Structure Fittings Support

Support fittings (designated as SPT series) are used to provide auxiliary, lateral, or secondary support connections from a main structural tube. These fittings allow side arms, brackets, or small support members to be attached without imposing excessive load on the primary structural or glass-handling framework.

The fitting slides over the main galvanized tube and is locked in position using grub screws, allowing flexible positioning along the tube length. A perpendicular support arm or rod is accommodated through the defined d-diameter port, enabling attachment of instrumentation, piping clamps, cable trays, or light structural members.

Support fittings are widely used in glass plant support structures, laboratory frames, and process equipment installations, where modular adjustability and controlled load transfer are required.

Catalogue Models & Dimensions

Dimension Notes:

• NB: Nominal bore of the main structural tube
• h / L: Engagement and support geometry dimensions
• d: Diameter of the auxiliary support arm / rod opening

Material & Construction

• Standard construction in cast iron
• Optional stainless steel (SS 304 / SS 316) for corrosive or humid environments
• Internal bore matched to tube outer diameter for secure sliding fit
• Grub screw locking mechanism for positional stability
• Compact geometry to minimize obstruction in dense structural layouts

Functional Role in Structural Systems

Support fittings are designed to offload secondary or non-axial loads from the main frame. Instead of stressing primary structural members, these fittings provide a controlled interface for:

• Hanging auxiliary equipment
• Supporting instrumentation
• Mounting piping or cable supports
• Providing intermediate bracing points

Their modular nature allows easy repositioning, making them suitable for evolving plant layouts.

Design Considerations

• Ensure sufficient overlap of the fitting on the main tube for rigidity
• Verify side load capacity on the d-dimension support arm
• Avoid excessive cantilever loads without additional bracing
• In vibration-prone installations, ensure grub screws are properly torqued
• Use stainless steel variants in chemical, coastal, or high-humidity environments

Typical Applications

Support fittings are used when:

• Side arms or auxiliary loads must be mounted on a primary frame
• Instrumentation, sensors, thermowells, or gauges require structural attachment
• Piping clamps or lightweight process lines need intermediate support
• Partial bracing or lateral stabilization is required at mid-span locations
• Adjustable support interfaces are preferred over fixed welded joints

Key Advantages

• Modular and adjustable installation
• No welding or permanent fabrication required
• Controlled load transfer away from glass or process equipment
• Compatible with standard structural fitting systems
• Suitable for both permanent and reconfigurable installations
