Circular Bend

Tubing That Holds Under Pressure

Building a Flow Loop with Clear Rigid Plastic Tubing and NPT Threads We were recently contacted by a Ph.D. student working on a multi-phase flow problem. The application called for a clear rigid tubing flow loop that would maintain a circular shape under pressure with...

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,...

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...

Hoop Skirt

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...

Coffee Roaster

In July we received a print to bend tubing for a trade-show coffee roaster display. We had two weeks to meet a deadline. We elected to make the bends out of a 3″ OD butyrate tubing with a .125 wall. The bend radii were as tight as 8″ CLR. Dry ice worked as...

Lighted LED Bend With Proper Annealing

Recently we had a request to make circular and helical small diameter bends for a lighting project. We designed special heaters for the project and made our prototypes with clear, transparent CAB (butyrate). The trick is proper annealing. We not only heat our bends to...

Knock Knock Helix

The Knock Knock children’s museum in Baton Rouge is set to open this August. We are delighted to have participated in one of the principle attractions, the pneumatic tube carrier exhibit. Designed by Zaphod Beeblebrox, the helix consists of a a spiral of 60...

Jerry Garcia And Busada Tubing

Helix

We are privileged to participate in a helical bend for a children’s museum in Baton Rouge. More later as this develops. The helix (hexagonal) has a 96″ radius and composed of (CAB) cellulose acetate tubing (4.125″ID).   Model 1 and support...
