This week we had a challenge. A customer ordered a specialty bend with 4 inch ID on a 20” Outside Radius. The bend was to have an extended tangent on one side of 15” and a short tangent of 1.125”. The customer wanted to put the bend directly into a chute for their...

Busada extrudes Butyrate (CAB), and Tritan pipe in nominal sizes from ½” to 8” and in Sch 10, 40, and 80. We extrude other schedules to order. The picture below is from a recent run of Butyrate 6” Schedule 80 Pipe. Our customer’s engineer was not happy with the...
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...
A 5-man team of senior mechanical engineering students at the University of Missouri contacted us for their required capstone design project. They were to build a functioning model of a coal log pipeline design which was patented by two Mizzou professors back in the...
Our LED tubing was put to a beautiful use with Objects of Common Interest in a Brussels display. The architects chose our line of Stratus tubing (6" OD). The project came to us first in concept, design, and fabrication. The material used to produce these lights is an...
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...
When we first received an inquiry into making tubing for a banking commercial we were amused. And, from their animations, we knew that this was going to be fun.The project had its challenges though. The production company had no experience in pneumatic conveying but...
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 have extruded oval tubing for over a decade, but this is the first time we extruded it in our PETG (Provista) formulation. PETG has some advantages over CAB in that it is FDA and NSF compliant with food contact, and our employed formula has passed the NFPA 286...
Mandy McGarrigle, an emerging young fashion designer, requested a clear plastic hoop as an accessory in a fashion show. She needed a 1" OD tube with a thin wall bent upon a 12.625" center radius. We are used to providing prototypes and we went to work on her bend....
