Bends

Fruit Chute

Recently we were given the challenge to produce a tight radius bend to replace a metal fruit chute (peaches). The bend needed a 6" ID and a tight 12" radius. We were able to accomplish this by flaring a 5" ID tube to 6.5" ID and bending the tube 3D to come under the...

Blue Star Bends

For top-of-the-line clarity in bends, nothing comes close to our Provista (PETG) line with monitored air packing. For clarity one has to control the packing material. This method was developed for a line of retail-coffee-house bends. Nothing is clearer, and this...

Six Degree Butyrate Bend

In our helix design we needed to modify the entrance and the exit of the banking tube carrier. The helix rises at an angle of about 6 degrees, and so we needed a 6 degree bend to level it out. In over 60 years of bending butyrate, this is certainly the smallest angle...

Roasting Plant Pneumatic Art

We have been making bends for The Roasting Plant as they build new and upgrade existing restaurants. They and their engineers from Advanced Design (FL) have tight tolerances and every bend is different. We extrude Provista tubing (PETG) and coat it with our ACS...

Candy Cane Bend

A conveyance company occasionally orders candy-cane bends. The last order was for a tight 18" Radius on a 4" OD 180 Deg tube. It takes a certain technique to make these kinds of bends and to avoid the stresses that would generally pull the bend inward or outward....

Tight Radius Bends VS. Elbows

Problem: We had a challenge to produce a 4"CLR bend in our 1-1/2" pipe in clear, transparent, Provista (PETG). Provista is very clear, has NSF approval for food contact, no odor, and very good chemical resistance. But, it has a very short transition temperature in...

Just Another Bend

We make bends. We make helices, U bends, offset snake bends and all in between. This week we had a challenge. We were to make a large diameter 6.525" ID Bend on a 69" Center-Line-Radius with a tolerance of +-0.5Deg, and 8" tangents. If that was not enough, we were to...

Provista Bends And Sleeves

We recently filled an order with specialty bends for Provista (PETG) UVO. This clear, transparent conveyance system is UV stabilized and FDA/NSF approved. We also supplied sleeves for the order. In order to maintain NSF standards, the sleeve is thick-walled. This...

Rectangular Helix

Currently, we are preparing for a rectangular helical bend for a cup company. They are conveying squat cups and want a holding area for them. Thus, their engineer wants a 2 tier helix where the cups will travel in a vertical position. This would require the "hard bend...

Round To Rectangular II

Earlier we posted on our ability to fabricate rectangular tubing from our stock round Busada 200 Tubing. Recently we had a request to a 4.375 x 3.375" rectangular tube for a prototype test for pneumatic conveyance of squat paper cups. This is an inexpensive...

Space Station Bend

Do you need an off-the-charts bend of transparent tubing? How about a 14° 200" R (no tangents)? We received an interesting call this week. A school is preparing a model of a space station to be displayed at NASA. Our little part in this was to scale down a 12 ft...

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...

Round To Rectangular Tubing

Often our customers need a specialized rectangular tube, but not enough to justify the expense of tooling and an extrusion run. Our answer is to fabricate from round. Recently, a customer needed a simple 4" x 5" rectangular tube and bend. By secondary fabrication...

PETG Bends

Busada makes long-radius sweeps (bends) in CAB (butyrate), Provista, Polycarbonate, and PVC, but recently completed its first PETG bend. The bend was on a 24" Radius with extended tangents. All bends are made to order, with a 10 point check to see that degree, radius,...
