Structure Tubes

Galvanized Structural Tubes provide robust, corrosion-resistant support for modular frameworks in glass plants, laboratories, and pilot plant installations. These tubes form the primary skeleton for column supports, vessel support systems, and general structural assemblies.

Overview

Galvanized structural tubes are manufactured in mild steel (B-class) with galvanizing or epoxy coating, as well as stainless steel (304/316). They are used to create rigid, modular, and reconfigurable frameworks for chemical, pharmaceutical, and research equipment. The precision-cut tubes are compatible with cast iron, stainless steel, and aluminum fittings, making assembly and expansion straightforward.

Key Features

• Material Options: Mild steel (galvanized/epoxy coated), stainless steel (304/316)
• Corrosion Resistance: Galvanized coating protects against moisture and chemical exposure
• Standard Nominal Bore Sizes: ½″, 1″, 1¼″, 1½″, 2″
• Customizable Cut Lengths: Vertical tubes up to 6,000 mm; horizontal members from 400 mm to 1,500 mm
• Rubber End Plugs: Prevent ingress of dust, debris, and moisture
• Modular Compatibility: Designed to integrate seamlessly with catalogue fittings (tees, bends, couplers, brackets)

Tube Sizes & Dimensions

Available Cut Lengths:

• Vertical installations: up to 6,000 mm (depending on NB size)
• Horizontal / cross members: 400, 500, 600, 800, 1,000, 1,200, 1,500 mm

Installation Guidelines

1. Frame Planning: Ensure tubes are selected according to load, span, and vessel/column dimensions.
2. Tube Alignment: Place vertical tubes on base supports; verify plumb alignment.
3. Bracing: Use horizontal cross tubes, tees, bends, and brackets to prevent lateral deformation.
4. Fixing: Secure fittings with grub screws or bolts; check for tight connections.
5. End Protection: Leave rubber plugs in place during installation to protect interior tube surfaces.
6. Future Expansion: Use modular fittings to allow addition of new frames or retrofitting equipment.

Applications

Galvanized structural tubes are ideal for:

• Vertical column support frameworks for distillation, absorption, or extraction setups
• Cross-bracing and frame structures for glass reactors, vessels, and instrumentation
• Modular laboratory and pilot plant installations requiring reconfiguration
• Environments exposed to chemical, humidity, or condensation, providing corrosion protection
• Replicable modular supports in academic, research, and industrial pilot setups

Structural Considerations

• Tubes should be integrated within rectangular or lattice frames to avoid buckling
• Tube NB and length must correspond to anticipated load and structural span
• Ensure compatibility with existing or new fittings to maintain stability
• Avoid unsupported horizontal spans exceeding recommended lengths without cross-bracing
• Galvanized coating may degrade under extreme chemical exposure—consider stainless steel 304/316 for aggressive media

FAQs

Q1: Can galvanized tubes be used outdoors or in humid labs?
A1: Yes, the galvanizing layer protects against corrosion, moisture, and light chemical exposure. For highly aggressive chemicals, stainless steel tubes are recommended.

Q2: Are these tubes compatible with modular fittings?
A2: Absolutely. All tubes are compatible with cast iron, stainless steel, and aluminum fittings from the catalogue.

Q3: How do I choose the correct tube size?
A3: Choose tube NB based on load, column/vessel weight, and frame span. Refer to our structural design charts.

Q4: Can tubes be cut to custom lengths?
A4: Yes, we provide tubes cut to required lengths for vertical, horizontal, or cross-member applications.

Q5: How do I maintain galvanized tubes?
A5: Regularly inspect for surface rust or wear. Clean with mild detergent and avoid prolonged contact with strong acids or alkalis.
