Rectangular Tubing Bend Guide

Rectangular tubing bend orientation can be confusing. Many simply call the two options the “hard way,” and the “easy way.” We designate two planes of rectangular-tube bending: Y, (around the Major axis) or X= around the minor axis. Our rectangular bends are used, by...

Offset Bends

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...

P-Trap Bends-Small Diameter Tubing Bends

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...

U Bends

We frequently 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...

Zero Tangent Bends

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...

More Tight Radius Bends

Here above we have an example of a larger OD tight-radius-bends. This one is a 4.750 OD tube bent on a 13" center-line radius. You will notice that the right side of the bend has an extended tangent and the accuracy of the bend is measured by the inside wall...

How To Identify The Bend In Rigid Tubing

It happens a lot; don't feel bad. You may not know the exact angle, nor the radius of the bend; you just know that you need the exact replacement fast. This blog will explore several ways to identify your bend, but we start out with the most painless way devised by...

Elbows For Caps

Angel hairs and tube abrasions are the nemeses of cap and closure conveyance. On Apr 1, 2009 Shrikant Dhodapkar (and others) published "Understanding Bends in Pneumatic Conveying Systems" in Solids Processing. The document is widely available online. The article has...

Find Your Radius

How to identify the radius of a bend for a bend less than 180 Degrees. Imagine if you got a picture like this in your email and your customer said, "make us one just like this." On top of that, they insist that this is a bend on a 24" radius. They can't ship you the...

Fitting Bends To Your Needs

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...

Clear, Rigid Transparent Butyrate Pipe VS. Clear PVC Pipe

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...

Fitting A Bend From A Distance

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...

Water Sediment Tester With Butyrate Pipe

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...

Tight Radius Large U-bend

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...
