Structure Fittings
Structural fittings for connecting and assembling support frameworks.
Structure Fittings Overview
Structure fittings form the critical junctions and connection points for tubular frames in glass plant support systems. Manufactured in cast iron (with optional stainless steel 304 / 316 variants), these fittings slide over galvanised tubes and are secured in place with grub screws. Their modular design enables construction without welding or hammering, facilitating future reconfiguration or retrofit. These fittings ensure a tight, adjustable interface between tubes, brackets, bends, and other structural components while preserving the integrity of the glassware system. Because the fittings can be repositioned and locked in place, they support flexible layout and modular expansion of the support framework without the need for on-site metal fabrication. This flexibility is especially useful in pilot plants or evolving systems where slight adjustments may be needed.
Specifications
**Materials & Variants**
– Standard material: Cast iron, with option for stainless steel (304 or 316) for corrosive environments
– Surface & finish: As cast, with machining where needed for grub screw holes and internal bore tolerances
**Design & Features**
– Slidable over the matching tube external diameters and fastened with grub screws to lock position
– Designed for ease of assembly and future modification: no welding or hammering required
– Compatible with the full range of tube sizes (½″, 1″, 1¼″, 1½″, 2″) in the associated support tubing line
**Fitting Types (as per catalogue)**
– **Base fittings**: for vertical tube anchoring, include holes for foundation mounting
– **Couplers**: join two tube segments to extend length (e.g., CL25, CL30, CL40, CL50) with dimensions H and H1 specified
– **Bends / Elbows**: used to change direction in frame geometry (BN25, BN30, BN40, BN50)
– **Tees / Cross / Double-tees / Double bends**: to create branch connections in frame grid
– **Brackets / Supports** (equal, unequal) for offset or angled support arms
– **Plugs**: to cap open ends of tubes (PLUG sizes for NB 15, 25, 30, 40, 50)
– **Studs**: threaded rods for attachment of additional supports (STUD5/16-150, STUD3/8-150, STUD1/2-200)
**Structural Guidelines**
– Fitting internal bores match external diameters of tubes to ensure snug fit
– Grub screws must be tightened after frame alignment to ensure rigidity
– For heavier loads or larger spans, additional bracing and firmer joints are recommended
– Select stainless variants in corrosive or high-humidity environments to reduce corrosion risk
Applications
Structure fittings enable versatile frame assemblies across glassware installations including:
– Building support frames for glass columns, vessels, and pipelines
– Creating cross-connections, braces, and support brackets in a modular support grid
– Retrofitting or altering support geometry mid-project without welding or cutting
– Facilitating modular laboratory or pilot systems where ease of adjustment and modularity are essential
– Locations where mechanical integrity and stiffness are required in compact configurations
