Structure Fittings Tee

Structure Fittings Tee

A structure fittings tee is a three-way modular joint used to connect structural tubes at right angles in support frameworks for borosilicate glass process equipment. Goel Scientific Glass Works Ltd. manufactures these tees in standard cast iron and stainless steel variants, with sizes matching standard Nominal Bore (NB) structural tubes. They are suitable for supporting glass reactors, distillation columns, heat exchangers and pilot plant assemblies. Designed for tool-only installation, the tee requires no welding. Each fitting is manufactured from certified raw material, precision-machined for a smooth tube fit and dimensionally inspected before dispatch. Custom sizes are also available for non-standard tube diameters.

Key Features

  • Three-Way Rigid Connection: Structure fittings tee connects three structural tubes at right angles for robust framework construction and multi-directional load path distribution.
  • Tool-Only Installation: Internal bore slides onto matching galvanised tubes and is locked into place via grub screws without welding, drilling, or hot work.
  • Consistent Socket Dimensions: Precision-machined internal diameters match tube outer diameters (OD) for perfect alignment and interchangeability across the product line.
  • Corrosion-Resistant Finishes & Materials: Cast iron construction standard, with optional stainless steel variants and hot-dip galvanised or electropolished surface finishes.
  • Modular and Reconfigurable: Frames can be disassembled, modified, or expanded mid-installation during maintenance or plant upgrades.
  • Custom Sizes Available: Non-standard tube diameters and specialised configurations supplied on request for specialised installations.

FAQs

A structure fittings tee is used to create 90° branch connections and connect three structural tubes at right angles in support frameworks for borosilicate glass process equipment. It provides a rigid three-way joint suitable for corner intersections and branch points in modular skeletons.

A structure fittings tee distributes loads and shear forces across three axes simultaneously, giving the framework rigidity in all directions. Precision-machined sockets ensure the connected tubes stay square and aligned, preventing cumulative misalignment that would stress the glass components.

The fitting slides directly onto matching galvanised tubes and is locked firmly into position using wrench-tightened grub screws, eliminating the need for welding or drilling.

Goel Scientific manufactures structure fittings tees from high-grade cast iron as standard, with optional stainless steel (SS 304 / SS 316) variants available for highly aggressive or cleanroom environments.
