Tubing Applications

New Bells For 20′ Length Tubing

PVC pipe often comes standard with bell ends on one side. You can also order belled ends on our Butyrate, Provista (PETG), and Polycarbonate tubing. We have a new process that allows us to make bells to order on hundreds of sizes in small quantities. Thus, tooling and...

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...

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...

Tritan Tubing, The Largest Anywhere

Tritan: Our first extrusion of Tritan tubing was big in itself. It produced the largest Tritan tube in America to that point. The 5" OD x .250w tube was designed for a home-consumer company. Now we extrude Tritan up to 10" in diameter. Tritan is a monster tube. It has...

Tube Cutting

Depending on the wall thickness and tolerance (length and squareness) we can saw cut, core cut (blade), or lathe cut tubing to length. [TABLE] Blade cuts are very square and have a soft feather edge (no sawdust). The feather edge is a result of heat generated from the...

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...

Will The Circle Be Unbroken

A Spanish museum contacted us to see if we could fix a work of art. The actual artwork is an elaborate set of collars that connect small-diameter tubing bent on a tight-radius circle. They sent us a sample of an acrylic tube. Acrylic is famous for cracking, crazing,...

Rectangular Tubing Upgrades in Clarity

Rectangular transparent tubing formed in an extrusion vacuum system has some inherent problems in clarity. For one, the vacuum sizer heads need extra length to combat the vacuum's tendency to round the tube. This tends to introduce draglines and chatter marks. We have...

Flare VS. Bell

The nomenclature of bells and flares varies throughout the industry. We follow a simple definition. 1) A flare is a sloping expansion of a tube. They assist in guiding an object or carrier into the pneumatic tube system. Flares are usually defined by the ID, angle,...

Frosting Stratus Tubing

Our Stratus line is used for LED lighting. Recently we received a request for a frosted tube. The link below gives Eastman's response, but for small extrusion runs we have a Per-Fix solution from Chem Pak. We have other methods, but the Per-Fix 6500 method is ideal...

Funnel Flares Sleeves And Couplings

This week our challenge was to make a simple funnel flare-- 3” ID tube to a 4” ID tube. The trick was to do it without tooling. The cup manufacturer company wanted only three flares to put at cup entrance points of its pneumatic transport system. Busada makes all...

Colors And Hula Hoops

While we're known for clear, transparent plastics tubing, we do more. Busada has extruded PVC, black ABS, and colored CAB. Last month we set out to run a rainbow of colors from black, red, greens, blues, yellows, and colors in between for a musical piping project....

Colors And More Colors

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...
