASPHALT TANKS
When the tank operating temperature exceeds 275˚F, the tank will expand or retract during the course of the tank start up or shut down, causing the insulation system to crack which will require a replacement at your own expense. In cases like this, we highly recommend an expansion joint for the roof to help deal with this issue. An expansion joint of the tank insulation serves a purpose to absorb the lineal motion caused by the heat expansion. We recommend a two layer application for side-walls and roofs.
ENGINEERED STEAM TRACING SOLUTIONS
Heat tracing is the practice of heating piping to maintain a constant material temperature and compensate for heat loss. For steam tracing, the heat is generated using excess steam from other processes.
TYPES OF STEAM APPLICATIONS
•Conventional Tracing
•Single & Double Insulated Tube
•Bare Tube with HTC
•Snap Trace
•Contro Trace
•Hot Oil
STEAM TRACING
Steam Tracing is described as the attachment of a tube (Copper or Stainless) containing saturated steam, also known as the “tracer”, parallel to the process fluid pipe. The two pipes are then insulated together with the appropriate insulation and jacketing. Although Steam Tracing is more intensive compared to electrical heat tracing, there are fewer risks associated with it. The temperature of the tracer cannot surpass the maximum saturation temperature of the steam, as it operates at specific steam pressures.
Straight Line offers manifold installations and designs, including full packages of steel Forge Manifolds. The MSC forged steel manifolds centralize steam distribution and condensate collection for up to 12 sources. These manifolds feature various connections, making them ideal for tracing applications. Their compact design allows easy access for trap maintenance and monitoring, while the mounting arrangement ensures quick installation. The condensate collection manifold includes an internal siphon pipe to promote even temperature distribution and ensure single-phase discharge of condensate. Straight Line's quality systems provide a reliable and easy-tooperate solution that is plant-friendly and meets everyday process demands.
At SLIS we know that at the heart of every trace heating system is thermal insulation and our experience gives us the advantage. Our specialists have been installing and maintaining heat tracing systems for over 17 years. We offer turn-key solutions, with control & monitoring systems. We manufacture Forged Steam and Condensate Manifolds along with install to ensure quality. We are a Certified Contractor for allControTrace Systems, design and installation. So, whether you need Electrical Heat Trace, Steam Trace or ControTrace for your next project or need confidence in your plant’s ability to operate efficiently through the winter, contact: SLIS Proving Experience in the ART OF RELIABLE HEAT TRACING.
HEATING CABLES
POWER BOXES
AMBIENT SENSOR
The demands placed on heat tracing systems vary based on the design parameters specific to each application. To meet these needs, Straight Line Industrial Services, Inc. uses Thermon® manufacturing as its supplier who has the widest variety of electric heating cables and control systems in the world.
ELECTRIC TRACING
Similar to steam tracing, but instead a heating cable that is constantly transmitting wattage is attached to the process fluid pipe. This system is monitored by a Microprocessor-Based Control Unit which permits on-off heat tracing control with numerous capabilities such as readings of the heating and temperature of cables. The heat cable and the pipe are insulated together with the specified insulation and jacketing. Electrical heat tracing is less work labor than steam tracing.
