Structure Fittings Base

Base fittings are critical components for anchoring vertical tubes in glass support systems, pilot plants, and industrial modular frameworks. They provide a rigid foundation, precise leveling, and load transfer to the structure beneath.

Overview

The base fitting serves as the primary anchoring point for vertical structural tubes. It ensures the entire support system is aligned, stable, and capable of carrying the weight of glass columns, vessels, or piping networks. By using purpose-built base fittings instead of generic flanges, installation is faster, safer, and more accurate.

Material Options:

• Cast iron (robust and durable)
• Mild steel (galvanized or epoxy coated)
• Stainless steel 304/316 for corrosion resistance in chemical or humid environments

Applications:

• Laboratory glassware support systems
• Pilot plant column foundations
• Modular vessel and bellow frameworks
• Chemical, pharmaceutical, or research installations
• Heavy-duty industrial glass plant supports

Catalogue Base Models & Dimensions

Function & Interface

• Interfaces with the matching tube diameter to receive vertical tubes.
• Pre-drilled holes allow secure anchoring to concrete or foundation slabs.
• Height ensures correct elevation above the foundation for leveling and grout clearance.
• PCD (pitch circle diameter) aligns with foundation bolt layouts for accurate installation.
• Allows integration with lateral bracing or modular structures for overall stability.

Installation Guidelines

1. Tube Insertion: Fully seat the vertical tube into the base fitting.
2. Alignment: Ensure the tube is perfectly vertical before tightening.
3. Anchoring: Use foundation bolts to secure the base to a rigid substrate.
4. Grouting: Apply grout under and around the base to distribute loads and maintain levelness.
5. Lateral Bracing: For tall or heavy assemblies, integrate with cross braces or tie-downs.
6. Environmental Considerations: Choose stainless steel or coated base fittings for corrosive or humid conditions.

Key Features

• Provides rigid foundation for vertical tube assemblies
• Pre-drilled for accurate installation with bolts
• Compatible with modular frames and structure tubes
• Available in galvanized, epoxy-coated, and stainless steel
• Supports high load-bearing capacity for vessels, columns, and pilot plant units
• Designed for precision leveling and grouting

Applications

Base fittings are used in:

• Foundation mounting of glass column support frameworks
• Fixed support for vessels or piping in pilot plant setups
• Modular support frameworks in laboratories and chemical plants
• Heavy-duty industrial applications requiring accurate alignment and rigidity
• Retrofitting existing glass or pilot plant structures

FAQs

Q1: Can I use base fittings for both galvanized and stainless steel tubes?
A1: Yes, base fittings are compatible with standard NB tube sizes across both materials. Stainless steel is preferred for chemical or high-humidity environments.

Q2: How do I ensure the tube stays vertical during installation?
A2: Use jacking rods or temporary braces to align the tube before tightening foundation bolts.

Q3: Can base fittings support tall glass columns?
A3: Yes, provided the frame includes lateral bracing and appropriate tube sizes. Taller assemblies may require additional counterbalance supports.

Q4: Are custom base fittings available?
A4: Yes, custom PCD, bolt hole size, or height (H) can be manufactured per client requirements.

Q5: How do I prevent corrosion?
A5: Mild steel base fittings should be galvanized or epoxy coated, while stainless steel 304/316 is ideal for aggressive environments.
