Had a visitor in my office this morning. Poor fella, he had spent the entire weekend in a self imposed terrarium. He was pretty shook up, but we removed him to the great outside and gave some nutty treats and water. After a few hours he went his own way. He ate a bit...

Here is an illustration showing our method of fabricating 90° ells from a straight section of CAB Tenite clear extruded butyrate pipe. This example is from 4" Sch 40 pipe. The ends of the two pieces to be joined are cut on a 22½° angle. A short filler cut with the...
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...
We recently had an inquiry regarding a transparent easy access port in their pneumatic tubing lines. Our simple solution is to install, wherever necessary a grouping of two axial-slit sleeves and a removable tubing section. The sleeves are to be mounted by hose...
Does butyrate stink? It’s a misguided question and we get it all of the time. Our basic answer is "No, butyrate does not stink; butyric acid stinks.” We extrude CAB tubing: Cellulose Acetate Butyrate formula 576E (with odor mask). Frankly, next to common acrylic it...
Purpose Protection, ready visibility, and ease of access are three conditions desired of sluice gate, valve stem, slide gate, and weir gate protectors. Before transparent butyrate covers, these were particular problems. The traditional protection employed galvanized...
Dealing with Angel Hairs Angel hairs in pneumatic conveyance is a longstanding problem. It certainly is not welcome in transparent tubing. Angle hairs are described by Theile as "those fuzzy, fitful, filmy pieces of plastic that drive us crazy, and. there is nothing...
We recently received an inquiry on how we cut bends through the arc (remove the tangents). We basically do it two ways, with a Marvel, tilt frame vertical bandsaw or through a Conair up-cut saw. With pneumatic pistons, the saw holds the bend snugly (notice a...
Sometimes our customers need to couple dissimilar plastics tubing. Most often they couple provista (PETG) tubing with butyrate (CAB) sleeves. We recommend this technique. It is simply using the molding shrinkage of a heated tube to form a compression coupling. After...
Besides solvent welding, there are several other methods to couple your Flares and Bells to our tubing. Many of our customers want to easily access sleeves and couplings for cleaning of the pneumatic line. Axial Slit and Hose Clamp: We simply provide four .125" axial...
Today we had a request for an expanded sight glass/coupler. This is an easy blog to write because we don't have any idea what this is being used for. Yet, it made a nice picture and it's just one more for the record. We made this by a special process we developed to...
Fiber-reinforced concrete has been rapidly growing throughout the building industry. Polypropylene fiber can increase toughness and durability of residential concrete. These synthetic fibers need to be uniformly distributed within the mix. But macro-synthetic fibers...
One simple way to connect your butyrate sleeves is using four to six cone set screws. Simply mark the spot from 1.5 to 2" from the end of the sleeve. Drill, tap, and lightly torque. The set screws will bite into the tubing. They can be removed for cleaning and...
Busada Mfg. Corp has been manufacturing and selling clear transparent tubing for over 70 years. Only in the last 5 years have we added colors, and so it's been more colors every year. It's about time we wrote a blog on some ways that we can color our tubing. First, we...
