The Brilliant Belly Saw

Often time contractors find themselves stuck in tight situations where large diameter pipe needs to be cut, but the conditions are not optimal for the use of industry standard pipe cutters or saws.  Cutting pipe in cramped conditions can be a real nightmare.  Couple that with wet conditions and you could be setting yourself up for disaster.  That’s where the U.S.SAWS Belly Saw comes in and makes life a whole lot easier for those wet cuts in narrow spaces.

Applications of a Belly Saw

The belly saws supplied by U.S.SAWS are ideal for pipes ranging from 8 inches to 24 inches, 24 inches to 48 inches, and 48 inches to 72 inches in diameter.  Contractors and utility workers use these innovative saws for cutting subgrade pipes in tight conditions as it only requires 7 inches of clearance to work, eliminating the need to clear out excessive amounts of dirt to create the cut, which then saves significant time and effort.  If a pipe has burst and needs to be cut and repaired, having to clear out a wide area of sludge under and around the pipe increases the amount material lost from leaking out of the pipe and requires more effort and manpower to clear out, thereby increasing the total cost of the job.  The belly saw provides the workers the ability to make the cut quicker by reducing the amount of space needed for saw clearance and under safer conditions.

U.S.SAWS manufactures and sells belly saws that are pneumatically or hydraulically powered.  These powerful saws with their Tiger Tooth blades make cutting PVC, HDPE, ductile iron and cast iron pipes a breeze, creating precision cuts every time.

Benefits of a Belly Saw:  Increased Safety

Wet and tight are never conditions that meld together to create a safe pipe cutting scenario.  U.S.SAWS has solved that problem through their belly saw. U.S.SAWS is always looking for ways to develop tools that protect workers.  Their belly saws do not disappoint in this regard.  These saws are water saws in that they are ideally used in wet conditions.  As safety is paramount in the design of these saws, U.S.SAWS first ensures that the saw is equipped with its top of the line Tiger Tooth saw blade.  Sharp blades make lessen cutting time, which then reduces the amount of time spent using the saw.  For cutting pipe ranging from 8 to 24 inches, the belly saw comes equipped with an 8 inch blade.  Pipes with diameters of 24 to 48 inches and 48 to 72 inches would use a belly saw equipped with a 12 inch Tiger Tooth blade.  The next safety feature of the belly saw is its clamshell design.  This shell design surrounds the saw and protects the workers from those sharp blades before, during and after the cut.  Another safety feature for these saws is how they are powered.  By using air or hydraulic power in small, cramped spaces, emissions are non-existent, and workers are not forced to breath in harmful fumes.  Finally, the vital safety feature of this water saw is the strap used to affix the saw to the pipe.  By strapping the saw to the pipe itself, the saw can be drawn around the pipe for a fast and accurate cut.  Further, U.S.SAWS supplies a “water kit” for use with steel pipes to suppress sparks.

Save Time with U.S.SAWS Belly Saws

Not only has U.S.SAWS taken safety into account for the development of their belly saws, they also want to ensure the saw is an efficient tool.  The entire purpose of the “tool” is to make a regular job easier.  U.S.SAWS understands that time is money, not only for the workers, but also for the municipalities or businesses employing the workers or supplying the materials flowing through the various pipes.  The 7 inch clearance space required to cut fully around a large diameter pipe is nothing compared to other tools used for similar jobs.  Less prep work means less time and money spent.  By requiring such minimal clearance for such a large job, the workers’ time normally spent on clearing space, can be used attaching the saw and focusing on creating an accurate cut.  Further, the accuracy provided by using the strap and wheel system requires less effort by the workers during back breaking work, and also enables the workers to make easy accurate cuts, reducing the need to fix a poor cut.

