Clamp Together Duct – Have You Offered It ?

The Clamp Together Duct System

Until you use it, it’s a bit hard to comprehend – Clamp Together Duct is FAST, VERSATILE AND EXACTLY WHAT YOU NEED!

Never use the Clamp Together Duct System? Here’s some frequently asked qustions to get you considering it as an option for your next dust collection application.

 

  • What sizes and materials does it come in? US Duct’s clamp together duct system is available in 3”-24” diameters, in light or heavier gauge (up to 10) and in SS, galvanized steel and carbon steel. The clamp together system is built with standard 5’ sections of pipe, reinforced at every connection with the stainless steel clamp. Elbows are available in all/any radius. Branches and fittings are made to requirement and desired configurations.
    How ‘air tight’ is it? The clamp gasket, in rubber or optional synthetics, creates a tight seal. Optional peel and stick gaskets applied to the face of the rolled lip make for an even tighter connection. View gasket installation video.
  • What exactly is Clamp Together Duct? Clamp Together Duct is an industrial ducting system that uses an over-center clamp to join the rolled lipped ends formed onto the end of ALL duct components- pipe, elbow, branches, all fittings and specially fabricated parts. Further the system is fully adjustable, utilizing the fact that a cut piece of pipe will slide into either the 11” adjustable sleeve or the end of any fitting. The pipe is then clamped to the sleeve or the fitting by using a rubber O-ring that secures the pipe to the fitting or sleeve as the clamp connects the two.
  • Can clamp together be used in Oil Mist applications? Absolutely- When a job is specified as oil mist, epoxy caulk is used in lieu of the standard sealants. HOWEVER there are some additional aspects to be considered during installation as well. The duct must be hung straight, without any lateral stress caused by ‘pulling’ the duct into alignment with a pickup point. Pulling the duct opens up the clamp and will prevent the gasket in the clamp from sealing properly. Additionally adjustable sleeve/ pipe assemblies need to be installed with consideration to the drainage of the liquid. And lastly, the standard gasket is buna-n rubber and may be affected by certain phosphorus or Sulfur based effluents. Such may require a goretex or viton gaskets.
  • I have heard Clamp Together Duct is fast, but expensive. Is that true? Straight pieces of spiral duct are cheaper than straight pieces of clamp together duct but are normally of thinner gauge. Longer length spiral can install with fewer connectors but freight cost usually eliminates that advantage. Fittings (elbows, branches, etc) are about the same when compared in conquerable gauges. The competitive advantage for Clamp Together Duct is that it so easy to install that anyone of any skill level can install the duct in approximately 50-70% LESS time than traditional sheet metal mechanic can install spiral or flanged duct. This makes the Clamp Together Duct very cost effective. Additional savings are derived by minimizing waste associated with common cutting and fitting mistakes associated with duct that requires precision cuts. The simple clamp connectors also allow for disassembly, cleaning, reconfiguration and re-installation- making clamp together duct totally reusable over and over. When you compare the total cost of your system – materials, labor, waste, ongoing maintenance, etc. – Clamp Together Duct is very competitive as an alternative to spiral duct.
