NON-METALLIC EXPANSION JOINTS

Flextech non-metallic expansion joints are engineered to solve thermal growth and vibration problems in air and flue gas systems. We offer numerous single and multi-layered type materials for a range of temperatures and chemical environments.

 

  • E Series Elastomers (Viton, EPDM, Butyl, Neoprene, Silicone)
  • FC Series Flouroplastic (Teflon based) PTFE impregnated fiberglass: high temperatures, wet/dry service.
  • FL Series Flouroplastic (100% chemically inert) for medium temperatures and severe chemical conditions
  • M Series Multi-layered for hot air and flue gas applications operating up to 2000°F.

 

Our non-metallic expansion joint assemblies consist of either belt or integral flange styles. We offer a variety of frame designs. We can custom design units to fit your needs. Round, square, rectangular and cylindrical joints available in an unlimited size range.

 

Here various types and styles we can offer:

    SUPER THERM - Defeating the theory of (R)

    with true heat reflection, not absorption

In conventional insulation, the measurement of resistance is based upon the transference of heat through an insulation material. This measurement is known as (R). Insulation materials that use this guide of resistance are a means to temper heat , but also require thickness. The thicker the material, the slower the time will be to absorb and eventually transfer the heat from the external source into the insulated environment. These typical roof materials such as EPDM, TPO, Modified Bitumen, or any Cool Roof Technology materials allow a 100% loading of surface heat facing the heat source.

Super Therm® does not absorb heat and, therefore, does not require thickness—effectively eliminating a measurement of (R) value. Super Therm® is a blend of ceramic compounds that, when applied to a surface, will reflect heat away from protected areas. Super Therm® only allows a 5% heat load of the surface facing the heat source.

Dave!  Don't touch that, it is HOT!  No, it is NOT.

 

 

Yes, that is our fearless coatings products director, Dave Murat, with his hands on a 400 degree Fahrenheit static pipe display at the 2011 Iron and Steel Show.  Surface temperature was about 80 degrees with 1/4" product thickness…try that with insulation packages, I dare you. 

 

The product is called HPC® coating is designed specifically to block conductive heat transfer in industrial applications (i.e. baghouse walls, pipes, tanks, fans, valves, and buildings) up to 700oF (371oC).  Here a few product highlights:

 

·  HPC® is a water borne ceramic coating and extremely lightweight in appearance.

·  HPC® uses a special acrylic resin blend with specific ceramic compounds added to provide a non-conductive block against heat transfer.

·  HPC® coating is a "green" non-flammable, non-toxic formula for high heat surface applications.

·  HPC® can be applied to metal, concrete, masonry and wood surfaces.

 

HPC® coating replaces traditional jacketed insulation as a high performance insulating system.

 

Energy costs are staggering and as managers you struggle everyday with finding ways to keep their plant process heat.  We have a saying here in Texas, "you can lead a horse to water but you can't make him drink"…that big energy horse in your plant is thirsty and here is a tall cool glass of water.  No, Dave you are not the tall cool glass of water. 

 

So why choose ePTFE membrane over conventional filter medias?

Membrane filter bags has been a proven performer in both reverse air and pulse jet baghouses for numerous years over various market segments. Membrane has also proven to be a cost-effective choice for dust particle collection and emission control. Due to the ePTFE membrane’s ability to integrate to the base filter media, you can achieve 99.99% filtration efficiency. Its smooth surface provides just cake and the media’s lack of loose fiber ends provides a hydro and oleophobic characteristic to provide a secondary cake release.

  1. Reduced Emissions (PM 10, PM 2.5 and Sub-Micron PM)
  2.  
    Lower Pressure Drop
  3. Longer Effective Bag Life
  4. Good Recovery from Upset Conditions
  5. Full Collection Efficiency At Start-Up
  6. Reduced Cleaning Air Consumption
  7. Energy Savings

ROBINSON FANS - Guarantees Lab Tested Performance  

Robinson’s BC0928 fan design is tested in accordance with the same AMCA approved procedures as our other complete new designs, so that Robinson guarantees the laboratory tested performance results.  However, retrofit situations present some peculiarities such as system effects due to the duct design or buildup within the system as a result of extended use that changes the specifications of the customer’s system. In a retrofit situation, the actual baseline performance often is different than the fan’s original design point. The physical condition of the casing and/or accessories can affect performance of the fan. Thus, Robinson guarantees its laboratory tested performance results and at the same time seeks to acknowledge the difference presented by each application.

 

Robinson’s BC0928 fan design offers energy efficiency upgrades with the value added:  Service, technical expertise, right tools, AMCA–accredited laboratory, and credibility.

 

The goal: Rotor retrofit >80% Eff.

·        Replace rotor and inlet piece, minimal casing modification

·        Wear/Build-up resistance at least as good as the FRD

·        Credible predicted performance

·        Optimized structural design

·        Use existing manufacturing methods

DUCT BALLOONS - Inflatable Platforms

Duct Balloons are specially designed inflatable duct balloons can be used as temporary platforms in confined spaces. Company safety rules may dictate that any employee working in a confined space with inwardly converging walls must be able to exit the duct work without assistance, otherwise a confined space rescue team may need to be present. We offer specially designed duct balloons made to your duct work dimensions and shape that can be used as an inflatable platform where scaffolding can be labor intensive to install and result in increase outage times. Applications are in boilers, hoppers, pressure vessels, storage  tanks, and many others.

 

Duct Balloon is an inflatable barrier that can be inserted through existing access doors in duct work and will perform much better than wood frame and plastic barriers. They are constructed out of a durable wear resistant fabric rated up to *500°F (260ºC) and can be reused outage after outage. They are designed so that they will pass through most existing man ways for ease of installation and removal.  Using the supplied 120V or       220V blower system, they install quickly and become fully inflated in five minutes or less. They can be quickly removed from the duct work by turning off the blower and then open the large deflation zipper. Applications are in SCR’s, FGD systems, gas turbines, HRSG exhaust stacks, primary air ducts in coal pulverizers and many others.
