Solvent Welding

Solvent Welding Butyrate Tubing

1. Solvent-welding butyrate tubing requires, well, a solvent (acetone alone will do it), some butyrate resin, a jar, and a brush. 2. We can provide you with some "fines," or you could cut some of the tubing scraps and generate some clean butyrate sawdust. 3. I like to...

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...

Custom Air Filter

When a request for a custom air filter came in with an associated drawing we got to work. The original print imposed an untenable bend upon the 2″ OD butyrate tube, so we suggested mitering.After a bit of back and forth, we suggested another change. As this...

Tight Radius Mitered Pipe Bends

We recently had quite a challenge from Metraflex regarding a transparent tight-radius 4” pipe 90° bend. They required a transparent 4” Sch 40 long-radius elbow to observe a metal fin in a fluid system. The pipe bend needed to maintain a tight tolerance for ovality as...

Flotation Bend

We have manufactured butyrate tubing for marina docs, oceanic core tubes, and other aquatic uses but here is a first. It is a butyrate flotation bend. The bend was sectioned together with butyrate discs and solvent welding before the bending process. We achieved the...

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 circle.Ideas on...

Mighty Mite – Custom Rigid Extruded Tubing

Problem: Extrude a heavy-walled small diameter pneumatic tube; in this case the wall area composes 75% of the tubing area. The difficulty comes in maintaining wall uniformity while eliminating “lensing,” uneven cooling, uneven shrinkage (curling) and chatter lines....

Tees, Wyes, And Branches

Often in pneumatic conveyance, one needs to bring two lines together. In such cases, transparency offers obvious advantages; a transparent connector immediately shows a visual of the area most likely to jam. At Busada we have made various Wyes and other connectors for...