U.S.SAWS is an innovator in the tool industry.  In balancing safety and efficiency, U.S.SAWS has developed yet another saw that will revolutionize the world of pipe cutting.  Contact U.S.SAWS today to find the right belly saw for your business

The One Man Polyurea Pump

With the popularity of concrete in modern construction practices, every concrete worker is familiar with the control joint, whether for walls or for flooring.  Control joints are a necessary part of concrete work.  As concrete ages over time, it shrinks.  That shrinkage leads to cracking within the slab of concrete.  While the cracks are inevitable, they are manageable.  If not managed with properly placed control joints, the cracks are unmanageable and difficult to maintain.  This is where control joints come in to save the day.  Control joints act as a planned crack to ensure the cracking is straight and manageable. The control joints work by filling the joint space next to a specific slab of concrete with the right filler that will expand as the concrete shrinks, allowing the concrete to maintain its form and cover the same amount of space, without unmanageable cracking.  These joints are a necessary part of concrete work and must be planned for and spaced out accordingly.

There are two industry-standard types of joint fillers:  epoxy control joint fillers and polyuria control joint fillers.  Semi-rigid epoxy fillers are easy to use, have a flowable pour, and may be applied with a bulk gun or a dual component pump.  However, polyuria control joint fillers appear to be the better option of these two fillers.  Polyruea fillers have the same advantages as the epoxy filler, but also are fast-setting, which allows for a quick shave making them perfect for caulking or repairing existing cracks.  Another plus of the polyuria filler is that it can be made in a multitude of colors.

How Does a One Man Polyurea Pump Work?

Now that we understand the benefit of the polyurea filler for our concrete control joints, we need to understand more about the application of the polyurea filler.  Just like the epoxy filler, polyuria filler can be applied manually or with a dual component pump.  Dual component pumps are necessary for the chemical reaction to take place to form the polyuria.  Specifically, the chemical reaction creates the polyuria through the mixture of a resin component and an isocyanate component (often a soft block prepolymer).

The One Man Polyurea Pump allows a single person to manage the pump with both of their hands managing different aspects of the filling operation.  One hand controls the pump’s position.  The other hand dispenses the joint filler with the other.  The user must first premix any necessary polymers and then ensure the correct items are placed in the correct poly tanks.  Cross-contamination is a real issue and needs to be avoided.  Once the correct materials are placed in their respective poly tank, the user should conduct a test spray through the manifold to ensure the stream is even and equal. If that test is even and equal, then the static mixing tip should be added to the manifold .  Once the static mixing tip is added, applying a test strip of polyuria to a piece of cardboard will allow the user to ensure the cure time is also proper. As the test cures, discard the static mixing tip and pump grease into the fittings of the manifold to prevent any cross-contamination.   After the test cure is deemed correct, the mixing tip should be replaced with a new one and the joint filler may then be applied.  It is essential to maintain the cleanliness of the pump to ensure it works properly for you during the next use.

Why is it Better Than a Traditional Pump?

The benefit of the One Man Polyurea Pump comes down to efficiency.  This pump allows one person to handle the task of joint filling while other members of the work crew focus on other facets of installing or repairing concrete.  Traditional pumps would require multiple people to operate.  One person would handle the application, another person would manage the pump position, and potentially a third person would manage the levels in the poly tanks.  Not only does the work crew become more efficient, but it is also cost-effective for the business owner as the cost of labor for the business decreases by using a one-man pump as opposed to the traditional pump.

Features of U.S.SAWS One Man Pump

U.S.SAWS features an industry-leading One Man Polyurea Pump with its SX20550 model.  This pump is a prime example of why the one man polyuria pumps are essential to a concrete working crew as it is perfect for single person operation.  The pump is equipped with a T handle that allows the user to easily guide the pump during the application process by knowing precisely where the pump should be to avoid wet floor joints.  When moving the pump to a new position, the attached waste bucket provides a place for the mixing tip to drip instead of on the floor.  There is also storage for a battery or generator as needed.  The poly tanks hold a volume of 6.5 gallons, and are semi-transparent to allow the operator to monitor fluid levels.  The SX20550 also comes with an enclosed box that is perfect for tool storage.  For the operator that requires something different from the standard 1:1 component ratio, U.S.SAWS does offer a 2:1 component ratio if needed.
