Clamp Together Duct
The best solution for dust collection, fine particulate movement, paint booths, industrial ventilation, and some commercial applications. Clamp together duct uses a rolled edge design with an over-center, gasketed clamp to join the pieces together.

How Clamp Together Duct Works
United Team Mechanical’s Clamp Together ductwork die forms rolled lips on the ends of all pipe and fittings. The joint connection is done by a gasketed, over-center clamp that pulls two rolled lips together and envelopes them in the pre-installed gasket. All fittings and straight duct are made with the rolled lip capability. The straight duct is a longitudinal welded seam and fittings are fully welded. Field cut adjustable lengths are made by cutting the standard pipe and sliding a nipple piece over the cut edge, adding a gasket, and clamping the nipple and additional gasket to the cut piece of pipe.
Quality Suppliers
The rolled lip is made on a set of dies that produces high repeatability at a very low tolerance. All of the other components of the clamp together system are our regular high quality welded, round fittings. As with any ductwork, it all begins by using the proper material and adhering to, or in our case, exceeding the industry standard.
HVAC Fabrication and Manufacturing
Clamp Together Options
We offer sizes 3″ – 24″ in every nominal size. Material can either be galvanized or stainless. Standard gauges range from 18-24 with the rolled lip as a continuous extension of the pipe. Heavier gauges are available, in this case a collar is fastened to the pipe, similar to a fitting.

Advantages of Clamp Together Duct
Adjustable Length
After cutting a 5′ length of pipe you are left with a raw edge. You must slide an adjustable sleeve over the cut piece and secure it with an o-ring and clamp. If you need a different length you can undo the clamp and slide the sleeve to your intended length.
Quick and Easy
Installing clamp together duct, when compared to flanged ductwork can provide a large savings in labor. In some cases, savings up to 70% have been reported.
Smooth and Leak-free
The interior of the pipe is smooth and does not have screws, rivets, or other obstructions in the airstream. Unlike spiral pipe, this seam is airtight and excels in the fine particulate collection.
Strength
All ducting and components have been tested to 80″ WG vacuum and positive pressure using the standard gauges. The pipe showed no form of stress or deformation in the testing. The rolled lip provides reinforcement every 5′ or less which outperforms any SMACNA standard.
Reusable
Simple to disconnect and reuse when your shop floor layout changes or machine locations change. The parts you have already purchased can be reused.
Maintenance
Cleaning build ups or clogs in the ducting can be done in minutes. Simply remove the clamp at the buildup, clean the ducting, and reconnect the ducting.
Frequently Asked Questions
How to build a dust collection system?
Begin by sizing a dust collector according to the machinery you are hoping to feed. Typically the require CFM (cubic feet/minute) will be found in the tool manual. Find the maximum airflow by adding up the CFM of all machines that will be running simultaneously.
How to cut dust collection hose?
Rigid pipe requires metal cutting tools, such as: sawzall, double-cuts, metals circular saw. Flex hose requires a sharp knife and a pair of dikes to cut the spiraled support wire. Slice the flex, following the channel all the saw around the pipe, then take the dikes and cut the wire holding the two pieces together. Typically you secure these with worm gear clamps.
How to quiet a dust collector?
Typically the most noise comes from the motor and fan rotation. So there are only really three options:
- Place the dust collector in a separate room that is heavily insulated.
- Enclose the dust collector with sound proofing material
- Purchase some silencers that make a small difference at best.
What is quenching MRI?
Quenching an MRI is typically done when a magnet is being decommissioned, as a life saving procedure, or an emergency precaution. Although rare, quenching an MRI is an event that causes the liquid helium surrounding the electromagnet to boil into gas therefore requiring an exhaust system to the exterior of the building.
How to build a paint booth exhaust system?
We recommend Schubert’s IR catalytic drying system. Not only does it include a filter system that you can just connect to, but it provides very fast dry times. If you are interested in building your own and you need an exhaust system, we typically size a fan and ductwork according to the size of the paint booth.
How to change from spiral or other types of pipe to Clamp Together Duct?
If you are replacing the entire system then we can build a transition from the dust collector or equipment that has a rolled lip on the other end. Similarly, if you have a spiral or flanged duct that needs to transition to a rolled lip, we will build a transition piece. Overall, if you don’t want to mess with the installation, then you don’t have to – we will do it for you.
