24° Welded Cone Fittings

24° stainless steel welded cone fittings are used wherever the highest standards of pressure resistance, operational safety, and leak tightness are required. The permanent weld to the pipe creates a particularly robust connection for hydraulic systems and industrial piping systems. In combination with the proven 24° connection system according to DIN 3861, welded cone fittings can be flexibly integrated into existing plant designs.

Important information on technical changes, applications, standards and guidelines

Description

Description of a 24° Welded Cone Fitting

Welded cone fittings are pipe connections in which a welded cone is permanently welded to the pipe. The connection to the mating part is then made via a 24° tapered fitting with a union nut. The system combines the advantages of a welded pipe connection with those of a detachable threaded connection.

Unlike cutting-ring fittings or forming systems, no mechanical deformation of the pipe is required. As a result, welded cones are particularly suitable for applications involving high pressure loads, severe vibrations, or increased safety requirements.

Function

Functional Description of a 24° Sealing Cone Screw Connection

The welding cone is welded to the pipe at the end and then forms a single, solid unit with the pipe. Sealing is achieved via the metallic 24° cone in conjunction with the corresponding mating part.

When screwed together, the welded cone is drawn into the 24° internal cone. The resulting surface pressure creates a highly durable and reliable sealed connection. At the same time, the union nut ensures a connection that can be loosened at any time for maintenance and service work.

Applications and Industries

24° weld cone fittings are primarily used in:

  • Hydraulic systems
  • Machinery and plant engineering
  • Press and forming technology
  • Power plant and energy technology
  • Chemical and Process Engineering
  • Offshore and Marine Applications
  • Steel and Metal Industry
  • Hydrogen and Gas Applications
  • Test Benches and Test Facilities
  • Heavy Industry

Welded cones offer a durable and safe solution, especially for high operating pressures, dynamic loads, or critical applications.

Advantages

Exceptionally high operational reliability

Thanks to the material-to-material connection between the pipe and the welding cone, there are no clamping or deforming fasteners on the pipe. This ensures a pipe connection that can withstand long-term loads.

Ideal for high pressure loads

Welded cone fittings are frequently used in systems subject to high operational and pressure-cycling loads.

High vibration resistance

The welded joint prevents relative movement between the pipe and the fitting and increases safety under dynamic loads.

Ease of Maintenance

Despite the fixed pipe connection, the connection to the mating part remains detachable. Components can therefore be easily replaced or maintained.

Corrosion-Resistant Stainless Steel Design

Thanks to the use of high-quality stainless steels, welding cones are also suitable for demanding environmental conditions and corrosive media.

Special Features

Welding cones are often used when maximum process reliability is required or when piping needs to be permanently and securely connected to a 24° screw-on fitting system.

Compared to other pipe connection systems, this results in an extremely compact and robust design. At the same time, the flexibility of the 24° pipe fitting system is maintained, as the connection can be disconnected at any time.

For plant engineers and designers, this offers a cost-effective solution combined with a high level of safety.
