Bend fittings for directional changes in structural support systems.
Structure Fittings Bend Overview
Bend (elbow) fittings allow the structural frame to change direction, forming corners or offsets. These bends slide over vertical or horizontal galvanised tubes and are fixed in place with grub screws. The design enables smooth transitions in frame layout without welding. Standard catalog references include BN25, BN30, BN40, and BN50, specifying the nominal bore size (NB) and corresponding dimensions (H and L). These bend fittings integrate seamlessly with other structural fittings in a modular support system, helping maintain rigidity while allowing geometric flexibility.

**Catalog Models & Dimensions**
| Cat.Ref. | NB (mm) | H (mm) | L (mm) | |—|—|—|—| | BN25 | 25 | 50 | 55 | | BN30 | 30 | 65 | 70 | | BN40 | 40 | 70 | 80 | | BN50 | 50 | 85 | 95 |
**Material & Assembly**
– Cast iron construction, optionally stainless steel
– Internal bore dimensioned to slide onto corresponding tube
– Fixed by grub screws after alignment
**Design Considerations**
– Radius and length must match frame geometry requirements
– Ensuring overlapping tube engagement for strength
– Use in combination with bracing to manage bending or torsional loads
– Proper selection avoids introducing stress into connected glassware
Applications
Bend fittings are used to shape and route structural support frames in glass plant installations, such as:
– Forming corner joints or changes in direction of support tubes
– Creating framework offsets around obstacles or process equipment
– Integrating structural support paths around vessels and piping
– Assisting in modular reconfiguration of support grids
– Enabling continuous support paths without welding or over-stress on glassware
