Connecting tubes– all methods and tube connection variants at a glance

Connecting tubes is key when it comes to modular tube systems, scaffolding, or assemblies. At INOCON, you will find a wide range of solutions—whether with detachable tube connectors, clamping or plug-in systems, or classic, fixed connections. Every application requires the right method: whether static-structural, temporary, or modular.

To the product overview

Why is the choice of connection crucial?

Tubes serve as hollow profiles with a consistent cross-section – they can be statically loaded elements or media lines. Depending on whether stability or tightness is required, the appropriate connection technology differs significantly.

 

  • For media lines (liquid or gas): Tightness is crucial → welding, flanging, pressing, soldering, etc. are often necessary.
  • For static-structural systems (scaffolding, modules, assemblies, etc.): Detachable, modular connection systems (clamp/plug connectors) are often sufficient and significantly more flexible.

Overview of tube connection types

Permanent connections

  • Welding
  • Soldering
  • Flanging
  • Pressing
  • Bonding

     

These methods create durable, usually tight connections — ideal for permanent piping systems.

 

Detachable and modular connections – with tube and clamp connectors

INOCON offers a wide range of detachable connection solutions that are ideal for modular tube systems. These include:
 

  • Tube or clamp connectors made of aluminum or stainless steel
  • Sleeve, plug-in, or clamp connections
  • Angle, T, cross, joint, or adjustable connectors depending on the design
  • Plug-in or clamp connections for round and square tubes

 

These solutions allow tubes to be connected flexibly without the need for heat, special tools, or welding/soldering skills, and to be disconnected again if necessary

 

Materials & tube profiles – what options are available?

Metal & stainless steel tube connectors

Robust connectors made of metal or stainless steel are suitable for load-bearing structures or demanding conditions.

Stainless steel clamp connectors are particularly popular when corrosion resistance or high durability are important.

Aluminum connectors

Lightweight construction and flexibility: aluminum tube connectors are a good choice for temporary structures, lightweight frames, or modular systems.

Tube profiles – round tubes & square tubes

INOCON covers both round tubes and square tubes up to 600 cm. Both tube profiles can be connected securely and flexibly using suitable clamp or plug connectors.

When to choose tube connectors instead of welding?

Advantages of detachable tube connections

  • Quick, low-tool assembly
  • Flexible adaptation and expansion of systems (ideal for modular constructions and prototypes)
  • Reusability for conversions or dismantling
  • No heat influence on material, no welding work necessary

 

When are classic connections useful?

  • For permanently sealed media lines (e.g., liquids, gases)
  • For fixed structures under high static loads without any desire for change

Tube connection with INOCON – the modular clamp connector system

INOCON specializes in tube connectors and clamp connections: The connecting elements are made of aluminum or stainless steel and fit all standard cross-sections of round and square tubes. A single screw is sufficient to create a reliable, non-slip connection that is resistant to vibrations.

FAQ – Frequently asked questions about connecting tubes

What methods are there for connecting tubes?

A distinction is made between permanent (welding, soldering, gluing, pressing, flanging) and detachable/modular connections (clamp connectors, plug connectors, tube couplings, clamps, etc.).


When are detachable tube connections useful?

When flexibility, reusability, or modular adaptability are important—e.g., in temporary constructions, conversions, prototype construction, or modular systems.


When should welding or a permanent connection be chosen?

For permanent piping, media lines with liquids or gases, or fixed load-bearing structures where no subsequent changes are planned.


For which tube profiles are tube connectors suitable?

For round tubes and square tubes alike — INOCON connectors are designed for both profiles.


What materials are available?

Aluminum, metal, and stainless steel — depending on the load, application, and desired properties such as corrosion resistance or weight.


Are there rotatable or adjustable tube connections?

Yes, flexible and movable constructions are possible with joint, angle, or adjustable clamp connector systems.


Are modular tube systems with clamp connectors reusable or expandable?

Yes, INOCON clamp connectors can be removed and reused multiple times. This makes module and conversion scenarios easy to implement.
