Structure Fittings Cross

Structure Fittings Cross

A Glass Structure Fittings Cross (X-series) is a four-way in-plane joint used to connect structural tubes at a central point in support frameworks for borosilicate glass process equipment. Goel Scientific manufactures these fittings in cast iron, hot-dip galvanised iron and stainless steel, with sizes suited to standard structural tube diameters. The cross provides a rigid 90-degree intersection for horizontal grid frameworks supporting glass reactors, distillation columns and pilot plant assemblies. Each fitting is machined for consistent internal bore dimensions and inspected for dimensional accuracy before despatch. Custom tube diameters, materials and specialised finishes are also available for non-standard project requirements.

Key Features

  • Four-Way In-Plane Connection: Glass structure fittings cross joins four tubes at a shared central junction point without requiring welding or hot work.
  • Symmetric 90-Degree Geometry: All four sockets are machined to precise angular tolerance to maintain squareness across multi-axis support grids.
  • Efficient Load Distribution: Central node handles reactions and load paths from four directions simultaneously.
  • Tool-Only Installation: Grub screws lock tubes securely into position once aligned, ensuring fast, modular assembly and easy future expansion.
  • Robust Material Options: Cast iron standard construction, with hot-dip galvanised iron and stainless steel (SS 304 / SS 316) versions for aggressive environments.
  • Bore-Matched Precision: Internally bored to fit tube outer diameters perfectly, ensuring maximum structural contact.

FAQs

A structure fittings cross is used to connect four structural tubes at a shared central point in support frameworks for borosilicate glass process equipment. It handles four-way load transfer in a single symmetric component.

A Glass structure fittings cross transfers loads from four directions into a single central node, keeping the framework rigid and preventing cumulative alignment errors across multi-axis grids.

Tubes slide directly into the internally bore-matched sockets of the cross fitting and are locked rigidly into place using high-tensile grub screws, eliminating the need for field welding or drilling.

Yes, cross fittings are frequently used in glass column support structures at heights where lateral bracing must be provided in four directions to keep the column vertical and stable under process loads.

Yes, Goel Scientific manufactures the structural fittings cross in cast iron, hot-dip galvanised iron, and stainless steel 304 and 316 variants, accommodating nominal tube diameters from 25 mm to 50 mm as well as custom requirements.
