Structure Fittings – Double Bend

Structure Fittings – Double Bend

A structure fittings double bend is a multi-leg angled joint used to route structural tubes around obstacles while maintaining framework continuity. Goel Scientific Glass Works Ltd. manufactures these fittings in cast iron, hot-dip galvanised iron and stainless steel (SS 304/316) for support structures used with borosilicate glass reactors, distillation columns and heat exchangers. The double-bend design helps redirect tubes around walls, utilities and existing equipment while maintaining structural strength. Goel Scientific uses certified raw materials and consistent socket dimensions matched to tube sizes. Each fitting is dimensionally inspected before dispatch, with custom bend angles and tube diameters available on request.

Key Features

  • Multi-Leg Directional Routing: Structure fittings double-bend routes tubes around obstacles and create parallel offset paths with a single rigid component.
  • Precise Angular Tolerance: Consistent bend geometry ensures framework alignment and load continuity across the full assembly.
  • Tool-Only Installation: High-tensile grub screws secure tubes into sockets without welding, drilling, or hot work.
  • Corrosion-Resistant Material Options: Cast iron or galvanised iron for standard duty, and stainless steel for aggressive environments.
  • Modular Compatibility: Fully compatible with standard galvanised structure tubes and the complete Goel Scientific structural fitting product line.
  • Custom Engineering: Non-standard angles, non-standard tube sizes, and custom socket lengths available on request.

FAQs

A structure fittings double bend is used to route structural tubing around obstacles, create parallel offset paths, and change framework direction in support systems for borosilicate glass process equipment.

It provides a multi-leg directional offset in a single component, eliminating cumulative alignment errors that occur when chaining multiple single-bend fittings together.

Yes, structure fittings double bend sockets are engineered to match standard nominal bore tube diameters (NB 25 to NB 50). Internal bores fit snugly over tube external diameters and lock securely using grub screws.

Standard models feature a durable cast iron body with hot-dip galvanised coating, while stainless steel 304/316 variants are available for high-corrosion environments.

Yes, Goel Scientific manufactures double bend fittings in non-standard tube diameters, custom bend angles, and specialised socket lengths upon request.
