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...

Our Static Dissipative Coating

We now have an option for a hard-baked static dissipative coating for our transparent tubing. Most plastics do not give up their electrons easily; they are insulators. And since they are insulators, they are poor conductors of electricity. Thus, electrical charges can...

Is Butyrate an Antistat?

Is butyrate an antistat? We get this question often, and the answer is 'at times' and 'no.' Every winter we receive calls asking for help with static buildup in pneumatic systems. Lower humidity brings an increase in static electricity. In pneumatic systems, you can...

Supporting Tubing

In any pneumatic tubing system, the installer must choose not only the pathway of the tubing, the radius of the bends, and airspeed, but also support. One can support the tubing by many means but sometimes the engineer needs to accommodate for a long span. In cases...

Easy Pneumatic Access Port

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...

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...

Connecting Butyrate Sleeves Cone Set Screw Method

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...

Coupling Dissimilar Plastics Tubing

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...

Cutting Bends Through The Arc

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...

Dealing With Angel Hairs In Pneumatic Tubing

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...

Does Butyrate Stink?

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...

Sectioned Circular Bend

Whenever I hear of a "circle within a circle" I think of the bizarre description of deity in Ezekiel Chapter 1 (well, in his case it's a wheel within a wheel). In our case, it's a prototype. And it was a challenge. We were to produce an air-tight, water-tight...
