Building a Flow Loop with Clear Rigid Plastic Tubing and NPT Threads We were recently contacted by a Ph.D. student working on a multi-phase flow problem. The application called for a clear rigid tubing flow loop that would maintain a circular shape under pressure with...
Specialty Bends
Frequently we are asked to make UBends (180°) bends. In a UBend, the offset is twice the radius, and keeping the offset is the trick. In thermoplastics bends the tubing tends to pull in or out (memory) and work as a thermometer with radiant heat. Our process minimizes...
Quite often our customers ask us for bends without tangents. Mostly it is for aesthetic reasons, but often enough it is for a particular process need. Such bends bring a special challenge. Thermoplastics' bends, due to the requirement of secondary heating, have...
Offsets: Busada was one of the first plastics tubing and pipe manufactures to offer customers long radius sweeps, and we have done it for over 65 years. Before we had our advanced heaters, we would use hot oil, salt, glycol, vermiculite and other ways to heat the...
We made these P traps for HVAC equipment. We considered smoke gray, with butyrate or PETG tubing. In the end, we went with a .5" OD x .060w, clear transparent butyrate tube. Got to admit, this was a challenge to get this tiny multi-bend right. The plastics tubing will...
We often fit bends to pneumatic (or other) systems from a distance. We ask the customers to send us as much information as they can provide. From that, we do our best to calculate OD, radius, and angle of the bend. Here is another example from last week. As you can...
A water treatment company needed a system to display its product in its showroom and for trade shows. The system required 4" Schedule 40 Pipe that would be bent, coupled, threaded, and coupled with tees and wyes. It was challenging in a number of ways. We had to cram...
We have a bunch of blogs on tight-radius bends, and of U bends. Here is one that we made for one of our puck-conveyance customers who needed something pizzazzie for a trade show. Cablevey is an international leader in puck conveyance and uses our tubing for sight...
Nature loves logarithmic spirals and so do I. Back in my junior year of high school, I had a fabulous earth-science teacher who taught us how to do scientific research on foraminifera growing around heat "enrichment" zones from power plants in the Northern Shore of...
A customer in New Jersey had an immediate need to replace his PVC offset bend. He was transferring a powder through it and was running into packing by the tight radius 45° elbows. He could not send us the bend and for a variety of reasons could not provide us...
We received a challenge from a customer who needed to convey closures through a labyrinth of machines, fixtures, and clearances to get to the loading bin. The trick involved a rectangular twist. Rectangular twists provide a change of orientation of closures (lids in...
Tight –radius bends are a problem to all tube benders. On a tight radius, we can run into excessive flattening, cracking of the outside wall, or buckling in the inside wall (most commonly). The problem is intensified in transparent, thermoplastics benders, for we do...
We can bend to almost any design. Here, we received a challenge from a breakfast nook company for a three-dimensional bend on a 3.259 OD Tritan tube. Pictured here is the model, we cannot show the final piece. The drawing shows the challenge. Here is the result....
We were recently asked to make an offset of a 5" Sch 10 Tritan pipe. While Tritan has excellent Mechanical, Optical and Thermal Properties, it takes some skill to bend it. Offsets are particularly difficult, but here we have a Tritan bend in its cooling blocks.
